陕西省优秀跆拳道运动员膝关节屈伸肌群等速测试与研究

Constant Speed Test and Analysis of Shaanxi Province Excellent TKD Athletes Knee Joint and the Analysis of the Attacking Technique

采用ISOMED2000获得陕西省优秀跆拳道运动员膝关节等速收缩的生物力学特征。右膝关节屈肌群等速离心收缩峰值力矩出现时的关节角度在152.81-159.33°之间,伸肌群等速离心收缩峰值力矩出现时的关节角度在113.01-108.61°之间。膝关节屈肌伸群向心收缩,速度在240°/s时相对力矩梯度达到最大,右膝屈肌群最大值29.62 N.m/s.kg,伸肌群最大值为51.42 N.m/s.kg。

This study adopts isomed2000 system to get the biomechanical characteristics of excellent TKD athletes＇ knee muscle group. The corresponding knee joint flex muscle group Isokinetic eccentric contraction angle angle range of the peak torque coming is between the 152.81- 159.33° ,The corresponding knee joint exertion muscle group concentric eccentric contraction angle angle range of the peak torque coming is between the 113.01-108.61° ;the relative force moment grade peak coming when the knee joint flex and extent muscle group is 240°/s, the relative force moment grade peak of the right knee flex muscle group is 29.62 Nm/s.kg, the relative force moment grade peak of the right knee extent muscle group is 51.42 N.m/s.kg.
