Vietnamese Athletics and the Missing Injury File: A Verdict Written in Advance, Read by No One

Vietnamese Athletics and the Missing Injury File: A Verdict Written in Advance, Read by No One

In the women's 3000m steeplechase final at the 32nd SEA Games in Phnom Penh in May 2026, I sat in front of the screen and clicked my stopwatch on every foot strike of a Vietnamese athlete. Past the two-hundred-metre mark, her left foot landed angled outward, the ankle rolling some seven degrees before correcting itself two strides later. I wrote that number into a yellowed notebook. No one else wrote it. When the meet ended, the entire file on her in my hands was one scrawled line from an analyst with no access to any medical data at all.

Three weeks later, on a sports forum, people argued over whether she should also run the 1500m. No one mentioned the ankle. No one had data to mention. The debate ran on feeling, and feeling, as always, beats data — simply because the data never existed to lose.

Athletics is a sport of numbers. A 400m track is measured to the millimetre, a high-jump bar is adjusted to the centimetre, wind is measured in metres per second, and a reading above +2.0 m/s instantly strips a mark of record status. And yet, when it comes to the injuries of the athletes themselves, an entire athletics culture accepts living in a blind spot.

In developed athletics nations, every elite athlete is a living file: the personal-best curve season by season, the number of appearances, injury history, rehabilitation protocols, mental-health status. Federations archive it, sports-science centres analyse it, and people in my trade can read ten years of data on a single name to find the pattern.

In Vietnam, I once asked for the season-by-season personal-best data of an athlete who had won a SEA Games medal. What I received was a few photographs of handwritten paper score sheets, some of them blurred. No curve, no milestone, nothing to set beside each other between this season and the last. An athlete can leap to a mark three times faster than their historical annual gain within a single year, and we will cheer it as a "breakthrough" — while elsewhere, that is a signal to open an investigation file. Based on my experience following matches, I have never seen a sports system compete so much while recording so little.

Vietnamese athletics does not lack fast runners; it lacks people who write down why they run fast, and why one day they will stop. That is the whole problem, packed into one sentence.

A decent injury file begins with the run itself. Not the final number on the scoreboard, but how that number came to be: where the athlete accelerated, how long the stride was, what the cadence was, and most importantly, the conditions of measurement. The same 11.20-second 100m for a woman is worth something entirely different with a +1.9 m/s tailwind than with a -0.5 m/s headwind. At our national meets, wind readings are rarely published alongside results, and even more rarely archived. We keep the results but drop the conditions.

Then there are the shoes. In recent years, carbon-plated shoes have saved athletes a few seconds per lap. A record set in those shoes is not entirely the achievement of the foot. To judge it properly, one must deduct the "equipment dividend". We have not built that habit. The mark is simply entered into history as a pure advance of the human body.

The body's curve is the most important part of all. Every event has a different peak window: sprinters usually mature between 24 and 29, middle- and long-distance runners between 26 and 31, while throwers can last to 33. From age alone, one can guess whether an athlete is climbing or past the summit. But building that chart requires years of data, not a single timing at a single Games. Vietnamese athletics owns brilliant medals at 19 and 20, then quietly lets athletes fade at 25 — with no one able to draw the curve showing where that fade began.

This is where I place my faith in something with a name: the hip-rotation coefficient. For a runner, the hip is the transmission axis. When the hip rotates off-line, force does not travel straight ahead but spills to both sides, and the knee and ankle must carry the surplus. The hip-rotation coefficient never lies; only people deliberately misread it. But to read it, you must film, measure, and archive month after month. We do not do this for the majority of athletes, so every injury arrives like a storm out of a clear sky.

The selection picture deserves a mention too. Places at major meets are allocated along two paths: hitting the qualifying standard, or accumulating ranking points. Where a country has depth, internal competition is harsher still, since an event may send at most three athletes — the fourth-place finisher at the trials is done for the season, even at world-medal standard. Vietnam has not yet faced that crunch in most events, but precisely for that reason we have never felt the pressure to build a serious selection-data system. Less competition, less transparency, less data.

Anti-doping is the clearest example of the loop. Samples are stored for ten years so they can be retested; athletes' biological profiles are tracked over time; missed tests after call-ups are all recorded. All of it requires a database running longitudinally across years. Without that data, recording no violations does not mean clean. It only means we have never been capable enough to look.

Then there is the training system. An athlete raised in a national centre, in a private training group, or from the school system carries different strengths and weaknesses. Where there is a doctor, a rehabilitation specialist, a movement-measurement lab, injuries are caught early. Where one coach doubles as doctor and healer, everything depends on one person's intuition.

There is a counterintuitive point I want to state plainly: the silence of injury cases is not evidence of health. An empty file does not equal a clean file; it is a file no one has opened. When the news ticker has no "athlete injured" entry, many read it as "the team is intact". The technical reality is different: with no recording system, all we see is a zero — and that zero is meaningless, just like failing to find a key in a room whose light was never switched on.

Another counterintuitive point lies in the selection model. We love teenage athletes who shine, because medals come early. But the fastest runner at 17 is usually the one trained earliest, loaded heaviest, and most likely to become the most fragile at 24. A system that rewards instant peaks will inadvertently produce bodies squeezed too soon. This is the blind spot of the entire short-term mindset in elite sport, and it is quieter than any refereeing controversy.

One more blind spot touches us, the people who sit and analyse. I do not prophesy; I only read the code the body wrote in advance. That code is not in a single match but in thousands of training days no machine ever monitored. Without data, the best analyst is only a charming storyteller. And a sports system run on charming stories convinces audiences easily, but protects its own legs very poorly.

Injury is the one thing on the track that never negotiates. It does not care about medals, marks, or lights. The only way to bargain with it is to understand it before it speaks, and to understand it, you need data.

Years ago, I built an injury dataset for more than five hundred domestic footballers, numbering each case like a code. Athletics deserves a similar set: open, public, so anyone can look up the curve of a pair of legs. A track record is measured in hundredths of a second; the career of the person who set it should be measured in years.

The next meet will come again, and the stands will roar again. Will we once more sit waiting for some ankle to roll seven degrees, with nothing in hand to say it had rolled that way for years?
