【摘要】：结合网球运动项目特征,对其运动中的复合动作模式的生物力学特征进行分析,旨在探讨网球运动员踝关节运动的动力学特征,改善和提高日常训练的有效性和科学性,预防和减少运动中踝关节损伤的发生。本研究主要运用三维运动影像捕捉系统、三维测力台、表面肌电仪,同步采集受试者运动中的运动学、动力学、肌电学数据。得到:跑动急停向前起动跑、跑动急停侧向起动跑、跑动急停转身180°起动跑产生最大跖屈力矩分别为(1.818±0.246)N·m、(1.93±0.235)N·m、(2.21±0.32)N·m;在三种动作模式中,踝关节外翻的最大力矩分别为(0.392±0.023)N·m、(0.26±0.007)N·m、(0.16±0.03)N·m;最大外旋力矩分别为(0.139±0.036)N·m、(1.03±0.31)N·m、(0.403±0.021)N·m。结果表明:三种动作模式中,最容易造成踝关节损伤的动作是跑动急停侧向起动跑,对于网球运动员来说,在加强踝关节肌肉力量训练的同时还应该加强踝关节肌肉群的伸展性、灵活性、稳定性的训练。
[Abstract]:Combined with the characteristics of tennis events, this paper analyzes the biomechanical characteristics of the complex movement mode in tennis, in order to discuss the dynamic characteristics of the tennis players' ankle motion, and improve the effectiveness and scientific nature of the daily training. To prevent and reduce the occurrence of ankle joint injury during exercise, this study mainly uses three-dimensional motion image capture system, three-dimensional force table, surface electromyograph, and synchronously collects the kinematics and dynamics of the subjects in motion. Electromyoelectric data. The results showed that the maximum metatarsal flexion torque of running, running, running, running, running, running, running, running and running, was 1.818 卤0.246 Nm, respectively, 1.93 卤0.235N / m = 2.21 卤0.32nm. in the three action modes, the maximum metatarsal flexion torque was 1.818 卤0.246Nm ~ (-1) and 2.21 卤0.32 (n / m) respectively. The maximum torques of the valgus of the ankle joint were 0.392 卤0.023 Nm, 0.26 卤0.007, respectively, 0.16 卤0.03Nmand 0.139 卤0.036N, respectively. The results showed that, among the three action modes, the most likely to cause the ankle joint injury was to run on the side. For tennis players, While strengthening the strength training of ankle muscles, we should also strengthen the training of extensibility, flexibility and stability of ankle muscles.
