No Medical Files, No Medals: the Injury-Data Gap in Vietnamese Martial Arts

The second round was 47 seconds old. A 21-year-old sanshou fighter on Vietnam’s national wushu team stepped out of his corner, threw a right roundhouse kick — with the very leg he had complained about for three weeks before the tournament — and his knee buckled at an angle nobody in the arena wanted to see. The referee stopped the bout. The corner had an ice bag, an elastic bandage and a bottle of mineral water. There was no medical file. No pre-competition screening. Not one line recording that he had cut 5.8 kg in 71 hours to make weight.

Three weeks later I asked his coach one question: “Where is the MRI scan?” He went quiet for a few seconds and said: “The team cannot afford one.” Ligaments rarely lie. The people who hide them always do.

Vietnamese martial arts are framed wrongly in every statistical table. Under one federation, taolu — forms, no contact, constant landings — sits beside sanshou, full-contact fighting, and both are then lumped in with boxing, Muay, Vovinam and karate. These four groups carry four different injury profiles, yet they usually share one doctor, one ice bag and one ambulance ride.

SEA Games 31, held in Hanoi in May 2026, was the edition with the largest number of martial arts events Vietnam has ever hosted, and the host delegation finished top of the overall medal table. That same year, Lion Championship launched as Vietnam’s first professional MMA promotion. Those two events pushed the number of regularly competing fighters up very fast. The number of sports physicians who understand martial arts has barely moved.

I have watched domestic martial arts events since my years as a trainee reporter, and my way of reading a bout does not start with the score. It starts with how many minutes the fighter has banked, and where the pain has lasted longest. In 2026 I wrote about 18-year-old striker Nguyen Gia Huy of Sai Gon FC: 23 consecutive matches, 1,847 minutes, a knee complaint ignored for six weeks, then a torn anterior cruciate ligament and nine months out. The day that analysis ran, more than a few people called it a verdict handed down on a teenage player. Three years later, in the season frozen by COVID-19, I built a database of 342 players and 1,208 injury records across the V-League and Southeast Asian competitions. 1,208 records in a frozen season: the pain never froze.

That database contains not a single line about martial arts. That is my failure, and it is the failure of an entire system.

Reading a fighter’s physical load has to be split by discipline. A high-level men’s taolu routine lasting around 80 seconds can contain 60 to 80 landings, each loading the ankle and knee with three to five times body weight. Nobody collides with a taolu athlete, so nobody files the sport under risk. But an ankle does not distinguish causes: it only records how many times it was loaded.

Sanshou is the exact opposite. Three rounds of two minutes each, with throws and high kicks permitted. Injuries cluster at the knee joint, the ribs and the head. At national-team level, fighters have a doctor and a regular check-up schedule. At provincial level and in grassroots events, fighters have a coach who doubles as the medical staff, and a belief that pain is something you simply endure.

An amateur fighter at provincial level may compete in 9 to 12 bouts a year, on top of military training and a day job. Most of their competitive life passes without a single cardiac screening and without any neurological test after a knockout loss.

The most alarming point is not on the mat. It is on the scale. Most domestic events still weigh athletes in on the morning of competition, leaving a fighter only a few hours to rehydrate. Drops of 5 to 7 percent of body mass inside 72 hours recur far too often in my records. Reduced plasma volume cuts endurance in the final round, and in sports with head contact it raises concussion risk. One mechanism, two different consequences.

In those 1,208 older records, groin injuries rose 32 percent in the first two rounds after Tet, when more than 210 players had averaged only three sessions across a 24-day break and were then asked to play a full 90 minutes. Fighters take ten days off for Tet, gain a few kilos, then have to cut weight and enter a tournament in January. The mechanism is identical; only the sport changes.

The most comfortable explanation is to blame “mental steel”. I do not buy it. I think coaches and fighters are responding rationally to a system with the wrong incentives. A national-tournament slot is income, a quota, next year’s contract. Admitting knee pain means handing that slot to the man behind you. When the reward is entirely concentrated on showing up, silence becomes the sensible choice.

The second contrarian angle sits inside the label itself. Many people place taolu outside combat martial arts and conclude that taolu athletes do not need sports medicine. The result is that the group with the densest landing load receives the least recovery support. A form practised two hundred times a week damages an ankle no differently from a fight.

And the assumption that MMA is the most dangerous discipline deserves to be challenged. In my records, accumulated risk scales with calendar density and with the size of the weight cut, not with the maximum force of a single strike. An amateur boxer fighting four tournaments in ten weeks, cutting weight sharply each time, is carrying more risk than a professional MMA fighter competing twice a year with supervised nutrition.

What needs doing is not expensive. One shared electronic medical record across the martial arts federations; mandatory pre-season screening; earlier weigh-ins so fighters have time to rehydrate; and one physiotherapist per provincial team. Those four items cost less than a gold medal.

As long as a 21-year-old fighter still has to hear the words “the team cannot afford an MRI”, every medal table remains only half the story. The other half sits in a ledger nobody opens.
