Vietnam's Combat Sports Lacks Record-Keeping, Not Fighters

At a fight night in a venue in the south of the city, the third round ended with a roundhouse kick to the temple. The stands rose as one, camera flashes raining down. Ten minutes later, while the fighter was still gasping on his corner stool, I asked his coach a single question: “Over the past eighteen months, how many times has he stepped on the scale, and how much did he cut each time?” He patted my shoulder, laughed, said “that's a hard question, son,” and turned back to take a keepsake photo with his student.

That question left a hole behind. Nobody is hiding the data; it simply has never been recorded. Fans remember the scoreline. I remember the fighter's expression at the fortieth second of the third round — the way his knees dipped half a beat every time he was pushed into the ropes. That is the one thing machines cannot measure, and the only thing a combat sport without record books still manages to keep.

Vietnam has a deep martial arts base. Vovinam, traditional martial arts, boxing, Muay Thai, and more recently MMA — each discipline has its own events, belts and a gym network stretching from Hanoi and Da Nang to Saigon and the delta provinces. The number of young fighters training at these centres has risen steadily for years. Names such as Nguyen Tran Duy Nhat on the international Muay Thai circuit, or Nguyen Thi Thu Nhi, who once laid hands on a world title belt from a major boxing sanctioning body, show that human resources are not the shortage. Record-keeping infrastructure is.

In Japan, where I work, every professional boxing bout passes through a commission obliged to publish official weigh-in figures, scoring results, disciplinary rulings and each fighter's bout history. Kickboxing and grappling promotions run their own databases, updated event by event. As a result, someone sitting in Tokyo can still look up how much weight a given fighter cut before each bout over two years, how long he rested after an injury, how many fights he won in the third round. In Vietnam, the same information is scattered across coaches' memories, cameramen's phones, and a handful of articles that long ago fell off the front page.

The gap between a mature combat sport and a growing one is not the number of fighters. It is the number of data columns filled in consistently.

Technical and tactical analysis is the first layer, and the easiest to be fooled by. To say anything about a fight you need numbers: strike rate per minute, significant strike accuracy, defensive efficiency, finishing rate inside the time limit. At major promotions those metrics are logged automatically and published after each round. At domestic shows they exist as the memory of whoever sat closest to the ring. Without numbers, every claim about a “style” is a dressed-up guess. When people look at the victory, I look for where the weakness is hidden — and the weakness usually appears in the third round, once the breathing rhythm has changed.

Condition is not measured in age. A twenty-eight-year-old fighter may have thirty bouts behind him, or eighty, plus hundreds of kilos cut in total on weigh-in days and three long layoffs for knee injuries. Those two bodies do not belong to the same profession. In Vietnam, nobody has compiled that sequence of data — not even the fighter himself. I have asked more than ten people how many times they cut more than six kilos in a single week. Only two remembered vaguely, and both were guessing.

The organisational context shapes a career more than any opponent. Long exclusive contracts, belts fragmented across multiple bodies, cross-promotional bouts, schedules packed tight for broadcast reasons — all of it decides whether a fighter moves fast or slow. A talented fighter locked into a three-year deal on low pay will fall behind a lesser one who is released onto the international circuit early. In Japan these clauses are tracked by the press routinely. In Vietnam they sit almost entirely outside public view.

Money is the least discussed layer. Broadcast rights revenue, gate revenue, fighter pay, sponsorship value — these four columns determine the health of an entire discipline. When pay is never disclosed, evaluating a career becomes a maths problem with missing variables. Fans see the fighter standing in the ring; they do not see how many months of a coach's salary, how much gym rent, how many bills come due after retirement.

Rules and governance get the least airtime, and they are the most dangerous layer when left empty. Scoring, drug testing, weigh-in procedure, disciplinary rulings — that is the skeleton of a serious combat sport. An opaque scoring system produces champions nobody can verify, and unverifiable champions drag down the commercial value of the whole promotion. The good news is that this is also the cheapest layer to fix, because it needs regulation, not big money.

Fighter health is the layer I watch most closely after every shoot. Brain injury, rapid weight cutting, post-retirement welfare, mental health — these four risk groups do not distinguish between famous fighters and unknowns. When the stadium is empty, the person inside finally speaks. During a project interviewing fighters who competed without crowds, what kept me in the room longest was not winning or losing, but hearing a twenty-five-year-old describe preparing mentally for difficulty walking at forty.

Media narrative and market expectation run on their own cycle. A fighter who wins three in a row gets pushed as a phenomenon. By the fourth fight, a loss, the same people who pushed him are the first to turn away. The distance between expectation and reality can only be measured with data, and only if that data exists.

The industry's transmission chain runs long: from gyms and talent pipelines, through broadcast and digital platforms, through data and betting, through equipment and consumer spending, and finally into policy and regional development. A break at any link slows everything downstream. In Vietnam the clearest break sits right in the middle: with no data, broadcasters have nothing to analyse, sponsors have nothing to measure, and fighters have nothing to bargain with.

I trust data, but I write about what data cannot measure. The two are not in conflict. Bad data makes people believe wrong conclusions; good data makes people aware of what they are overlooking.

A common misunderstanding circulates among domestic combat sports followers: that the biggest problem is the argument between traditional martial arts and MMA, or between strikers and grapplers. Those arguments are fun, but they are mostly decorative. They are easy because they are free, and they give participants the feeling of analysis while they are really just picking sides.

The hard questions sit elsewhere: who pays the fighter at the end of the month, who supervises the scale, who is accountable when a twenty-five-year-old cuts seven kilos in four days to make weight, and who records those cuts so that ten years from now someone can look back.

In Japan, those questions have answers written down in documents. In Vietnam, they usually end with a “that's a hard question, son” and a group photo. The distance between the two combat sports cultures is not talent. It is the habit of writing things down.

A complete record book does not make anyone stronger in the ring. It only lets the people outside the ring see who is weakening before it is too late. Breaking convention does not require a loud voice; it requires evidence heavy enough — and evidence has to be recorded from the very first fight.
