Abstract

Water-polo players frequently perform overhead throws that could result in shoulder imbalances. For overhead throws, execution of the 'eggbeater kick' (cyclical movement of the legs) is required to lift the body out of the water. Although a symmetrical action, inter-limb differences in task execution could lead to knee frontal plane projection (FPPA) differences. The present study examined imbalances shoulder and knee FPPA in female players. Eighteen competitive female field players (24.1 ± 5.5 years, 1.68 ± 0.06 m, 72.9 ± 13.3 kg) had their shoulder strength assessed in a shot-mimicking position with a portable dynamometer, standing and seated (isolating the shoulder contribution). Anterior: posterior and shooting: non-shooting shoulder comparison were made. Additionally, players performed a drop jump. Knee FPPA was recorded from digitising and comparing the frames just before landing and at stance phase. During standing, players exhibited higher shooting: non-shooting asymmetry (p = 0.032) in the anterior contraction direction, while during seated the shooting shoulder anterior: posterior asymmetry was higher (p = 0.032). Interlimb knee FPPA asymmetry was higher in the stance phase (p = 0.02). Despite the overhead throwing and egg-beater demands impacting differently on each limb, considerable asymmetries do not develop, suggesting the overall training requirements (e.g. swimming, resistance training) were sufficient to maintain the asymmetry within desirable limits.

女子水球运动员的上肢肌肉力量和膝关节额平面投影角不对称。
水球运动员经常进行高抛动作,这可能会导致肩部失衡。在进行高抛时,需要执行 "打蛋踢"(双腿的周期性运动)将身体抬出水面。虽然这是一个对称的动作,但在执行任务时,肢体间的差异可能会导致膝关节额面投影(FPPA)的差异。本研究考察了女运动员肩部和膝部 FPPA 的不平衡。18 名竞技女田径运动员(24.1 ± 5.5 岁,1.68 ± 0.06 米,72.9 ± 13.3 千克)使用便携式测力计对其肩部力量进行了评估。进行了肩部前:后和投篮:非投篮的比较。此外,运动员还进行了落点跳跃。通过对着地前和站立阶段的帧进行数字化和比较,记录了膝关节 FPPA。在站立时,运动员在前收缩方向上表现出更高的投篮:非投篮不对称性(p = 0.032),而在坐姿时,投篮肩的前收缩:后收缩不对称性更高(p = 0.032)。在站立阶段,肢间膝关节 FPPA 不对称程度更高(p = 0.02)。尽管高空投掷和打蛋的要求对每个肢体的影响不同,但并没有出现严重的不对称,这表明整体训练要求(如游泳、阻力训练)足以将不对称保持在理想的范围内。
