不同角速度下男子跳远运动员髋关节肌群等速向心收缩的肌力研究

A Study on the Muscle Strength of Hip Joint Muscles Centripetal Contraction of Male Long Jumper under Different Argles

利用Cybex-770等速肌力测试与康复系统,以150°/s、90°/s、60°/s3种角速度对17名优秀跳远运动员起跳腿髋关节进行等速向心收缩测试。获得了相应的等速向心收缩的相对峰力矩、相对总功、相对平均功率和峰力矩屈伸比的指标,并结合项目特点,力争为跳远训练提供更科学的服务。

We test hip joint of supporting leg in concentric contraction, under the angular velocity of 150°/s,90°/s, 60°/s,by using Cybex- 770 isokinetic and rehabilitation instrument, we obtain the norms,such as PT/BW, TW/BW, AP/BW, F/E, and combine its characteristic. The results provide the scientific base to improve the event specific strength training and technique for coach.
