运动员膝关节等速肌力测试研究的进展综述

The progress summary of Constant Speed Myo-strength Test research about Athlete′s knee joint

通过文献资料法、分析比较法对等速肌力研究的现状进行了分析研究,研究表明,膝关节肌群伸肌峰力矩均大于屈肌峰力矩;膝关节离心收缩的平均功率也明显大于向心收缩;我国运动员膝关节屈伸肌峰力矩比值,均值为0.66,最大值0.84(极个别运动员);而国外运动员的水平普遍在0.80-1.0之间;不同级别的运动员膝关节肌力的主要差异在快速力量方面,因此提高肌肉快速力量是体能主导类项群提高成绩的主要途径。

with the method of literature compartion, The research indicated that ： the peak moment of force about the knee joint myo - group extensor is bigger than the flexor. It＇s average gentrifugalism contraction power is also bigger than the centripetal contraction obviously, the average value of ratio about Flexor and extensor is 0.66 , maximum value 0.84 （ extremely individual athlete） in our country . The main way to enhances the result of Physical ability leadership class item of group is enhances the fast strength of muscle because the main difference is fast strength of different rank athlete .
