Before Stepping Onto the Mat: The Data Gap in Vietnamese Martial Arts

The hallway of the Binh Duong provincial arena, 6:40 a.m. A seventeen-year-old fighter sits on the tile floor, back against the wall, hands still wrapped from the previous night's session. Two metres away stands a round-dial mechanical scale on a frayed plastic mat. The weigh-in official says exactly three things: name, year of birth, weight. Done. On the A4 sheet inside a clear plastic sleeve, the notes field is empty. No one records how many kilos he shed in ten days, how many nights he lost sleep, how much water he drank in the final two hours, or how much he will put back before his first bout at three in the afternoon. Those numbers did exist. They just never existed on paper. I was there as a writer. Ten years ago I sat waiting in a similar hallway, but it was the doorway of a medical room, after surgery on my left knee ligament. Back then I understood something blunt: people only count what they can see. Goals, punches, medals. The part that actually decides a fight lives where no one counts. There are cheers nobody hears, but the fight still needs to be told. Vietnamese martial arts run as two parallel systems, and those two systems use two different rulers. The performance system — forms, paired routines, the katas of Vovinam, traditional martial arts, ethnic fighting styles — is scored on a technical scale by a panel of judges, based on difficulty, precision and aesthetics. The combat system — sanda, muay, boxing, wrestling, MMA — is scored by wins and losses, by rounds, by referees' points on the mat. Both systems sit inside the official competition structure: the national traditional martial arts festival, the national championships of each discipline, and then the SEA Games, where wushu sanda and muay are part of the programme. At the professional tier, Nguyen Tran Duy Nhat is the most widely recognised Vietnamese name in international muay, with WBC Muay Thai titles across his career. Truong Dinh Hoang once won a continental belt in professional boxing. Their records are complete, traceable, verifiable. But most Vietnamese fighters have no record beyond a family member's social media post, a few photos with medals, and their coach's memory. In 2026 I was mocked by an entire online community for a week after mispronouncing Luka Modric's name three times during a live broadcast. I apologised publicly, then spent 120 hours rewatching matches and learning how to say the names of all 736 players at that year's World Cup. The lesson I took was not about pronunciation. It was this: to write accurately about a person, you first need data about that person. In football, the data is already sitting in the archive. In Vietnamese martial arts, sometimes the original sheet is blank from the start. In my own notebooks, the pages on youth martial arts tournaments are always thinner than the pages on football, and it is not laziness. I once spent three days at a youth event reconstructing the competitive record of a nineteen-year-old sanda fighter. The result: seven bouts in two years, five wins, two losses. I had to piece that number together from bracket photos of three separate tournaments plus the memory of a coach who had trained him since he was fifteen. No database confirmed it. No written record preserved it. If I get it wrong, no one can correct me, and no one can correct it for him either. The second data layer is weight, and this is where the risk is clearest to me. At one youth event, in the 60 kg class, a fighter weighed in at 6:40 and competed at 15:00. Between those two points lies a gap of nearly eight hours, and inside that gap sits the entire process of rehydration, refuelling and recovery. Nobody measures it. Nobody records it. If he steps onto the mat and collapses in the second round from dehydration, the result sheet will read: loss. There is no box that reads: cause. Major international organisations solved this long ago with official weigh-in procedures, rehydration checks and mandated recovery windows between weigh-in and competition. Those are technical rules, not ceremony. They exist to separate the physical component from the technical component in the final result, so that a bout measures what it claims to measure. The third layer is performance scoring. A forms routine has five judges, scoring on a scale, and the final result is the average after the highest and lowest scores are dropped. That method is sound. The problem is that the score sheets come with no explanation and are not published. Two athletes finish 0.5 apart, neither knows which section cost them, and neither coach knows either. To fix a technical error, you first have to know where the error is. Sealed score sheets mean no one can fix anything. The fourth layer is medical. This is the layer I care about most, and the emptiest one. A seventeen-year-old competing in four events a year, absorbing how many blows to the head, how many strikes to the face, how many times stepping onto the mat before fully recovering — that information lives in his head and in his coach's memory. No long-term medical file follows him across events, across training camps, across transfers. Injury takes away the legs, but it cannot take away the heartbeat of the fight — it only takes away what nobody wrote down. Looking at these four layers, the easiest conclusion is that Vietnamese martial arts lack money. Low prize purses, thin sponsorship, athletes holding second jobs. I believed that for years, and I think that belief has been steering us the wrong way. The counter-intuitive angle sits elsewhere: the problem is not a lack of money, it is applying the wrong analytical framework to the right subject. A forms routine judged by win-loss record produces a meaningless conclusion, because a routine does not win by defeating anyone. A sanda fighter judged by a performance panel's technical score is equally meaningless, because the combat mat does not score the beauty of a technique. Yet that is exactly what happens every time a traditional martial artist's record is placed beside an MMA fighter's record on the same news page, under the same headline, in the same format. A wrong framework does not create small arguments. It creates unresolvable ones, because both sides are talking about two different units of measurement. When electronic scoreboards arrived at performance events in recent years, many expected disputes to fall. I did not see it. Electronic scoreboards move the argument off the stands and into the technical room and the grey zones of the scoring rules, where only a few people have access. The argument does not disappear. It just changes seats. In combat sports the issue is even sharper. A closed ecosystem, where events only compete against each other, where fighters only meet familiar opponents, with no regular international exposure, will never produce genuine stars. A star needs unfamiliar opponents, needs painful losses that are written down, needs a record that outsiders can look up and believe. Without a data layer, a star is only a rumour that circulated long enough. I keep writing, and I keep standing in the hallway. The stands are empty, but I can hear the pulse of a whole city. I am not here to score goals; I am here to record the people who scored them. If the organisers of one youth event in Binh Duong would add three lines to the weigh-in sheet — kilos ten days ago, litres of water in the two hours before the scale, hours slept the final night — then within two seasons we would have something no one has had in ten years: a baseline for comparison. Three lines. No machines, no software, no budget. Just someone willing to hold the pen three seconds longer. There are contests that never appear on a scoreboard; they live in how we wait. And how we wait, in turn, depends on whether we write anything down while we are waiting.
