Vietnam women's volleyball declines in one year: diagnosis from overload, injuries and a deciphered style

Only one year after winning the AVC Cup, winning the SEA V.Cup and reaching the World Championship, Vietnam women's national volleyball team entered the 2026 season with a downward run on every stage. At the 20th Asian Games in Aichi-Nagoya, Japan, the team finished 7th, below its top-four target. The AVC Cup ended with third place and no final. The SEA V.Cup saw Vietnam finish second in the first stage and then lose 0-3 in the second. The Asian Championship produced only one win. Four tournaments, four below-standard results, forming a signal that cannot be seen as coincidence. The list of losses did not only include China, Japan or South Korea. Indonesia beat Vietnam twice. The Philippines and Kazakhstan also caused surprises. These unexpected losses point to a prolonged slump rather than a single accident. Looking at the squad changes, Vietnam lost three to four key starters at the same time for reasons outside form. Nguyen Thi Trinh was absent for family reasons. Vi Thi Nhu Quynh left for personal reasons. Hoang Thi Kieu Trinh was injured, and Nguyen Thi Uyen had a serious injury. Coach Nguyen Tuan Kiet had to use Doan Thi Xuan, Thanh Thuy and Uyen in the opposite position. Moving an outside hitter to the opposite role lowers attacking efficiency and weakens right-side blocking. Captain Tran Thi Thanh Thuy scored 36 points at the Asian Games but with quite low efficiency. Before that, she played for Gunma Green Wings in Japan, returned to VTV Binh Dien Long An, and then ran four national-team tournaments from January. When a key player carries such a long schedule, 36 points is not simply a form issue; it is a sign of overload. The problem lies in workload management, not individual talent. Tactically, the most visible detail is that attacks from positions 4 and 2 constantly met the block. When the wings were neutralized, the ball was forced toward the middle. As a result, a middle blocker like Bich Thuy became one of the team's highest scorers. In a healthy fast-attack system, the middle is the threat that opens space for the wings. When the middle becomes the main escape route, the connection between the setter and the wing attackers has broken. Vietnam did not necessarily lose because of a lack of power. The team became easy to read: slow set tempo, predictable distribution, and blockers ready in time. This is a fixable issue through faster setting, more varied distribution and sharper wing angles. At the same time, we must be careful with data. The only individual stat cited is Thanh Thuy's 36 points, without attempts, perfect-pass rate or blocking numbers. Data never lie, but the person who selects the data knows very well how to lie. One number is not enough to judge the whole team. From another angle, this is not a collapse of the foundation. The decline comes from three reversible factors: missing players, an overloaded calendar and a deciphered style. More worrying is the speed of improvement of Indonesia, the Philippines and Kazakhstan. Teams once below Vietnam have closed the gap while Vietnam rebuilt its lineup. The position of second-best team in Southeast Asia behind Thailand is no longer safe. The role of coach Nguyen Tuan Kiet has been questioned at important moments. Losing to lower-ranked teams several times usually reflects in-match collapse, not just player quality. But criticism should be based on tactical evidence, not turned into unfocused pressure on one person. From the tournaments I have followed, the team has not lost its character, but it has lost its synchronization. Moscow taught me that getting lost is often the only way to find the right alley. This losing season can be a backward map for the coaching staff. The veterans Kim Thoa, Bich Thuy and Khanh Dang did not peak at the same time. The next generation has not been tested at international level. Public pressure is high because expectations are still anchored to the golden era. A team that once won the AVC Cup and the SEA V.Cup is always compared to its own past. That comparison is unfair to the current depleted squad. The positive side is that most causes can be reversed. If the missing players return, the schedule is split more carefully, and the setter has more attacking options, one bad year can become a wake-up call instead of the start of long decline. The biggest task is succession planning. The golden generation of 2026-2026 cannot last forever. Fans do not need a stadium; they need something to believe in. That is why I write. Next season, the question is not whether Vietnam can beat Indonesia again, but whether the team dares to rebuild from the foundation.
