Seeking a Technical Foundation for Vietnamese Swimming After Madrid 2026

On August 23, 2026, the fifth World Swimming Championships closed in Madrid after eleven days of competition. Along the lanes of the 50-metre pool, the East German swimmers left a mark that forced coaches to rethink how swimming is taught. What stood out was not raw speed but the smoothness of movement: a compact pull, a well-timed breath, a turn that lost no momentum. No Vietnamese reporter was in the stands in Madrid that year. Yet the question the meet left behind stayed in the coaching rooms: why can the same distance be covered with fewer strokes and still be faster? That is a technical question. Data only recounts; tactics begin with mistakes. CONTEXT In 2026, Vietnamese swimming was still at an early stage of scientific coaching. Pools meeting the 50-metre standard could be counted on one hand, most of them in the big cities. Most athletes trained in short pools or in natural water, where measurement relied on a stopwatch and the coach's experience. Names such as Michael Groß of West Germany and Kristin Otto of East Germany were already echoing into distant pools. That same year, the tenth Asian Games were held in Seoul in late September, offering a chance for countries in the region to compare standards. Placed side by side, the gap appears in two layers. The first is physical capacity and training conditions, hard to close overnight. The second, and more troubling, is the technical foundation: hand entry, the angle of the pull, breathing rhythm, and the turn at the wall. The second layer can be narrowed by method, not necessarily by money. Walking into the world of Vietnamese swimming data, I learned to stay silent before the numbers. TECHNICAL ANALYSIS The start and the underwater phase decide a significant share of performance in short events. In Madrid, the leading swimmers held their bodies straight as a spear as they left the blocks, then used momentum to glide underwater before surfacing at the right moment. At home, most swimmers surface too early because they cannot control their underwater breathing. The free distance that momentum provides is wasted. Pull efficiency is where measurement is clearest. A freestyle swimmer typically needs about forty to fifty strokes for 50 metres. The fewer the strokes without a drop in speed, the higher the efficiency. Leading swimmers sustain a long stroke through two factors: a horizontal body line with little lateral movement, and a push phase that extends to the hip instead of stopping at the chest. This is a technical difference, not a difference in innate strength. The turn is the same story. In a short 25-metre pool, a 400-metre event may include up to fifteen turns. Half a second lost on each turn costs nearly eight seconds in total, a gap too large to recover with swimming speed alone. A good turn preserves momentum: legs tucked tight, the body rotating around its long axis, and the push off the wall driving straight into the glide position. CONTRARIAN ANGLE The understandable reflex when a swimmer is slow is to add training volume: more swimming, more running, more pulling. Put in the right place, that reflex is wrong. When the technical foundation is off, every extra metre only reinforces the error. A faulty pull is repeated thousands of times, and the more it is trained, the harder it is to fix. I do not believe in intuition. I believe in how many variables that intuition has been loaded with. The same goes for management. Investing in a proper pool is necessary, but without a proper coaching method the pool only multiplies a weak technique on a larger scale. What Vietnamese swimming lacked in 2026 was not water so much as a way of measuring water. Based on my experience watching domestic meets and recording every wall touch by the swimmers, I believe the error lies in observation. The human eye remembers the finish, not the third breath or the twentieth pull. To fix it, we must record what the eye does not keep. TAKEAWAY After Madrid 2026, what matters more is not how to swim as fast as the East Germans. It is this: in a pool, how far does each stroke of a Vietnamese swimmer push the water, and how many fractions of a second does each turn cost? Measure that number and we have a starting point. Without it, every conclusion remains a guess.
