Vietnamese Swimming: When Data Remains a Gap

At the 31st SEA Games held at home, when Nguyen Huy Hoang touched the wall in the 1500m freestyle with a time of 15 minutes 00 seconds 12, the whole stadium erupted. But few noticed that in the technical room, experts shook their heads due to the lack of data to analyze each arm rotation and each breath of this swimmer. That is a miniature picture of Vietnamese swimming: talent exists, but the data system is almost zero. Vietnamese swimming has made significant progress over the past decade. From Nguyen Thi Anh Vien's achievements at SEA Games to Nguyen Huy Hoang's rise in the Asian arena, we can see great potential. However, when looking at leading countries like the USA, Australia, or even China, we notice a huge gap in technology and data. These national teams use 3D motion tracking systems, biomechanical analysis, and performance prediction algorithms. Meanwhile, in Vietnam, data collection still relies on stopwatches and coaches' intuition. Data in swimming is not just about results. It includes technical analysis: entry angle, glide depth, stroke rate, and kick efficiency. Monitoring heart rate, lactate concentration, and other biological indicators. This data helps optimize training plans, refine techniques, and predict injury risks. In Vietnam, we lack most of these tools. Youth training centers still rely on traditional methods, with a coach observing and giving feedback with the naked eye. This leads to talented athletes not being fully exploited, and small technical errors not being detected in time. Take Huy Hoang, for example, who holds national records in many events. He can swim 1500m at an impressive pace, but if we had detailed data on each arm rotation, we could find the optimal point to save energy. Similarly, Anh Vien, with excellent technique, could improve further with underwater movement analysis. These require a synchronized data system, from collection, storage, to analysis. However, there is an opposing view: is the lack of data really the biggest barrier? Many countries have modern data systems but still cannot produce outstanding athletes. For instance, India invests heavily in technology but its swimming achievements remain modest. Conversely, Kenya, despite lacking everything, still produces world-leading long-distance runners. This shows that beyond data, there are factors like sports culture, spirit, and training environment. Perhaps relying on the intuition of experienced coaches, as we still do, could be an advantage in certain situations. But that doesn't mean we should reject technology. Vietnamese swimming is at a crossroads. We have talent, we have passion, but we lack a data system to elevate. Investing in data is not a luxury but an essential need to compete internationally. But above all, we must remember that data is just a tool, not a replacement for the spirit and will of humans. Let data serve people, not the other way around. Looking back at the history of Vietnamese swimming, we see remarkable progress since the 2000s. Swimmers like Nguyen Huu Viet and Nguyen Thi Anh Vien have put Vietnam on the regional swimming map. But to go further, we need a data revolution. Imagine a national training center with underwater sensors, high-speed cameras, and motion analysis software. That is not too far-fetched if we have the right investment strategy. The current situation shows that swimming clubs in Vietnam still operate in a fragmented manner, lacking connectivity. Each locality has its own training method, with no common standard for technique and data. This makes it difficult to select and develop talent. Meanwhile, countries like Japan and South Korea have built national data systems since the 1990s, creating a foundation for sustainable development. A bright spot is the emergence of smart wearable devices in training. Some young athletes have started using smartwatches to track heart rate and distance. However, this data has not been systematically analyzed. We need a team of sports data experts who can work with coaches to turn numbers into specific strategies. Huy Hoang's story is a typical example. He started swimming at age 10 in Quang Binh, where there was no standard pool. Thanks to his talent and effort, he rose to the top of the region. But with good data, perhaps he could have achieved even more. Similarly, Anh Vien, though retired, her lessons remain valuable. She once shared that the lack of analytical equipment forced her to figure things out on her own, relying on her own feelings. We also need to look at China's model, where they invested heavily in data since the 2000s. They built sports research centers and collaborated with universities to develop technology. As a result, they created a generation of world-class swimmers like Sun Yang and Ning Zetao. Vietnam can learn from this experience but needs to adapt it to its actual conditions. However, having data does not guarantee success. Human factors remain the most important. A good coach can spot technical errors that machines cannot detect. An athlete with a strong spirit can surpass their own limits. Data is just a supporting tool, it cannot replace creativity and passion. Therefore, we need to harmoniously combine tradition and modernity. Looking to the future, I believe Vietnamese swimming will make a breakthrough if we invest wisely. In the short term, we need to build a national swimming database, storing information of all athletes from grassroots levels. Then, we can use analytical tools to identify potential talents. This not only helps the national team but also improves training quality in localities. We also need to train human resources in sports science. Currently, the number of sports data experts in Vietnam is still very small. We can send students abroad or invite foreign experts to teach. This is a long-term investment but will yield enormous benefits. Finally, I want to emphasize that data is not the destination but the means. We should not be overly dependent on machines but use them as a tool to maximize human potential. Swimming is a sport of harshness, of limits, and of will. Let data help us overcome those limits, but don't forget that heart and desire are what make the difference. The flame of Vietnamese swimming has been lit by swimmers like Anh Vien and Huy Hoang. Now, we need to add the flame of technology and data to take Vietnamese swimming further. Let's start with small steps: collect data from domestic competitions, analyze it, and draw lessons. Only then can we compete fairly with world swimming powers.
