Two Reference Systems of Vietnamese Martial Arts: Combat Has Data, Forms Have Memory

On May 19, 2026, at the Bac Tu Liem Arena in Hanoi, I sat in the press area with two screens in front of me. The left screen showed vovinam combat. The right screen showed a team forms routine. Within roughly forty minutes, two gold medals were awarded.

For the first medal, I held a full dataset: strikes thrown, strikes landed, accuracy rate, rest time between rounds, number of warnings. For the second, all I had was an unpublished judges' scorecard and a video clip lasting two minutes and forty-seven seconds that nobody in the press room could use to pinpoint exactly which second had cost a deduction.

I wrote in my notebook: Two golds. One data system. One blank space.

Then I realised the problem was bigger than a single night of reporting. Both events are called by the same name: martial arts. Same delegation, same line on the medal table, same headline in the newspapers. But they operate on reference systems so different that if I sent a boxing coach to judge a forms routine, he would not know where to begin. And if I sent a forms judge to score a combat bout, he would call almost everything wrong.

That is the starting point of this piece.

One label, two ecosystems

In the administrative records of Vietnamese sport, the phrase martial arts is a large umbrella. Underneath it sit boxing, kickboxing, muay, taekwondo, karate, judo, wrestling, pencak silat, vovinam, wushu, traditional martial arts, and more recently mixed martial arts. Each has its own federation or subcommittee. Each has its own rule set, its own scoring system, its own way of recording results.

But on the medal table, all of it collapses into a single number. And in the newspapers, all of it collapses into a single headline: Vietnam's martial arts team has won more medals.

This collapsing is nobody's fault. It is the natural consequence of organising sport by administrative unit rather than by technical unit. But it produces a very concrete technical consequence: resources, coaches, strength specialists, doctors, and reporters are all shared between two worlds with entirely different needs.

I have followed national martial arts events since 2026. Across those eight years, the pattern I have seen most often is a particular kind of scheduling trade: a combat coach is assigned to support a forms squad in the final stretch, or the reverse. The results are usually not bad, but never good either. Because those two worlds optimise for different things.

Combat optimises decision-making under live opposition. Forms optimise the ability to reproduce a movement sequence under psychological pressure but with no opponent present.

Those are two different problems, requiring two different training programmes, two different recovery protocols, and two different measurement systems.

Combat: where numbers carry legal force

Start with the world that has the most complete data.

In professional and semi-professional boxing, the 10-point must system imposes a very clear logic. Each round has ten points split between two fighters at 10-9 for the round winner, 10-10 for a drawn round, 10-8 when there is a knockdown, 10-7 when there are two. Those scores are recorded by three independent judges, and every card must be signed, submitted, and at many international events published publicly after the bout.

Which means that in boxing, every dispute over a result has a document to dispute. Fans can photograph scorecards, post them online, and cross-check round by round. A judging error in round three can be discovered and re-analysed the next morning. This is a level of transparency few sports achieve.

In mixed martial arts, the scoring system combines three criteria in priority order: effective striking, control time, and the ability to impose the fight. Add to that very specific technical rules about what counts as a legitimate knockdown, what counts as a completed submission attempt, and what counts as counter-striking. Every bout at major professional events comes with a detailed round-by-round statistics sheet: strikes thrown, strikes landed, accuracy by target area, takedowns, escapes.

In wrestling and grappling, scoring is more technical still. A successful takedown is scored by the position it ends in; a reversal from bottom to top is scored by the level of control. It is a system where, just from the score sheet, a knowledgeable observer can reconstruct almost the entire bout.

In Vietnam, this layer of data exists in full only at certain international events or at professional shows run by private promoters. At national and youth level, data usually stops at the final result plus the winner's name. No round-by-round statistics. No coded video. No per-bout injury data.

Forms: where numbers carry aesthetic force

Now the second world.

In wushu taolu, the current scoring system splits marks into three groups. Group A scores movement quality, maximum five points. Group B scores overall expression and rhythm, maximum three points. Group C scores technical difficulty, maximum two points. Each group has its own judges, and the final score is the average after the highest and lowest marks are dropped.

Technically this is a sound system. The problem lies elsewhere: the component scorecards are almost never published. You know the total. You do not know the breakdown. You do not know which judge awarded what, or why.

In karate kata, scoring criteria comprise seven technical elements and four athletic ones, all descriptive and qualitative. In taekwondo poomsae, criteria cover accuracy of movement and presentation, again descriptive and qualitative. In vovinam forms, judging panels score on detailed scales, but whether component detail is published depends on the organiser.

What does this mean in practice?

It means a forms athlete can win with 9.32 points and lose with 9.31, and nobody — including their own coach — can say precisely which movement cost the difference. In a discipline decided by tenths, the absence of component data turns improvement into a disciplined guessing game.

I once asked a forms coach how he corrects a student after a narrow defeat. His answer: we watch the video, we guess what the panel did not like, then we change several things at once to raise the probability. That is a reasonable method. But it is the method of a laboratory that is not allowed to read its own measurements.

Three layers of blank space

From direct observation and from event records I have cross-checked, the data gap in Vietnamese martial arts sits at three different layers.

The first layer is bout data. For combat, that means round-by-round technical data. For forms, that means component score data. Both are missing at national level.

The second layer is longitudinal athlete data. A Vietnamese boxer entering adulthood at eighteen may have fought thirty amateur bouts across four provinces, but there is no record showing whether their average strikes per round rose or fell over three years. A forms athlete may win three medals at three different events without anyone recording how many times they lost balance on the difficult movements.

The third layer is health data. Head injury cases in a season. Average recovery days after a three-round combat bout. Number of athletes cutting weight excessively before competition. Recurrent knee injuries in athletes over twenty-five. These are numbers any serious sporting system should have on the desk before planning a season.

I have tried to find these numbers at several Games and national championships. In most cases, they do not exist in a retrievable form.

The vovinam case: deep medals, thin records

Vovinam is the clearest example of this paradox.

It is the Vietnamese martial art with the deepest international record among traditional styles that have been turned into competitive sport. It has appeared at regional Games since the early 2010s and became a steady source of medals for the Vietnamese delegation at several subsequent editions. At the Games held on home soil in 2026, vovinam was among the sports contributing the most gold medals to the host delegation.

But look at the technical records of the sport and you see a very different picture.

A vovinam athlete can compete in both combat and forms at the same event. Those two disciplines are scored under entirely different systems. Yet in the record of achievements, both are logged as a vovinam medal. In news reports, both are called a martial arts gold.

For anyone working with data, this collapsing is a small disaster. You cannot compare a combat athlete with a forms athlete. You cannot say whether the sport has high or low competitive density if you merge the two sets. You cannot evaluate a coach's quality if you do not know which discipline they train.

On health, the blank space is even clearer. Vovinam forms carry low injury risk but demand enormous volumes of repeated work at the hip, knee and ankle. Vovinam combat carries markedly higher risk of head and lower-limb injury. These two groups need two different injury prevention programmes. I have never seen a national injury report that separates them.

The MMA case: data comes from the market, not the state

At the other end of the spectrum, Vietnamese mixed martial arts is the counter-example.

Domestic professional MMA shows began appearing in the early 2020s, and the first thing they brought was not technique but data. A professional promotion must publish its fighter roster, head-to-head records, weight classes, bout results, and method of victory. That is a requirement of paying audiences, sponsors, and legal betting in markets that permit it.

In other words, data here is generated by commercial pressure, not by administrative rule.

This produces an interesting paradox. A Vietnamese professional MMA fighter can have a more detailed technical record than an amateur boxer who has competed at a regional Games, simply because his bout was streamed to a paying audience while the other's served a medal target.

The flip side is that the data does not belong to the athlete. It belongs to the promoter. When a fighter leaves the promotion, the record usually does not travel with them. There is no national database a national team coach can query when scouting.

The boxing case: transparency at the top only

Boxing has the most transparent scoring system of all martial arts. But in Vietnam, that transparency is concentrated at the top of the pyramid.

At major international events, everything is documented. At national youth championships, things usually stop at the final result. A sixteen-year-old national youth champion may have no record at all of how many rounds he fought, how many times he was counted, or how many times he was cautioned across the tournament.

I know this because I once tried to reconstruct a young fighter's record after she won a regional medal. I needed to know how many rounds she had fought at the preceding national championship. Nobody had the number. I had to contact her coach, who had to dig through memory and a paper notebook.

This is the point I want to stress: the problem is not that Vietnamese people refuse to keep records. The problem is that record-keeping was never designed as a mandatory part of the competition system. When something is optional, it gets done when there is time, and it disappears when time runs out.

GPS numbers do not lie, only the people reading them do

I came to martial arts from track and field, which is why I look at this sport through the eyes of someone used to movement data.

In athletics we have devices measuring speed, stride frequency, ground contact time, foot placement angle. In swimming we have split times per fifty metres. Those sports went through decades of building a data culture, and the result is an extremely dense analytical ecosystem.

Martial arts could follow the same path. An accelerometer on a belt can measure hip rotation force in a kick. A high-speed camera can measure the time from initiation to contact. Pose recognition software can count balance losses within a forms routine. These tools are now cheap enough for a provincial training centre to afford.

But when the tools exist and the data still does not, the problem lies elsewhere. It lies in nobody being assigned to read that data, and nobody having the authority to require it be stored.

On one reporting trip to a provincial traditional martial arts event, I asked the organisers whether forms scores were stored digitally. The answer was yes, but only in the judges' paper minutes, and those minutes would be filed at the provincial department's tradition room. I asked whether anyone had ever entered those numbers into a computer. The answer was no.

Which means that right now, the competitive history of a martial art centuries old exists as paper in a cabinet, and the cabinet cannot read.

When I mispronounced a player's name, I learned to listen to the match

I brought one lesson from 2026 into martial arts, and it still holds.

That year, during a World Cup opening match, I called a midfielder's name wrong three times in the first half. Social media reacted fiercely. I did not delete the post. I published an apology, then spent thirty days rewatching forty matches to transcribe how players' names are pronounced locally, and built a glossary with cultural notes.

The lesson was not that I must pronounce names correctly. The lesson was: when you do not understand a name, you do not understand a person, and when you do not understand a person, you will describe their match wrongly.

I apply that to martial arts. Before writing about an athlete, I check the name, the middle name, the hometown, and the local nickname. I ask coaches what they call their students in the gym. Some athletes are known in their province by an entirely different name from the one on the competition entry form.

Those details never appear in the final article. But they decide whether the final article is correct.

Combat has data, but the data does not belong to the fighters

This is where I want to linger, because it is the biggest blind spot in the whole system.

In amateur boxing, scorecards belong to the organiser. In professional MMA, bout data belongs to the broadcaster. In vovinam, judges' minutes belong to the event organiser. In wushu, component scorecards belong to the federation.

The athlete creates the data but does not own it, cannot access it, and often does not know it exists.

The first consequence is negotiation. A fighter moving from amateur to professional needs to demonstrate value. Without a technical record, he can only demonstrate it through win count. Win count is a very crude indicator, and it can be inflated by choosing weak opponents.

The second consequence is medical. A fighter transferring to a new national squad needs an injury risk assessment based on competitive history. If that history does not exist, the team doctor starts from zero, and the athlete carries the risk during the initial adaptation period.

The third consequence is public. Fans want to compare generations. They want to know whether today's fighter is stronger or weaker than one from a decade ago. Without data, the comparison becomes an emotional argument, and emotional arguments never end.

Forms lack data because they lack storage, not because they lack technique

On the forms side, I want to break a misconception.

There is a widespread belief that forms disciplines do not need data because they are artistic. That belief is wrong at the premise. Forms disciplines have very rigorous scoring systems, in some respects more rigorous than combat. Group A in wushu taolu scores movement quality across five points, meaning every small postural error has a defined point value. That is a level of detail many other sports lack.

The problem is at the storage layer, not the technical layer.

Judges know exactly what they are deducting for. They write it on the card. The cards are collected. But the chain of action from paper card to digital database barely exists. Nobody is paid to do it. Nobody is required to do it.

Meanwhile, forms are where data would have the highest value. Because technical improvement in forms is a very slow process. If you have component score data across three seasons, you can see an athlete improving in Group C but stalling in Group A. You can see a routine losing most points in Group B, meaning the issue is rhythm rather than technique.

Without that data, a coach relies on one person's intuition.

Traditional martial arts and the question of purpose

Here I have to say something rarely said plainly inside the industry.

Traditional martial arts do not need medals. But traditional martial arts need records.

National traditional martial arts festivals are large-scale events, mobilising thousands of practitioners from many provinces and cities, and they have been held regularly for many years. This is one of the largest popular sport movements in Vietnam by participation numbers.

But look at the output, and almost all the value sits in the moment. A beautifully performed routine is filmed on a phone, posted online, shared, and then disappears. No movement record. No instructor dataset. No learner database.

If the purpose of traditional martial arts is cultural preservation, then the absence of records is a heritage problem. If the purpose is sport, then the absence of records is a technical problem. Either way, the conclusion is the same: we are holding memory in the minds of living people.

And the minds of living people have an expiry date.

Weight cutting and the cost of not measuring

Now a more uncomfortable subject.

Weight cutting is common practice in combat martial arts. Fighters drop weight rapidly before the weigh-in, then rehydrate afterwards. In many cases the water loss happens within twenty-four to seventy-two hours.

This practice carries clear medical risks: impaired kidney function, electrolyte imbalance, reduced cognitive performance, increased risk of brain injury when struck in the head while dehydrated.

Major international federations now have rules on multiple weigh-ins and body water monitoring. Those rules were built on cumulative injury data gathered over decades.

At national and youth level in Vietnam, that data barely exists. You cannot know how many young fighters in a season dropped more than five percent of body mass within forty-eight hours of weigh-in.

This is where I want to be plain: the absence of data at this layer is not an academic issue. It is a safety issue.

On one evening at a youth event, I watched a fighter step onto the scale with grey skin and dry lips. He missed weight, had to run another forty minutes, then returned and made weight. His bout took place six hours later. No doctor re-measured his hydration status before he stepped onto the mat.

I recorded the incident. I had no number to compare it against, and that is the most uncomfortable thing in this entire piece.

Regional Games and the pressure of diversity

At the regional event level, Vietnamese martial arts faces a specific pressure: the Games programme changes with the host country.

Each edition, the host proposes a list of sports and events, member nations negotiate, and the final list can differ entirely from the previous edition. For martial arts, this means an event can be medal-bearing one edition and vanish the next.

The consequence is that federations must optimise for a target that may disappear. They must train athletes for events they are not certain will have a stage. They must allocate budgets to groups that could be cut from the programme at any moment.

This is one reason long-term investment in data becomes hard to justify. If an event might vanish in two years, why build a data system for it?

My answer is: precisely because it might vanish. If an event disappears from the regional Games, it still needs to exist domestically. And it can only exist if someone understands it. And people can only understand it if there is data to understand.

Between the early 2010s and the mid-2020s, vovinam went through at least one absence from a regional Games, then returned, then remained on the waiting list for confirmation at subsequent editions. Each time, the entire training cycle for the sport had to be redesigned.

A good data system would help enormously in those moments. If you have ten years of athlete tracking data, you know who can still compete at the next edition. If you do not, you start again from a roster and trust the coach's assessment.

A coach's assessment has value. But it is a single data source. Building elite sport on a single data source is a risk.

The counterintuitive angle: specialisation cannot save a sport that has lost its data

Now the part I know will annoy people.

Inside Vietnamese sport there is a popular belief: to win medals, you must specialise. Pick one sport, one event, one athlete group, and pour everything in.

That belief is right in most cases. But it has a blind spot.

Specialisation only creates an advantage when there is a measurement system good enough to show whether you are improving or treading water. Without that system, specialisation simply means you have poured more resources into a direction you have no way to check.

In Vietnamese martial arts, many events have already reached considerable depth. National teams train year round. Athletes have individual nutrition and conditioning programmes. Coaches have international experience.

But the feedback mechanism still rests mainly on two sources: competition results, and the coach's eye.

Both are valuable. But both have high latency. Competition results arrive a few times a year. The coach's eye is accurate but cannot simultaneously track ten athletes across many months.

A data system fills that latency gap. It does not replace the coach. It gives the coach a tool to see changes the human eye cannot detect at daily frequency.

That is why I say the biggest problem in Vietnamese martial arts is not a shortage of talent. The talent is there. The problem is that the talent has no mirror.

The blind spot: nobody codes national-level bouts

There is one detail I always check when reporting at a national event. I ask whether anyone is sitting and coding the bouts.

At major international events, teams of specialists sit in the stands with laptops, logging every action under a standard coding system. That data is then sold to federations, broadcasters, and teams.

At most Vietnamese national events, the answer is no. Nobody is coding. Someone is filming. Someone is taking handwritten notes. Someone is shooting photographs. But nobody is turning what happens on the mat into a structured dataset.

The consequence is that each tournament ends and leaves behind very little that can be reused. A great bout may be retold in conversation for years, but there is no data to prove where its greatness lay.

In an industry where combat sports are gradually approaching international standards on rules and safety, the absence of bout coding is a gap that can be closed at very low cost. A team of three people with three laptops could code an entire national championship in four days.

But to do that, someone inside the organising committee has to believe it is worth doing.

The ring is a laboratory, mistakes are the variables

I approach martial arts in the language of someone running experiments, which is why I do not write about winning and losing.

A bout is a sequence of hypotheses tested in real time. A fighter bets that an opponent will react in a certain way. A landed punch is a positive result. A missed punch is a negative result. The coach in the corner reads those results and adjusts tactics for the next round.

This is a scientific process conducted under enormous pressure, with feedback measured in seconds, and with real injury as the consequence.

What disappoints me is not that fighters make mistakes. Mistakes are an inevitable part of the process. What disappoints me is that those mistakes are not recorded.

A fighter makes the same error at three different events across two years, and no record shows it. A coach adjusts tactics between rounds and turns a fight around, and no record captures the adjustment.

We are running a continuously operating laboratory and storing none of its measurements.

A cross-discipline comparison

I want to place martial arts beside a sport I know better: athletics.

In athletics, data is not an option. It is the rule of the game. Time is measured in hundredths of a second. Distance is measured in centimetres. Wind is measured to determine whether a record is valid. A record is only ratified when the measurement conditions are complete.

In martial arts, there is no equivalent unit. There is no single measurement applicable to every bout and every discipline.

But that does not mean martial arts cannot be measured. It only means martial arts needs many kinds of measurement, and people who know which kind to use for which purpose.

For combat, the measurements are strike counts, accuracy, control time, and round-by-round conditioning indicators. For forms, the measurements are component scores by criteria group, plus technical indicators such as centre-of-gravity stability, hold time on difficult poses, and number of balance losses.

These two measurement sets cannot be compared directly. And that is precisely why collapsing them under one label is a methodological error.

Home matters, scorecards matter

I have an observation about how Vietnamese audiences follow martial arts, and it differs from what I am used to in Europe.

Here, audiences remember fighters' names extremely well. They remember hometowns, gyms, coaches. They remember bouts from many years ago with astonishing detail. At a talk at a martial arts club in Binh Duong, an older man recounted a bout held in another province nearly twenty years earlier, describing each round, each strike, and even the weather that night.

I asked whether he trusted that memory. He said yes, because he was sitting in the third row.

This kind of memory is a cultural asset. It is also a data problem. Personal memory cannot be verified, cannot be compared, and disappears when the person who holds it disappears.

This is why I do not see building a data system as a dry technical act. I see it as an act of preservation. Every number recorded is a fragment of memory that cannot be lost.

On my own direct observation experience

Based on my experience watching bouts from 2026 to now, I can say one thing about the difference between tournaments.

At events with good data, the atmosphere in the press room is entirely different. People argue about numbers. Someone offers a figure, someone else cross-checks, and the argument reaches a provisional conclusion within ten minutes.

At events without data, the argument shifts to memory and feeling. Someone says fighter A is stronger. Someone else says fighter B is faster. Nobody has anything to prove it with, and the argument runs forever.

The interesting part is that the fighters in both cases are very similar. Only the observation environment differs.

That is why I say the quality of Vietnamese martial arts is not decided on the mat. It is decided at the desk.

A punch at lazy reporting

I want to end the analysis section with an observation about laziness in coverage.

There is a very common template in Vietnamese sports journalism. An athlete wins a medal, and the article recounts a journey from poverty to glory. It is easy to write, easy to read, easy to share.

But that template skips the most important question: technically, what is this athlete good at, and how was that strength built over years?

Answering that requires data. Without data, the writer must choose between two options: write about circumstances, or write about the audience's emotions.

Both are legitimate. But neither helps the reader understand the sport.

I have fallen into this trap many times. Pressed by deadlines, I have written pieces based on circumstances rather than technique. I do not delete them. I treat them as part of the learning process.

Back to two screens

Back to that May evening in Bac Tu Liem.

After the two golds were awarded, I went down to the interview area. With the combat athlete, I asked about the second round, when he changed his movement pattern. He answered very specifically about distance and striking angles.

With the forms team, I asked about the scores. The coach said he knew the routine had been well marked but did not know exactly where the points had been lost. He added that if he had the detailed card, he would know what to fix for next year's event.

That sentence stayed with me longer than any number that night.

A coach training inside a system he cannot see. An athlete competing in a sport where her result exists only as a total.

And a sporting nation calling two different things by the same name.

What if

I do not want to end with a forecast. I want to end with a hypothetical, because that is how I test hypotheses.

Suppose next season, every Vietnamese martial arts federation is given three very simple tasks.

Task one: store every scorecard from every national-level bout, in digital form, in a single file per season.

Task two: measure and store height, weight, and weigh-in timing for every athlete at every event, separated by discipline.

Task three: record the number of recovery days for every athlete after every combat bout.

No expensive equipment needed. No complex software. Just a spreadsheet and one responsible person.

After three years, we would have something we do not have now: a baseline.

And once there is a baseline, people start asking better questions.

In combat, the question becomes: why is injury rate in one weight class markedly higher than others. Three years of data is enough to see that pattern.

In forms, the question becomes: why does the same routine at the same difficulty lose points differently across editions. Three years of judges' data is enough to detect the trend.

At management level, the question becomes: is resource allocation following past medals or measurable potential. Three years of athlete development data is enough to answer.

Without data, none of these three questions can be answered with anything other than opinion.

On the silence of the arena

There is an image I keep from many years of reporting.

It is the moment before a forms routine begins. The arena goes quiet. The athlete stands in the centre, hands together, exhales once. For about three seconds, the whole hall holds no sound but the air conditioning.

I once wrote a line about that moment in an article years ago: an empty stadium taught me that passion does not need a seat.

But later I reconsidered. That silence also taught me something else about data.

When the arena is silent, nothing is recorded. There is no shout to cross-check. There is no crowd reaction to measure. There is only one movement and one judging panel, and afterwards a number.

If we do not record that number in detail, the silent moment exists only in the memory of those present. And the number of those present falls every year.

On picking sides

People often ask me which side I am on: combat or forms.

I am on no side. I am on the side of whoever has data.

In an argument without numbers, the loudest person wins. In an argument with numbers, the person with the better reasoning wins. And in most cases, the person with the better reasoning is not the loudest.

That is why I spend time on things colleagues find boring: cross-checking scorecards, verifying head-to-head records, logging actual bout duration, looking up each federation's weigh-in rules.

None of that generates headlines. But it generates the foundation that makes headlines mean something.

On not apologising

Throughout my career I have been reminded many times that I am a woman writing about martial arts.

In 2026, when I proposed a change to a young track athlete's starting technique based on slow-motion data, a veteran coach laughed loudly and said women do not understand biomechanics. Six months later, that athlete broke a national youth record.

I tell this story not to claim a personal victory. I tell it because it connects directly to martial arts.

In Vietnamese martial arts, certain groups of athletes and certain events are treated as less important. Forms are often treated as a side programme of a combat tournament. Women's events in certain weight classes often have fewer bouts. Youth events are often not fully documented.

Those biases are not erased by statements. They are erased by data. When you have enough numbers to show that forms draw comparable audiences, or that women's weight classes have equal competitive density, the argument ends on its own.

This is why I do not apologise for asking hard questions. Data points to talent, but the heart points to champions. And the heart cannot be measured by a scorecard — but the scorecard is the only thing we have to start with.

A lesson from an unrelated mistake

I have said I do not delete my work when criticised.

That is true, but it does not mean I am never wrong. It means I let mistakes stay and turn them into part of the method.

In martial arts, this has a very concrete application.

Many people in the industry fear publishing data because they worry it will reveal weakness. A federation publishing an injury report might be read as admitting a safety problem. A coach publishing a student's failure data might be read as admitting incompetence.

But that way of thinking reverses causation. The safety problem exists whether or not there is a report. The weakness exists whether or not there is data. Publication only makes the problem solvable.

A recorded mistake is a fixable mistake. An unrecorded mistake is a mistake that will repeat.

On writing fast and writing right

I have a habit of writing fast, and that habit has its origins in a difficult year.

In 2026, when competitions were suspended, I lost most of my field work. I launched several projects at once to find a new direction, and only one survived. The lesson I drew was not to avoid multiple projects. The lesson was: finish one piece before opening a new experiment.

In martial arts, this principle applies directly to federations. A federation chasing too many events at once will not have the resources to finish any of them. A federation that picks a few events and builds data systems for them will have a foundation to expand later.

That is the kind of thinking I want to see at sports management level.

On the people working in silence

I want to give this section to the people I meet while reporting and never write about.

They are the referees sitting by hand in a hot hall, filing their cards afterwards with nobody reading them. They are the provincial coaches keeping their students' weight records in a school exercise book. They are the sports doctors making decisions about a fighter on intuition because there is no file in their hands.

These people are doing data work without calling it data work. They are doing the right job, with the wrong tools, inside a system not designed to recognise what they do.

If there is one reform worth making in the next ten years, I think it lies here. Not in buying new equipment. But in giving the people already keeping records somewhere to submit them, and a reason to keep going.

A small test

Here is a test I suggest to anyone interested in Vietnamese martial arts.

Pick a fighter you like. Try to find three pieces of information: the number of official bouts in their career, the number of rounds fought, and the number of injuries that forced time out.

For most Vietnamese national-level athletes, you will find the first approximately, the second vaguely, and the third not at all.

That is the current state of things.

And here is what I want to say: that state is not destiny. It is just a starting point that has not been updated.

The rhythm of organised chaos

In combat sports there is one thing data has not yet measured, and I think it never fully will: rhythm.

A good fighter can change the tempo of a bout without changing technique. He moves less, but moves at the right moment. He throws fewer strikes, but throws them at moments that destabilise his opponent psychologically. On the statistics sheet he looks less active. On the mat he is controlling everything.

This is the limit of data, and I want to be clear that I know the limit exists.

Data does not replace watching live. Data does not replace the eye of a coach with thirty years of experience. Data does one thing only: it keeps an argument from being steered by the most confident voices in the room.

From the running track to the keyboard, I found the rhythm of organised chaos. Martial arts has that rhythm too. We just have not found a way to record it.

On what I am not sure about

I am not sure whether building a data system would win Vietnamese martial arts more medals.

I am not sure whether federations are ready to publish detailed scorecards.

I am not sure whether a sixteen-year-old athlete in a distant province will be able to access data about themselves within five years.

There is much I am not sure about. But one thing I am sure of: every year that passes without data, we lose a piece of our own history.

And the history of Vietnamese martial arts is longer than any medal table.

My mistake

In this piece I used many figures from event records I cross-checked myself, and in some places I had to express things as estimates because official sources do not exist in public form. That is my mistake — for not having built a good enough database over the past eight years, when I could easily have started sooner.

If you read this and you hold an old scorecard, a weight-tracking sheet, or a coach's notebook, contact me. Those pieces of paper matter more than you think.
