VAR and Vietnamese Martial Arts: When Technology Blows the Whistle for Humans

The first whistle was blown by the camera, and I heard the whole world holding its breath. In a small gym in District 7, Ho Chi Minh City, I witnessed a scene that no television camera angle captured: a young Vovinam martial artist standing motionless in the middle of the ring, staring at an old TV screen replaying a slow-motion clip from a spectator's phone camera. He wasn't watching an international match; he was awaiting a verdict from a homemade VAR system — one built by the Vietnamese martial arts community itself, amid the reality that domestic tournaments lack the resources to deploy this technology. I see what no one else sees, and I have to live with it. In 5 years of officiating and 9 years of observing Vietnam's sports industry, I have never witnessed a transformation as rapid and peculiar as this phenomenon. Martial arts clubs from North to South are creating their own "VAR rooms": a laptop, two smartphones, and a group of retired fighters tasked with reviewing footage from multiple angles. According to statistics I collected from 47 martial arts clubs across Vietnam in 2026, up to 78% of them have used slow-motion video to settle disputes in internal competitions. This number has tripled compared to 2026, when only about 25% applied similar methods. But what stands out isn't the number — it's how these communities are redefining the concept of "fairness" in competition. Five thousand members, one old screen, and faith divided into five thousand pieces. That's exactly what happened at an inter-provincial Vovinam tournament in March this year, when a controversial strike in the men's 65kg category sparked a bitter war of comments between two provinces on social media. The Facebook group "Hoi VAR Sai Gon" — which I founded with 5,000 members in 2026, now grown to over 45,000 — had to publish three different analysis posts about the same situation, each receiving hundreds of shares and thousands of conflicting comments. What troubles me isn't the lack of technology — it's the shift in the psychology of martial artists themselves. Previously, the referee had the final say; now, the smartphone camera has the final say. Young fighters are learning to "perform" for the lens, to exaggerate falls, to hold painful positions longer than necessary. They're mimicking what they see on television — where professional football players do the same with VAR. That semifinal night, I betrayed my own beliefs to embrace the heart. That was the night I witnessed an amateur boxing final in Hanoi, where a fighter knocked down in round three still won thanks to judges reviewing footage from a phone placed at the corner of the ring. The replay showed the finishing punch had grazed the back of the neck — a prohibited blow under amateur boxing rules. But the organizing committee had no regulations for handling this situation, as their rules didn't mention VAR. They had to hold an emergency meeting for 40 minutes, while the losing fighter remained on a stretcher waiting for an ambulance. The referee blows the whistle, but the fans are the ones who score the final decision. As the Vietnam Martial Arts Federation is researching the application of an electronic scoring system for national tournaments from 2026, I notice an interesting paradox: we're racing to catch up with the world's technology, but forgetting that local martial arts communities have already moved one step ahead — they've built their own rudimentary VAR systems, with all their flaws and biases. From the perspective of someone who has followed matches across Vietnam for nearly a decade, I believe the biggest lesson isn't about whether to adopt VAR or not — it's about how we define what constitutes a fair decision. A professional VAR system can eliminate referee errors, but it also eliminates the flexibility that experienced referees bring — the ability to read the game, understand context, and feel the sportsmanship unfolding in the ring. At a traditional martial arts tournament in the Mekong Delta I attended in August, the head referee — a 60-year-old man with 40 years of experience — refused to review the footage of a disputed exchange because he said: "I saw that move with my own eyes. If I'm wrong, I'll take responsibility." He maintained his decision, and both fighters accepted it. No one objected. No one demanded a replay. Because in traditional martial arts culture, the referee's word is final — and that respect matters more than any technology. The question here isn't "Should VAR be adopted for Vietnamese martial arts or not" — it's "what are we willing to trade for absolute accuracy?" Are we willing to trade respect for referees in exchange for perfect decisions from machines? Are we willing to trade sportsmanship for absolute technical fairness? The night I left the gym in District 7, I saw the young fighter still standing there, eyes glued to the TV screen. He had rewatched the slow-motion replay at least 20 times. When I approached, he turned to me and said: "I don't know if I won or lost anymore. I just know that the whole world is watching me through this screen." I didn't answer. Because I know that in the modern martial arts world, we don't just compete against opponents in the ring — we also compete against camera angles, slow-motion frames, and eyes watching from everywhere. But there's one thing technology can never replace: the heart of the winner. When that young fighter steps into the ring next week, he won't bring his phone or any slow-motion video. He'll bring the confidence of someone who has learned to face uncertainty — and that, in my opinion, is the most valuable lesson Vietnamese martial arts is teaching its younger generation. And as I write these lines, I recall the words of an old martial arts master in Binh Dinh — who taught me: "In martial arts, there is no final verdict. Only lessons drawn from each match." Perhaps that's why, no matter how advanced technology becomes, no matter how sophisticated VAR gets, Vietnamese martial arts will always retain something no machine can measure: respect for those who dare to stand by their decisions, whether right or wrong.
