人体运动过程中,除了总要受到重力作用外,大多数动作形式是人体与外界物质相互作用的结果。特别是最常见的蹬地力所引起的支撑反作用力是绝大多数动作项目的动力来源。因此,定量地记录蹬地过程的瞬态蹬地力或支撑反作用力,对研究人体运动的动力学特征,进行运动技术诊断极为有益。这种记录,可记录在一维单向空间所受的力和二维平面空间所受的力,也可记录在三维立体空间所受的力。其中,后者能反映人体运动过程的真实三维立体空间,研究问题的意义较大。目前,我国的运动生物力学研究已着手应用多
In the course of human body movement, most of the action forms are the result of the interaction between the human body and the external world besides the total force of gravity. In particular, the most common pedaling force caused by the support reaction is the driving force of most action items. Therefore, it is very beneficial to diagnose the kinetic characteristics of human body movement and diagnose sports skill by quantitatively recording the transient pedaling force or supporting reaction force during pedaling. This kind of record can record the force in one-dimensional one-way space and the force in two-dimensional plane space, and also record the force in the three-dimensional space. Among them, the latter can reflect the real three-dimensional space of the process of human movement, the significance of the research problem. At present, the research of sports biomechanics in China has started to apply more
