When a Swimming Analysis Contains Only N/A: Lessons from Empty Data in Vietnamese Sports

A detailed analysis full of N/A markings has just reached my desk, accompanied by a note: “Stage 2 cannot be completed because Stage 1’s deconstruction contains no information.” The sender was a familiar sports partner. They wanted an expert response to a piece of writing about swimming. But when I opened the file, I found no swimmer’s name, no distance, no result, no technical numbers. Nine assessment sections were simply blank. My first feeling was not frustration. It was a familiar kind of loneliness. Eight years of swimming taught me a simple lesson: when you stand on the starting block without a stopwatch, without someone counting your stroke rate, you do not know whether you are fast or slow. You only know you are swimming. Vietnamese sport is currently an environment with an excess of emotion and a shortage of measurement. An empty analytical report is not a rare event. But it exposes a sickness within our sports culture: we prefer to celebrate victories rather than collect the data that tells us why the victory happened. In the article I received, the technical section was marked as impossible to assess. There was no data on stroke rhythm, breathing frequency, energy efficiency, or turn time. For a genuine swimmer, those numbers are more valuable than a medal. A 100-meter freestyle race lasts less than fifty seconds, but it contains thousands of micro-data points: the number of breaths, the angle of the hand entry, the underwater kicking distance, the turn depth. Without those numbers, any technical comment is no more than an impression. I cannot say whether an athlete is improving or declining, because the mirror reflecting his form has been covered with fog. The performance and result data section was no better. There was no world ranking, no exact time, no context comparing the athlete with national or Asian records. Someone sent me a sports analysis, but there was not a single number on which to build a development curve. In sports intelligence, we call this “a map without coordinates.” You can see the shape of the coastline, but you cannot tell where the ship is. I remember the 29th SEA Games in Kuala Lumpur in 2026. The Vietnamese swimming team had many young talents, but the local media focused only on gold medals. They rarely asked: what training program produced this result? Was the improvement due to a better stroke rhythm or stronger muscular endurance? Without answers, today’s success will become tomorrow’s accident. The analysis of the competition system was also empty. There was no event name, no pool conditions, no qualification rules, no placement on the Olympic cycle. Swimming is a sport of precision. One hundredth of a second can separate a medal from seventh place. But that level of precision only makes sense when we know the context. Swimming in a 25-meter pool is not the same as swimming in a 50-meter pool. Swimming at 1,500 meters above sea level is not the same as swimming near the coast. Without context, a time of 1 minute 58 seconds in a 200-meter individual medley means nothing. The section on the global swimming landscape also had only one line: impossible to construct a map. There was no country, no swimmer, no national team, no coaching transfer trend, no training-center movement. In a rapidly changing swimming world—where the United States, Australia, China, and Britain constantly update their coaching models—an analysis that cannot name a single national team is alarming. It reveals that our information sources are constrained by hearsay and transient emotions. We can easily learn that an athlete has won a medal, but it is far more difficult to learn which endurance program his coach is using. The most important part was the risk and governance section. The report found no risk, because it found nothing to scrutinize. But that is not a clean bill of health. In the sports betting analysis industry, we follow a principle: the absence of information does not mean the absence of risk; it simply means the risk is beyond our observation range. I have seen countless athletes who looked excellent on paper but failed on the starting block. The causes can be hidden in injuries, psychological pressure, or even in an inadequate anti-doping testing system. If our data infrastructure has no checking mechanism, we will never see these risks until after the crisis occurs. One detail made me pause the longest. In the section assessing the athlete’s career path, the report stated that there was no information about age, injury history, performance-development slope, or coaching environment. No human story was told. I thought about the young provincial swimmers I have met in Hai Phong. They train in pools without high-tech measurement equipment, without nutritionists, without sports physicians following their journey. They swim quietly, counting laps, hoping that a talent scout will one day notice them. But how can a scout notice them when no data has been recorded? Con số lên tiếng, nhưng không ai hỏi chúng đã khóc bao nhiêu lần. Many people will argue that a sports article does not need this much data; it only needs an emotional story. I have heard this argument many times, and I respect it. But when we avoid collecting data, we unintentionally create a distorted story. A medal-winning athlete might actually be exhausted after three years of uncontrolled training load. An athlete who fails at a major event might be in the middle of a promising technical transition. If we look only at medals, we will praise the wrong person and abandon the right one. Data is not the enemy of emotion; it is the guardian of fairness. I do not pray with bells; I pray with fragmented numbers every night. That is a sentence I often write in internal reports. When I analyze a swimmer, I need to see every turn, every breath, every lactate reading after training. Those numbers are like musical notes. If one note is missing, the entire symphony becomes distorted. But in Vietnam, we are missing far too many of those notes. Our training centers still rely mostly on personal experience. Talented coaches are forced to improvise. Athletes rarely receive scientific assessment using proper equipment. We expect medals that are far higher than our budget for sports science. An empty analytical report is not, in the end, a useless document. It is a precise mirror reflecting the state of our data culture. When we look at the mirror and see a blank space, we should not blame the mirror. We should ask: why is there nothing in this room to reflect? The answer lies in our data-collection processes, in the investment in sports science, in the way we train journalists and analysts, and in the way we confront truth. With the current level of confidence, I cannot say whether this data gap is a nationwide problem or a problem confined to a small group. But I know that unless we change soon, we will keep telling beautiful stories with false numbers. The final lesson I take from this N/A-filled report is not in the letters N/A. It is in the attitude of the people who produced it. They were brave enough to say that they did not yet have enough data to reach a conclusion. That is rarer than gold. But a good analytical system does not stop at saying “I do not know.” It must also know how to search for the answer. When we admit the gaps in Vietnamese sports data, we can begin to fill them. Every wrongly recorded split, every stroke not logged, every story about a swimmer not told with precise numbers, is part of a larger image we are currently distorting. An empty stadium is a strange marriage between data and loneliness. Inside this emptiness, I still see one spark of hope: a new generation of analysts is learning to say “not enough data” before accepting any hasty judgment.
