The "Martial Arts" Label Is Wiping Out Vietnam's Sports Analytics

Four Cells, Four Zeros

The evaluation sheet came back with four cells, and all four read zero. Competitive value: 0. Industry value: 0. Timeliness value: 0. Reference value: 0. Not a single line in the information extraction, no entities, no core viewpoints, no sources. An empty column went out, an empty column came back, with an apology note attached.

My first reflex was to hunt for a data-entry error. My second reflex is the one worth talking about. The second-highest risk warning in that sheet was not about input errors. It said the domain label "martial_arts" remained unclassified, and asked for clarification on whether the subject was modern combat sports or traditional martial arts. The system refused to guess.

I sat staring at that sheet longer than necessary, because it described precisely the disease I have lived with for five years in this job. Every time I request a clean dataset on Vietnamese martial arts, what comes back is usually a compiled table where a karate medal sits beside a vovinam medal, where a ten-round professional boxing bout is counted alongside a taolu routine lasting one minute and twenty seconds. Those tables look very substantial. And they are meaningless.

The zero in that analysis sheet is an act of honesty. It says: there is no basis for analysis. The problem is that when our martial arts media encounters exactly that situation, we do not stop. We average it out.

I need you furious before you agree. That is the only moment you will actually listen.

One Word Covering Ten Rule Sets

On a SEA Games finals night hosted by Vietnam, three competition venues ran in parallel. A boxing ring in a provincial town, a karate hall, a pencak silat mat. Three different rule systems, three different referee panels, three different scoring logics, three different athlete record sets. On our newsroom desk, all of it collapsed into one word: martial arts.

Based on my own experience tracking fights, I can say that "martial arts" in Vietnamese sports copy is one of the most damaging words for analytical capability. It is not wrong linguistically. It is wrong in terms of measurement.

Count what sits under that label. Wushu has two completely separate branches: taolu performance and sanda combat. Karate has kata and kumite. Taekwondo has poomsae and kyorugi. Then judo, pencak silat, wrestling, amateur boxing, professional boxing, muay thai, kickboxing, MMA, BJJ, vovinam, traditional martial arts. That is more than ten rule systems, spanning at least six different international federations, with five scoring logics that have nothing to do with one another.

In 2026, when I was eighteen and had just set foot on campus, Neymar's 222 million euro transfer from Barcelona to PSG blew up every newsroom. I wrote a contrarian piece titled to argue that Neymar would never win a Ballon d'Or in a league with only one team. Friends called me delusional. From that student blog, I learned that if you want a big bang, you have to light the fuse yourself. But I learned a second, less-discussed thing: a fuse only detonates when you have already defined what you are measuring. With Neymar, the unit was Champions League titles and individual awards. With martial arts, we have never defined the unit.

One evening, after hosting a podcast episode about the SEA Games, I tried something simple: open the medal table and split it by discipline. It took forty minutes. No ready-made tool existed. I had to open each results page, type it manually into a spreadsheet, and by the thirtieth cell I realized I was mixing three incomparable data types: subjective judge scores, round-by-round referee counts, and knockout results.

That was when I understood why every martial arts analysis in Vietnam ends at medal counting. Not laziness. The label permits nothing else.

Three Axes That Do Not Convert

To compare two athletes, you need three identical things: competition frequency, definition of victory, and the referee's error budget. In martial arts, all three differ across every pair of disciplines.

The first axis is sample frequency. A national-level taolu athlete competes officially two to four times a year, each time one routine or one weapon form. An amateur boxer may fight four to eight times a year. A professional boxer fights two to four times. A professional MMA fighter also only two to three. That means after five years, one athlete has ten data points and another has forty. Any side-by-side "career win rate" is comparing two sample sizes that differ fourfold.

The second axis is the definition of victory. Boxing and muay thai use the mandatory ten-point must system: each round, the winner takes 10, the loser 9 or 8, and the fight is won on the total of three scorecards. Wushu taolu uses three separate judging panels, where Panel A scores movement quality on a 5.00 scale, Panel B scores overall performance on a 3.00 scale, and Panel C scores difficulty on a 2.00 scale, per the International Wushu Federation's standard scoresheet. Three judges produce three different numbers, and the winner may lead by just 0.02. Judo awards outright victory by ippon, and since 2026 the International Judo Federation abolished the yuko level entirely, leaving only ippon and waza-ari. BJJ scores by technical action: takedown 2 points, sweep 2 points, guard pass 3 points, mount 4 points, back control 4 points. Professional MMA follows the unified mixed rules adopted by the state of Nevada in 2026, and a fight can end by knockout, submission, or three judges' scorecards.

A "win" across those five systems is five different concepts. Adding them together is like adding football goals to basketball points and calling the result "scoring output".

The third axis is the error budget. In taolu, Panel B scores aesthetics, and aesthetics shift with each panel. In karate kata, judging panels score two groups, technical and athletic, also on sensory criteria. In boxing, a 114-114 scorecard can destroy a career, and scorecard controversy is a permanent feature of the sport. In MMA, the notion of a 10-8 round has no clear quantification for "degree of damage".

These three axes produce four rule-scoring groups that cannot be merged: fully subjective judging panels, round-by-round ten-point counting, accumulated technical actions, and fights decided by knockout or submission. Any dataset that blends these four is manufacturing noise.

Most Talked About, Thinnest Data Footprint

There is a paradox I found when auditing my own keyword archive. In Vietnamese, the keyword cluster around vovinam and traditional martial arts has markedly higher search and article volume than the cluster around wushu taolu or pencak silat. But when I tried to find a longitudinal dataset for vovinam and traditional martial arts, what I found was close to nothing.

The reason lies in competition structure. Vovinam and traditional martial arts have domestic tournament systems, federations, and congresses, but no unified professional international rulebook at commercial level, so they generate no longitudinal athlete records: no fight sequences, no encoded weight classes, no public scorecards per appearance. Wushu taolu, meanwhile, has standardized scoresheets, a long-running world championship, and clear cross-reference records, yet a significantly smaller mass audience.

The most heavily covered segment has the thinnest data footprint. The segment with the cleanest data has the fewest readers. That imbalance explains almost the entire quality level of martial arts analysis in Vietnam.

This paradox is not uniquely ours. It is structural. Disciplines without unified rules at professional level will never generate comparable data, no matter how socially popular they become. A discipline with hundreds of thousands of practitioners across gyms, but which organizes competition under the separate regulations of each provincial federation, will forever lack a ranking table.

Medals Are the Only Convertible Unit

Because performance cannot be compared, media defaults to the only comparable thing: medals. A SEA Games gold in karate and a gold in boxing are both one gold. Counting them is easy, adding them is easy, and most importantly they require no understanding of competition rules.

Medals are the only unit convertible across more than ten different rule sets, and precisely for that reason they are the only unit Vietnamese martial arts media knows how to use.

The knock-on effect lands elsewhere. When the entire vocabulary of the industry revolves around medals, readers never learn to look inside a fight. They know a gold was won, but not whether it came from a third-round tactical switch, a change of pressure direction, or an opponent deducted for a technical foul. Every tactical question gets pushed outside the news frame.

I committed exactly this error and I will not pretend to be innocent. In 2026, I wrote a piece mocking Real Madrid's signing of Tchouaméni, arguing he won on statistics but lost on character. His agent called me, laughed, and said the criticism actually relieved their pressure. Four months later, at the World Cup in Qatar, I wrote that Argentina would go home early after losing to Saudi Arabia. They won the tournament. I had to correct myself publicly with an analysis of Enzo Fernández's role in the system. That same agent later tipped me off that Chelsea had triggered Enzo's 120 million euro release clause. I published at two in the morning and became the first Vietnamese outlet with the story.

The lesson is plain: I have the network to get scoops, but I still tend to start from an assertion rather than a number. In football, that mistake can be rescued by an exclusive. In martial arts, nothing rescues it, because no exclusive is good enough to fill the gap left by a dataset that does not exist.

What Is Actually Changing

There is one new direction I consider worth tracking, and it comes from the least-watched place: domestic professional promotions.

When a professional MMA event is staged regularly in-country, it automatically generates four categories of data Vietnamese martial arts has never had. First, weight classes encoded to a unified standard, typically the eight divisions from flyweight to heavyweight under international mixed rules. Second, longitudinal fighter records with bouts, rounds fought, and finish rates. Third, absolute competition dates, enabling a real timeline. Fourth, event-level payroll and gate revenue, meaning sports-business data that Vietnamese football has but Vietnamese martial arts has almost never disclosed.

Weight class is the most important piece of that, and the reason is that it turns a vague variable into a comparable one. When you know two fighters sit in the same weight band, every subsequent performance comparison has a fulcrum. Wushu taolu has no weight classes because it does not need them, but karate kumite, taekwondo kyorugi, boxing, judo and wrestling all do. A shared comparative axis across combat disciplines has existed for a long time; nobody in Vietnam has assembled it into a database.

At the same time, competition adjudication has moved some distance toward transparency. In international taekwondo events, poomsae scoring splits into accuracy and presentation. In karate kata, judging panels publish technical and athletic criteria. In judo, dropping yuko made the scoresheet leaner and more countable. These changes are invisible to casual audiences, but they are prerequisites for any analysis to exist at all.

I do not believe the story that "technology will solve everything". High-speed cameras and touch-detection systems only help when a stable rulebook already exists underneath for cross-referencing. In martial arts, what has been missing is a stable common rulebook, not machinery.

Where I Could Be Wrong

Three possibilities would collapse my argument, and I want to state all three.

First: perhaps audiences do not need the granularity I am demanding. Vietnamese fans cheer for the flag, and a gold medal delivers an emotion no data table ever will. If I split martial arts into ten separate silos, I please a small group of specialist readers and lose most of the audience paying for my podcast. I have to be honest: my income depends on the very label I just attacked. This is not a neutral argument, however much I try to make it one.

Second: perhaps the label is correct at the grassroots level. At gifted schools and provincial training centres, the same cohort of thirteen-to-seventeen-year-olds typically rotates between disciplines based on recruitment quotas each cycle. A kid training wushu this year may switch to taekwondo next year, then pencak silat if that cycle has a slot. If they genuinely operate as one system at the development level, then calling them by one name is accurate description. I may be applying a professional data-industry standard to a system whose connectivity lies in people, not in competition rules.

Third, the least comfortable possibility, because it turns back on me. I have five years embedded in fight sports, a backchannel network wide enough to know behind-the-scenes stories about contracts and selection, and I have almost no data file clean enough to cite. I spent five years commenting on other people's lack of data instead of building a dataset myself. Someone who complains daily that the pitch is dirty, while never raking a single leaf, has no standing to criticize the pitch.

People remember me for the explosion, but I remember myself for bending down to write. And bending down to write, in this case, means sitting down to open every tournament results page and type it in, exactly like that evening when I opened the medal table and quit at cell thirty.

A hot take is never the answer. It is a kick to make others want to argue. But a kick only has value if someone actually steps into the fight afterwards.

The Test Until 2027

This is my falsifiable judgment, and I am writing it down to check against later: if by the end of 2027 no public database in Vietnam separates at minimum the four scoring-rule groups I outlined, then every martial arts analysis in the country will remain stuck at medal counting. Not because writers are weak. Because there is no raw material.

Conversely, if even one discipline manages it, I believe its coverage depth and the quality of debate around it will change within two SEA Games cycles. Sports media history confirms this in football, where goal and possession data turned arguments from sentiment into debates with a fulcrum.

I was right when I said Neymar would never win a Ballon d'Or in a one-team league, and right when I said Germany would exit at the group stage at the World Cup they entered as defending champions. Both times, I was right because I chose a measuring stick beforehand and accepted letting it judge me. For Vietnamese martial arts, that measuring stick does not yet exist. Whoever builds it first will get to write the history of these disciplines with data instead of inspiration.
