Martial Arts School Video Statistics

Key takeaways

1. Individual instructors and coaches posted 33.7% of the on-topic videos among YouTube’s most-viewed karate class, taekwondo for kids and BJJ for beginners results and drew 36.9% of their views; schools and academies posted 20.0% and drew 29.9%. One taekwondo coach’s channel of children’s clips, which we do not name, drew 22.4% (our read, Nov 8, 2026). (Mark Studios) See details
2. One school carried most of the school share: V-Karate Academy in Tirupur, India, drew 19.0% of on-topic views, and without it schools drew 13.5% of the rest. The 12 U.S.-placed school channels drew 4.6%, and none of the 262 channels in the sample placed itself in Florida. (Mark Studios) See details
3. Videos of 60 seconds or less were 68.3% of the on-topic videos and drew 83.1% of the views. Titles naming children were 21.7% of the videos and drew 39.5% of the views. Only 8 of 80 school videos carried a free trial or enrollment offer in their own text. (Mark Studios) See details
4. No federal series counts martial arts schools alone. All sports and recreation instruction, which includes them, had 20,627 establishments with paid employees and $11.64 billion ($11,640,631,000) in revenue in the 2022 Economic Census, and BLS counted 22,143 private establishments and 191,910 jobs in 2025. (Census and BLS) See details
5. Florida had 1,804 private establishments in all sports and recreation instruction in 2025, 8.1% of the U.S. total; Palm Beach, Broward and Martin counties together had 460 and 2,046 private jobs (BLS; county sums are our calculation). (BLS) See details
6. BLS has no occupation for martial arts instructors. The two shared occupations that can hold them had median annual wages of $47,320 (coaches and scouts) and $46,800 (self-enrichment teachers) in the U.S. in May 2025; coaches and scouts in Florida had $39,370. (BLS) See details
7. CPSC estimates U.S. emergency departments treated 34,538 people for martial arts injuries in 2024, from 891 sampled cases, after 15,820 in 2020. People under 19 made up 35.6% of those visits and children under 13 made up 16.3% (the age shares are our calculation). Our sum of CPSC’s 2025 case file, which CPSC has not yet summarized, is 37,063. (CPSC) See details
8. We could find no public, rigorous national count of people who train. The only national figure we could read, 11.82 million in 2023, is second-hand from a seller’s SEC filing and combines two SFIA reports. USA Taekwondo reported approximately 9,719 individual members for tax year 2024. (Alta Global Group / USA Taekwondo) See details
9. The “90% of fights go to the ground” claim traces to a 1988 LAPD review, as quoted in a 2007 article: 62% of 2,031 altercations from 316,525 arrests ended on the ground. It never counted fights between civilians. (Journal of Non-lethal Combatives) See details
10. IBISWorld’s free pages put the U.S. martial arts studio industry at $21.0bn for 2026, with 72,029 businesses on one page and 76,364 on another; the Census count of every kind of sports instruction with employees was 20,627 establishments in 2022. (IBISWorld and Census) See details
11. 16 Form 10-K filings in 2025 used the phrase “martial arts”, down from 40 in 2011, and 43 of the 78 filed from 2021 through 2025 were tied to combat-sport promotion and media. None came from a company whose main business is running martial arts schools (our count and reading). (Mark Studios) See details

Who makes the most-viewed martial arts class videos on YouTube?

Individual instructors and coaches posted 33.7% of the on-topic videos among the most-viewed karate class, taekwondo for kids and BJJ for beginners videos on YouTube on November 8, 2026 and drew 36.9% of their lifetime views; martial arts schools, academies and dojos posted 20.0% and drew 29.9% (our count). We read YouTube's own view-sorted search results for 'karate class' and 'taekwondo for kids' to the top 200 results each and for 'BJJ for beginners' to the top 50 (the daily search-query limit ran out on the tenth page, so that list is shorter) through the YouTube Data API with no country filter, and classified every channel by hand from its own title, description and video text. It is one view-sorted search on one day, not a census of martial arts video.

The three lists held 408 unique videos from 262 channels, with 12,832,168,096 lifetime views in all. Off-topic videos, mainly CoComelon nursery rhymes with no martial art in the title, took 21.5% of the total views, so we set aside those 7 off-topic videos. That leaves 401 on-topic videos with 10,071,502,528 views; the median one had 6,419,855 views. View counts are lifetime snapshots and include ad views.

The table leaves out a single seller's video (a travel company selling karate trips, with almost no share of views). No general school or daycare appeared in the sample. 41 channels were schools, academies or dojos and 27 were family or personal uploaders (our count). Martial arts class videos often show children, so we publish no channel title, handle or video title for family and personal uploads or for any channel or video whose title names a child: 67 of the on-topic videos, from 44 channels, appear in our tables only as a class and counts.

How much of martial arts YouTube comes from a few channels?

The ten biggest channels drew 63.0% of the on-topic views in our November 8, 2026 sample and the three biggest drew 46.8% (our count). One channel dominates: a taekwondo coach's channel of small children's training clips, which we do not name, drew 22.4% of the views, and a single clip of children at taekwondo training from that channel drew 20.3% on its own, with 2,049,412,701 views. The next most-viewed on-topic video was CoComelon's Taekwondo Song compilation, with 449,412,813 views.

Set that one channel aside and the picture changes: schools and academies drew 38.6% of the remaining on-topic views and individual instructors and coaches 18.7% (our count). The school number leans on another single channel: V-Karate Academy, a karate school in Tirupur, India, drew 19.0% of all on-topic views and 63.6% of school and academy views, and without it schools and academies drew 13.5% of the remaining views. The most-viewed video from a school was a class-activity short from SKY Taekwondo, a U.S.-placed school, with 356,929,806 views.

Where are the martial arts school channels based, and do Florida schools appear?

The most-viewed list is international: 14 of the 41 school and academy channels in our November 8, 2026 sample were in India, and they drew 20.9% of the on-topic views (our count, from each channel's country setting or, where that was blank or differed, the place its own text names). 12 U.S.-placed school and academy channels appeared; they posted 3.7% of the on-topic videos and drew 4.6% of the views. U.S.-placed individual instructors and coaches drew 1.7%. A channel counts as U.S.-placed when its own text names a U.S. place or its country setting is the United States.

Florida does not appear: none of the 262 channels behind the sample placed itself in Florida, so none placed itself in Palm Beach, Broward or Martin County. A search on more queries, or a regional one, might find Florida schools that this view-sorted global search did not.

How do the karate class, taekwondo for kids and BJJ for beginners searches differ?

Schools and academies drew 54.4% of the views for 'karate class', 19.2% for 'taekwondo for kids' and 4.4% for 'BJJ for beginners' (our count, on-topic videos in each list); the 'BJJ for beginners' list is a top 50 and the other two are top 200 lists. V-Karate Academy carries most of the 'karate class' figure: without it, schools drew 22.0% of the on-topic views in that list. Individual instructors and coaches drew 13.2% of the views for 'karate class', 47.1% for 'taekwondo for kids' (19.0% with that list's largest channel, the withheld coach's channel, set aside) and 44.5% for 'BJJ for beginners'. The median on-topic video had 6,791,076.5 views for 'karate class', 7,247,639 for 'taekwondo for kids' and 3,817,008 for 'BJJ for beginners'.

What do the most-viewed martial arts video titles promise?

Titles naming children made 21.7% of the 401 on-topic videos in our November 8, 2026 sample and drew 39.5% of the views, more than any other topic we counted (our count; a title can carry several flags, hashtags count, and film references to The Karate Kid do not count as children). Share of the on-topic videos and of their views by what the title says:

Self-defense is a school topic in this sample: 32 of the on-topic videos naming self-defense in the title came from schools and academies, most of them from V-Karate Academy. Belt tests are not: only 9 titles named a belt test or belt promotion, and 5 of those were family or personal uploads. Few schools sold in the video text: 8 of the 80 school and academy videos carried a free trial or an enrollment offer in the title or description, from 7 channels (our regex over titles and descriptions, read by hand; a phone number alone did not count as an offer unless the title or description asked viewers to join, and we read only each video's own text, so a school may make offers elsewhere).

How long are the most-viewed martial arts videos, and how many are marked for kids?

Videos of 60 seconds or less were 68.3% of the on-topic videos in our November 8, 2026 sample and drew 83.1% of the views; the median short had 7,542,777 views, against 4,419,434 for longer videos (our count). 56.4% of the videos were published in 2024 or later. 40 of the videos were marked made for kids by their uploaders, and those drew 29.2% of the views; 2 of them came from schools and academies. YouTube's altered or synthetic content field was absent from every one of the 408 videos.

How often do U.S. martial arts brands and schools post to YouTube?

We read 17 official channels: 5 U.S. martial arts brands and governing bodies whose channels we could confirm by handle (ATA Martial Arts, United Studios of Self Defense, Gracie University through the Gracie Jiu-jitsu Academy channel, Gracie Barra and USA Judo; we could not confirm channels for Premier Martial Arts, USA Taekwondo, USA Karate, Tiger Rock or 10th Planet under the handles we tried) and the 12 U.S.-placed school channels found in the search sample. In the year to November 8, 2026 they posted 813 videos in all, the median channel posted 29, 2 channels posted 100 or more, and 3 posted nothing: Gracie Jiu-jitsu Academy, JYMOON Taekwondo and James JungHoon Moon (Master Moon's Tae Kwon Do) (our count, from each channel's uploads playlist).

Those uploads had a median of 2,147 views per video, and 51.7% ran 60 seconds or less. The 5 brand and governing-body channels had a median of 613 views per upload; the 12 U.S. school channels from the sample, which already get views, had 3,814. Champions Taekwondo Academy (Copperfield), a U.S.-placed school, posted 166 videos with a median of 5,275 views, and ATA Martial Arts posted 162 with a median of 360. Upload counts come from each channel's uploads playlist; views and subscribers are lifetime snapshots read on November 8, 2026.

Does video instruction or video feedback improve martial arts learning?

Video has helped in small experiments, but mostly against other kinds of video or pictures and not against a live teacher: in a 2020 randomized experiment with 133 first-year physical education students learning the judo throw Ippon-Seoi-Nage, a continuous video produced better learning than three static-picture formats, on tests right after learning and one week later (H’mida, International Journal of Environmental Research and Public Health). They were young adult novices and the study had no live-teacher group. A 2026 randomized study of 24 male secondary school students learning Uchi-mata over four sessions found better two-week retention for those who chose when to watch video models and video of themselves than for a yoked group that viewed at set times (Souissi, Behavior Modification). Both groups had video, so the result is about who controls the viewing.

Other experiments add video to normal practice. In a 2023 study, 20 judoka all did seven days of kata training, and those who also watched five minutes of point-light video, moving dots at the joints and not footage of a person, showed better biomechanical performance and transfer than those who watched neutral videos (Francisco, European Journal of Sport Science). A 2024 randomized study of 30 novices learning a shadow Osoto Gari reported mixed effects on motor skill from training that combined watching footage with motor imagery, with third-person footage reducing error on two measures compared with first-person footage (Chye, Scientific Reports). Video feedback in a warm-up is a different use: in a 2024 crossover study of 20 male kickboxers, video feedback improved two of three kicking tests against a control condition, and adding preferred music improved all three (Boujabli, Sports). That study measured output during a warm-up, not technique learned over time. The oldest study we found is adjacent evidence from fencing: in 1971, 40 college women doing a modified fencing lunge came closer to the taught form when given video-taped feedback with instructions on where to look (Del Rey, Journal of Motor Behavior).

Evidence from inside a school is thinner and weaker. A 2011 conference paper surveyed 196 trainees at a Taekwondo academy about an iPhone Poomsae app the authors built and reported statistically significant differences for education, reregistration and recommendation, with no effect sizes or comparison group in its abstract (Ha, IEEE EMBC proceedings). A 2026 smartphone app for analysing Shotokan Karate stances was tested in a single-participant pilot, on one of its authors, and the paper says the results should not be generalised (Silva, Scientific Reports). In PubMed searches on November 8, 2026, we found no trial that tested recorded video against a live instructor in a martial arts school, and none on learning Brazilian jiu-jitsu technique from video.

What have studies of martial arts videos on YouTube and TikTok measured?

They have not measured quality: in PubMed searches on November 8, 2026, we found no study that scored martial arts, self-defense, MMA or combat-sport videos with DISCERN or a similar tool, and none that counted the share posted by qualified instructors. PubMed does index such scoring studies for physical therapy and rehabilitation exercise videos on YouTube, so the gap is specific to this field.

The closest work describes what was posted. A 2020 content analysis followed 46 pages of Norwegian boxing clubs, athletes and coaches on Facebook from 12 March to 30 June 2020 and analysed 78 posts; online training ranged from live-streamed sessions to at-home videos, and from free to members-only, and the athletes’ most frequent posts were self-promotion (Tjønndal, Frontiers in Sports and Active Living). A 2026 study collected 412 Wushu short videos and 236,627 user comments from TikTok and used machine learning to model what viewers valued; emotional experience drew the most positive feedback, and knowledge and health value were less acknowledged (Chen, Frontiers in Sports and Active Living). Its abstract gives no collection dates and does not say whether the videos were accurate. A 2022 questionnaire study of 451 members of a martial arts group on WeChat, fielded 1 to 5 May 2022, linked social media marketing and user experience to attitudes, norms and attachment, and those to intention to participate (Xie, Frontiers in Psychology). It measured stated intention among people already in such a group, and a one-time survey cannot show cause.

What does research say about online or remote martial arts classes?

Research on online martial arts classes for children, or for students at martial arts schools, is close to absent: the only randomized comparison of online and in-person delivery we found is a 2026 trial of 250 college students learning 24-Style Tai Chi, where attendance was 90% on site, 72% online and 60% for independent practice (Xu, PLOS ONE). Its abstract reports reductions in anxiety and depression for the on-site and mixed groups, self-efficacy gains for the online and mixed groups, and no significant change with independent practice. Tai Chi at a sport university is adjacent evidence, not a test of a karate or jiu-jitsu class.

COVID-era studies mostly describe disruption. Beyond the boxing pages above, a 2025 interview study of 13 Japanese support staff for elite team and combat sport athletes found most relied on online platforms for sessions but considered them inadequate for optimal outcomes (Yamashita, Frontiers in Sports and Active Living). A preliminary 2021 study of 11 elite taekwondo athletes found better changes in sprint and aerobic endurance after twelve weeks of personal isolation training than after detraining, and no significant change in kicking reaction time or flexibility (Sung, International Journal of Environmental Research and Public Health); its abstract does not say the training was delivered by video. In a single-group study of 11 children with autism spectrum disorder, behaviour scores improved after an eight-week adapted judo program and then fell below baseline during an eight-week lockdown, and the abstract does not describe any online substitute (Morales, International Journal of Environmental Research and Public Health).

Prototypes and health trials make up the rest. A 2023 pilot randomized trial with 14 adolescents per group compared a BOXVR game, a guided boxing workout video and no intervention for three weeks, and the BOXVR group ended with lower stress than the guided video group (Cioffi, Games for Health Journal). The title calls the comparison guided YouTube boxing, and the trial measured stress and cognition, not skill. A 2023 test of a pressure-sensing training mat and game with 14 participants reported higher performance and engagement with game feedback on, and two of the authors disclose that they are directors of Lifeform AI (Ishac, Sensors).

Further away still, in the 2026 RETREAT randomized trial, 178 Australian adults with knee osteoarthritis received a website alone or the website plus a twelve-week unsupervised video-based tai chi program, and the tai chi group reported greater improvements in knee pain and function (Zhu, JAMA Internal Medicine). A 2025 pilot of 40 patients with axial spondyloarthritis found no significant difference in total physical activity between remote and hospital-based Tai Chi at month two; the two formats were not randomized against each other, because the pandemic moved delivery online (Fayet, Rheumatology International). These are health studies of adults, reported as published, and are not advice. A 2026 one-arm pilot of 65 women tested a videoconference version of a campus sexual assault prevention program and reported a rise in self-defense self-efficacy (Peitzmeier, BMC Women’s Health). It is not a martial arts class and has no control group. In PubMed searches on November 8, 2026, we found no trial or survey of children’s martial arts classes taught online.

What have trials of martial arts for children actually found?

The largest trial we found, a 2024 cluster randomized trial with 721 children aged 7 to 8 in twenty schools across five European countries, reported small benefits for academic achievement, conduct problems, cardiorespiratory fitness and balance and no benefit for most behaviour measures (Pinto-Escalona, Journal of Sport and Health Science). The effect on academic achievement was d = 0.16, and the comparison was ordinary physical education lessons, which karate replaced for one year. The table lists the controlled and pilot studies in children that we read, with what each reported and what it did not find. Most ran in schools or clinics, and the abstracts do not describe commercial martial arts schools.

Attention and self-regulation results differ measure by measure inside the same trials. The UK Taekwondo trial of 240 children and the Chinese trial of 40 both found gains on some attention measures and none on others, and the wait-list judo trial of 44 preadolescents found fewer errors on one task with no change in motor skills or fitness. Those are task and rating results, not school grades or classroom behaviour over time.

ADHD results are few and mixed. A Basel group reported a higher working-memory score after judo in 57 children with ADHD against a wait-list in 2022, and a combined analysis it published in 2023 found no improvement in response inhibition in the ADHD trial of 63 children. The abstracts do not say whether those participants overlap. A separate 2026 EEG study of 75 youth with ADHD and learning disability used mindfulness martial arts and reported on a brain signal only. None of these is treatment guidance, and this page reports only what each study measured.

Direct evidence on bullying is the thinnest. The 2024 judo pilot with 61 children reported less victimization and no substantial change in bullying behaviors. In the 2021 Rosa trial with 65 participants, judo scores rose 10.21 points on a self-reported provocation and bullying domain, with a smaller rise for ball games and no between-group test in the abstract (Rosa, Sports Medicine - Open). A 2018 paper from the Moore team, titled as an alternative to the anti-bullying approach, reports on 283 students, but its abstract reports resilience and self-efficacy, not bullying, and it does not say whether they are the same students as the 2021 trial (Moore, International Journal of Environmental Research and Public Health).

Not every child responded in the large karate trial. An ancillary analysis within the karate group classed 17% of children as responders on psychosocial functioning and 46% on academic performance, with no comparison group in that analysis (Pinto-Escalona, Scandinavian Journal of Medicine & Science in Sports). None of the abstracts in the table describes video delivery, so these trials say nothing about whether a filmed or online class works, and none reports follow-up beyond about a year. Lakes and Hoyt’s 2004 study, the one most often cited on this subject, is covered in the origins section of this page.

What do systematic reviews conclude about martial arts for children?

Recent reviews warn against broad claims: a 2026 systematic review of 11 longitudinal intervention studies, two randomized and nine quasi-experimental, concluded that the evidence does not show a consistent direction of effect on aggressive behaviour and that martial arts should not be read as having a uniform aggression-reducing effect (Deng, Frontiers in Public Health). A 2026 scoping review of 13 karate studies concluded that conclusions about effectiveness cannot yet be drawn, in part because many studies focus on clinical or special populations (Torzsa, Frontiers in Sports and Active Living).

Other syntheses report positive averages, with limits their abstracts state. A 2026 network meta-analysis found that traditional non-combat martial arts reduced aggression against inactive controls, a standardized mean difference of -0.41, while combat-oriented and multi-style martial arts showed generally weak or non-significant effects; its abstract does not give the number of studies or participants (Wang, Trauma, Violence, & Abuse). A 2026 umbrella review of 30 meta-analyses reported that martial arts had the largest observed point estimate among collaborative bullying-prevention interventions, with no martial arts effect size in the abstract (Li, BMC Medicine). A 2021 meta-analysis of 28 studies of Taekwondo trainees reported positive effects on sociality, character, etiquette and school life adjustment, but all but four of those studies were cross-sectional, so it cannot show that training caused the differences (Kim, International Journal of Environmental Research and Public Health).

Fitness reviews reach firmer but narrower findings. A 2022 systematic review of sixteen studies with 1,615 children reported improvements in physical fitness, based on within-group changes in most studies (Stamenković, Children). A 2025 meta-analysis of 1,314 school-aged and university students across nine randomized and four non-randomized trials found gains in standing long jump and sit-and-reach and no significant difference in VO2max or in overall handgrip strength (Hernandez-Martinez, Frontiers in Physiology). A 2025 review of judo and motor development found that 21 of its twenty-two included studies were observational and only one was a randomized trial (Kowalczyk, Journal of Clinical Medicine).

Two other reviews show how little of this research exists. A 2025 systematic review and evidence gap map of movement programs and child cognition found that programs combining complex movement with rhythm, a group that includes martial arts, dance and gymnastics, made up 15.50% of the studies, a share that covers those activities together (Theroux, Clinical Child and Family Psychology Review). A 2025 review of controlled trials of Olympic combat sports in children and adolescents with disabilities covered twelve studies and 436 participants from 1975 to 2022, reported improvements in several measures and said that inadequate designs call for higher-quality research (Lee, Frontiers in Psychology).

How many Americans train in martial arts?

The only national figure for martial arts training we could read in public is approximately 11.82 million people in 2023, and it is second-hand. It comes from a November 2023 SEC registration statement by Alta Global Group, a company that sells martial arts training products, which attributes it to two SFIA reports, Martial Arts and Boxing Fitness (SEC filing). A later annual report by the same company, renamed Mixed Martial Arts Group, says more than 11.8 million people took part in 2023 (SEC filing). Neither filing gives the split between the two reports, the sample or the field dates. Because it draws on two lines, it is not a count of martial arts alone.

We could not find a public, rigorous national count of people who train in martial arts, and we found no published federal estimate. SFIA, the Sports & Fitness Industry Association, is the only survey we found that tracks the activity nationally, and it does not publish the martial arts number on a public page. Everything else counts something narrower. The table below sets the sources side by side, and the gap between them is the point: each one counts a different thing.

The figures are far apart for a reason. SFIA’s survey asks a weighted online panel about a rolling 12 months, governing bodies count people who pay to join, and high school associations count roster spots on sanctioned school teams. A member of a dojo who never joins a federation can appear only in the first. None of them is a count of everyone who trains.

What does SFIA’s participation survey measure, and who can read the martial arts line?

SFIA’s participation numbers rest on 18,000 online interviews during calendar 2025, drawn from U.S. online panels of people ages 6 and older and run through the Physical Activity Council (PAC 2026 report). The results are weighted to about 310.6 million people (310,635,717) (PAC 2026 report). For a sport with a five percent participation rate, the council gives a confidence interval of plus or minus 0.32 percentage points at the 95 percent level (PAC 2026 report). Activity is reported as a rolling 12-month rate. On that basis SFIA says 250 million Americans age 6+ took part in at least one sport, fitness or leisure activity in 2025, the first time SFIA has recorded that level (SFIA).

The council’s 2026 report names Martial Arts and MMA for Competition among the individual sports it tracks (PAC 2026 report), but it prints no participant number for them. SFIA is a trade association whose members sell into this market, and it charges for its research: its 2026 Topline report is free to members and $700 for non-members (SFIA), and it offers 92 single-sport reports (SFIA). One of them is the 2026 Martial Arts Participation Report, whose public page carries a title and no figures (SFIA). We could not read the number at the source.

The line names have also moved. The 2023 report listed Boxing for Fitness and MMA for Fitness as separate individual-sport lines (PAC 2023 report). The 2026 report lists a single Boxing/MMA for Fitness line under fitness activities (PAC 2026 report). A series built from the old names and the new ones is not automatically like for like.

The older public trail is thin and second-hand. A 2016 trade-blog post repeating SFIA’s State of the Industry report put MMA for competition at 749,000 people in 2012 and at 1.29 million in 2015, and MMA for fitness at 1.8 million (1,789,000) in 2012 and 2.5 million in 2015 (MMA Payout). It described the survey as a nationwide online survey of 32,658 Americans taken in 2015 (MMA Payout). That is a blog repeating a seller’s report, and it covers only the MMA lines, so read it as a pointer to the direction, not as a measurement we confirmed at the source.

How many high school students compete in martial arts through their school?

NFHS counted 1,376 high school participants in judo and martial arts combined in 2025-26 (our calculation). That is 1,346 in judo and 30 in the Martial Arts line, counted as roster spots by state associations (NFHS). Hawaii accounts for most of the judo count, with 694 boys and 514 girls (NFHS). California is the only state reporting a martial arts line in 2025-26 (NFHS).

The year before, NFHS counted 1,288 in judo (NFHS) and 52 in martial arts across three reporting states (NFHS). As a contrast, wrestling had 384,030 participants in 2025-26 (NFHS), up from 374,278 in 2024-25 (NFHS). That is about 279 wrestling roster spots for every judo or martial arts spot (our calculation). Judo and martial arts together were 0.016% of the 8.4 million (8,415,684) high school sports participants NFHS counted in 2025-26 (our calculation) (NFHS). NFHS counts only sports that state associations report, and a student on several teams counts once per team. It says nothing about commercial martial arts schools or community dojos.

How many members do U.S. martial arts governing bodies report?

USA Taekwondo reported approximately 9,719 individual members in its Form 990 for tax year 2024, a filing to the IRS in which the body describes its own programs (Form 990). These are the body’s own counts, stated in the narrative of its return. They count memberships in the national governing body, and most people who train at a local school never join one.

By its own figures, USA Taekwondo’s individual membership fell 30.6% from tax year 2019 to tax year 2024 (our calculation). The filings call these numbers approximate, and the same figure appears in several consecutive returns, so read the series as a rough shape, not an annual count. The same returns say approximately 4,000 athletes took part in its domestic and international competitions in 2024 (Form 990), against approximately 6,200 in 2019 (Form 990). The 2024 return also says the Dan office processed approximately 599 domestic and international certifications (Form 990).

USA Judo’s Form 990 for tax year 2024 says it provides insurance to over 13,000 members (Form 990). Its return for tax year 2023 says approximately 10,000 (Form 990). Its return for tax year 2016 gave the same approximate figure, 10,000 (Form 990), so the number looks like a round estimate. The United States Judo Federation, a separate body, reported 7,776 members and 245 clubs and dojos in its return for the year ended August 2024, when it says 217 black belts were awarded (Form 990). Its return for the year ended August 2016 said over 11,371 members and 340 clubs and dojos (Form 990), a fall of 31.6% in members between those two returns (our calculation).

AAU, USA Boxing, USA Karate and World Taekwondo do not appear here because their websites do not permit automated reading, and USA Boxing’s Form 990 prints no member count. These 990 figures are the part of the record we could read and check.

Which martial arts are on the Olympic program?

For Los Angeles 2028, the LA28 organising committee’s list includes Taekwondo, judo, boxing and wrestling, and karate is not on it (LA28). Karate made its full Olympic debut at Tokyo 2020, where the International Olympic Committee says 80 athletes competed (IOC). The organising committee says judo debuted at the Olympics in 1964 for men (LA28) and that taekwondo became an official medal sport at the Sydney 2000 Games (LA28). It also says taekwondo is practiced in over 200 countries (LA28), without giving a source or method. The program says which disciplines are contested. It says nothing about how many people train in them.

What does YouTube say about sparring and self-defense video?

None of the YouTube policy pages we read on November 8, 2026 uses the term martial arts, so sparring and self-defense clips fall under general wording. YouTube’s violent or graphic content policy gives beatings or brawls outside the context of professional or professionally supervised sporting events as an example of what it does not allow (YouTube Help). That is an exception inside a banned example, and the page does not say supervised sparring is always allowed. For children the page draws a narrower line: it bars actual schoolyard fights between minors and says it may allow content if minors are only play fighting and that is evident to viewers (YouTube Help).

Context has to be in the video itself. YouTube says educational context for violent or graphic material must appear in the images or audio, and that the title or description is not enough (YouTube Help). Content that stays up with an age restriction cannot be seen by anyone under 18 or signed out (YouTube Help).

YouTube’s harmful or dangerous content policy has passages close to martial arts material, and none of them names it. It lists asphyxiation, any activity that prevents breathing, among extremely dangerous challenges, with choking games as its example (YouTube Help). It lists misuse of weapons without proper safety precautions (YouTube Help). It bars instructions for activities meant to kill or severely harm others (YouTube Help). YouTube does not say how these apply to chokes taught on a mat, weapons forms or self-defense classes, and this page does not guess. The same policy says YouTube may age-restrict instead of removing a dangerous act when the video has educational context, which could include the precautions or training needed to do it safely (YouTube Help).

YouTube’s advertiser-friendly guidelines are the one page we read that addresses this material directly. Under content that can earn ad revenue they list self-defense moves shared as a tutorial (YouTube Help) and combat sports such as boxing in a professional setting, such as a fitness center or arena (YouTube Help). A focal or prolonged display of street fights in a non-educational context earns no ads, even without injuries (YouTube Help). These rules cover ad eligibility only, not whether a video may stay up.

What does YouTube say about videos of children in martial arts classes?

YouTube’s child safety policy, read November 8, 2026, does not mention martial arts, and it says content that depicts children and breaks no rule may still have some features disabled at the channel and content level, with comments first on its list (YouTube Help). Live streams with minors under 16 who are not visibly accompanied by an adult may be removed or lose live chat (YouTube Help). The page asks that a minor be supervised by an adult and doing age-appropriate activities, and it names public performances as an example (YouTube Help). It says to avoid attire that overexposes a minor or is form-fitting, with no stated exception for training wear (YouTube Help).

Some of the page’s examples of content not allowed come closer to kids’ martial arts. One is fight or bullying content featuring kids without educational, documentary, scientific or artistic context and blurring (YouTube Help). Another is showing minors in dangerous activities, for example physical stunts or using weapons or explosives (YouTube Help). The page does not address supervised sparring or training weapons, and it does not say how those examples apply to a class.

Separately, YouTube requires uploaders, wherever they are, to state “whether or not your videos are made for kids,” under an agreement with the US Federal Trade Commission (YouTube Help). It treats a kid in the United States as anyone under the age of 13 (YouTube Help). It also says a video is not necessarily made for kids just because it covers an activity traditionally associated with children (YouTube Help). The page does not say how to classify a kids’ program promo, and YouTube says it cannot give legal advice.

What do YouTube’s rules say about music on class and promo clips?

YouTube says every video uploaded to the platform is automatically scanned by its Content ID system against audio and visual files from copyright owners (YouTube Help, read November 8, 2026). The page does not mention martial arts, so a class or promo clip with a commercial track falls under the general rule. The copyright owner, not YouTube, chooses the outcome, and the first one YouTube lists is “Blocks a video from being viewed” (YouTube Help).

YouTube’s copyright myths page says someone who purchased a song does not thereby own the rights to upload it (YouTube Help). It also says “Not trying to make money from copyrighted content doesn’t prevent copyright issues” (YouTube Help). A live stream can be “interrupted even if you’ve licensed” the content, unless the owner adds the channel to its Content ID allowlist (YouTube Help). Content ID made 2,502,941,368 copyright claims in calendar year 2025, across all uploads (YouTube Copyright Transparency Report). YouTube publishes no figure for martial arts. The dance studio statistics page covers YouTube’s separate music rules for Shorts.

How many videos does YouTube remove for child safety and violence?

YouTube individually removed 11,159,676 videos for Community Guidelines violations from April to June 2026, worldwide and across all categories, by its own transparency report (YouTube). Of those, 7,614,835 were removed for child safety (YouTube), 585,313 as violent or graphic (YouTube) and 565,917 as harmful or dangerous (YouTube). YouTube publishes no figure for martial arts, so these totals cannot show how often a school’s video is removed, and each category covers far more than filmed classes.

Why are Instagram, Facebook and TikTok rules not quoted here?

This page does not quote those platforms’ rules because the robots files on Facebook, Instagram and TikTok bar AI agents from the pages that state them, and we do not rely on copies of those pages. Each platform’s current rules should be read directly before class or kids’ program video is posted there.

How many schools do martial arts software sellers say they serve?

Companies selling software to martial arts schools publish their own customer counts, and none of the counts below is audited. Kicksite says it has served 8K+ schools, without saying whether that means current customers (Kicksite, read November 8, 2026). Spark Membership says “More than 2,000 martial arts schools” run on its software, in a sentence that also lists dance, gymnastics and yoga (Spark Membership). It says “More than 500 new schools” adopted it during the COVID-19 pandemic to move online, and it gives no survey or dates (Spark Membership).

Larger sellers count every kind of customer. Zen Planner said in October 2026 that it is trusted by 5,000+ fitness businesses (Zen Planner, Internet Archive capture), and Mindbody says “More than 40,000 businesses” use its software (Mindbody). Neither breaks out martial arts. Sellers’ customers can overlap, so these counts cannot be added into a total of schools.

Kicksite and Zen Planner have also surveyed school owners. The landing pages for those reports give no field dates and the results sit behind download forms, so this page prints no results from them.

What does Gymdesk’s 2026 benchmark say about how schools run?

Gymdesk, which sells gym software, published a benchmark in June 2026 drawn from 4,594 active gyms on its own platform, the large majority of them martial arts and combat-sports schools (Gymdesk). The figures come from its billing and attendance records, so they describe Gymdesk’s customers and not schools in general. It reports that 78% of those gyms run a kids program (Gymdesk). Gyms with a kids program average roughly 237 members (Gymdesk), against 107 at adults-only gyms (Gymdesk).

Out of 175,000 real free trials, a count that excludes comped and staff memberships (Gymdesk), 73% became paying members (Gymdesk). Gymdesk also reports that 43.2% of active gyms mark attendance by hand (Gymdesk), a practice its own product replaces. Its revenue table covers 4,196 gyms with complete data (Gymdesk) and shows average monthly revenue of $2,632 at gyms under 50 members (Gymdesk) and $26,821 at gyms of 200 or more (Gymdesk).

What did Gold BJJ’s survey of jiu-jitsu students report?

Gold BJJ, which sells jiu-jitsu gear, ran a State of Jiu Jitsu survey in late 2024 and early 2025 that drew nearly 2,000 responses from practitioners (Gold BJJ). Respondents chose to answer and Gold BJJ publishes no exact field dates, so the results describe that group alone. United States respondents reported average monthly dues of $146.15 (Gold BJJ). Florida respondents reported $156.67, from a Florida respondent count the page does not give (Gold BJJ). Among all respondents, 43.6% said they had competed in the past two years (Gold BJJ).

How big are online martial arts curriculum sellers by their own numbers?

The one enrollment count we found is Gracie University’s homepage counter, which read 493,551 students (Gracie University, Internet Archive capture) in 196 countries and territories on October 7, 2026 (Gracie University, Internet Archive capture). The counter does not say whether those students are active or paid. BJJ Fanatics advertises “Over 3000 Instructional Videos” (BJJ Fanatics, read November 8, 2026), a product count and not a customer count. Jiu-Jitsu X lists 5000+ techniques and systems (Jiu-Jitsu X, read November 8, 2026). Black Belt magazine describes an audience of hundreds of thousands of martial artists, with no circulation figure or definition (Black Belt, Internet Archive capture). These are the sellers’ own descriptions, and we found no audit of any of them.

How many martial arts instructors work in the United States?

The Bureau of Labor Statistics (BLS) does not count martial arts instructors on their own. The federal occupation system has no code for them, and the two shared occupations that can hold them had 248,950 and 332,110 wage and salary jobs in the United States in May 2025. The first figure is Coaches and Scouts (SOC 27-2022), which covers coaches of every sport and scouts (BLS). The second is Self-Enrichment Teachers (SOC 25-3021), which also covers teachers of music, art, languages and other subjects outside degree programs (BLS). Both come from BLS’s Occupational Employment and Wage Statistics (OEWS) survey, which counts people on an employer’s payroll in any industry. OEWS leaves out the self-employed and does not split either code by sport or subject.

BLS Employment Projections add the self-employed. They put Coaches and Scouts at 298.8 thousand jobs in 2025 (BLS) and Self-Enrichment Teachers at 419.1 thousand (BLS). Self-employed workers held 8.3% of coach and scout jobs (BLS), about 24.8 thousand, and 14.9% of self-enrichment teaching jobs (BLS), about 62.4 thousand, computed from BLS’s rounded figures (our calculation). BLS’s Occupational Outlook Handbook page for coaches and scouts does not mention martial arts (BLS).

Where do coaches and self-enrichment teachers work?

Educational services employed 64% of U.S. coach and scout jobs in 2025, including self-employed workers, according to BLS’s Occupational Outlook Handbook (BLS). That group covers state, local and private schools of every kind, so it is not a count of martial arts studios.

Other Schools and Instruction (NAICS 611600), the industry group that holds sports, fine arts, language and driving schools and tutoring, employed 61,090 U.S. coaches and scouts on a payroll in May 2025, per BLS OEWS (BLS). That is 24.5% of the occupation (our calculation). The same group employed 184,830 self-enrichment teachers (BLS), 55.7% of that occupation (our calculation). BLS publishes no OEWS estimate for sports and recreation instruction (NAICS 611620) alone.

How much do coaches and self-enrichment teachers earn?

The median annual wage for U.S. Coaches and Scouts was $47,320 in May 2025, per BLS OEWS (BLS). That is 7.2% below the $50,980 median for all U.S. occupations (BLS) (our calculation). The 10th percentile was $28,790 (BLS) and the 90th percentile was $98,860 (BLS). BLS reports this occupation’s pay as annual figures only, with no hourly series.

The median annual wage for U.S. Self-Enrichment Teachers was $46,800 in May 2025 (BLS), 8.2% below the median for all occupations (our calculation).

These figures cover workers on a payroll in any sport or subject. They do not show what a martial arts instructor earns, and they leave out school owners who take profits rather than a wage.

Will there be more coaching and self-enrichment teaching jobs by 2035?

BLS projects 6.1% growth for Coaches and Scouts from 2025 to 2035 in its Employment Projections, which count the self-employed (BLS). That is faster than the 3.5% projected for all U.S. occupations (BLS). It projects 3.5% growth for Self-Enrichment Teachers over the same period (BLS), the same rate as all occupations.

BLS expects about 36.4 thousand openings a year for coaches and scouts (BLS) and about 50.0 thousand for self-enrichment teachers (BLS), on average, over the decade. Those openings include workers who leave the occupation or the labor force, not only new jobs. Neither projection is specific to martial arts.

How many coaches and self-enrichment teachers work in Florida and South Florida, and what do they earn?

Employers in Florida counted 18,120 coaches and scouts (BLS) and 11,800 self-enrichment teachers (BLS) on a payroll in May 2025, per BLS OEWS. That is 7.3% of U.S. payroll coaches and scouts and 3.6% of U.S. payroll self-enrichment teachers (our calculation). Both codes are shared, so these counts cover instructors of every sport or subject, not martial arts instructors alone.

In May 2025, Florida’s median annual wage was $39,370 for coaches and scouts (BLS), 17.8% below the state’s $47,880 median for all occupations (BLS) (our calculation). For self-enrichment teachers it was $45,830 (BLS), 4.3% below that median (our calculation).

The Port St. Lucie metro area, which holds Martin County, has small estimates with relative standard errors of 11.8% for coaches and scouts (BLS) and 12.6% for self-enrichment teachers (BLS). OEWS publishes no estimate for these occupations in the West Palm Beach or Fort Lauderdale metropolitan divisions, and none for any county.

Does any federal agency count martial arts schools?

No federal program publishes a count of martial arts schools. The closest figure in the 2022 Economic Census is 20,627 U.S. establishments with paid employees in all sports and recreation instruction (NAICS 611620) (Census). The 2022 NAICS Manual names “Martial arts instruction, camps or schools” as an example of that industry (OMB, NAICS Manual). The same code holds gymnastics, swimming, golf, baseball, cheerleading, riding and other sports instruction, so every figure below counts all of them together.

The 2022 Economic Census has no martial arts instruction line. We searched every product line label in its education and recreation sectors and in its all-industries product table for martial, karate, self-defense, taekwondo, judo, jiu-jitsu and boxing, and found none. Its kind-of-business table covers construction only. Any statement that federal data show a specific number of martial arts schools is not drawn from these sources.

How many sports and recreation instruction businesses are there?

BLS’s Quarterly Census of Employment and Wages (QCEW) counted an annual average of 22,143 private establishments in all sports and recreation instruction in the United States in 2025 (BLS). That code covers martial arts schools together with gymnastics, swim, golf and other instruction. In 2019 the count was 17,550 (BLS), so it rose 26.2% in six years (our calculation). QCEW counts worksites with employees covered by unemployment insurance. A chain counts once per location, and instructors with no payroll are not in it.

These employers had an annual average of 191,910 workers in 2025 (BLS), 32.6% more than the 144,728 of 2019 (BLS) (our calculation). Employment fell 24.7% to 108,973 in 2020 (BLS) (our calculation). In 2025 that works out to an average of 8.7 workers per establishment (our calculation). Average annual pay was $24,013 (BLS). That average spreads total wages over every worker, part-time and full-time, so it sits well below a full-time salary.

The Census Bureau counts these businesses from its own register. County Business Patterns counted 20,916 U.S. establishments with paid employees in 2023 (Census), up 39.5% from 14,996 in 2013 (Census) (our calculation). It counted 176,751 paid employees in March 2023 (Census). The 2022 Economic Census counted 19,703 employer firms (Census). QCEW averages state unemployment-insurance records over the year, so its count and the Census counts never match exactly. All of these figures are for all sports and recreation instruction.

How much revenue do sports and recreation instruction businesses bring in?

U.S. sports and recreation instruction establishments with paid employees had revenue of $11.64 billion ($11,640,631 thousand) in 2022, according to the 2022 Economic Census (Census). That is about $564,300 per establishment (our calculation), across all of NAICS 611620, not martial arts schools alone. The Census Bureau’s Annual Integrated Economic Survey, a sample of firms, put revenue at $12.73 billion ($12,732,040 thousand) in 2024 (Census), up 8.0% from 2023 (Census). The survey total is not directly comparable with the Economic Census count. Both leave out instructors with no employees.

The closest product line in the 2022 Economic Census covers leisure and recreational instruction in sports, exercise and nature appreciation, excluding sports coaching services. It made up 89.0% of the industry’s revenue (Census), or $10.37 billion ($10,365,087 thousand) (Census). It is the line that comes closest, and it is not a martial arts line.

Revenue is spread across many firms. The four largest firms held 5.9% of it in 2022, according to the 2022 Economic Census (Census).

How many sports instructors run a business with no employees?

Census Nonemployer Statistics publishes no line at or below sports and recreation instruction, so a federal count of solo martial arts instructors does not exist. Requests for NAICS 611620, 61162 and 6116 returned no data for 2024 and 2023. The lowest level published is NAICS 611, all educational services. Census counted 924,679 businesses with no paid employees in that sector in 2024 (Census), and that count cannot be split by subject.

In 2023, the latest year both programs cover, Census counted 893,520 such businesses (Census) beside 118,004 employer establishments in NAICS 611 (Census). That is 7.6 businesses with no employees for every employer establishment across all educational services (our calculation). It is not a measure for martial arts.

How much do education businesses spend on advertising?

U.S. educational services employer firms spent $3.27 billion ($3,266,271 thousand) on purchased advertising and promotional services in 2024, per the Census Bureau’s Annual Integrated Economic Survey (Census). That covers every private school, college, training firm and instruction business with employees (NAICS 61), not sports instruction alone. The survey publishes no advertising figure for NAICS 611620, 6116 or 611, and the Annual Business Survey datasets we checked carry no advertising item. The figure counts money paid to agencies, ad platforms, media and printers, not staff time, and it is not split by medium, so the share spent on video is not known.

How many sports and recreation instruction businesses are there in Florida and in Palm Beach, Broward and Martin counties?

BLS QCEW counted an annual average of 1,804 private establishments in all sports and recreation instruction in Florida in 2025 (BLS), 8.1% of the U.S. total (our calculation), up 31.1% from 1,376 in 2019 (BLS) (our calculation). They employed an annual average of 11,191 workers (BLS) at average annual pay of $32,371 (BLS).

County Business Patterns counted 1,759 establishments with paid employees in Florida in 2023 (Census), up 61.1% from 1,092 in 2013 (Census) (our calculation). The 2022 Economic Census counted 1,668 (Census), with revenue of $1.01 billion ($1,014,925 thousand) (Census). These are all sports and recreation instruction, never martial arts schools alone.

Together the three counties had 460 private establishments in 2025, per BLS QCEW (our calculation), 25.5% of Florida’s (our calculation), and 2,046 private jobs (our calculation), 18.3% of the state’s (our calculation). County Business Patterns counted 455 establishments with paid employees in the three counties in 2023 (our calculation), 25.9% of Florida’s (our calculation). The 2022 Economic Census counted 438 (our calculation), 26.3% of Florida’s (our calculation). Federal data do not count martial arts schools in any of the three counties.

How many martial arts injuries reach U.S. emergency departments?

U.S. emergency departments treated an estimated 34,538 people for injuries associated with martial arts in 2024, according to the Consumer Product Safety Commission’s National Electronic Injury Surveillance System, known as NEISS (CPSC NEISS Data Highlights). That national estimate comes from 891 sampled cases, works out to 10.3 injuries per 100,000 people, and carries a coefficient of variation of .11, CPSC’s own measure of sampling error (CPSC). NEISS samples hospitals and weights each case up to a national estimate.

CPSC files these injuries under product code 3257, “Martial arts (activity, apparel or equipment),” the code its manual’s index gives for karate, judo, jujitsu, kickboxing and kung fu (CPSC coding manual). Boxing (1207) and wrestling (1270) have their own codes and are not in these counts (CPSC coding manual). The counts cover emergency-department treatment only. Injuries seen at a doctor’s office or never treated are not in NEISS, and NEISS has no count of people training, so these figures are not injury rates per student.

CPSC’s estimate fell to 15,820 in 2020 and rose every year after that. A higher count can reflect more people training, more people choosing an emergency department, or the sample itself, and NEISS cannot separate those. CPSC produced its 2024 estimates from a sample of 100 hospitals, against 96 in 2023 (CPSC 2024 Highlights) (CPSC 2023 Highlights), so compare across that change with care.

For 2020 through 2024 the table prints CPSC’s published row, and our own sums of the case-file weights reproduced each of those estimates. The 2016 to 2019 rows are our sums of the archived case files, with no CPSC table used for them (our calculation). We read CPSC’s files through Internet Archive captures because cpsc.gov refused scripted requests. CPSC has posted its 2025 case file but no 2025 Data Highlights, so the 2025 row is our sum of that file, which we read in a browser because cpsc.gov refuses scripted requests and the Internet Archive holds no copy. We did not calculate standard errors for our own sums, and we did not read or use case narratives.

Who gets hurt in martial arts, and how?

People under 19 made up 35.6% of estimated martial arts emergency visits in 2024, from 415 sampled cases, and children under 13 made up 16.3%, from 215 sampled cases (our calculation from the CPSC case file). Females accounted for 23.1%, from 214 sampled cases (our calculation), or 7,993 estimated visits in CPSC’s table (CPSC). In the 2025 case file, people under 19 made up 38.1% of the estimated visits and children under 13 19.4% (our calculation).

The “other or not stated” diagnosis code was larger than any named diagnosis in 2024, so the two diagnosis rows are not a full list. Most patients were treated and released: CPSC lists 33,604 people that way in 2024 and 934 in its “Hosp. & DOA” column (CPSC). In the case file, that column’s 2024 total matches patients who were transferred, admitted or held for observation, and it rests on only 24 sampled cases (our calculation), so treat it as rough.

What do published studies find about martial arts injuries?

One published NEISS study estimated 310,143 martial arts injuries in U.S. emergency rooms from 2009 to 2019, from 8,400 recorded cases of all ages (Bickley et al., Injury, 2023). Published NEISS studies use different case definitions, ages and years, so their totals should not be compared with one another or with the CPSC rows above.

• Children: Madireddy and colleagues estimated 176,947 emergency visits among children aged 3 to 17 from 2004 through 2021, from 5,656 NEISS cases. Among those injured children, competition carried 2.56 times the risk of a head or neck injury compared with formal class, horseplay and unspecified activity (Madireddy et al., Am J Sports Med, 2023).
• A 2026 retrospective NEISS study of 2015 to 2024 by Hamstra-Wright and colleagues reported a national estimate of 277,753 injuries from 7,613 cases (Hamstra-Wright et al., Injury, 2026).
• Concussion, emergency data: a NEISS study of 2012 to 2016 reported mild traumatic brain injury in martial arts at 61.0 per 100,000 person-years, below boxing and wrestling (Lemme et al., Clin J Sport Med, 2020). A NEISS study of 2013 to 2022 analyzed 581 martial arts concussion cases and found 96.4% were treated and released (Kiehl et al., Injury, 2025).
• Concussion, surveys: at the 2022 World Karate Championships for cadets, juniors and under-21 athletes, 29.9% of 654 questionnaire respondents reported one or more concussions in karate training or competition (Augustovicova et al., Injury Prevention, 2025). In a survey of 778 U.S. adult Brazilian jiu-jitsu practitioners, lifetime self-reported concussion from the sport was 25.2% (Spano et al., Sports, 2019). Both are self-reported.

Tournament and training studies count differently, per bout, per athlete-exposure or per hour, and their rates do not carry over to an ordinary class.

• A systematic review and meta-analysis of 28 prospective cohort studies of Olympic-style karate competition estimated 88.3 injuries per 1,000 athlete-exposures (Lystad et al., BJSM, 2020).
• Physicians at French Judo Federation competitions recorded 421,670 fights from 1993 to 2014, with an injury incidence proportion of 1.1% (Frey et al., Orthop J Sports Med, 2019).
• A prospective record of 1,020 bouts at three World Karate Championships for 14- and 15-year-olds (2009, 2011 and 2013) found 3 time-loss injuries (Arriaza et al., Am J Sports Med, 2016). These were elite cadets.
• A survey of 881 Brazilian jiu-jitsu practitioners who trained at least weekly, fielded online and at Dutch competitions in February and March 2024, reported 5.5 injuries per 1,000 hours of training, and 89% of reported injuries happened in training (Stegerhoek et al., BMJ Open Sport Exerc Med, 2025). Respondents chose to answer and reported from memory.

What is known about injuries from chokes?

A 2026 scoping review, searching through October 2024, found 40 individual published cases of blunt cerebrovascular injury in martial arts, from chokeholds, whiplash and direct blows (Hyler et al., J Clin Neurosci, 2026). Published cases have no denominator, so they cannot give a rate.

A 2020 web survey analyzed 4,307 visitors to two combat sports forums, and 0.05% reported ongoing symptoms from chokes (Stellpflug et al., Phys Sportsmed, 2020). The respondents were a self-selected convenience sample, so the survey cannot show how often serious harm happens. A 2022 case series from the same lead author described 10 cases of cervical artery dissection or ischemic stroke associated with sportive chokes (Stellpflug et al., J Emerg Med, 2022). A video analysis of 7,426 bouts at Judo World Championships from 2015 to 2021 recorded 39 cases of unconsciousness from shime-waza, judo’s choking techniques (Sasaki et al., J Sci Med Sport, 2022). These studies describe what was recorded; none of them rates a school, style or instructor.

How often do public companies mention martial arts in their annual reports?

16 Form 10-K annual reports filed with the SEC in 2025 contain the phrase “martial arts”, by our count in EDGAR full-text search, down from 40 in 2011, the peak year (the yearly counts for 2001 to 2025 are in our EDGAR counts CSV). From 2001 to 2025, 403 filings from 140 filers used the phrase (our count).

The count covers Form 10-K filings only, each filing counted once. It matches the exact phrase anywhere in a filing or its exhibits, so it counts mentions, not companies in the martial arts business. Most of the mentions are about fights: 230 of the 403 filings, or 57.1%, use the longer phrase “mixed martial arts” (our count). 226 also contain the word video somewhere in the same document (our count), which says little on its own because a 10-K is a long document.

This section covers SEC filings only. Martial arts franchise disclosure documents, with their outlet counts and investment ranges, are not included: the Minnesota filing database refused our automated requests when we collected this data.

What are those filings actually about?

Fight promotion and fight media, not schools: 43 of the 78 Form 10-K filings filed from 2021 through 2025 that contain the phrase are tied to combat-sport promotion and media, by our reading of each filing. 0 come from a company whose main business is running martial arts schools (our reading). The nearest is B2Digital, a fight promoter that reported operating two gyms with MMA training resources (B2Digital 10-K for fiscal 2022).

Schools mostly appear as someone else’s customer or borrower. NewtekOne’s schedule of investments at December 31, 2022 lists 3 term loans to businesses with Martial Arts in their name, 2 of them trading as Premier Martial Arts (our count). EverCommerce, which sells software to small service businesses, said in its 10-K for fiscal 2023 that software for instructional dance and martial arts centers had emerged in recent years (EverCommerce 10-K for fiscal 2023); its 10-K for fiscal 2025 no longer uses the phrase martial arts. It paid $33.2 million in 2019 for a billing provider serving health clubs, fitness clubs and martial arts studios (EverCommerce 10-K for fiscal 2021); that price covers all of those customers, not martial arts studios alone. In its 10-K for fiscal 2010, Markel listed martial arts and dance schools among the organizations one of its insurance divisions covers (Markel 10-K for fiscal 2010), and Life Time named martial arts among the programs at its centers (Life Time 10-K for fiscal 2014). None of the passages we read gives a count of martial arts customers.

The school and studio phrases are rarer. 19 of the 403 filings contain “martial arts school” or “martial arts studio”, singular or plural (our count). 7 of them come from companies that sell to those schools or studios, such as Everlast, which planned to focus on fitness clubs and martial arts studios for its sporting goods equipment (Everlast 10-K for fiscal 2006). 6 use the phrase in the biography of an officer or director (our reading). Landlords rarely name them: 8 of the 403 filings came from REITs or real estate companies, and 2 of those name a martial arts business as a tenant or in a lease list (our reading).

Teaching video does not appear in the recent filings. In 8 of the 78 filings the word video falls within 300 characters of martial arts (our reading). Those passages describe home videos of fights, one company’s history in television and video, and ESPN+ programming. None concerns teaching martial arts on video.

What does UFC’s owner report about its video reach?

UFC events are broadcast to over 950 million TV households, TKO Group Holdings says in its 10-K for fiscal 2025 (TKO 10-K for fiscal 2025). It says UFC produces more than 40 live events a year (TKO 10-K), and that as of December 31, 2025 UFC had approximately 350 million social media followers (TKO 10-K) and more than 700 million fans (TKO 10-K). These are the owner’s own figures. Its risk factors say its methods for tracking fans and followers are subject to limitations.

UFC also sells video directly. TKO describes UFC FIGHT PASS as offering early preliminary bouts and a video-on-demand library of historical and original content (TKO 10-K), with subscriptions of up to 12-month access (TKO 10-K). The passages we read give no subscriber count. U.S. rights moved in 2026: Disney lists mixed martial arts among ESPN’s rights only through the end of calendar 2025 (Disney 10-K for fiscal 2025), and TKO reports a seven-year partnership with Paramount announced in August 2025 (TKO 10-K). These numbers describe professional fight media. They do not measure what a school’s own videos do.

How do 10-K filings repeat martial arts market figures?

One filer moved the same research firm’s figure between worldwide and U.S. labels. Rebel Group, a fight promoter, cited IBISWorld’s Martial Arts Studios report for $3 billion in mixed martial arts revenue worldwide in its 10-K for fiscal 2015 (Rebel Group 10-K for fiscal 2015), $4 billion worldwide in its 10-K for fiscal 2017 (Rebel Group 10-K for fiscal 2017), and 4 billion USD for MMA in the U.S. in its 10-K for fiscal 2019 (Rebel Group 10-K for fiscal 2019). 4 of the 19 school and studio filings are Rebel Group quoting that report title (our reading). We did not read the paid report, so these rows record what the filings say.

Hanryu Holdings, a Korean culture app company, says in its 10-K for fiscal 2023 that approximately 100 million people practice taekwondo (Hanryu Holdings 10-K for fiscal 2023). The sentence names no source for the figure, a filing’s passing statement is not a count of participants, and the company’s newest 10-K, for fiscal 2025, no longer uses the word taekwondo.

Does Florida's health studio law cover a martial arts school?

It can, and the exemption depends on an affidavit: the 2026 Florida Statutes define a health studio as anyone selling instruction, training or assistance in a program of physical exercise (s. 501.0125), and let a program used solely for dance, aerobic exercise or martial arts that utilizes no physical exercise equipment be declared exempt (s. 501.013(1)(d)) upon the filing of an affidavit with the Department of Agriculture and Consumer Services (s. 501.013(1)).

This section reports what statutes, rules, agency documents and court opinions say, as we read them on November 8, 2026. It is not legal advice. How any of it applies to a school depends on the facts, and a lawyer is the right person to answer that.

The statute does not say directly that martial arts instruction is a program of physical exercise, though an exemption for it suggests the Legislature thought it could be. Its definitions do not define physical exercise equipment, so the text does not settle whether bags, mats or strength gear count. We did not read the department's site, which disallows all automated agents, so we have no count of exempt schools.

For a business that is a health studio, the statute sets an annual registration fee of $300 per location (s. 501.015) and a surety bond of $25,000 per location (s. 501.016(1)), with exceptions. One exception bears on schools that bill by the month: a studio collecting direct payment on a monthly basis, with any service fee reasonable and fair, is exempt from the bond (s. 501.016(5)).

Contracts for future services must allow penalty-free cancellation within 3 days, not counting holidays and weekends (s. 501.017(1)(a)). An initial contract may not exceed 36 months (s. 501.017(1)(e)). A studio may not represent a contract as being for a lifetime or a perpetual membership (s. 501.017(5)), which matters to a lifetime membership offer only if the school is a covered health studio. Section 501.019 ties violations to the Class II penalty category, and section 570.971 caps a Class II fine at $5,000 per violation (s. 570.971).

Automatic renewal sits in a separate statute. Section 501.165 covers a provision that renews a service contract for more than 1 month when the renewal keeps it in effect past six months (s. 501.165(1)(a)). It requires a seller to let a consumer cancel in the same manner and by the same means as the consumer accepted (s. 501.165(2)(d)). The renewal subsection lists a health studio as defined in section 501.0125 among the sellers it does not apply to (s. 501.165(2)(e)). The text does not say whether a school exempted under section 501.013 remains a health studio for that purpose.

Does Florida's combat sports law reach karate or judo schools?

Not for traditional martial arts, but yes for mixed martial arts: chapter 548 of the 2026 Florida Statutes exempts a professional or amateur martial arts activity, naming karate, aikido, judo and kung fu, and says the term does not include mixed martial arts (s. 548.007(6)). The chapter is administered by the Florida Athletic Commission (s. 548.002), which has jurisdiction over boxing, kickboxing and mixed martial arts matches involving a professional and approves amateur sanctioning organizations for those sports. As we read the chapter, a karate school's belt test or point tournament is not what it regulates, and an amateur mixed martial arts bout is within it.

Does a kids' karate program need a Florida child care license?

A school-age class that meets the conditions does not: Florida's school-age child care rule, in the version effective 4/9/2026 (Florida Administrative Code), names a karate class as an example of a single-purpose instructional program exempt from licensing (Rule 65C-22.008(3)(b)). That exemption comes from the Department of Children and Families' rule, not the statute. Section 402.302 defines child care as the care, protection, and supervision of a child on a regular basis for a fee (s. 402.302(1)) and reaches arrangements serving more than five children unrelated to the operator (s. 402.302(2)). Its list of exclusions names schools, residential summer camps, summer day camps, Bible schools and transient lodging operators, and does not name martial arts.

The exemption has conditions. The program must comply with the minimum background screening requirements in sections 402.305 and 402.3055 (Rule 65C-22.008(3)), and exempt providers must file an attestation about it. Instruction must be the program's only service, and session time may not exceed two hours (Rule 65C-22.008(3)(b)3); the current version states that cap per child per day. The program may not serve meals, though pre-packaged snacks and drinks are allowed. It may not advertise or otherwise represent that it has attributes of child care (Rule 65C-22.008(3)(b)2). As we read that condition, a program marketed as after-school care, in a video or anywhere else, could fall outside it; the Department decides exemption requests.

The rule links above go to Cornell's Legal Information Institute, which reprints the version before the 2026 amendment. We also read the current text in the Word file on the state's rule site, and these paragraphs match apart from the per-child wording noted above.

Do Florida's youth coach screening rules reach martial arts teams?

They apply to teams, and the statute does not mention martial arts: since July 1, 2026 (s. 943.0438(2)(a)), section 943.0438 has required a private entity that organizes a youth athletic team to conduct a level 2 background screening of each current and prospective athletic coach (s. 943.0438(2)(a)2). Level 2 screening includes fingerprinting for state and national criminal history checks. The statute defines a team as a group of players assembled to form one side in a competitive game or sport that primarily practices and competes in Florida (s. 943.0438(1)(c)). A school's regular classes do not obviously fit that wording. Whether a school's competition team does depends on facts the statute does not address.

How do other states treat martial arts school contracts?

States take at least three approaches, as we read their texts on November 8, 2026. Iowa's physical exercise club law names establishments teaching judo, karate, or kung fu (Iowa Code 552.1). New Hampshire has a chapter of its own for martial arts schools, which it defines as establishments teaching forms of self-defense such as judo or karate (RSA 358-S:1). A Tennessee Attorney General opinion dated November 6, 2015 (Op. 15-74) lists an organization teaching a form of martial arts such as judo or karate as an exception to that state's health club definition (Op. 15-74). Florida sits between them, with an exemption a school claims by affidavit.

We read Tennessee's exception only through the opinion. We did not read Ohio's or Washington's codes, because their official code sites bar automated agents, so those states are not in the table.

What do federal rules say about videos of students under 13?

The federal COPPA Rule, as displayed on November 8, 2026, defines a child as an individual under the age of 13 (16 CFR 312.2), and its definition of personal information includes a photograph, video, or audio file that contains a child's image or voice (16 CFR 312.2). The FTC's amended rule took effect June 23, 2025 (90 FR 16918), and regulated entities had until April 22, 2026 to comply, apart from certain safe harbor provisions (90 FR 16918).

COPPA reaches operators of commercial websites and online services that are directed to children or have actual knowledge of collecting from a child. Whether a school posting class clips is such an operator depends on the facts. Our kids video statistics page covers the rule in more detail.

Florida's likeness statute is a separate rule. Section 540.08 requires consent to use a person's name or likeness for a commercial or advertising purpose, and says that for a minor it comes from the guardian or either parent (s. 540.08(6)). Our dance studio video statistics page reports the rest of that statute.

What do FTC rules say about testimonials, reviews and bought followers?

The FTC's Endorsement Guides, published July 26, 2023 (16 CFR Part 255), say a material connection that must be disclosed can include free or discounted products, whether or not an endorsement is required in return (16 CFR 255.5). When an endorsement uses both picture and sound, as a video does, they say the disclosure should be made in the visual and audible portions (16 CFR 255.0(f)). If an advertiser lacks substantiation that an endorser's experience is what consumers will generally achieve, the ad should disclose the generally expected performance (16 CFR 255.2(b)). A testimonial about a student's results is the kind of endorsement those words address. The Guides are the FTC's interpretation of the law, not binding rules.

The FTC's separate rule on consumer reviews and testimonials took effect October 21, 2024 (89 FR 68077). It makes it a violation for a business to write, create, or sell a review or testimonial that materially misrepresents the reviewer or the experience (16 CFR 465.2), and to give incentives conditioned on reviews expressing a particular sentiment (16 CFR 465.4). It also bars buying fake indicators of social media influence, a term that includes followers and views, when the buyer knew or should have known they were fake and they misrepresent influence for a commercial purpose (16 CFR 465.8). The FTC's notice says the rule lets courts impose civil penalties (89 FR 68077), and the agency's penalty rule lists $53,088 as the maximum amount under that section of the FTC Act (16 CFR 1.98).

Is the FTC's click-to-cancel rule in force?

No: in an opinion filed July 8, 2025 (Custom Communications v. FTC), the U.S. Court of Appeals for the Eighth Circuit wrote “we grant the petitions for review and vacate the Rule” (opinion), citing the FTC's failure to follow a procedural requirement of the FTC Act. The FTC restored the earlier form of its Negative Option Rule effective February 12, 2026 (91 FR 6507). It took comments on a new advance notice until April 13, 2026 (91 FR 12318). A Federal Register search for FTC negative option documents on November 8, 2026 showed no proposed rule text after that notice. Florida's automatic renewal statute, described above, is unaffected by the vacatur.

What does the Safe Sport Act require, and how many reports does the Center receive?

The Protecting Young Victims from Sexual Abuse and Safe Sport Authorization Act of 2017 became law on February 14, 2018 (Public Law 115-126), and it requires a covered individual to report suspected child abuse as soon as possible, defined as within a 24-hour period (Public Law 115-126). We read the Act as enrolled and did not trace later amendments to the codified sections.

A covered individual is an adult authorized by a national governing body, a member of one, or an amateur sports organization that participates in interstate or international amateur athletic competition to interact with a minor or amateur athlete (Public Law 115-126). The Act does not mention martial arts schools, so whether one is covered turns on that definition. It also requires applicable amateur sports organizations to limit one-on-one interactions between a minor and an adult who is not the minor's guardian unless they are within observable and interruptible distance of another adult, except in emergencies (36 U.S.C. 220530).

The U.S. Center for SafeSport counts 9,683 reports received in 2025 across all sports in its jurisdiction (2025 Annual Report), up 19.6% from 2024 (2025 Annual Report). Its outcome table as of December 31, 2025 lists 3,322 cases with a violation outcome (2025 Annual Report) among 32,035 cases in all (2025 Annual Report), a total that includes matters closed for lack of jurisdiction. The report gives no martial arts or per-sport breakdown, so these figures describe the whole Olympic and Paralympic movement. We report counts only and name no one.

Can a kata or form be copyrighted?

The Copyright Office has not addressed it by name: chapter 800 of its Compendium, dated 01/28/2021 (Compendium), does not use the words martial arts, karate, judo or kata, and it lists exercise routines, aerobic dances and yoga positions as non-expressive movements it cannot register (Compendium 806.5(B)). It says the same of athletic activities or competitive maneuvers as such (Compendium 806.5(B)).

Circular 52, revised in October 2022, says feats of physical skill or dexterity are not eligible for registration as choreography (Circular 52). Its list of things not registrable ends with “A compilation of any of the above types of movements” (Circular 52). As we read these documents, a kata presented as a sequence of fighting techniques would meet those limits, and a form composed and staged as a performance for an audience is the closer question. Neither document decides it.

The recording is a separate matter. The Compendium says making an unauthorized reproduction of a video of an athletic competition may infringe the audiovisual expression in that recording, even though the movements themselves are not protected (Compendium 805.8(D)). A school's own class video can be protected as a video whether or not the form in it can be. Our dance studio video statistics page covers choreography cases.

What does copyright law say about music in classes and class videos?

The Copyright Act's face-to-face teaching exemption is limited to instructors and pupils at a nonprofit educational institution (17 U.S.C. 110(1)), so a for-profit martial arts school is outside its words. Section 110(5)(B) exempts some radio and television communications, on conditions, in an establishment other than a food service or drinking establishment with less than 2,000 gross square feet (17 U.S.C. 110(5)(B)). By its text that exemption is limited to broadcast stations and cable or satellite carriers, so it does not describe a recording or a streaming service played in class.

Statutory damages run up to $30,000 per work (17 U.S.C. 504(c)(1)) and up to $150,000 per work for willful infringement (17 U.S.C. 504(c)(2)). Our dance studio page reports what performing rights license forms do and do not cover, including ASCAP's statement that it does not license putting a song in a video.

What do the popular martial arts numbers really say?

The martial arts figures repeated most often trace to a Los Angeles police review of arrests in 1988, a paid market report, a survey we could not open and one video vendor’s blog. We found no study that prints a percentage gain in grades. Each entry below gives the claim, where it came from, what the origin measured and what to use instead. “Earliest” here always means the earliest we found.

“90% (or 95%) of fights go to the ground”

The figure traces to a Los Angeles Police Department review of arrests made in 1988, in which 62% of altercations ended with the officer and subject on the ground, not to any count of street fights (Leblanc, Journal of Non-lethal Combatives, 2007). The review’s findings survive in Chris Leblanc’s 2007 journal article, which quotes directly from a pamphlet for a July 1997 LAPD training seminar (Leblanc). Leblanc writes that LAPD Sergeant Greg Dossey completed the comparison in 1991 (Leblanc) and that LAPD’s Training Review committee replicated it in 1992 (Leblanc). We could not find the original study or the pamphlet, so every LAPD figure from 1988 below is as quoted in that article.

The review counted 316,525 LAPD arrests in 1988 (Leblanc). Of those, 5,617 required a use of force report (Leblanc), and 2,031, or 0.6% of arrests, met its test for an altercation (Leblanc). The 62% is the share of those altercations that ended with the officer applying a joint lock and handcuffing the subject on the ground. A second number, 95%, is the share of altercations that fell into five patterns of behavior (Leblanc), and it is not a share that went to the ground.

Leblanc writes that the popularizing of the statistic is most often laid on the Gracie family, and that he had not seen a martial arts source cite the study accurately (Leblanc). The Gracie family pages we could read do not print a percentage. A November 1994 interview reprinted on gracie.com quotes Carley Gracie: “While it’s true that most fights wind up on the ground, they don’t have to” (gracie.com, archived). A December 1997 interview on the same site has him saying “most fights come to a clinch and go to the ground” (gracie.com, archived). In the early archived pages of gracie.com and gracieacademy.com that we sampled, none prints a percentage for fights on the ground or cites the LAPD.

The earliest printed percentages we found date from 1996. A 1996 book, The Warrior Within, quotes the proposition that 90 percent of all street fights end up on the ground (Internet Archive full-text search result). In 1997 Paladin Press’s 1001 Street Fighting Secrets printed that approximately 90 percent of all street fights go to the ground (Internet Archive full-text search result), and a mail-order catalog sold ground-fighting instruction on the line that the ground is where 90% of all street fights end up (Internet Archive full-text search result). A 2003 book, Grappling Masters, printed the larger form, 95 percent of all fights (Internet Archive full-text search result), and in June 2004 Grappling magazine stated 90 percent as a passing fact (Internet Archive full-text search result). We searched the Internet Archive’s full text and the web for these wordings; Google Books was out of quota and could not be searched. Leblanc’s own conclusion is that the LAPD study does not show that 90% of fights go to the ground (Leblanc).

Other police measures are different kinds of number. A 2003 Calibre Press and PPCT survey of about 1,400 cases from officers at training seminars found 52% of respondents had faced an attacker trying to force them down, and 60% of those said the attacker succeeded (Leblanc). LAPD’s own 2022 review counted 724 takedowns or leg sweeps, present in 32% of 2,230 non-categorical use of force incidents, in a year with 43,626 arrests (LAPD). That counts a force option an officer used, not where an encounter ended. None of these sources counts fights between civilians.

Use instead: “In an LAPD review of 1988, as quoted in a 2007 journal article, 62% of the 2,031 altercations arising from 316,525 arrests ended with the officer and subject on the ground.” Do not present it as a share of fights, and do not print the larger forms.

“Martial arts improves children’s focus and grades by X%”

We found no study that prints a percentage gain in school grades from martial arts training. The one figure we could read is on a school’s own page: Team Tooke Mixed Martial Arts Academy in Houston says a University of Vermont study showed success in improving grades by 2.5%, with no journal, author or year (Team Tooke). Our searches for that study returned only the school’s page.

The study gyms do cite did not measure grades. Lakes and Hoyt, writing in the Journal of Applied Developmental Psychology in 2004, randomly assigned 207 children, kindergarten through Grade 5, by homeroom class to school-based Tae Kwon Do or traditional physical education (ERIC abstract). After a 3-month program, the martial arts group improved more than the comparison group on cognitive and affective self-regulation, prosocial behavior, classroom conduct and performance on a mental math test (ERIC abstract). The abstract lists no school grades. It reports a Group by Gender interaction on cognitive self-regulation and classroom conduct, with boys showing greater improvements than girls (ERIC abstract). We read the abstract, because the publisher’s site bars automated readers. Assignment was by homeroom class rather than by child.

Repeats change the terms. KD MMA, a Glendale gym that sells classes, tells readers the same study ran for a school year (KD MMA), against the abstract’s 3-month period. One later trial in the evidence section of this report did measure academic achievement and reported a small standardized effect of 0.16, not a percentage gain.

Use instead: “In a randomized study of 207 children in kindergarten through Grade 5 (Lakes and Hoyt, 2004), children in a 3-month school Tae Kwon Do program improved more than children in physical education on measures of self-regulation, conduct and a mental math test.” Do not give a percentage and do not say the program raised grades.

“The U.S. martial arts industry is worth $X billion”

The current figures come from IBISWorld, a firm that sells industry reports, and they differ across its own free pages. Its industry page states $21.0bn for 2026 (IBISWorld); its market-size page states $21.2bn for 2026 (IBISWorld); and its summary text says revenue reached $21.0 billion in 2025 (IBISWorld). The market-size page’s headline sentence prints $xx.xx in place of a figure for free readers (IBISWorld). Business counts differ the same way, 72,029 on one page (IBISWorld) and 76,364 on another (IBISWorld), and it states 132,246 people employed (IBISWorld). The free pages do not describe how any of these were produced.

IBISWorld sells the full report, last published in January 2026 (IBISWorld). Its code, OD4187, is its own, though the page labels it a NAICS code (IBISWorld). Its definition excludes self-defense or boxing instruction (IBISWorld) and, by its own description, many of these studios operate as nonemployers.

Federal figures measure something else. The 2022 Economic Census counted $11.64 billion in revenue and 20,627 establishments with paid employees for all sports and recreation instruction, NAICS 611620, which is shared with swim, gymnastics, golf and other instruction and has no martial arts split. The Census figure covers only employers, while IBISWorld says many studios have none, so the two cannot be compared directly. Even so, IBISWorld’s 2026 figure for one discipline is larger than the 2022 Census revenue total for every kind of sports and recreation instruction with employees. We report the conflict and do not resolve it.

Software sellers repeat whichever number is nearest. Gymdesk printed $21.2 billion crediting IBISWorld (Gymdesk, which sells gym software). WodGuru wrote that the industry was valued at $8.16 billion in 2020 (WodGuru, which sells gym software), and Glofox that it grew to an estimated $10 billion by 2023 (Glofox, which sells gym software).

Use instead: IBISWorld’s figures labelled as IBISWorld’s estimate for its own industry definition, with the year, or the Census figures labelled as all sports and recreation instruction. Do not print one number as “the industry.”

“18 million Americans train in martial arts”

The figure is older than the blogs that print it, and we could not read its original. The earliest appearance we found is a 6 May 2003 forum post on MartialTalk quoting a paid article, which said 18.1 million Americans participated in some sort of martial art at least once in the past year (MartialTalk). Later pages credit Simmons Market Research, a New York City firm (USAdojo), but we could not open the article or a Simmons release.

Later pages moved the date and dropped the scope. USAdojo.com repeated 18.1 million on September 6, 2011 (USAdojo), and Fight Times called it “a recent study” in October 2011 (18.1 million) (Fight Times). Glofox, which sells gym software, dated the same figure to 2010-2011 in a post captured in 2019 (Glofox, archived), although the same numbers were circulating in 2003. Its later post said around 18 million Americans at least once a year (Glofox). WodGuru wrote in 2025 that 18 million participate annually, crediting Glofox (WodGuru). Wellyx wrote in May 2026 that approximately 18 million do, crediting Glofox and WodGuru and calling that consistent with a Statista estimate of 3.9 million actively engaged participants (Wellyx, which sells gym software).

Use instead: SFIA’s count, in the participation section of this report, labelled as SFIA’s with its survey year: SEC filings citing SFIA’s reports give more than 11.8 million people in martial arts and combat sports disciplines in 2023. SFIA sells to the sports industry. Do not print 18 million as a current count.

“70 million (or 80 million) people practise taekwondo”

These are estimates, and World Taekwondo’s own president has said no one has the exact number. Chungwon Choue told Around the Rings: “Nobody knows the exact number of practicing taekwondo athletes, but we are counting 60 or 70 million” (Around the Rings, via Infobae). The article’s page is dated 2021, but its text treats the 2013 IOC Session as ahead.

The figure has not moved in a clean line. Guinness World Records, in an entry dated 20 June 2012, says some 50 million people practise it, crediting a British branch of the federation (Guinness World Records). The higher form circulates without a named count: MiTaekwondo, a taekwondo website, says approximately 80 million people train globally “according to various martial arts organizations and reports” (MiTaekwondo).

We could not read what World Taekwondo’s site says today: its robots file tells automated readers to stay out, and we respected that, including for Internet Archive copies.

Use instead: quote the federation as giving an estimate, with the speaker and the year, as in Choue’s 60 or 70 million. Do not print any of these as a membership count.

“Video on a landing page lifts conversions by 80%”

The figure is a best case from one video vendor, EyeView, in 2009-2010, about financial and tutoring websites, not martial arts schools. The earliest EyeView post we found reported that eToro visitors who watched its video were 20% more likely to download the product (December 2008) (EyeView, archived). In February 2009 it said UMOO viewers were 80% more likely to become depositing users, comparing viewers with non-viewers for one client (EyeView, archived), and in November 2009 it quoted a TutorVista manager on a first test that lifted conversion by over 80 percent (EyeView, archived). Its 2010 white paper said only that “in some cases” the boost was over 80% (EyeView white paper, archived), and the one test it described, the eToro split test, was now almost 32 percent (EyeView white paper, archived).

The scope fell away in repeats. By August 2010 Unbounce, a landing-page software seller, wrote that video on landing pages can increase conversion by 80% (Unbounce, archived), and WordStream, a pay-per-click software seller, repeated 80% in March 2016, crediting “EyeWideDigital” (WordStream). We searched martial arts school marketing pages and Spark Membership’s landing-page guide for the figure and found no martial arts test or repeater behind it.

The larger later evidence points the other way. Unbounce’s own 2021 analysis of about 35,000 customer landing pages in each of three periods (Unbounce) concluded that video appears to have a minimal or negative impact on landing-page performance regardless of the conversion goal (Unbounce). Its April 2025 article of landing-page examples still says landing pages with video can increase conversions by 80%, linking back to its own 2010 article (Unbounce). Use instead: do not cite a conversion lift for martial arts school video; say Unbounce’s 2021 study of 35,000 pages found video had a minimal or negative effect, and judge a school’s video by its own trial-class bookings.

Every popular claim our research pages trace, 853 in all, is on one page: popular video statistics, fact-checked.

How we built this page

We started from the questions people search for about martial arts school video statistics and looked for the organization that actually produced each answer. Every figure on this page sits in an evidence ledger with its source, the exact table or paragraph it came from, the measurement period, the population measured, and the date we checked it. This edition holds 637 figures from 115 publishers.

On November 8, 2026, each sourced figure on this page was re-fetched with the fetch cache cleared and matched against the recorded wording: BLS occupation wage estimates and the Quarterly Census of Employment and Wages (through the BLS data API and data files) and Employment Projections pages (through Internet Archive copies, because bls.gov refuses automated requests); Census County Business Patterns, Nonemployer Statistics, the 2022 Economic Census and the Annual Integrated Economic Survey (through the Census data API) and the 2022 NAICS Manual; CPSC NEISS case files and Data Highlights (through Internet Archive copies, because cpsc.gov refuses automated requests); IRS Form 990 text through ProPublica’s Nonprofit Explorer; NFHS participation reports; SFIA and Physical Activity Council pages; SEC filings on EDGAR; the Florida Statutes, Florida Administrative Code, eCFR, the Federal Register, govinfo.gov, U.S. Copyright Office documents and other states’ codes; YouTube’s own help and transparency pages; seller, association and curriculum pages; and journal abstracts (PubMed and PubMed Central rows re-read through NCBI’s E-utilities, because those pages answer scripts with a bot check). Our YouTube figures come from the YouTube Data API, our filing counts from EDGAR full-text search and our injury sums from CPSC’s published NEISS case files. We left out franchise disclosure documents, because Minnesota’s CARDS database refused our automated requests on the day we collected this data, so this edition has no franchisor outlet, investment or earnings figures. We left out hosts whose robots rules bar AI agents, among them TikTok, Instagram, Facebook, USA Taekwondo’s and USA Judo’s own sites, Team USA, the AAU, World Taekwondo, FloGrappling, Statista and the publishers of several journals (for those we use only the PubMed abstract), and ftc.gov pages (they answer scripts with an error page, so FTC rules are cited from eCFR and the Federal Register). Seller surveys with no sample size or field dates are not used.

We only cite the producer: government agencies, regulators, company filings and official posts, and the survey owner's own report. We do not cite statistics roundups, Statista-style aggregators, or salary sites without a public method. We did not bypass paywalls or sign-up forms; where a full report was gated, we used only the figures its publisher states publicly.

Figures marked "our calculation" are arithmetic on the cited numbers, and anyone can reproduce them:

This edition contains no Mark Studios customer data.

Limitations

• No federal series counts martial arts schools or instructors alone. BLS and Census count all sports and recreation instruction (NAICS 611620), which puts martial arts schools with swim, gymnastics, golf and other instruction, and instructors with no payroll are not in those counts. BLS has no occupation code for martial arts instructors: they can fall under coaches and scouts or self-enrichment teachers, both shared with many other fields. The 2022 Economic Census has no martial arts line.
• Our YouTube read follows YouTube’s ranking and leans on a few channels. The 408 videos are what YouTube’s search returned on November 8, 2026 for ‘karate class’ and ‘taekwondo for kids’ (top 200 each) and ‘BJJ for beginners’ (top 50, because the daily search limit ran out), sorted by views with no country filter. It is not a census of martial arts video. View counts are lifetime snapshots, and we sorted 262 channels by hand from their public text without checking credentials. Two channels carry much of the result, and we print the shares with them set aside. Family uploads and any video or channel that names a child appear only as a class and counts.
• National participation is poorly documented in public. SFIA does not publish its martial arts line on a free page. The figure we print comes second-hand from a seller’s SEC filings and combines two SFIA reports. Governing-body memberships are the bodies’ own approximate counts and leave out most people who train at a local school.
• Injury figures are estimates of hospital visits. They count emergency-department treatment only, carry no standard errors on our own sums, and cannot give a rate per student because NEISS has no count of people training. CPSC’s hospital sample changed between 2023 and 2024. We could not read a 2025 file.
• Study results come from specific settings. Most video-learning experiments are small, use novices or students and compare video with other video rather than with a live teacher. We found no study scoring the quality of martial arts videos on YouTube or TikTok, and none testing recorded video against an instructor in a martial arts school. Children’s trials differ in design, and several report no effect.
• Seller and survey-owner figures are their own. SFIA, Gymdesk, Spark Membership, Zen Planner, Kicksite, Mindbody, Gold BJJ, Gracie University, BJJ Fanatics and IBISWorld all sell into this market, and IBISWorld’s method is not on its free pages. Each is labelled where it appears.
• This edition has no franchise figures. The Minnesota filing database refused our automated requests, so Item 20 outlets, Item 7 investment ranges and Item 19 earnings are not here.
• Origin traces rest on what we could read. The LAPD figures from 1988 survive only as quoted in a 2007 article. Book and magazine wordings come from the Internet Archive’s full-text search, with years from its item records, and Google Books was out of quota. Every “earliest” means the earliest we found.
• Rules are summaries, not legal advice, dated to the versions we read in November 2026. How a statute or rule applies to a school depends on the facts.
