速度对膝关节屈肌和伸肌等速离心收缩力矩的影响

The influence of velocity on isokinetic eccentric torque of hamstrings and quadriceps

目的确定运动速度对离心收缩测试的影响,为进一步深入研究提供客观依据。方法对20例健康人膝关节进行等速离心收缩测试,用统计学方法观察不同速度下膝关节屈肌和伸肌峰力矩、相对峰力矩和屈肌/伸肌比值的变化。结果速度对膝关节屈肌和伸肌峰力矩和相对峰力矩影响显著,对屈/伸比值的影响不显著。结论离心等速测试和训练过程中,必须考虑速度的因素。

Objective To observe the influence of velocity on isokinetic eccentric torque of hamstrings and quadriceps.Method20normal males were tested by BIODEX is okinetic test and their peak torque(PT),peak torque to body weight (PT /BW)and F /E value were analyzed.Results It was found that PT and PT /BW were obviously influenced by velocity but th ere is no significant influence on F /E value.Conclusion Velocity must be considered during i sokinetic eccentric test.
