陕西省优秀跆拳道运动员髋关节屈伸肌群等速测试与研究

摘要

Abstract：The paper aimed to obtain the biomechanical characteristics of isokinetic contraction by using ISOMED2000 system to test the hip joints of Shaanxi elite taekwondo athletes. The joint angle was between 133.7° and 140.2° when the isokinetic eccentric contraction of right hip flexors reached peak torque and between 121. 2° and 106.3° when that of right hip extensors reached peak torque. It is when the concentric and eccentric contraction speed of hip flexors and extensors was at 240°/s that the relative torque gradient reached the maximum.%采用ISOMED2000获得陕西省优秀跆拳道运动员髋关节等速收缩的生物力学特征。右髋关节屈肌群等速离心收缩峰值力矩出现时的关节角度在133．7°-140．20之间，伸肌群等速离心收缩峰值力矩出现时的关节角度在121．2°-106．30之间；髋关节屈伸肌群向心收缩、离心收缩速度在240°／s时相对力矩梯度达到最大。
