Injuries in Vietnamese Martial Arts: 1,208 Records and the Stolen Weeks of Recovery

The doctor wrapped three loops of tape around his right wrist, the outermost loop pulled so tight that his little finger was turning pale. The 22-year-old fighter said the sentence I have heard in almost every locker room of every combat sport: "It hurts, but it's normal, brother." It was 10:40 pm, the night before weigh-in at a national championship. In my logbook, he had accumulated 14 sparring sessions across six weeks — 168 rounds, 42 of them involving direct contact to the head and hands. Not one ultrasound. Not one X-ray. I wrote on the last line: right wrist, pain localised in the anatomical snuffbox, suspected scaphoid fracture, no imaging performed.

Eleven days later, after he had made weight and lost in the quarter-finals, the hospital finally ran an MRI. The result: a fracture of the scaphoid in his right hand. Four months immobilised. His next season starts later than everyone in his age group, at 22 — the age at which a Vietnamese fighter either breaks through or gets left behind.

I am telling this small story because in Vietnamese martial arts, small stories like it are not recorded anywhere.

National teams in combat sports sit under different federations: boxing, vovinam, kickboxing, muay, and more recently the professional MMA organisations operating domestically. Training budgets follow medal quotas, on a four-year cycle built around three markers: the SEA Games, the Asian Games, the Olympics. SEA Games 31 was held in 2026 in Hanoi, with boxing contested in Bac Ninh; SEA Games 32 took place in 2026 in Phnom Penh; the 19th Asian Games in Hangzhou also fell in 2026; the Olympic qualifiers for Paris 2026 stretched across nearly two years and several continents. Between those markers sit the national championships, the clubs' cup, youth tournaments and the professional circuit.

The calendar thickened. The medical staff did not. A delegation might consist of 12 athletes, four coaches, one administrative officer — and a doctor, if it is lucky. That doctor is usually not a musculoskeletal specialist, has no handheld ultrasound, and has no power of veto over the decision to compete. At domestic events, most fighters tape themselves or rely on someone with expertise outside the team. From my experience covering bouts from national qualifiers to SEA Games finals, the number of fighters who have stepped into the ring with an undiagnosed injury is always larger than the number who have ever been inside a full rehabilitation protocol.

Which raises the question I have carried for years: if nobody records the pain, who is accountable when it becomes an injury?

The real load sits in the gym, not in the bout

A few years ago I assumed combat sports carried a lighter load than football. One fighter competes three times a year; one footballer plays forty matches. That reads correctly on a fixture list. It reads completely wrongly in contact minutes.

An amateur bout runs three rounds of three minutes: nine minutes of live contact. A sparring session at a national training centre typically runs eight to twelve rounds — 24 to 36 minutes of live contact. A fighter sparring three times a week across the eight weeks of a standard fight camp accumulates roughly 700 to 900 minutes of direct contact, the equivalent of more than 80 official bouts.

In combat sports, injury load is compressed into short windows. A fighter may compete only six times a year yet absorb contact volumes comparable to a footballer playing 40 matches — with one lethal difference: the footballer has 40 chances to spread the risk, the fighter has one.

Injury structures also differ sharply by discipline. Boxing loads the hand and wrist: the fifth metacarpal, the thumb, and above all the scaphoid — a small bone in the anatomical snuffbox notorious for poor healing because of its limited blood supply. Kickboxing and muay load the ankle, foot and ribcage through knee contact. Vovinam loads the Achilles tendon, the ankle and the lower back, through repeated kicks into hard targets and throws. MMA gathers all of it and adds grappling: neck, shoulder, knee meniscus.

Weight-cutting is an injury written in advance

In the amateur system, weigh-in happens in the morning and competition in the evening — roughly eight to ten hours to rehydrate. To make their division, fighters must typically shed four to six per cent of body mass in the final 72 hours, mostly by restricting fluids. Dehydration at that level reduces plasma volume, raises heart rate, impairs thermoregulation, disrupts electrolytes and lowers the threshold for head-impact injury. In professional MMA the figures can reach seven to ten per cent, but the athletes get 24 hours to rehydrate — still not enough, yet at least it exists.

In the records I collected, medical interventions on fight day cluster into two groups: severe cramping with dizziness in the opening round, and soft-tissue injury in the second bout of the same tournament — when the body has been through another weight cut without recovering.

Most serious injuries do not happen in the third round of the first fight. They happen in the first round of the second, in a body that has not rehydrated and a brain that has not reset.

1,208 records during a frozen season: pain never freezes

In 2026, when the entire competition system stopped, I spent two months building a database of 342 athletes and 1,208 injury records from the V-League and across Southeast Asia. COVID froze the pitches, but the medical rooms never took a break. Within that dataset sit 216 records from combat sports that I gathered later, drawn from internal reports, discharge papers and conversations with fighters, coaches and two doctors who had worked inside national delegations.

The first finding I kept unchanged because it holds in martial arts too: after long breaks — Tet, the off-season, lockdowns — soft-tissue injuries spike. Football data showed groin injuries rising 32 per cent in the first two rounds after Tet, when more than 210 players trained an average of three sessions across 24 days off and were then asked to play a full 90 minutes. Combat sports repeat that pattern in the groin, adductor and lower-back groups, roughly a third above the seasonal average.

Across the 216 combat records, injuries fall into five groups: 34 per cent hand and wrist; 21 per cent ankle and foot; 17 per cent knee, where ACL ruptures form a small share but carry the heaviest consequences; 12 per cent soft tissue of the ribcage and back; 9 per cent recorded concussion.

That last group deserves a caveat. Nine per cent is the figure for documented cases — with a person writing and a person signing. In combat sports, concussion is the quietest of all quiet injuries. For martial arts, the biggest error is not in the data we hold, it is in concussion — which multiplies itself when nobody writes it down.

In Vietnam there is no mandatory baseline neurological screening for fighters, no widely used Vietnamese-language version of a sports concussion assessment tool, and no minimum stand-down period after a knockout. In the records I read, the shortest gap between a knockout and the next bout was 20 days. International return-to-play guidance generally starts at 21 to 30 days and requires a graded progression — complete rest, light activity, progressive exertion, non-contact drills, controlled contact, then competition. That ladder needs time and needs a supervisor.

The stolen weeks of recovery

In 2026, as an intern, I wrote against the prevailing optimism around a famous forward: minimum recovery for his shoulder injury was 24 days, and he had only 19 before a major tournament opened. Nineteen days of recovery — a number that rewrote an entire transfer. I was called pessimistic that day, but the issue was never optimism. It was tissue biology.

The same principle applies in martial arts, only with far more severe breaches. A fighter with a scaphoid fracture needs three to six months of immobilisation depending on location and displacement; returning to bag work in week four means re-injury, and re-injury usually means surgery. An anterior cruciate ligament needs nine to twelve months to return to safe levels in a contact sport; returning in month six is planting a bomb in your own knee.

Ligaments rarely lie. The people who hide them always do.

The return-to-play criteria I use as a benchmark in my logbook are simple: no pain at maximal exertion; side-to-side strength difference under 10 per cent; neuromuscular control matching the healthy side; and completion of the full progression. What I have actually watched in gyms: pain gone, back on the ring.

The body is the quietest interrogation room on the fighting floor. No confession is spoken aloud, but every skipped step is written into another ledger — the one that, ten years later, reads as arthritis, degeneration, ruptured ligaments and mornings when the fingers will not close.

The counter-intuitive part: the system rewards hiding pain

When a fighter says the wrist hurts, the default reaction in many teams is suspicion. Not because coaches are cruel, but because the person deciding whether the fighter competes is also the person carrying the medal quota, and those two roles cannot be separated inside a thin delegation. Where there is no doctor independent of the coaching staff with a power of veto, every medical decision becomes a performance decision wearing a white coat.

Another assumption I hear often — that combat sports carry less risk because there are fewer bouts — runs against the data. In football, injuries spread across forty matches, with substitutions and on-site medical care. In combat sports, the entire risk concentrates into one tournament week, inside a dehydrated body, with nobody to come on in your place.

The third counter-intuitive point, and the one I believe most firmly: giving a fighter two extra weeks off does not cost them their place. Re-injury does. Across my 216 combat records, I counted 27 cases of return to competition before the minimum recovery mark; 19 of them were injured again within six months, and 11 spent longer on the sidelines than the time they had tried to save.

The problem is not that Vietnamese fighters like hiding pain. The system rewards hiding it.

If we had to start again from one page

Four things are possible without a large budget. First, a national injury registry for combat sports, mandatory for every athlete on a national-team list: diagnosis, date, mechanism, days lost, return date. Data saves nobody by itself, but it turns pain from a private matter into a systemic one. Second, a medically qualified musculoskeletal practitioner inside the delegation, independent of the coaching staff. Third, in the amateur system, move weigh-in to the same day as competition to eliminate the impossibly short rehydration window. Fourth, baseline neurological testing for every fighter before the season, so that when a head impact happens, we have a line to compare against.

None of those four requires a legendary athlete, a major sponsor or a reform programme. They require one person to sit down and open the first page of the book.

The question I leave with the administrators: when a 22-year-old fighter has to choose between telling the truth about his wrist and being selected to fight, have we designed the system wrong — or are we simply choosing the wrong people?
