Vietnamese Martial Arts Is Missing a Medical Record

Two minutes into the second round, the young fighter from the host delegation took a full kick to the right side of his ribs. He dropped to one knee, pressed his palm against his rib cage, and breathed through his nose. The referee stopped the bout. His corner pulled him outside, rubbed liniment on the area, re-wrapped the tape, and pushed him back onto the mat within forty seconds. The crowd applauded. He won on points.

I was sitting in the sixth row, notebook open, and I managed exactly three lines. Second minute of the second round. The mechanism was a right-leg kick to the flank. Time spent handling him outside the ring was forty seconds.

Those three lines were the entire medical file for that injury. No imaging, no diagnosis, no follow-up date. Nobody asked him where precisely it hurt, what kind of pain it was, or how long the pain lasted after the final bell.

That night I went back to my hotel room and tried to trace it backwards. There was nothing to trace. Not a single result sheet, not a single medical report, not one line about the injury I had just watched with my own eyes.

That is why this piece exists.

Most of the injury data in Vietnamese martial arts lives inside the memory of whoever happened to be watching, and memories cannot be added together.

Over the past decade, Vietnamese martial arts have travelled a long road. Vovinam has a place in the SEA Games programme, with a standardised belt system and combat events. Vietnamese boxing has continental medals in both men's and women's weight classes. Muay Thai has Nguyen Tran Duy Nhat, a fighter who tied his name to multiple WBC Muay Thai titles in the region. Domestic MMA events now run more regularly, with contracts, television coverage, and spectators who pay to sit and watch.

Running parallel to that road is a blank space few people mention: there is no injury surveillance system that is maintained continuously, published openly, and open to cross-checking. In football, I can trace back the return date of a player, the minutes he played after returning, the number of re-injuries. In martial arts, I have no launchpad for that. Everything stops at the level of anecdote.

In 2026, when I was a second-year student, I began taking notes on defender Do Duy Manh, who was hurt in the sixty-seventh minute of a continental cup final yet played to the end of the match. I logged that entire season, then expanded it into forty-eight pages of data on injuries in a European top-flight league. From that file I drew a lesson that has followed me through my career: the most dangerous part of a sports injury is not the moment it happens, but the period afterwards, when nobody defines clearly what healed actually means.

Why is there no data? Because nobody is responsible for collecting it. At most domestic combat sports events, the on-site medical staff do the work of event medicine: first aid, stopping bleeding, managing concussion, signing the paper that lets a fighter continue. That is firefighting. Longitudinal follow-up is a different job, and it requires someone who stays behind after the arena lights go out and types each line into a fixed file. Nobody pays that person, so nobody does it.

The first task is almost embarrassingly simple: agree on a definition. An injury should only be counted when a fighter misses at least one training session or one bout because of it. Without a shared definition, two people sitting at the same event will count two different totals, and both can justify their own number.

Alongside that definition sits the denominator. Ten injuries per one thousand hours of training is entirely different from ten injuries per one hundred hours of training. An injury rate only means something when it is tied to exposure hours, and exposure hours are almost never recorded in Vietnam. In 2026, I followed eight months of rehabilitation for a young player from an academy in Da Nang who tore his anterior cruciate ligament in the twenty-third minute of a match on the twelfth of March. I counted every swimming session, every set of dumbbell work, every measurement of knee range of motion. When I cross-checked the numbers, I reached the conclusion that the recurrence rate in Vietnam's top league was roughly twenty-three percent higher than in Japan's. But I had to tell myself that the figure carried a crack: the two leagues define recurrence differently. I had placed two things on the same table that were not fully comparable.

If I had to pick the single most dangerous blank space, I would pick weight cutting. At many domestic events, weigh-ins happen close to fight time, sometimes on the same day. Fighters make weight by running in plastic suits, taking hot baths, and drinking almost nothing in the final twenty-four hours. This is not against the rules, and that is precisely the problem: the rules do not forbid it, so nobody protects them. Losing five percent of body mass in a short window increases the force of impacts to the head, reduces reaction speed, lowers the ability to absorb strikes, and raises the risk of kidney damage. Urine testing to detect dehydration, a cheap device plus a single sheet of results, is essentially absent from the weigh-in protocol at most amateur events.

Then comes concussion, and here the silence is systemic. After a punch or a knee to the head, a fighter goes down, stands up, and if the referee waves the bout on, it continues. The concussion assessment tools used internationally in combat sports require a pre-season screening, a baseline test, and a multi-step protocol before an athlete is allowed to take strikes again. Those three elements do not coexist inside one event system in Vietnam. The only thing that exists is the subjective feeling of the person who just got hit, in a setting where saying "I feel fine" is the only route to staying in the fight.

Returning from joint injuries is the next blank space. Anterior cruciate ligament tears, severe ankle sprains, shoulder dislocations: these injuries have clear return criteria in developed sporting nations, covering range of motion, side-to-side strength symmetry, jump tests, reaction speed, and a psychological readiness component. Those criteria protect fighters from themselves and from pressure coming from the people around them. During the eight-month rehabilitation case I followed in 2026, I noticed something worth saying out loud: the player recovered well, but at no point was his status confirmed by a standardised test. He came back when his treating doctor allowed it, and that was good. But the allowance rested on one person's judgement, not on a set of thresholds somebody else could verify.

There is one more blank space that no spreadsheet ever touches: the invisible injury. In 2026, I spent three weeks rereading the injury histories of national teams preparing for a World Cup and found that one major side had seven players who had suffered serious injuries within the twenty-four months before the tournament. That group performed noticeably worse in situations requiring maximal speed. The finding was disputed, and I understand why. But the intensity of the reaction taught me something extra: people accept that tendons and ligaments can tear, while the psychological side is expected to be endured alone. The 2026 World Cup taught me this: the biggest wound is the wound nobody sees.

So what does a minimum viable medical record require? One page per case, ten fields. Fighter's name, date, injury mechanism, location, tissue type, days of training lost, days of competition lost, follow-up date, return decision, and the name of the person who made that decision. Plus a separate file logging training hours and bouts for every fighter across the season. The cost is close to zero. It does not require an imaging machine, a new medical centre, or a foreign expert. It requires one person willing to stay behind after the arena lights go out.

The data framework here is empty not because equipment is missing, but because nobody has decided that counting is part of the job.

When there is no data, the cheapest conclusion always wins, and the cheapest conclusion always aims at the individual. The fighter hid his injury. The coach pushed his student too hard. An iron will turned into a will to endure. Those sentences sound reasonable, and they are convenient enough that they never get tested. But if nobody knows how many hours a fighter trained, how many bouts he fought, how many times he cut weight in a season, then nobody has the standing to declare him fragile or durable. Without a denominator, every judgement about an individual is a guess dressed up in a confident tone.

The second mistake, and in my view the more dangerous one over the long term, is importing protocols without calibrating them. A rehabilitation protocol built for a league with eight doctors, on-site imaging, and a three-week rest window will collapse at an event with one medic, no scanner, and a schedule of one bout every three days. The protocol is not wrong; it simply cannot survive here. What needs to happen before any protocol is imported is a measurement of the current baseline, so you know where you actually stand. To fix something, you first have to know where it is broken.

Every injury is a map, and I only learn to read it after getting lost.

People often assume the starting point of a sports medicine culture is a large centre full of expensive machines. In my view, the starting point is one sheet of paper. Within a single year, if every national championship across the combat sports recorded training hours, bout counts, and days lost to injury, Vietnam would have its first baseline dataset. In the following year, that dataset would be enough to set safe weight-cut thresholds and return-to-play criteria for each discipline.

Before asking why your fighter went down, ask who recorded the last time he went down.

Injury does not erase a fighter. It rewrites him, line by line of muscle and breath by breath. But to read that rewrite, someone has to be willing to write down the first line.
