因为采用有创性肌肉活检法来判断肌纤维类别不易为人们所接受,本研究的目的是将从正常研究对象所取得的一系列非损伤性生理学肌肉测验的参数与从股外侧肌(VL)活检所得的纤维类型分布的相关性,得到一个回归方程式来区分Ⅰ型和Ⅱ型纤维。其功能测定应用Cybex试验来测量:①最大力矩;②不同角速度时的功率输出;③膝伸肌的最大功率和达到最大功率时的特殊角速度;④膝伸肌的抗疲劳度。 Because the use of invasive muscle biopsy to determine muscle fiber category is not easily accepted, the objective of this study was to compare the parameters of a series of noninvasive physiological muscle tests obtained from normal subjects with those obtained from the lateral femoral muscle (VL) biopsy The correlation of the resulting fiber type distributions gives a regression equation to distinguish type I and type II fibers. Its function is measured using the Cybex test to measure: the maximum torque; the power output at different angular velocities; the maximum power of the knee extensor and the specific angular velocity at maximum power; and the fatigue resistance of the knee extensor muscle.
