Vietnamese Martial Arts Between Two Untranslatable Measuring Sticks

Every sports story begins with a forgotten number. This time, that number is not on the scorecard of any particular fight. It lives in the gap between two ways of measuring a kick: one counts the strikes that land over three rounds, the other records the difficulty and precision of a movement within a form. The same motion of the human body, two measurement systems, and the result is two stories that have almost nothing to do with each other. For months, I watched two stages that seemed to belong to two different centuries. On one side were the fight nights of domestic professional mixed martial arts promotions, where every punch is logged by software, every takedown converted into a percentage, and every fighter enters the cage with a fully digitized profile. On the other side were traditional martial arts competitions, where a panel of judges sits in a row, pens in hand, scoring each movement of a form on a scale that outsiders struggle to interpret. These two worlds meet at exactly one point: both believe they are accurately measuring the value of a person on the mat. And both are wrong in different ways. To see why this gap matters, we need to look at the context of Vietnamese martial arts over the past decade. After professional MMA promotions began to emerge domestically, a generation of young fighters grew up with a new language: efficiency, conditioning, finish rate, strikes landed per minute. They no longer train within the closed curriculum of a single school, but in multi-discipline programs with strength coaches, nutritionists, and pre-fight video analysis sessions. At the same time, traditional Vietnamese martial arts have kept a separate standing, in schools, in local federations, and in regional multi-sport games. There, a fighter's value is not how many fights he has won, but how much difficulty, precision, and spirit of the school he brings to a form. Vovinam, founded by Nguyễn Lộc in 2026, is the clearest example of this current, existing both as cultural heritage and as an international competition discipline in forms and sparring. These two systems are rarely placed side by side for comparison. But when they are, they expose a problem few want to face directly: whose ruler are we using to measure martial arts, and to what end? When everyone looks at the victory, I look for where they hide the weakness. Here, the weakness is not in any individual fighter, but in the toolkit itself. Start with the metrics a professional MMA promotion uses. Strikes landed per minute indicates offensive frequency. Strikes absorbed per minute indicates defensive capability. Takedown defense rate indicates grappling foundation. Finish rate indicates the ability to end a fight early. Those four numbers, added together, draw a portrait. But that portrait is only valid when the fight takes place under a fixed rule set, with fixed duration, and against an opponent in the same weight class. Step outside that framework and the four numbers lose nearly all meaning. A fighter may have a very high takedown defense rate, but if the rules allow grabbing the gi, striking prohibited zones, or unlimited fight time, that number says nothing about his real-combat ability. On the other side, the traditional martial arts scoring system has its own metrics, except they are rarely written down as formulas. The difficulty of the movement, the precision of the posture, the rhythm, the balance, and even the spirit are all evaluated, but by the human eye. That is both a strength and a fatal weakness. The strength is that it captures what a camera cannot. The weakness is that it cannot be reproduced: two different judging panels can give the same form two different scores, and no one is wrong. This is where I must state clearly what I believe. I believe in data, but I write about what data cannot measure. A kick in the cage can be recorded by ten parameters. A kick in a form can be recorded by none. But both are the result of thousands of hours of training, and both can fail because of a single moment of lost focus that no software detects. There is one intersection few notice: both systems have blind spots they do not want to measure. In MMA, that is the weight cut. A fighter can step on the scale with a beautiful number, then in the next twenty-four hours rehydrate five or six kilograms to enter the fight. The number on the scale lies, but no one wants to say so, because that number is part of the event. The fighter's real body, the body that must absorb strikes over three rounds, never appears on any stat sheet. In traditional martial arts, the blind spot lies elsewhere. A fighter can perform a perfect form, but no one can verify whether he can apply those movements in a real confrontation. The form is a closed language, beautiful in itself, but it promises nothing about fighting ability. And because no one measures it, no one is accountable for the gap. When the stadium is empty, the person inside finally speaks. I once stayed behind in an arena almost emptied of spectators, after all the night's fights had ended, and watched a young fighter slowly unwrap his hand wraps. His fight had ended in a loss that the stat sheet recorded as a decision defeat. But the way he unwound each loop, folded it, set it on the chair, and then sat silently staring at the empty mat, that is something in no report. No metric can measure the moment a person understands he has just lost something. Now to the counterintuitive part. There is a popular view that traditional martial arts must be modernized by applying sports metrics, that without data the art will die. I do not believe that, at least not entirely. The problem with applying one measurement system to another is not whether the new system is good or bad. It is that you measure what you have chosen to measure, then assume you have measured everything. A form scored by motion-recognition software will produce very beautiful numbers. But those numbers will skip exactly what makes the form: the meaning of each movement within the school's tradition, and the link between that movement and a specific combat situation the previous generation envisioned. Conversely, applying the eye of a traditional judging panel to an MMA fight is equally meaningless. No one scores the spirit of a choke. No one awards rhythm points for a liver hook. These two systems cannot replace each other, and should not try. The blind spot of both systems is the same type: both measure what is easy to measure and leave the hard things untouched. MMA easily measures offense and defense, but struggles to measure will and fear. Traditional martial arts easily measure movement, but struggle to measure real-combat effectiveness. Both are running from the same question: do we actually want to know the truth about a person on the mat, or do we just want a number to feel safe? Seen broadly, this is not just a story about two martial arts. It is the story of an entire sporting world learning to live with data. Domestic MMA promotions are building ranking systems, exclusive contracts, and events designed to sell tickets. Traditional martial arts federations are trying to bring their disciplines into multi-sport games, where medals are counted, and a gold medal is sometimes worth more than a decade of preserving tradition. Between those two worlds are young fighters. They train traditional martial arts from childhood, then grow up drawn toward competitions with prize money, television, and contracts. Many do both, carrying within them two measurement languages that cannot be translated into each other. When they compete, they fight not only an opponent, but also the expectations of two different communities, each demanding its own kind of success. Behind every loss is a decision that was ignored. And behind every beautiful number on a stat sheet is usually another decision, quieter: the decision not to measure something, because measuring it would be more complex, more expensive, or harder to sell tickets for. There is one aspect both systems handle equally badly: the long-term health of fighters. In MMA, a fighter can accumulate thousands of blows to the head across a career, and no metric tracks those blows over time. Research on brain injury in combat athletes has existed for a long time, but it rarely appears in contracts, in promotion rules, or in pre-fight press conferences. In traditional martial arts, the problem is different but no lighter. A fighter can train movements that demand joint and spinal tolerance for years, and when the body degrades, no system records it. There is no injury rate tracked, no retirement fund, no career-transition program. Both worlds talk about respecting fighters. But real respect is not in the applause after a fight or a form, it is in whether you follow how people are doing after the lights go out. I am not writing this to conclude which system is right or wrong. I am writing to pose a question I still cannot answer: if we cannot measure martial arts with a common ruler, should we keep trying? Perhaps the answer is not choosing one system, but accepting we must live with both, honestly. Fans remember the score, I remember the expression of the loser in the final second. Data tells us who won, but it does not tell us why a person keeps stepping onto the mat after losing too many times. Breaking convention does not require a loud voice, it requires evidence heavy enough. But there are also truths that only appear when we are patient enough not to measure them. Sports, in the end, is a common language of humanity, and every language has words that cannot be translated. The job of a writer like me is not to translate them neatly, but to keep them intact. When the two rulers of Vietnamese martial arts cannot translate into each other, the worry is not that we lack a common ruler, but that we are rushing to pick one and forgetting what the other once saw.
