摘要
根据由物体－弹簧和粘带器组成的系统作自由振荡时，其振荡频率是弹簧的弹性刚度和粘滞器粘滞系数等参量的函数的原理，介绍了一种简便易行的测量人体活体肌肉弹性的方法。由计算得知，在低负载时，肌肉张力是决定肌肉弹性刚度大小的主要因素；但随着负载的增加，肌肉的总弹性刚度趋向于由肌腱的弹性刚度来决定。
A system composed of a body-string and a damper was made, based oh the theory that when itoscillates freely, its vibrational frequency is the function of those parameters e- g. the elastic stiffness of the string and the viscous coefficient of the damper. That is a simple and convenient method for measuring the muscular elasticity of the human body. It was calculated that in sma1l loading the muscular tension was a main factor that affected muscular elastic stiffness. However, with the increase of the load the total muscular elastic stiffness tended to be determined by the elastic stiffness of the tendon.
