Underwater Raceways: Mapping Vietnamese Swimming Inside a Major-Tournament Cycle

The Sound of Water Breaking at the Wall The sound of water breaking at the wall is the first thing I learned in this profession, before any starting signal or final whistle. A hand touches the wall, the water closes behind the swimmer, and inside that pause an entire career can be decided. I have stood in the mixed zone of aquatics arenas many times, ears still ringing from the crowd, eyes fixed on the blinking timing board. Each time, I remember one thing: every number in the world begins with a very small sound. In 2026, when I was first sent to cover a regional multi-sport games as a student reporter, I assumed swimming was a sport of numbers. How many metres long, how many lanes, how many seconds on the clock. Then I learned the opposite. Swimming is a sport of silences. Between two breaths, between two hand entries, there is a world the clock can never measure. Some races are not measured by the clock, but by the silence between two heartbeats. That is why, entering the current major-tournament cycle, I do not want to write an ode to results. I want to reconstruct a map. That map is not only fifty metres of water and medals hung around necks. It also includes the entire system behind them: from the training pools in provinces, to the desks of the rule-makers, to the seats of spectators, and even the sponsorship contracts now reshaping how Vietnamese swimming operates. A Major Cycle Compresses Emotion A major-tournament cycle is a concept every sports reporter must internalise. It is not a simple schedule. It is a compressor. In a short window, an athlete's whole career, a federation's whole plan, and a nation's whole expectation get squeezed into a few days of competition. The pressure does not come from rivals. It comes from the compression itself. For Vietnamese swimming, this cycle has a particular character. This is a transition period. One golden generation has passed its peak, a new generation is searching for its footing, and in between lies the gap every sports system fears most: the gap of successors not yet ready. I have followed regional matches and continental games for years, and I have learned this: a swimming nation does not collapse because it loses a star. It collapses because no one stands behind the star. Context matters here. Vietnamese swimming has genuinely progressed over the past decade. From entering regional events as a guest, we now have athletes capable of contending for medals at continental level and meeting Olympic standards. That is an undeniable achievement. But precisely because we have reached that threshold, the question is no longer whether we can, but whether it lasts. During a major cycle, readers get swept up in flags and medals. That is natural. But the job of a sports writer is not to add more fuel to that emotion. It is to keep the analysis anchored to what actually happens beneath the surface. Underwater, there are no flags and no medals. Only technique, heart rate, and preparation. There is a detail I always recall. It is the moment before a swimmer steps onto the starting block. The noise of the stands remains, but for the athlete the world has narrowed into a fifty-metre straight line. I have learned that in silence, an athlete's heart beats louder than any roar. That is why I begin this analysis with technique, not with a medal table. Technique is where truth cannot be disguised. Dissecting Technique: From Start to Touch Modern swimming is decided by four phases: the start and underwater phase, the mid-race swim, the turn, and the finish. Of these, the first and third are the most often overlooked by spectators, yet they are where the most time is created. Begin with the start and underwater phase. In short events such as the 50m and 100m, the underwater phase after the start can account for up to thirty percent of total race time. This means an athlete whose reaction is only three hundredths slower can make up and overtake within the first fifteen metres if their underwater technique is superior. I have watched Vietnamese swimmers in this phase many times and seen a repeating pattern: good reaction, suboptimal underwater technique. Specifically, an effective underwater phase requires a straight body line, a tight core, and small, high-frequency kicks just beneath the surface. Many young swimmers kick too wide, generating drag that exceeds propulsion, so they surface earlier than optimal. This is a technical flaw that is hard to fix because it embeds itself in reflex, yet it can improve markedly with a few months of methodical coaching. Move to the mid-race. Here the concept of stroke efficiency matters. Stroke efficiency is the distance covered per stroke cycle divided by stroke rate. A swimmer can go faster by increasing rate, or by increasing distance per stroke. These two paths produce two completely different athlete types, and misjudging your own type is the most common reason athletes plateau. In Vietnam, I notice many swimmers are trained toward higher rate. This yields quick results early, especially in short events, but sets a very early ceiling. Once stroke rate has reached its physiological maximum, there is no headroom left. By contrast, the European and Oceanian swimmers I observed at international meets are often built around distance per stroke, with moderate rate and high efficiency. They take fewer strokes but travel further per stroke. This leads to what I consider the core insight: the gap between Vietnamese swimming and elite world swimming is not physical, but philosophical. We teach swimmers to swim fast, while the world teaches swimmers to swim efficiently and then fast. The order matters, and it explains why many of our young talents explode at fifteen or sixteen and stall at eighteen or twenty. The turn, the third phase, is the second most overlooked. In a 200m long-course race, a swimmer makes only three turns, but in the 1500m the number approaches thirty. Each inefficient turn can cost three to five tenths of a second. Multiplied by thirty, the gap can reach fifteen seconds, enough to change the entire ranking. I have reviewed dozens of footage clips of Vietnamese swimmers in distance events, and the striking thing is that they often lose momentum right after touching the wall. Instead of using the wall's push to launch, they linger too long in a tucked position before executing the tumble. This wastes energy, and in distance events it accumulates into a significant time debt. The finish is where fighting instinct shows most clearly. Swimmers who finish poorly tend to shorten their stroke over the final two cycles, or lift their head too early to look at rivals. Correct finish technique requires keeping the head down, increasing stroke frequency, and lifting the head only after the hand has touched the wall. It is a small but decisive detail, and I have seen talented swimmers lose medals simply by lifting their head half a stroke too early. Performance Coordinates and the Historical Gap To understand a swimming result, you must place it in three coordinates: the world record, the all-time list, and the current-season world ranking. A result only has meaning relative to these. For Vietnamese athletes, the gap to the world record is measured in seconds, sometimes dozens of seconds in distance events. In the men's 1500m freestyle, the gap between a leading Vietnamese swimmer and the world record is substantial. But the point is not the absolute gap. It is the rate at which that gap narrows over time. A rising swimming nation is one whose gap shrinks every cycle. A stagnating one is one whose gap stays fixed. Based on my experience following matches, I find the gap between Vietnamese swimming and the continental elite is trending down in some events while holding steady in others. This differentiation matters, because it shows no single policy can serve all events. Sprint and distance swimming need different training systems, different nutrition philosophies, and different tactical approaches. Another dimension of performance data is split structure. In swimming, a race is divided into fifty-metre splits with recorded times. A negative-split swimmer, faster in the back half, usually has better endurance and tactics. A positive-split swimmer, faster in the front half, usually blasts off and accepts fading later. In short events like the 100m, a positive split can be correct in some cases, especially when a swimmer knows they are strong in the start. But in distance events like the 800m or 1500m, a positive split signals a pacing error, and it often leads to total collapse at the end. I have repeatedly watched young Vietnamese swimmers go out too fast in the first two hundred metres of a 1500m, then crash over the final four hundred. This is a tactical error, not a physical one. Interestingly, the same problem exists at world level. Many elite swimmers make pacing mistakes, but the difference is that they have coaches sharp enough to intervene during training. They have performance labs, heart-rate and blood-lactate measurement at the poolside, and databases comparing every split. Vietnamese swimming lacks precisely this data infrastructure. One thing must be said clearly about the value of a result. A national record can carry great spiritual weight, but technically its value depends on whether it was set in a 25m or 50m pool, under what competition pressure, and in what technical era. Ignoring this context is the fastest way to misread a result. The Competition System: From National Trials to Continental Arena Vietnamese swimming operates inside a clear competitive pyramid. At the apex are the Olympic Games and the World Championships, where qualification standards are the A-cut and the B-cut. In the middle are the Asian Championships and continental games, where leading athletes can contend for medals. At the base are regional multi-sport games, where Vietnamese swimming regularly wins. On A-cut and B-cut standards, one point matters: the A-cut grants direct entry without depending on national quotas. The B-cut only counts when the national federation still has a quota and decides to send the athlete. This distinction directly shapes strategy. An athlete wanting certainty of an Olympic berth cannot simply target the B-cut, even if it looks easier. In practice, the B-cut is often a psychological trap. I once saw an athlete hit the B-cut and believe they would be selected, only to be left off the final roster because the quota had gone elsewhere. That is a brutal psychological shock any sports system should avoid by communicating selection rules clearly. Athletes deserve to know exactly where they stand in the pyramid. Japan, my homeland, has a selection system that is harsh but transparent. Athletes know that to reach the Olympics they must clear a fixed national trials meet, and achieve the A-cut there or beforehand. No exceptions, no discretionary picks, no negotiation. Over the long run, this harshness is a benefit, because it removes subjective judgement entirely and forces athletes to peak at the right moment. Vietnamese swimming does not yet have such a fixed and transparent selection mechanism. The current mechanism still depends on many factors, including some unrelated to performance. This is a structural barrier that must be faced directly. On schedule density, the current major cycle poses a particular challenge. Athletes face several consecutive meets within a short span, from regional to continental events to Olympic qualifying. Each meet demands its own peak, and sustaining multiple peaks within one year is an extremely hard physiological problem. Many athletes surge at one meet and fade at the next, not because they are weak, but because the schedule is simply too dense. Competition officiating must also be considered. In swimming, faults such as a false start or an illegal turn can lead to disqualification. These risks are rare but devastating, because they erase months of training in a single moment. Athletes must be coached not only in stroke technique but in competitive discipline. The Global Power Map of Swimming To understand Vietnam's position, look at the global power map. World swimming is led by a small group of nations, with the United States and Australia the long-standing dominant forces. China has risen strongly in many events, especially butterfly and women's freestyle. Britain, France, Italy, Hungary, and Japan are first-tier powers with their own stars. The dominance of the US and Australia rests on three pillars: a brutally competitive selection system, modern training infrastructure, and a swimming culture embedded in daily life. There, a child can start swimming early inside a dense club system and be discovered through professionally run age-group meets. China's model differs, centred on national training centres and centralised selection. This model produces stars with impressive times but sometimes struggles to sustain long-term athlete motivation. Japan, my homeland, combines corporate club teams and national centres, a model I consider best suited to Vietnam's conditions. The Japanese corporate club model works like this: major companies sponsor swim teams as part of social responsibility and brand strategy, athletes are salaried like employees, train full-time, and compete under the company colours. This model solves the financial problem of professional athletes while retaining competition between teams. In Southeast Asia, nations such as Singapore and Malaysia have also built notable swimming systems, with athletes capable of competing at continental level. Vietnam has a far larger population but has not fully tapped this resource. This is a missed opportunity. One rarely mentioned aspect of the power map is personnel movement. Many elite coaches move between nations, carrying knowledge and methods. Attracting good foreign coaches, and more importantly keeping them long enough to build a system, is decisive. Hiring a good coach for one season does not create lasting change. Building a new coaching school takes years. Rules, Doping, and the Grey Zone of Responsibility Swimming is governed by a strict rule system and is among the sports under the most rigorous doping surveillance. Any athlete competing internationally must comply with out-of-competition testing, whereabouts reporting, and valid therapeutic-use exemptions. In Vietnam, anti-doping education has received more attention than before, but gaps remain at the grassroots level. Many young athletes do not fully understand that an ordinary cold medicine bought at a pharmacy can contain a banned substance. This is a serious risk, because under anti-doping law an athlete bears strict liability for what enters their body, whether or not they knew. One point must be stressed to avoid misunderstanding: the absence of detected doping cases does not equal the absence of risk. It simply means the topic has not been explored deeply. A good anti-doping system is not one with no cases but one with transparent testing, education, and adjudication. Beyond doping, equipment rules are another zone of attention. Modern racing suits use high-tech materials, and rules on buoyancy, elasticity, and material thickness constantly change. A suit legal this season may be illegal the next. Athletes and coaches must track these updates closely to avoid disqualification on technical grounds. It is essential to separate event from opinion when reporting on rules issues. If an athlete is under investigation, that is an event. Whether the athlete is guilty is a conclusion for the competent authority, not the reporter. In the past, there have been cases where media concluded too early and caused irreparable harm to an athlete's reputation. Athlete Careers and Team Systems To analyse a swimmer's career, place them on an age-performance curve. Swimming differs from many sports: peak performance often arrives early, especially for women. Many female swimmers hit their best times at eighteen or twenty. This makes puberty a serious physiological barrier. As the body changes, body-fat ratio rises, muscle mass ratio falls, and stroke efficiency drops. Many young talents who surge before puberty stall afterward, a phenomenon common in women's swimming worldwide, not unique to Vietnam. For male swimmers, the peak usually arrives later, around twenty to twenty-five, and can last until nearly thirty. This creates a longer competitive window but also demands a more sustainable financial and medical support system. The team system is decisive. A swimmer is alone on the lane, but behind them is always a team. The head coach builds the philosophy. The conditioning coach builds the foundation. The nutritionist manages biological fuel. The psychologist holds the mind steady. The physiotherapist prevents and recovers injuries. Remove any link and the chain weakens. In swimming, the two most common injuries are the shoulder of freestyle and butterfly swimmers, and the knee of breaststroke swimmers. Both are overuse injuries from movements repeated thousands of times a day. Injury prevention in swimming is not rest but building strength in opposing muscle groups and adjusting technique to reduce joint load. On competitive psychology, this is an area Vietnam should invest in more. The pressure in a major final is brutal. A whole year of training is compressed into two minutes. Any small psychological fluctuation can convert into a large performance one. Believing this and preparing the mind seriously is the only way an athlete avoids sabotaging themselves. Multi-event load must also be weighed. A swimmer contesting several events, from 200m to 1500m, faces a dense schedule of heats, semifinals, and finals. Managing this load is an art, and sometimes the wisest choice is to drop one event to focus on another. Risk Profile A serious analysis must face risk squarely. For Vietnamese swimming in the current cycle, I identify the following main risk groups. Competitive risk is dependence on a few individuals. When a nation's results rest on one or two athletes, a single injury or dip in form removes the entire system's anchor. This risk is especially severe because it cannot be solved in the short term. Systemic risk is the generational gap. Without successors trained and ready, the next golden generation will not appear at the right time. This must be addressed at the grassroots level, where talent is discovered. Financial risk is dependence on state budgets and short-term sponsorship. Professional athletes need stable income to focus on training. When funding is unstable, athletes are forced to worry about livelihood instead of the lane. Medical risk is the shortage of recovery and injury-prevention specialists. An athlete with a shoulder injury that is not treated correctly can lose an entire season, or worse, a career. Psychological risk is the pressure of expectation from media and the public. When over-praised, athletes are vulnerable on failure. When over-criticised, they lose confidence. Balancing expectation is the responsibility of all, including the media. Of all these, I judge systemic risk the most serious, because it affects the entire following cycle, not just the current season. Solving it demands a long-term, patient, persistent strategy, something football often has in abundance and individual sports like swimming often lack. Public Narrative and the Expectation Gap Swimming has a great advantage in building public narrative: it produces dramatic moments within seconds, and those moments spread easily on social media. A record-breaking touch can generate millions of views in hours. But this advantage is also a trap. When public narrative focuses on the moment rather than the process, it creates distorted expectations. The public begins to believe miraculous moments can repeat easily, and when they do not, it feels disappointment. The expectation gap in Vietnamese swimming has three tiers. The first is expectation of medals at regional events, where we genuinely compete. The second is expectation of advancing deep at continental events, where we can compete but not consistently. The third is expectation of Olympic medals, where our gap remains very large. The problem is the public often merges the three. Success at the first tier is interpreted as potential at the third, creating unrealistic expectations. This is where sports reporters have a duty. Our job is not to extinguish ambition but to place ambition in realistic context, so the public understands each step forward needs time and system. Another notable aspect is how public narrative treats failure. In many developed sports cultures, failure is a natural part of the process, and athletes receive sympathy rather than criticism. In Vietnam, we are gradually learning this, but there are still cases of athletes harshly criticised for missing expectations despite giving their all. This is a sports-culture issue to improve from both sides. An example of the power of the right narrative is how we treat athletes from difficult backgrounds. When the story is told with respect, not melodramatised, it creates genuine empathy. When it is exploited as a media stunt, it creates distaste. Reporters choose how to tell it, and that choice has real consequences for athletes' lives. The Ripple Effect of the Swimming Industry Swimming is not only a competitive sport. It is an industry with a value chain stretching from children learning to swim in community centres, to professional pools, to equipment brands, to broadcasters and streaming platforms. At the upstream end is the learn-to-swim market and talent discovery. This is where every strong swimming nation begins. Without a quality learn-to-swim system at the grassroots, there is no way to discover and nurture talent early. Investing upstream brings no immediate medals, so it is often skipped in short-term plans. In the middle are the athletes and events. This is where value is created directly, through results, image, and story. Downstream are derivative markets: advertising, sponsorship, equipment, books, instructional video, and sports tourism. A successful swimming star can generate economic value far beyond their worth on the lane, through endorsement deals and public appeal. The problem in Vietnam is that this value chain is not tightly connected. Learn-to-swim centres operate independently, athletes compete mainly for multi-sport games, and equipment brands have not fully tapped the market. This is an untapped opportunity, and it can generate sustainable financial resources for Vietnamese swimming if organised correctly. In this context, I want to state a view on the sports business. The sports-rights bubble has peaked. Streaming platforms are losing money buying rights, repeating the mistakes of the old broadcasters. For Vietnamese swimming, chasing a model of selling exclusive rights to a single platform may bring short-term cash but harms public access in the long run. Vietnamese swimming is at a stage where it must broaden audiences, not shrink them. Because a sport few watch is a sport no one will pay to watch. A more attractive direction is content development. Behind-the-scenes stories, technical-breakdown videos, and interactive programmes with the public are content assets that create value without selling exclusive rights. This is a direction many sports are pursuing, and it suits swimming's character: a sport rich in deep human stories but seldom told well. The Unmeasured Breath When I began this article, I asked what would make a map of Vietnamese swimming useful rather than just a heap of data. After moving through every dimension, from technique to system, from rules to business, I realised the answer is simple: Vietnamese swimming is at the exact moment when one strategic decision can shape the whole next decade. What makes me optimistic is that the foundation exists. We have athletes who have proven themselves internationally. We have a generation of young coaches with access to modern knowledge. We have a large pool of young people who love swimming and parents willing to invest in their children. What is missing is the connection between these three resources into one system. What worries me is impatience. Vietnamese sport has a habit of chasing short-term results, and swimming is no exception. But building a strong swimming nation takes time, and requires steadfast investment in the grassroots even when no medals appear. This is a psychological problem harder than any physical one. Once, I stood poolside at five in the morning, watching a young athlete climb out of the water, take off their goggles, and stand breathing in the misty steam. No crowd, no media, no medal. Only a human being and a long lane. That is the truest picture of Vietnamese swimming. Everything else, medals included, is built from that silent moment. The empty stands of 2026 taught me that sport never falls silent, it only changes its voice. In this major-tournament cycle, I believe Vietnamese swimming is changing its voice too. The question is whether we are calm enough to listen, and brave enough to write the next notes that the stopwatch can never measure. One thing I always believe: the unmeasured breaths are precisely where a real sports culture is born, and a sports writer, like an athlete, can only stay true to their own journey by choosing to go slow and deep rather than fast and hollow.
