Vovinam and the incomplete analysis: Vietnam is losing the story behind every performance

On a drizzly afternoon in Hanoi, I sat at the back of a Vovinam club in Hoàng Mai district. Three athletes in white uniforms repeated a performance routine while their coach knelt and wrote in a worn notebook. When they stopped, all I could hear was a deep breath. An empty arena can be so silent that I can hear the breath of the match itself. That image reminded me of blank fields in a technical analysis: no video, no numbers, no athlete name, no conclusion. Many people think martial arts need feeling more than data, but for me, the absence of numbers is making Vietnamese martial arts lose a language. Vovinam, also known as Việt Võ Đạo, was founded by Nguyễn Lộc in 2026 in Hanoi. After more than eight decades, it has crossed borders and appeared in regional sport games and many countries across Asia and Europe. However, whenever I want to write a post-event analysis, I meet the same questions: where is the precision of a technique? Which indicators measure endurance? How can a Vovinam fighter’s striking ability be compared with international peers? There is almost no open system answering those questions. Imagine covering an Olympic event with no time sheet, no trajectory data, no information on step frequency for a 400-meter runner. I could only write: “the athlete runs fast”, “the curve is beautiful”, “the punch is strong”. Readers would not know how fast, how beautiful, how strong. Vietnamese martial arts are in that state. An analysis needs concrete facts, names, context and data. If those fields are empty, every judgment is just a passing emotion. I have spent twenty-four years watching sports from domestic to international stages. In performance disciplines like kata, taolu and martial routines, scores are formed from difficulty, execution, rhythm and martial spirit. But when I watch a youth Vovinam competition, I cannot find an explanation why one routine is rated higher than another. Coaches answer “clean techniques” or “good spirit”. Athletes only know whether they won or lost. Nobody talks about joint angles, extension, balance time or movement speed. That reflects a gap, not in athletes’ effort, but in the coaching and training system. Many Vovinam clubs still rely on oral experience. A good coach can see and correct with the eye, but when that person retires, the knowledge leaves. There is no standardised video, no numeric evaluation framework, no storage of each athlete’s competition history. Other sports have built data libraries for decades, while Vovinam remains a draft with blank spaces. People say we must polish raw gems, but I believe a gem already shines in the mud. To see that light, we need a magnifying glass. The magnifying glass of modern sport is data. I once sat for hours in a small meeting room in Incheon, watching South Korean colleagues analyse an Olympic runner’s stride. They looked not only at the ankle, but also at ground contact time, centre-of-mass deviation and cadence. Then they wrote their story. In Vietnam, for Vovinam, most of us are still outside that lens. Some argue traditional martial arts should not be distorted by machines and statistics. I disagree. Machines do not erase the essence of martial arts; they help us understand why a stance is stable, why a throwing technique is decisive. Data tells stories in another language: angles, time, force and rhythm. It does not replace a teacher’s intuition, but it preserves that intuition from fading. If today’s generation does not record what is happening in training, future generations will have nothing to compare. At forty, I no longer chase transfer news; I slow down to hear the story behind the numbers. I want to see a Vovinam athlete leave the mat with a medal, but I also want to see data from a sensor measuring an aerial kick. I want to read an analysis of a fighting final with statistics on effective attacks, reaction time and distance covered on the mat. That is how a pure Vietnamese martial art can integrate without losing identity. The incomplete analysis is not a verdict; it is an invitation. The blank fields in Vovinam’s data system can be filled by sports universities, federations and the coaches sitting in the corner of the training hall as I witnessed. The question is not whether this martial art is worth the investment, but whether we are humble enough to record small details before chasing big glory. Then the athlete’s breath after a performance will be, not just sound, but a poetic chapter in the data book of Vietnamese sport.
