股四头肌肌力训练结合踝关节稳定性训练对跳跃落地动作膝关节生物力学特征的影响
he Biomechanical Influnce of Quadriceps Strength and Ankle Stability Training on Knee in Jumping Test
研究目的:探究单纯提高股四头肌力量和同时提高股四头肌力量及踝关节稳定性是否会改善跳跃落地过程中中膝关节内收力矩以及其他生物力学指标，以及明确相较于单纯提高股四头肌力量，股四头肌力量和踝关节稳定性同时提高是否更具优势。方法：对18位青年女性进行为期6周的股四头肌力量结合踝关节稳定性训练或单纯股四四头肌力量训练，实验前后运用红外高速运动捕捉系统（Motion Analysis Raptor-4，USA）和三维测力台（Kistler 9281CA,Switzerland）进行运动学和动力学数据采集，并运用spss软件对采集的数据进行分析。结果：是否训练和训练方法对落地缓冲过程中内收力矩峰值以及外展力矩峰值产生了交互效应（p=0.026，p=0.039）。结论：(1) 股四头肌力量结合踝关节稳定性训练以及单纯股四头肌力量训练会造成落地时膝关节膝关节内收力矩的增加，不适用于健康青年女性以预防膝关节骨性关节炎为目的的运动干预。(2)股四头肌力量结合踝关节稳定性训练相较于单纯股四头肌力量训练，对跳跃落地时膝关节最大屈曲角、外展力矩峰值产生的不同效果，但这种差异并无临床意义。
Objective. To assess the biomechanical effectiveness of quadriceps strength and ankle stability training and single quadriceps strength training on knee and make sure the differences between them. Methods. Let 18 young women take 6 weeks quadriceps strength and ankle stability training or single quadriceps strength training. And before and after, kinemics and kinetics dates were analysed and compared. Findings. There is a significantly change that both quadriceps strength and ankle stability training and single quadriceps strength training made in knee adduction moment. Conclusions. Both quadriceps strength and ankle stability training and single quadriceps strength training made a increase in knee adduction moment.And these exercise therapys are not suitable for young women to prevent the incidence of knee osteoarthritis.
