BACKGROUND
Although a knee valgus position is related to the increase in injury risk in volleyball players, there is a lack of studies on the relationship between knee valgus and vertical jump (VJ) performance. Hence, the aim of this study was to investigate the effects of a postural exercise program on VJ height in young female volleyball players with knee valgus.
METHODS
This pilot study included 19 young female volleyball players divided into the following groups: the Valgus Experimental Group (VEG); the Valgus Control Group (VCG); and the Neutral Control Group (NCG). All three groups carried out the same volleyball training program. In addition, only the VEG underwent a 3-month postural exercise program of 30-45 min/session, twice/week. VJ performance was measured through the Sargent test before (T0), at 6 weeks (T1), and at 12 weeks (T2).
RESULTS
A significant effect from T0 to T1 ( = 0.0017) and from T0 to T2 ( = 0.0001) was found in the VEG. No significant differences were found over time in the VCG and in the NCG.
CONCLUSION
An integrated postural exercise program might lead to a more balanced muscle efficiency inducing athletes to obtain a higher VJ performance.
背景
虽然膝关节外翻与排球运动员受伤风险增加有关，但目前缺乏关于膝关节外翻与垂直跳跃（VJ）表现之间关系的研究。因此，本研究旨在探讨姿势练习方案对膝关节外翻的年轻女性排球运动员 VJ 高度的影响。
方法
这项初步研究纳入了 19 名年轻女性排球运动员，分为以下几组：外翻实验组（VEG）；外翻对照组（VCG）；中立对照组（NCG）。三组均接受相同的排球训练计划。此外，仅 VEG 进行了为期 3 个月、每次 30-45 分钟、每周两次的姿势练习方案。在 T0（基线）、T1（6 周）和 T2（12 周）时通过 Sargent 测试测量 VJ 表现。
结果
VEG 组从 T0 到 T1（ = 0.0017）和从 T0 到 T2（ = 0.0001）的差异均具有统计学意义。VCG 和 NCG 组在各时间点的差异均无统计学意义。
结论
综合姿势练习方案可能会导致肌肉效率更加均衡，从而使运动员获得更高的 VJ 表现。
