Three Kinds of Arena, One Wrong Ruler: Why Vietnamese Combat Sports Lack the Data to Be Analysed

That night I was sitting in the third row of the Lach Tray arena in Hai Phong. A young fighter had just won on points after three rounds. The crowd clapped, the yellow lights fell across the mat, sweat left long streaks on the canvas. The announcer read out his name and got one syllable wrong. Nobody in the post-fight room afterwards could say exactly how many strikes he had thrown, how many had landed, how many he had absorbed. The only thing we had was a result sheet with four words on it: win on points. Plus each person's memory of the fight, and memories differ. I had my notebook open and nothing to write except feeling. Getting a name wrong teaches you a lesson for life. But this time the error was not in the name. The error was that an entire fight had unfolded in front of me and I had not a single number to check what I had just seen. If you ask ten Vietnamese people where their country is strongest in martial arts, nine will answer with medals. SEA Games. Asian Games. World wushu championships. Vovinam. Boxing. Muay Thai. Taekwondo. Karate. Pencak silat. A long list, and every name is a trophy cabinet. That is true, and it is also what worries me. Compare a V.League football match. Thirty minutes after the final whistle you can look up passes, pass accuracy, duels won, distance covered, a heat map for every single player. For a boxing or MMA bout in Vietnam, thirty minutes later you have the result sheet and a blurry phone video filmed from a bad angle by someone in the crowd. I did not come to martial arts as a fighter. I came as a former athlete turned writer and broadcaster. In 2026, at twenty-four, a rookie reporter in Hai Phong, I was at Lach Tray for Hai Phong versus Ho Chi Minh City. I asked the visiting coach a question about his tactical shape. He frowned and said something I still remember word for word: what would a girl know about formations. I was furious but did not argue. I just kept taking notes. Afterwards I spent two nights counting. The young left winger had seven successful dribbles, three chances created, one assist. I wrote a piece on him using numbers I had coded myself from video. It was the most shared piece that week. That year it sent me to a World Cup. The lesson was not that I was good. The lesson was that numbers are the one thing that does not flinch when people doubt you. Data does not betray you; we simply place our trust in the wrong place. If I say he played well, that is an opinion. If I say he beat his man seven times, that is a fact, and nobody argues with a fact. But that fact only exists because someone did the counting. In Vietnamese martial arts, almost nobody counts. The first thing any analyst must understand is that martial arts is not one sport. It is at least three, running on three different logics. Modern combat sports, boxing, MMA, kickboxing, Muay Thai, grappling, are about winning and losing: who stops whom, how, and how fast. The units are knockout rate, submission rate, control time, significant strikes per minute. Then there are forms and traditional disciplines, wushu taolu or the quyen of Vovinam. There is no knockout here. Nobody wins by making an opponent fall. Athletes are scored on difficulty and performance quality. A perfect spinning landing scores high; a fall loses points. This is closer to figure skating than to boxing. Then there is sanda, wushu's combat discipline, allowing punches, kicks and throws. It sits between the two worlds. Why does this matter so much? Because if you take the ruler from the first category and use it on the second, you will draw completely false conclusions. A taolu athlete has no knockout record, not because they are weak, but because their sport does not count that. Vietnam has produced wushu athletes who won continental and world medals with their forms and their swords. On a combat record sheet they are blank. On a movement score sheet they are at the top. I once sat in a panel in Hai Phong where someone said taolu is not real fighting. That is not wrong about combat, but it ignores everything: taolu does not try to be real fighting. Judge it by combat standards and you do not just misjudge it, you erase an entire tradition from the analytical frame. Suppose you want to know how long a Vietnamese boxer can stay at his peak. You need age, pro bouts, accumulated head strikes, injury history, and true walking weight, not the weigh-in number. In Vietnam almost none of that is public or verifiable. The most dangerous gap is weight cutting. Worldwide, rapid dehydration to make a division is one of the leading causes of death in combat sports. A dehydrated brain loses its fluid cushion; a punch that should only stun can become a tragedy. Fighters have collapsed at weigh-ins abroad. In Vietnam, weigh-ins are often held in a small room with no doctor, no hydration monitoring. Without data you cannot spot the fighter cutting too hard. Nobody knows how many kilos he shed in forty-eight hours. The truth is that the hardest cutter is usually not the biggest winner; he is the most injured and the first to retire. But to see that, you have to count. And here, nobody counts. Vietnamese martial arts runs on two tiers that barely talk to each other. The state system, provincial teams, national training centres, SEA Games, Asian Games, Olympics, measures medals. The private and professional circuit, domestic MMA cards, pro boxing nights, corporate traditional events, measures tickets sold. I once watched a national champion from the first tier step into a private show and look lost. Different rules, different crowd. In the state tier you fight for team points; in the private tier you fight to keep the audience. Those two goals do not always point the same way. When you analyse a fighter, you must first ask which system he belongs to. And I keep reminding myself: when the arena is empty, the loudest applause is your own. Many Vietnamese fighters train and compete in front of almost no one. Nobody counts for them, nobody analyses them, nobody sponsors them. They console themselves. That reality is hidden behind every medal tally. I have to say plainly what much of the industry avoids: Vietnamese combat sports has no pay-per-view model. No large rights deals. Event revenue comes from tickets, sponsors, and mostly the promoter's own pocket. A main-event fighter might earn enough to live on for a week; an opener might earn the price of a meal. Without numbers you cannot answer the industry's most important question: where does the money go, and what share reaches the people on the mat? Abroad the revenue split is fought over fiercely. That argument requires numbers. Here it is usually conducted with feelings, and feelings do not pay anyone an extra dong. Another blind spot is judging without a paper trail. Fans see a final scorecard with no reasons. Why did the opponent get round two? Nobody explains. Why was that movement deducted? Nobody publishes it. Without a judging log nobody can learn from defeat. A fighter who loses without knowing why cannot fix it. Then there is doping and clean sport, where in Vietnam there is almost no public information. I say this not to accuse anyone. Silence is not cleanliness; silence is simply the absence of testing. In a system without data, the absence of a charge is not proof of innocence, only proof of a gap. This is the part that hurts most and gets written about least. Cumulative brain injury has been discussed for years elsewhere. Every shot to the head leaves a mark, and the marks add up into a degenerative disease that appears long after the gloves come off. Elsewhere, knockouts, turnaround times and medical suspensions are tracked. Here, barely. But the bigger problem is ageing. What does a fighter live on after retirement? There is no pension, no fallback trade, just twenty years of memories and a knee that aches when it gets cold. Against the light you can still see clearly, and I can see clearly that our sport lacks a system to catch people after they have caught us. There is a mental-health layer almost nobody discusses. Young Vietnamese fighters grow up in an environment where winning is celebrated and losing is abandoned. Nobody prepares them for collapse. Most teams have no sports psychologist. When a fighter loses a big bout, he does not just lose a fight; he loses his own image. The public narrative is flattering: young, hungry, going continental. That story is not false, but it floats free of the ground. A fighter wins a regional event, the press calls him a golden hope, fans expect everything, months later he loses an international bout and opinion flips to finished. Both verdicts are issued with no underlying analysis. Without opponent quality there is no meaning in a result, and nobody here counts opponent quality. Zoom out and the whole industry is a chain: gyms supply the talent, events produce the product, audiences and consumers pay. Every link needs data. None of it is measured here, so the industry cannot learn. Each generation of coaches starts over, inheriting nothing but personal experience. That is the biggest loss of all. Now the contrarian part. What Vietnamese martial arts needs is not a Western data system. It needs a measurement system of its own. There is a subtle trap in the missing-data story. If we import the Western ruler wholesale, knockout rates, significant strikes per minute, control time, we will quietly define success in a language that is not ours. We will look at our most artistic taolu athlete and see a low score on a fight sheet. We will look at a Vovinam competitor and not know what to measure. The paradox is that the disciplines we are strongest in are the hardest to capture with Western metrics, while the disciplines those metrics capture best are where our depth is thinnest. Import the ruler whole and we dim our strengths and magnify our weaknesses, creating a distorted mirror for ourselves. The right path is a dual system: standards strict enough to compare, native enough not to betray each discipline. Score taolu movement quality on our own scale. Judge Vovinam technique on its own terms. And use international metrics for sports the world has debated for decades. Not one or the other, but both, clearly labelled. That night, listening back to the recording, I realised something small. Between two missing numbers, there was still one thing I could write: the story of a person. The problem is not only missing data. The problem is missing people willing to do the counting, and willing to believe the counting is worth it. A sport grows up when it begins to remember. The name of the loser. The number of strikes absorbed. The reason it won. If you are a young reporter, a coach, or a fan: be the first to count. Do not wait for permission. When the arena is empty the loudest applause is your own, but applause that has been written down keeps ringing.
