| 摘 要： | 根据肌肉收缩滑动学说，当肌肉收缩时，肌纤维间产生滑动摩擦。那么肌纤维相互滑动运动是否产生肌声，肌声与负载量、运动状态、速度等方面存在何种关系已引起关注。作者用声学法研究肱二头肌在负荷下等长、等张收缩、揭示其发声规律。

| Abstract: | According to the sliding theory of muscle contraction,there are sliding friction among musele contraction and among the muscle fibers when muscle contracts.The questions of ohether the sliding motion of muscle fibers produces sound and what relationship there exists between the sound and the load,the state of motion,and the speed of muscle have aroused attention.By using acoustic methods,this paper studied the isotonic and isometric contraction of biceps under load to reveal the characteristics of sound production. |
