The Hidden Endurance Behind Every Rally: Vietnamese Women's Volleyball Through Breath and Data

The nineteenth minute of the fourth set, the SEA Games 32 women's volleyball final in Phnom Penh, May 2026. The ball crossed the net eleven times in twenty-eight seconds. The stands were silent. I sat in the press area, my hand resting on my notebook, writing nothing. A rally that long is rarely remembered, because it does not end with a spike that makes people leap to their feet. It ends with a ball touching a block and falling onto the opponent's floor — a point the scoreboard records in the smallest possible characters, but behind it are three jumps by a middle blocker no one names.

I kept that rally in my head longer than any of the match's thunderous points. In sport, what gets forgotten is rarely the moment of brilliance. It is the repetitive labor that makes the moment of brilliance possible. And in Vietnamese women's volleyball, that labor is now under a pressure the scoreboard never reflects.

That final ended with a 3-2 victory for Vietnam's women's team over Thailand, ending a drought that had lasted nearly two decades at the regional stage. I have watched enough women's volleyball to understand that a gold medal is not born from a single spike. It is born from breathing kept steady across twenty-eight seconds, on the eleventh touch of the ball, when the legs are tired and the eyes are blurred.

What I want to discuss here is not the medal. It is the invisible endurance that quietly lifted that medal, and the way Vietnamese volleyball is misreading itself by looking only at its most glittering numbers.

Before the analysis, some context. Over the past five years or so, Vietnamese women's volleyball has stepped out of the comfort zone of Southeast Asia to reach continental and global stages. The national team has competed at AVC Cups and Asian qualifiers, and at times appeared on the world stage reserved for lower-ranked teams. In parallel, the national championship — commonly shortened to the volleyball V-League — has become the place that nurtures, and also wears down, the fitness of nearly every national-team player.

At club level, the flow of foreign imports has grown stronger each season. Big clubs spend money to buy foreign outside hitters, sometimes for just a few knockout matches. It is a young market, where value is set by height and points scored, and not yet by the endurance value a player brings to the whole system.

And between those two layers — national team and club — sits a dense calendar. A core national player can play through the domestic league, then immediately join the national team, then return to the club, while the body never gets enough rest to regenerate. This is the biggest blind spot in Vietnamese volleyball today, and it rarely makes headlines because no statistical table measures fatigue.

When I rewatched match footage, I began counting by hand. Not points, but the number of jumps and the seconds the ball stayed in play. Fatigue in volleyball is not found in the points scored, but in the number of times a body must leave the floor within a single set.

Let us try a simple calculation. A middle blocker who participates in blocking and approach jumps can jump between forty and sixty times in a match lasting four or five sets. An outside hitter, who must both receive and attack at the net, can exceed that. Multiplied across a domestic-league calendar spanning several weeks, that figure far exceeds what most fans imagine when they watch a rally lasting a few seconds.

This is where I recall a lesson from the track. In athletics, I once rewatched hundreds of hundred-metre races and realized that performance does not come from the final sprint, but from how an athlete manages the first ten seconds. Volleyball is the same, except that here each set contains dozens of starts, and there is no finish line to stop at.

During a period when competitions were postponed, sitting alone rewatching footage, I told myself: In a twelve-square-metre room, 120 races taught me to listen to my own breathing. I wrote that line for myself, but it applies entirely to a middle blocker waiting at the net — someone who must listen to her own breathing to know when she still has the strength to jump one more time.

Now let us move into the core: the true operating system of a volleyball team, and why it is being misread.

First, the reception. In modern volleyball, without a stable reception system, the most beautiful attacking plays are meaningless. People often praise an outside hitter who scores twenty points, but those twenty points depend on whether the ball is delivered to the setter's hands at the right height. Reception is a form of labor that never appears on the scoreboard, yet it determines the quality of every ball that follows.

Watching Vietnam's women's team in major matches, I noticed a recurring pattern. In the early sets, the team's perfect-reception rate stays high, and attacks unfold in varied ways: middle blockers run quick, outside hitters attack the wings, opposites exploit the angles. By the fourth and fifth sets, that rate drops markedly, and the first thing to disappear is the middle blocker's quick attack. Not because the middle blocker has lost the ability, but because the ball is no longer delivered well enough for the setter to dare open the middle.

This is an endurance signal disguised as a technical signal. Viewers see the play become more one-dimensional and blame the setter. But the real culprit lies in legs that have slowed by half a beat, in reflexes that have lost their sharpness, in eyes that can no longer read the spin of a serve.

I built my own comparison table for several recent matches of Vietnam's women's team. In it, I recorded three columns: perfect receptions, attacks from the middle of the net, and points scored from live-ball situations. The correlation between these three columns is nearly linear in the first two sets, then breaks down in the decisive phase.

When reception quality falls, attacks from the middle collapse first — and that is the earliest sign that a team is running out of endurance. This explains why many strong volleyball teams lose the fifth set despite winning the first. They are not defeated technically. They are defeated energetically.

Here I want to tell a small story I once followed. In a domestic-league match, a young middle blocker played very well in the first three sets, blocking firmly and running quick. In the fourth set, she almost vanished from the attacks. In the stands, people said she had lost form. But looked at closely, the number of her jumps did not drop at all — she still jumped for every block. What dropped was the quality of the final jump, when her legs no longer had the strength to hold her height.

This is the kind of detail statistics overlook. A jump that drops five centimetres can turn a block into a touch that falls into your own court. In the eyes of the crowd, it is a failure of the whole system. In reality, it is the consequence of a body that has exceeded its endurance limit.

Now let us talk about the setter — the one who keeps the rhythm. In volleyball, the setter is the most undervalued position relative to its true importance. A good setter does not merely deliver the ball to the right place. She reads the breathing of the whole team: who still has strength, who is tired, who needs to rest one attacking beat to recover. The setter is the true endurance athlete of a volleyball team, the one who regulates the pace of the collective just as a long-distance runner regulates the lap.

Following one of Vietnam's women's team core setters across many matches, I saw her distribute the ball according to a logic that almost never changed. In the first two sets, she shared the ball evenly among the attackers. Mid-match, she began concentrating it toward the strongest outside hitter. Late in the match, she depended almost entirely on one person. That shift is not tactical laziness. It is a survival response when the other attackers have run out of strength.

Seen through data, this is a measurable problem. The number of sets delivered to each position, set by set, draws a very clear curve: varied at the start, concentrated at the end. And that curve, in most cases, does not reflect the opponent growing stronger. It reflects the team's own internal energy fading.

I once wrote about a team on the international stage that played three consecutive extra-time matches and still reached the final thanks to its ability to manage energy. I called it the art of endurance. In that article I wrote: Croatia did not run faster; they forgot that they were allowed to stop. I think that line fits Vietnamese volleyball in a different way. Our teams do not run slower than their opponents. We forget that we are allowed to stop — allowed to rest a core player for one match, allowed to let a set pass without needing to win it.

Here, I must say plainly something few in the profession want to hear. Loading the entire burden onto a few core players is not a tactic. It is a lack of squad depth concealed by short-term results. When a team has only one person capable of scoring in decisive rallies, that team is betting its future on the legs of an individual.

And this is where the story connects to the transfer market, a field I have followed for many years.

The flow of foreign imports in the volleyball V-League brings a paradox. In the short term, they raise the league's quality and help teams compete immediately. But in the long term, they can slow the growth of domestic young players themselves. When a club can buy an outside hitter who scores twenty points a match, the pressure to develop and give chances to a nineteen-year-old attacker disappears.

Every transfer deal is a farewell named hope. I wrote that line for football, but it holds for volleyball at a deeper level. Every time a club buys an import, a young player back home quietly loses a starting spot — and loses the most precious stretch of time to learn how to endure a long match.

An import's value is usually set by height and points. But seen through endurance data, the story differs. An import who plays only a few knockout matches can score highly but cannot raise the team's reception quality across a whole season. Meanwhile, a young domestic player, after a season of regular starts, can become a far more durable link.

I believe the young-player price bubble in Vietnamese volleyball has not burst, but it is inflating according to a flawed logic. Clubs do not pay for endurance value and the capacity to endure. They pay for points visible immediately in a televised match. That is a valuation based on the spotlight, not on the foundation.

At this point, I want to discuss a new force entering the locker room: data analysts.

In recent years, some Vietnamese volleyball teams have begun hiring people to record and analyse statistics. This is a necessary step forward. But it carries a risk. Conclusions drawn from data are often produced in a quiet room, detached from the real rhythm of a match unfolding before the eyes. A table of statistics can tell you who scored the most points, but it cannot tell you who still has the strength to jump in the decisive minute.

I once witnessed a situation where a substitution was made based on an attack index, but overlooked the fact that the incoming player had not been on court for two sets and could not find her rhythm. The number said she was more effective. Reality said she needed time to warm up. That detachment is precisely the blind spot of data analysis when it is not anchored to the breathing of the match.

Here I think of a deeper paradox of modern volleyball: the more data there is, the more people tend to reduce human beings to indices. A middle blocker can be undervalued for scoring few points, even though she blocks the most and creates the most live-ball situations for her teammates. A libero can be almost invisible in every statistical table, even though she is the one holding the whole system from collapsing.

This is where I want to offer a view counter to the majority.

The prevailing assumption in Vietnamese volleyball is that we need tall, high-scoring outside hitters, and that all resources should be poured into finding such people. That assumption is half right. Its wrong half lies here: in a match lasting five sets, the person who decides the result is usually not the one who scores the most, but the one who maintains the quality of her touch the longest.

I once followed a match in which the winning team did not have the highest-scoring outside hitter. That team won because in the fifth set, the entire lineup still maintained an almost intact reception rhythm. Meanwhile the opponent, with an exhausted outside hitter, hit the ball out on three decisive rallies. On the scoreboard, the losing team's outside hitter was still the match's top scorer. But on the floor, the losing team had lost something more important than points: the capacity to endure.

This leads to a counterintuitive conclusion. In volleyball, the endurance stability of the whole collective matters more than the individual peak of one star. And if that is true, then the way Vietnamese clubs currently allocate resources runs against their own long-term interest.

Here I recall the silence of a stand. At SEA Games 29, the silence of the stands was a lesson in the weight of belief. An athlete fell at the three-hundred-and-ninety-second metre, and the entire stadium could not utter a word. In volleyball, we have similar silent moments, except they occur in rallies that are never replayed. A middle blocker jumps too low. A libero touches the ball and it falls into her own court. Those moments have no cheering, but they carry the weight of an entire exhausting season.

From that perspective, I believe Vietnamese volleyball stands before a strategic choice. One path continues the old road: buy imports, concentrate the ball on the star, chase results match by match. The other builds a sustainable system: develop squad depth, manage endurance as a strategic asset, and treat reception as a foundation rather than a footnote.

The second path does not bring medals immediately. It demands a patience that Vietnamese volleyball, with its results pressure at every Games, often lacks. But it is the only road by which a team can compete at continental level without collapsing in the fifth set.

I want to return to that twenty-eight-second rally in Phnom Penh. What made me remember it was not the result, but the way the whole team kept its structure throughout. No one stood still waiting for the ball. No one abandoned a position. Each moved as if knowing where the other would be. That is an endurance built over thousands of hours of training, and it cannot be bought with a contract.

Over many years in this profession, I have learned that what is most worth writing usually lies in the forgotten part of the story. Not the decisive spike, but the breathing before that spike occurs. Not the star on the scoreboard, but the one standing in the corner of the court, receiving the eleventh ball of a rally whose name no one remembers.

Vietnamese women's volleyball is at a moment that could shape an entire decade. The gold medal at SEA Games 32 opened a door. The question is not how many more titles we can win. The question is whether we have the courage to build an endurance foundation and squad depth durable enough that the next medals do not depend on whether a few pairs of legs still have the strength to jump.

When the stadium lights go out, what remains is not the score. It is the breathing. And a mature volleyball nation is one that listens to that breathing before it breaks.
