摘要
对有关跑的动力不是蹬地反作用力的种种新观点进行了剖析,本文赞同跑“动力是蹬地反用力”这一传统理论,而各种新观点仅仅是对跑动时运动器官和肌肉活动的表象描述,其错误根源在于混淆了内力和外力的内涵、作用效果和相互转化关系。
In this article,the new views that the motive force of running is not the eccentric thrust of reaction are analyzed thoroughly.Result show the is traditional theory:the motive force of running is the eccentric thrust of reaction is still right,and the new opinion only a superficial descriptions of the movement of motion organs and mixing up the intension,the action effect of the internal and exernal force and transform relationship between them.
