Vietnam Volleyball's Medical-Room Log: When the Ankle Pays the Bill for the Calendar

Minute 19 of the fourth set: the outside hitter takes a three-step approach, jumps at the 3-metre line, spikes into a double block, and lands on the tip of her left foot. Up in the stands, I am holding the medical staff's tracking sheet. On that sheet she has jumped 71 times in this match, plus 128 times in the morning session the same day. Nobody inside the arena needs to know that number, including her.

She rotates her ankle twice, stands up, returns to position. The set ends with a cross-court spike. The stands erupt, the bench stands up, and the match report reads: outside hitter, 24 points. No line records how many times the left ankle hit the floor.

There are injuries that never appear in a medical report, because they live in a player's eyes. I have covered Vietnamese volleyball across many seasons, sat beside team doctors, and learned something uncomfortable: most of the injuries I have witnessed did not begin with a bad rally. They began with a calendar.

A season with no off-season

Vietnam's women's national team reached the finals of the FIVB Volleyball Women's World Championship for the first time in 2026, hosted by Thailand. That milestone came with a price. To be in Thailand in August, the team had to pass through a chain of events from the start of the year: the AVC Challenge Cup, international friendlies, the SEA Games, and the domestic rounds.

At club level, the National Championship is split into two legs, the first usually falling between April and June, the second stretching into November and December. The Hung Vuong Cup opens the year. The VTV Cup lands in September. Added together, a national-team player can compete continuously from February to December with very short breaks in between.

The overseas group carries a double load. Tran Thi Thanh Thuy, the first Vietnamese hitter to play in Japan's V.League, has a club calendar that overlaps almost entirely with the domestic one. A player in that position can finish her Japanese club season in April, fly home, join the national team camp a few days later, and step into an international tournament in May.

The gap between two competitions is rarely a rest period. It is travel time, time-zone adjustment, medical screening, and re-learning the national team's tactical system. In some developed volleyball nations, that window is written into the plan as a mandatory transition phase of two to three weeks. In Vietnam, it is often compressed into a few days.

The fans' ears and the doctor's ears

Fans remember the rally. Doctors remember the load. The same match, read two different ways.

Based on my experience tracking women's matches in the National Championship, I record the jump count for each position. The average in my sheet: an outside hitter jumps 65 to 90 times in a match lasting four or five sets. A middle blocker jumps less, roughly 45 to 60 times, but most of those are vertical jumps to block, landing on both feet with the body off balance. The libero barely jumps at all, yet executes 40 to 60 digs from a low position, plus hundreds of drops in centre of gravity.

Multiply that by three matches a week and add training sessions, and an outside hitter can rack up more than 900 landings in a single peak month. The force transmitted to the patellar tendon on landing after a jump is commonly estimated at three to five times body weight. For an athlete weighing 65 kg, every contact with the floor is close to 200 kg funnelled through a joint a few centimetres wide.

Sports-medicine centres classify patellar tendon damage among the most common overuse conditions in volleyball, alongside ankle sprains and the shoulder injuries of attacking players.

The ankle has its own story. Most ankle sprains in volleyball happen when a player lands on an opponent's foot near the net. Recognising this, the international volleyball federation amended the rules from the 2026 season to permit the whole foot to cross the centre line under the net. The objective was clear: reduce landings onto the other side's feet.

In Vietnam that rule has long been in force. But a rule cannot solve the rest of the equation, which includes training volume, fixture density and squad depth. A safer legal corridor only reduces the probability of injury within a single rally. It does not reduce the number of rallies a player must perform in a month.

During the pandemic season, when competitions were suspended and teams shifted to home training, I reviewed data from eight clubs, 214 athletes in total. The group that trained at home without a controlled programme returned to competition with a 23 percent higher risk of hamstring pain than the group monitored remotely. I sent that report privately to each medical department rather than publishing it, to avoid turning players into examples.

23 percent of 214 survey responses — every percentage point is a player gritting her teeth. The pandemic did not create the injuries; it simply stripped away the camouflage.

What is missing is not spirit

In Vietnamese volleyball, I rarely meet a player who is lazy in training. I usually meet the opposite.

What is missing sits at the system level. A women's team in the National Championship typically has one or two medical staff for 14 to 16 athletes. Very few clubs employ a full-time strength and conditioning specialist. Load monitoring relies largely on the coach's eye and the player's own sensation. Meanwhile the competitions compress, and relegation or a title race gives every set a very concrete value.

The result is a familiar loop. The squad is thin, so the coach must keep using the starting six. The starters play continuously, and overload markers appear early. The medical staff recommends reducing load, but reducing load means dropping points. The player decides to endure. Then an ordinary rally becomes an injury case.

Injury is a hole in the system, not a personal accident. When a hitter goes down in the fifth set of her third match in a week, the cause is not that landing. The cause lies in the two matches before it, in the morning session, in the decision not to rotate two weeks earlier.

The blind spot of the grit-your-teeth game

One belief is widespread in Vietnamese volleyball: the more you train, the more durable you become. I consider it the most expensive blind spot in the sport.

The body does not accumulate durability in a linear, additive way. Tendons and ligaments adapt to progressively controlled load, together with recovery time. When load rises faster than adaptation, the tissue does not get stronger. It cracks.

The second belief: asking to rest is a sign of weakness. For a player competing for a starting spot, that is socially true. Sitting out one match can cost her position, her bonus, her national-team slot. Our competition format currently rewards endurance and punishes listening to the body.

The third belief: injury is a private matter between a player and her body. Look at the structure of the league and the opposite appears. In some seasons the gap between the champion and the rest is wide enough that strong clubs use their starting six in almost every set. When rewards concentrate in the final standings, nobody has an incentive to rotate. The whole system pushes the load onto a group of seven.

At the same time, Asian international competitions are compressing their calendars and expanding their fields. Every World Championship berth means three to five extra matches in a year. Staying as we are is not a solution that survives contact with the schedule.

What I want to see next season

I stand between the doctor and the player, and I have learned that silence is also a finding. The doctor knows. The player knows. Both have reasons not to speak.

Listening to a player's sigh is more accurate than reading a data sheet. In the medical room after a match, an athlete can smile brightly for an interview, then go completely quiet when the ankle is taped. Exhaustion from keeping someone else's secret is a pain an MRI cannot show.

What I am waiting for is not a thicker report. I am waiting for something small and specific: one National Championship club willing to register 14 players and use all 14 in a set that does not decide anything. A team doctor with veto power who is not treated as someone sabotaging results. A budget line for a load-monitoring device instead of a second foreign hitter.

Vietnamese volleyball is enjoying the best period in its history in terms of results and public attention. That window will not stay open forever. If one well-timed rotation decision could shorten a season's injury list, who in our meeting room will be the first to sign their name?
