The Bout Without a File: Vietnamese Martial Arts and the Fight Against the Data Void

In a small gym tucked deep in an alley off Nguyen Van Cu Street in Hanoi's Long Bien district, an August morning begins with the sound of hand wraps. There is no loudspeaker and no big lighting rig — only the stretch of cloth as fingers tighten and a very soft sigh from a man entering the twelfth week of a weight-cut plan. On the wall, a calendar has been crossed out in red marker since mid-July. The person wrapping the hands says nothing. The person receiving the wrap says nothing. In that silence there is no bell, no stands, no flashbulbs. I am used to moments like this. Across nearly sixteen years moving through fight floors and preparation corridors, I have learned that most of the real story of Vietnamese martial arts sits exactly where the cameras do not point. The crowd applauds when a kick lands. Before that kick is a morning no one woke up to witness. After it is a notebook very few people bother to open. The locker room does not lie — it only whispers. It was in those corridors that I learned a paradox about Vietnamese martial arts: thousands of training sessions every day, hundreds of professional fighters, dozens of events year-round, yet the amount of reliable data available to tell its own story is uncomfortably thin. This is what I want to argue here: Vietnamese martial arts is competing without a file. And when a sport competes without a file, every argument in the stands — about referees, about scorecards, about who deserves a national call-up — becomes an argument with no referee. Some context before the details. Vietnam currently runs several parallel competition systems, each operating on its own logic and barely talking to the others. Professional boxing has a national federation plus regional title bodies, with names such as Truong Dinh Hoang and Nguyen Thi Tam having made their mark. Amateur boxing sits under the sports administration, serving the SEA Games, ASIAD and Olympic qualifying circuit. Traditional martial arts and Vovinam have their own tournament structures tied to federations and heritage competitions. Wushu, taekwondo, judo, karate and pencak silat are combat sports within the national system. Muay Thai has a strong community in Ho Chi Minh City and Hanoi, with fighters who have won international honours. And MMA — the youngest — has a domestic promotion that has built real traction with younger audiences. Each system keeps records differently. The sports administration records by targets, medals and national squad lists. Professional organisations record by contracts, rankings and promoter scorecards. Traditional martial arts federations record by belt grades, certificates and competition results. But very rarely are those four ledgers opened side by side on the same table. The result is a systemic paradox: when a Vietnamese fighter prepares to step onto an international stage, the coach has to gather opponent footage from video platforms, reconstruct records from old news stories, and cross-check results from unofficial pages. Work that in developed sporting nations is done in advance by a data system is still being done by hand in Vietnam, by memory, and by the patience of people who are not paid for it. That is the starting point for the analysis below. I will move through eight layers: technique and match-ups, fighter condition and career longevity, the organisational landscape, the business model, rules and governance, health and career risk, the media narrative, and the industry's downstream effects. Each layer circles the same question: what do we actually know, and what are we pretending to know? Start with technique, where arguments flare loudest and evidence is thinnest. Vietnamese boxing coaching splits into a few clear branches. The branch shaped by Cuban and Soviet schools emphasises the lead foot, rhythm, tight defence and counter-punching with the rear hand. The branch shaped by Thailand emphasises low kicks, close-range pressure and durability. The younger domestic MMA branch, learning from Asian promotions, leans towards grappling, submissions and fast finishes. The problem is that when fighters from different branches meet, there is no shared database to compare them. No average significant strikes per round. No grappling success rate. No strike-distribution map across the body. No standardised head-to-head history. What remains is the crowd's memory, and the crowd's memory always favours the most recent winner. A technical match-up without underlying data is just two stories told loudly next to each other. I have watched that happen in Vietnam and in China. Before a fight, fans of each side build a version of their fighter. One side says fighter A has a traditional martial arts base and therefore unpredictable strikes. The other says fighter B has pure boxing fundamentals and therefore superior speed. After the fight, one of those stories collapses. But nothing is recorded so that next time we make fewer mistakes. In traditional martial arts and Vovinam, the problem runs deeper. These disciplines have grading systems, forms and sparring. But a sparring bout between two Vovinam fighters and a bout between two fighters from another discipline cannot be compared on any neutral scale. People settle it by feel, by the reputation of the training hall, by years of practice. All of those are unmeasurable variables. Honestly, I do not believe claims of the type 'this fighter is clearly stronger'. I believe in specific comparison frames: in this situation, under these rules, at this weight class, with this training background. Outside those frames, every comparison drifts into the territory of belief, and belief does not need data. The second layer is fighter condition and career longevity. This is where the data void does direct, measurable harm. In Vietnam there is no national database of fighters' injury histories. No record of how many weight cuts a fighter has done across a career. No long-term neurological monitoring after bouts with heavy head contact. In boxing, a fighter can lose five to seven kilograms within thirty-six to forty-eight hours before weigh-in. In sports with tight medical systems, that process is monitored, electrolytes are measured, urine is checked, and sometimes the bout is cancelled to protect the fighter. In Vietnam, most of that process happens in the silence of a sauna and inside the fighter's own decision. I once stood outside a weigh-in room in Ho Chi Minh City and watched a fighter step on the scale with cracked lips and trembling hands. He made weight. No one asked anything more. He fought that night. No one recorded the degree of dehydration he entered the fight with. Three weeks later, there was no report on how he recovered. That is the kind of loss that never shows on a scorecard, but it accumulates. A Vietnamese fighter can typically compete professionally for six to ten years. Then he leaves the floor. In most cases he leaves without a medical file detailed enough for a doctor to know what is being treated. Every time hand wraps are put away, a fighter loses not just one bout — he loses a slice of career that no one is measuring. This is where I see developed sports holding a structural advantage. They do not necessarily have better fighters individually, but they have a system that knows when a person must be stopped. That system does not need medals. It needs a computer and a process. The third layer is the organisational landscape. This is the most complicated part, because it involves power. Vietnamese martial arts has multiple actors coexisting. There is the state sports administration. There are discipline federations. There are private event companies. There are gyms and training halls acting as talent pipelines but sitting outside any formal system. There are regional title bodies operating across borders. Between these actors there is no unified system for competition rights, rankings or ratings. A fighter may hold one organisation's belt while being absent from another's list. A national champion in the state system may never have faced the champion of a privately run promotion with a much larger audience. As a result, titles in Vietnam are local in scope. That does not diminish their sporting value, but it leaves fans with no way to determine who is genuinely the best at a given weight. And when the public cannot identify the best, the market cannot identify whom to invest in either. I followed one telling case years ago. A young fighter won a regional event. Media coverage was broad. Three months later he appeared on a different stage and lost. No one explained where those two events sat on the same board. Fans were simply confused, then turned to another story. The fourth layer is the business model. This is where the local nature of the data turns into financial damage. A martial arts event in Vietnam has several revenue sources: live tickets, sponsorship, media rights and merchandise. Sponsorship and rights are the two biggest, and also the two hardest to sell. A sponsor wants to know real viewership, audience demographics, digital engagement and return frequency. A broadcaster or streaming platform wants stable numbers to price a contract. None of those datasets is produced regularly in Vietnam. As a consequence, sponsorship and rights deals are usually priced on perception and relationships. An event drawing ten thousand spectators may sell a smaller sponsorship package than an event drawing four thousand with better ties to decision-makers. Repeated over years, that asymmetry produces an opaque market where rewards do not flow to those doing the best work. At the bottom of the pyramid sits fighter pay. Most professional Vietnamese fighters cannot live on competition income alone. They coach, they train others, they open gyms, they take security or delivery work between camps. This income structure means every fighter has to operate as a small business, and time devoted to craft gets fragmented. I do not score goals, but I remember every breath of the stands. That breath tells me something no sponsorship deck says: Vietnamese audiences are willing to pay to watch martial arts. What they are not given is the certainty that the money flows to the right place and creates a stable standard to follow. The fifth layer is rules and governance. This is the most contested layer and also the most misunderstood. When a fight ends on a referee's decision and the crowd reacts, the reaction usually targets the individual referee. But the root of the problem usually lies in the scoring system, and in whether that system is published, explained and audited. In boxing, the ten-point must system has to be clearly specified: criteria for clean strikes, for effective aggression, for effective defence. In MMA the criteria are more complex, combining striking, grappling and control. If these criteria are not published to the public and applied consistently, every decision becomes suspect. In Vietnam there have been bouts whose results were argued over for a long time. In most cases, organisers respond by asserting the decision was correct, without publishing a detailed round-by-round scorecard. Without a public scorecard there is no basis for scrutiny. Without a basis for scrutiny, every explanation is simply an assertion. On doping control, this area is nearly empty at the domestic professional level. Amateur events inside the sports system have testing procedures when needed. Private professional events rarely run regular procedures because costs are high and no body mandates them. This puts Vietnamese fighters in a doubly disadvantaged position: lacking protection, and lacking proof of clean status when they step onto international stages. A sport without audit has no integrity, even when everyone inside it is clean. I have to say this plainly, even if it is uncomfortable. As a reporter I cannot confirm what I cannot check. And in Vietnam right now, much cannot be checked. The sixth layer is health and career risk. This is the least discussed layer and the most expensive long term. The three main risk groups are brain injury from cumulative trauma, complications from rapid weight cuts, and the loss of security after retirement. On brain injury, the greatest risk sits in disciplines with continuous head contact. In sports with structured systems, fighters stopped by knockout get a minimum medical rest period and usually must be assessed before being licensed again. In Vietnam, that rest period depends on the decision of each event's organiser, and no database tracks a fighter across a whole career. On weight-cut complications, this is a risk that can be prevented by process. Severe cases usually occur when a fighter cuts too fast, without medical supervision, and has to compete immediately after making weight. International standard procedure requires an official weigh-in, then a recovery window, and a second weigh-in on fight day. In Vietnam, most events hold only one weigh-in. On post-retirement security, this is structural. A fighter retires at thirty-five with accumulated injuries, some coaching skills, and no sporting pension. If they manage to open a gym, they are fine. If not, they move into another trade and disappear from the sport they gave their youth to. The seventh layer is media narrative and market expectation. This is the layer I watch most closely, because it relates directly to my job. In Vietnam, martial arts has a loyal audience, but that audience has not been converted into pressure for reform. The main reason is that domestic martial arts coverage focuses heavily on fight results and personal stories, not on systems. An article about a championship-winning fighter will get many readers. An article about weigh-in and recovery protocols will get few. But if only the first type exists, the sport never fixes its own recurring errors. In developed sports, the second type exists alongside the first and slowly builds pressure on organisations. Within this layer sits the issue of manufactured conflict. Part of martial arts media depends on creating tension between fighters before a bout. That tension can be genuine or a marketing construct. The line between the two is hard to draw, and once audiences know tension can be staged, the value of even genuine tension gets dragged down. The eighth layer is the industry's downstream effects. At the source sit gyms and training halls. If the professional competition system does not offer a clear pathway, gyms focus on teaching and self-defence rather than building a competitive talent pipeline. In the middle sit media and rights, dependent on audience data. At the end sit adjacent industries such as equipment, nutrition, medical care and related services. A blockage anywhere in the chain slows the whole thing. In Vietnam's case, the biggest blockage sits in the middle: no reliable audience data, no stable subscription-based content distribution, and no unified ranking system to turn scattered events into a season with continuous flow. There is a dimension of this story I have to state bluntly. In the digital sports industry, live data is something international betting operators pay very high prices to obtain. When a sport has not yet built a standard data system, the pressure appears first not from fans wanting to understand fights, but from parties wanting to monetise betting flow. This has happened in many places worldwide. First, someone provides free results data. Then they provide paid live data. Then the same data stream is separated and sold to betting companies. Finally, the sport realises that part of its data infrastructure is operated by parties with no shared interest in the sport. Data is the bloodstream of a sport, and that bloodstream should not be pumped by outsiders. I have seen this up close, and I understand why young promotions are tempted. Accepting free distribution and data support looks like an advantage. But in exchange for that convenience, you lose control of your own story. Now comes the part where I want to differ from the consensus. Many people look at the data void in Vietnamese martial arts and immediately conclude the sport is backward, weak and unprofessional. I think that reading is too fast. The data void is not only a weakness. It is also a shield. When there is no fighter file, no standard odds, no standardised head-to-head history, part of that is the system's slowness, but another part is an accidental resistance against forces that any sport with good data must face: performance betting, fixed results, and the penetration of black money. Put differently: Vietnam lacks data, but Vietnam is also not being steered by data controlled by parties with no stake in Vietnam. When someone proposes building a national martial arts data system, my first question will not be 'how long will it take', but 'who owns it, who operates it, and to whom can that data be resold'. This is the point I think Vietnamese sports leaders should consider before getting excited about digitisation. A data system can serve two very different purposes. It can help fighters understand what an opponent possesses, help doctors know when to intervene, and help international promoters assess domestic fighters properly. It can also help a betting company on another continent know exactly when to open a market. The shift from the first purpose to the second does not happen in one leap. It happens step by step, each step with its own reasonable justification. That is why I am strict about the phrase 'having data is good'. Having data is neutral. Who owns the data is the decisive question. In Vietnam, the sports system has an advantage many countries lack: the state is still present as a regulator. If a national data system is designed from the outset with clear ownership rules, a ban on resale for betting purposes, and independent auditing, it will be a protective platform rather than a risky one. That window is open now, and it will not stay open long once private players occupy the infrastructure. I also want to address another misunderstanding. Many people assume Vietnamese martial arts lacks data because it lacks money. That is partly true, but not the main cause. The cost of recording a fight with two cameras and storing results systematically is not high. The cost of maintaining a fighter database with basic information is not high. The main cause is that no one has official responsibility for it, and no mechanism compels it. This is the difference between lacking resources and lacking process. In sports with less potential than Vietnam, people still have rankings, fighter files, head-to-head histories. They manage it because there is a rule that organising an event requires publishing results in a standard format, and those results must be lodged in a shared archive. So what would change this picture? In my view, there are three signals worth watching in the near future. The first signal is the emergence of a body or organisation publishing a shared ranking for at least one competition system. If that ranking is updated regularly, has transparent criteria, and is recognised by major organisations, it would be the most important shift. In martial arts, rankings are instruments of power, and sharing that power is something no organisation wants to do. The second signal is a domestic professional promotion adopting a two-stage weigh-in: official weigh-in and fight-day re-weigh. It is a small technical detail, but it reflects the degree of professionalisation. A promotion adopting this procedure is saying it cares about fighter safety, and it has enough resources to run a more complex process. The third signal is a group of Vietnamese fighters organising their own professional association. In many sports, breakthroughs on welfare and rights come not from promoters but from athletes organising together. In Vietnam that has not happened yet, but the conditions are forming as more fighters live entirely off competition income. Finally, I want to return to the gym in Long Bien. The man crossing out the calendar each day, the person wrapping his hands, and the scale in the corner of the room — none of that appears in any record book. But they are data. They are the real units of a sport. And until someone sits down to record them, every debate about who is better will remain two sides shouting at each other in a stadium with no referee.
