摘要
为了更深入理解下肢关节在纵跳过程中的力学关系,本文针对高、低两组纵跳成绩被试在有、无摆臂状态条件下展开运动生物力学测试。研究结果显示,高水平组在关节力矩、瞬时功率方面均优于低水平组,同时认为下肢肌肉力量特征比动作技术对最终纵跳高度起更重要作用。
The aim of this study was to investigate the contribution made by the lower limb joints to vertical jump performance by good and poor performers of the vertical jump. Two groups of players were selected who were found to be good and poor jumpers, respectively. The jump performance was recorded simultaneously by means of a force platform and a Qualysis motion analysis system. Generally, better jumpers demonstrated greater joint moments, power at the ankle, knee, and as a result jumped higher under both conditions. It appears that the superior performance of the better jumpers was due to greater muscle capability in all lower limb joints rather than to technique.
