Vietnamese Martial Arts and the Data Gap After Every Fight

On the evening of July 14, 2026, at the Khanh Hoa Provincial Sports Arena in Nha Trang, I sat in the fourth row with my lined notebook open on my lap. The fight ended after three rounds; the referee raised the home fighter's hand. The lights stayed on, the crowd rose to applaud, the winner lifted both arms to the sky. I bent down and wrote one line: "Fight over. No detailed scorecards. The scoring scale of the three judges is unclear. The organizers have not released any statistics." Then I sat still, staring at the blank space beneath that line. I have seen this scene too many times in more than forty years of watching Vietnamese martial arts: after a fighter's greatest moment, what remains is memory, not numbers. Every season has its own heartbeat, if only you take the trouble to listen, but that heartbeat must be recorded before it fades. Team sports in Vietnam have built a degree of data infrastructure. A V.League football match has passes, tackles, and distance covered for every player. A basketball game has points, fouls, and substitutions. Martial arts is different. A single evening card can feature eight fights, three rounds each, and by dawn almost no one has preserved a single figure beyond the final result. No statistics on strikes landed, no success rate on defense, no round-by-round conditioning data. Fans go home with emotions; a writer like me goes home with a notebook only half full. The causes lie on many sides. Vietnamese martial arts operates mainly on short tournaments, limited budgets, and amateur judging crews. A provincial organizer can erect a ring and invite referees, but has no one seated beside each corner recording data. I once asked a coach in Nha Trang why he did not keep statistics for his students' fights. He laughed and said: "Why bother writing it down, everyone knows who won or lost." But that "everyone knows" exists only in the memory of insiders, and memory fades with the years, while public opinion does not. I still remember another evening, around 2026, at an open tournament in central Vietnam. A young fighter from Khanh Hoa won three fights in a row. Local media reported he was "undefeated." But when I flipped back through my notebook, I found he had lost a fight in a youth tournament two years earlier, only that loss was never reported and never recorded anywhere. So an "undefeated" record was born, not because he won everything, but because no one wrote down the time he lost. This is the familiar trap of Vietnamese martial arts: records are created by silence, not by the ring. In the international analysis community, every fighter comes with a data sheet. Fights, wins, losses, knockout rate, times knocked down. Major platforms even track significant strikes, output per round, and the point at which a fighter begins to fade. Thanks to that, a punch can be analyzed not just by feeling but by numbers. In Vietnam, we lack almost all of that foundation. Fighters who reach the international stage, such as Truong Dinh Hoang, have relatively complete competitive records, but these are rare exceptions. I do not say this to criticize anyone. I say it because I have sat through too many evenings, watched too many good fighters, and then witnessed their talent forgotten simply because no one recorded enough. The deeper problem lies in how we treat data. In many places, martial arts data is treated as the property of the organizers, not the community. No one publishes it, no one shares it, and fans are forced to trust numbers passed on by word of mouth. When a fighter changes circuits, their record vanishes and restarts from zero. When a coach retires, his store of experience leaves with him, with not a single record left behind. This problem goes beyond technique and touches culture. We are used to trusting our eyes more than documents, and in martial arts, the human eye often misremembers. The consequences of this gap do not stop at journalism. Without data, federations struggle to rank fighters, struggle to select athletes for international competition, and struggle to convince sponsors to invest. One sponsor once told me they were ready to invest in martial arts, but needed to see numbers: how many fighters, how many fights a year, how many spectators. We have no answer to the simplest questions. Based on my experience watching fights over more than four decades, I believe this is the greatest bottleneck in Vietnamese martial arts, bigger even than the funding problem. There is one thing I learned after my stumble in St. Petersburg in 2026, when I mispronounced a player's name and was criticized by viewers. I sat up all night, checking every name, every number. Since then, I have understood that accuracy is a debt owed to the reader. With Vietnamese martial arts, that debt is even greater: we are losing the data of an entire generation of fighters. People remember goals, I remember the sigh behind the goal, and in martial arts, I also remember the numbers that were never recorded. Some say martial arts is about emotion, that numbers are not needed. I do not entirely agree, but I understand why people think so. A beautifully landed kick is finer than any spreadsheet. But without numbers, we cannot distinguish a lucky fighter from a durable one, cannot tell who wins through technique and who wins through conditioning. Without data, every argument about martial arts ends in "that's how I saw it" and "that's how I saw it too." When the argument stops there, the credibility of the whole martial arts community stops there as well. I do not wish Vietnamese martial arts to become a spreadsheet. I only hope there is someone, at every tournament, who sits down after the lights go out and records what happened. A small notebook, an open data file, a library of fights gone by. I write slowly because I want to remember for a long time, like a person keeping the rhythm for the whole arena. Perhaps Vietnamese martial arts also needs such a rhythm-keeper, someone who sits beside the ring and records every strike, every round, every quiet moment. The quiet stars of Nha Trang never go out, but if no one records their light, later generations will see only a blurred darkness. An empty arena, but I hear the applause of those who never give up, and I want that applause to be counted, kept, and remembered.
