Vietnam Swimming Beyond the Nguyen Thi Anh Vien Era: From Stopwatch to a Training Ecosystem

I still keep an old habit from my internship days in Nha Trang: before believing in a record, I time it myself. A stopwatch does not lie; it whispers. It whispers about an unfinished hand entry, about a half-breath swallowed at the end of a swim, about an athlete still waiting to wake up. Vietnamese swimming is entering a phase where those whispers matter more than celebrating a single outstanding individual. Nguyen Thi Anh Vien was a rare wonder for Vietnamese sports. From the 2026 SEA Games to the 2026 SEA Games, she built an impressive collection of medals and earned regional respect in middle-distance and distance events. But one number has stayed with me from that period: the number of Vietnamese swimmers who reached Olympic qualification standards could still be counted on one hand. We had a genius, yet the system around her was not built to produce the next generation of geniuses. Swimming is not a sport of luck. Breathing technique, propulsion efficiency, pace strategy, recovery capacity between heats and finals—all of those leave traces on the result board. During a national youth championship, I once counted something myself: many swimmers performed well in the first part of the 100-meter freestyle, then faded dramatically in the final 25 meters. That was not just a matter of fitness; it was a sign that their stroke rhythm had broken when fatigue set in. Watching the replay, I noticed their elbows dropped below the ideal line, reducing effective pull distance by about 15 percent. This technical flaw can be corrected, but only if we build a standard training curriculum at the grassroots level. We often talk about inviting foreign experts, yet the deeper issue is how we handle data. Vietnamese training centers do not lack dedicated coaches. What is missing is the habit of systematic measurement. Many national teams still evaluate fatigue through subjective feeling instead of lactate levels; many training sessions repeat old programs even when performance has stagnated for three months. I once spent an entire morning at a pool counting the stroke rates of a group of young swimmers. The results showed wide variation between swims, which points to a lack of breathing rhythm stability and a weak feel for the water—something a simple stopwatch cannot reveal. A strong swimming nation should not have to rely on discovering another Anh Vien. It develops because a teenage swimmer becomes better at fifteen than he or she was at fourteen; because a provincial coach can call a nutritionist whenever needed; because every club has a five-year tracking file for every athlete. In countries with highly developed swimming systems, clubs and schools work like an assembly line. When I watch youth meets in Australia or Japan, I am not impressed by one young swimmer breaking a record; I am impressed by the number of athletes whose times fit within a narrow range. Their water is deep. We are still trying to dig one very deep well instead of widening the lake. After the 32nd SEA Games in Cambodia, experts asked why Vietnamese swimming had not achieved a new leap forward. I was not surprised. The gap between an outstanding individual and a strong team shows up most clearly when that person leaves. Nguyen Huy Hoang and Tran Hung Nguyen are promising talents, but they cannot carry the whole national expectation on their shoulders alone. The problem is not them; it is the absence of a deep succession pool that creates competition in every practice. In swimming, the gap between the number one and number two swimmers in a national team is a vital indicator. The smaller that gap, the greater the training pressure and the faster the results improve. I want to explore a counterintuitive angle: Anh Vien’s success over more than a decade may have made us comfortable with a “single-engine” model. When one athlete dominates entirely in domestic competitions, the others tend to focus on silver and bronze. Managers also tend to direct resources toward the one who has already proven herself. That is rational in the short term, but it slows down the creation of depth. A national championship where many swimmers finish close together is worth more than an event where one star pulls three seconds ahead. That value will not appear on the medal tally, but it will appear in training sessions five years later. Data about heart rate, swimming distance, repetitions, and transition speed between laps needs to be stored in a shared database. Without that database, we will keep repeating the same argument about why Vietnamese swimming has not advanced far at the Olympics. The strongest swimming nations treat data as part of practice, just like warming up. I am not talking about reducing athletes to dry numbers. I am talking about turning numbers into useful tools for coaches so they can make sharper decisions and save athletes’ time. One example I often mention is the 400-meter individual medley. In that event, pacing is decisive. When I watched several young Vietnamese swimmers, they often performed well in the first 150 meters but slowed dramatically in the 50-meter breaststroke leg. Some said their breaststroke technique was weak. But when I looked closely, the real issue was the transition rhythm after the backstroke leg. They failed to shift the body position from backstroke to breaststroke quickly, creating a near-static pause before the first pull. That pause lasts about 0.3 seconds, and repeated over four laps it adds up to a loss of more than one second. In swimming, one second is a whole world. The swimming ecosystem also needs to be viewed through infrastructure. Not every province has a competition-standard pool. Many young athletes train in 25-meter pools, so when they move to a 50-meter pool, the feeling of stroke count and water pressure changes completely. We need a pathway that lets talented juniors experience long-course pools earlier, not just before every SEA Games. Meanwhile, support staff for performance analysis barely exists at the provincial level. Coaches must handle the lesson plans, the psychology, and the role of a researcher all at once. In a single training session, no coach can do all of that and still notice half a breath cycle in each athlete. I remember standing at a provincial pool when a young coach told me, “I know this swimmer needs technical correction, but I do not know the scientific way to fix it.” That sentence haunted me. The problem is not passion; it is the lack of a knowledge-transfer system. That system should start with underwater filming for every swimmer, analyzing elbow angles, pull speed, and body displacement after each dive. When we have video and exact numbers, correcting technique no longer relies on guesswork. Vietnamese swimming does not need an immediate shock. It needs small innovations repeated over many years, just like a distance swimmer who keeps a steady stroke rate from start to finish. From mispronouncing an athlete’s name at the World Cup, I learned that every accurate statement begins with listening and verifying. In swimming, accuracy begins with a coach’s ear listening to an athlete’s breathing rhythm and with eyes looking at numbers that change every week. The journey from one special talent to a deep swimming foundation may take more than a decade. But if we do not start now, ten years from now we will still be writing the same kind of analysis under the same title. In the coming season, I want to try something: build an open dataset recording the results of all young Vietnamese swimmers from 14 to 18 years old at national meets and follow them for three consecutive years to see who improves most consistently. That is where swimming people can find answers earlier, before the big clock at the Olympics speaks. Tonight’s question is not whether we can find another Anh Vien. The question is whether we have enough patience to build a system that can create more Anh Viens, even when that journey does not have stadium lights shining on it every day.
