摘要
摘要:
目的 探索跆拳道后横踢动作膝关节的肌肉发力特征.方法 通过DaeDo电子打分系统并配合Vicon光学动作捕捉系统、Kistler三维测力台,采集 12 名高水平竞技跆拳道运动员后横踢动作运动学和动力学数据,通过OpenSim软件进行模拟,计算膝关节的肌肉力、关节力矩、关节刚度及肌肉协同工作模式.结果 进攻腿在提膝和击打时刻膝关节冠状轴力矩较大,矢状轴力矩在击打时刻达到峰值;支撑腿在提膝时刻膝关节冠状轴力矩最高,矢状轴力矩在击打时刻达峰值.进攻腿半膜肌和股二头肌长头在击打时段力量较大,支撑腿半膜肌和腓肠肌内侧头则在回收时段力更大.跆拳道后横踢动作中存在 5 种肌肉协同模式.结论 后横踢动作运动员执行后横踢动作时,进攻腿、支撑腿的膝关节肌群肌肉力、关节力矩等存在较大差异,肌肉之间存在复杂的协同关系.

Abstract:
Objective To explore the muscle force characteristics of the knee joint during a Taekwondo roundhouse kick in Korea.Methods Kinematic and dynamic data from twelve elite Taekwondo athletes were collected using the DaeDo electronic scoring system,Vicon optical motion capture system,Kistler three-dimensional force plates.The OpenSim software was used to simulate these movements and calculate the muscle forces,joint torques,joint stiffness,and muscle coordination patterns of the knee.Results During the knee-lifting and striking phases,the coronal torque of the knee joint in the attacking leg was significant,and the sagittal torque peaked during the strike.For the supporting leg,the highest coronal torque of the knee joint occurred during knee lifting,with the sagittal torque reaching its peak during strike.In terms of muscle activity,the semimembranosus and long head of the biceps femoris in the attacking leg exerted greater force during the striking phase,whereas the semimembranosus and medial head of the gastrocnemius in the supporting leg were more active during the recovery phase.Five muscle synergy patterns were observed during the Taekwondo roundhouse kick.Conclusions Significant differences were found in the muscle forces and knee joint torques of the attacking and supporting legs when athletes performed the roundhouse kick,and there was a complex muscle synergy.
