Blank N/A records and the silent pain in Vietnamese sport: When we do not measure, athletes pay the price

I once received a ten-page injury analysis report. The sender attached a note: “The club does not store data.” Every table cell said N/A. No player name, no injury history, no minutes played, no training load. An average person would call that garbage. I call it a mirror reflecting an entire system. Data never lies; only our reading can be wrong. An empty N/A cell is still an answer. I am not writing this to blame any specific club. I want to talk about a chronic disease in Vietnamese sport: we still manage athletes by emotion, by a coach’s gut feeling, by the pressure to win, but not by data. When data is absent, we blame the body. The player is weak, the player is immature, the player lacks willpower. After more than thirteen years of watching sport, I have learned that blame never saves anyone. I found the hole not in the player’s body but in the way we measure it. In 2026, as a student intern at the Paris FC youth academy, I saw a young midfielder suffer three hamstring problems in fourteen matches. The staff kept playing him, partly because he looked fast in training. I looked at his file and realized no one had tracked his training load, no one had recorded the imbalance between his two legs. I built a simple chart of injury frequency against training intensity and warned that his risk of muscle tear was near 87 percent if he continued. The coach reluctantly gave him one week off. The player avoided a major injury and scored twice in the next three matches. That story is not an exception; it is the rule. From Paris to Hanoi, the real problem is not a lack of machines. It is the habit of treating data as a luxury. At the 2026 World Cup, Germany’s defense of the title collapsed in the group stage. Many blamed coach Joachim Löw and tactics. I saw a different warning. Mesut Özil started all three matches while carrying an achilles and hamstring problem. His distance covered was about 68 percent of his previous Arsenal season. A creative hub without mobility, pushed into the most competitive tournament on earth, soon lost control of midfield. Germany’s story is a lesson for Vietnamese football today. When a big tournament approaches, teams suddenly raise training intensity. Players run more, fight more, but nobody asks how much load they accumulated in the previous months. In many V-League clubs, medical staff write notes on paper, enter late, or do not enter at all. Young players are forced to play three weeks without rest because coaches believe playing more equals improving. Human bodies do not work that way. Injury is never a single random moment; it is the peak of a series of measurement failures. Modern football often praises distance covered and sprint counts. Clubs spend large sums on GPS vests and analytics software. But useless running also creates beautiful numbers. A player may run twelve kilometers in a match; if nine of those are harmless running, the number only reports fatigue, not value. When we measure the wrong thing, we reward the wrong behavior. A risk model does not save anybody; it only tells us where to look. We need electronic health records for every professional player. We need to track match days, minutes, workload, sleep, pain, range of motion, and muscle balance. This does not require million-dollar technology. A smartphone and a Google Sheet are enough if someone is responsible for entering data. The issue is not technology; it is culture. If a team does not start measuring today, twenty years from now they will still be calling injuries bad luck. No, it is the cost of not measuring. I have made my own mistakes. I have given predictions that were wrong. Every time, I learned that the data was not lying; my reading was. That is why I speak with humility. A strong body is not accidental. It is created by correct decisions, honest numbers, patience, and respect for science. The final question is not just for coaches or doctors. It is for everyone who loves sport: Are we ready to listen to an athlete’s body instead of only listening to their results? If we are not ready, we can say so clearly. Change only begins when we admit that the N/A cells are the real crisis.
