在人类基本活动中各单个关节对整个动作做功贡献的研究尚不多见,而该研究对人类运动分析的研究及实践都是非常重要的。研究者常常把某一肌肉群作为某一动作的主要肌肉群,如在许多文献中把股侧肌作为某一运动的主要肌肉(萨姆逊等、1979)。一块肌肉对整个力量输出或所做的功的贡献大小对如何精确客观地选择某一肌肉作为整个动作的代表是必要的,且对教练员、康复医生如何设计训练方案也是很有价值的。
In the basic activities of human beings, the contribution of each individual joint to the whole movement is rare, and the research is very important to the research and practice of human movement analysis. Researchers often use a certain muscle group as the main muscle group of a certain movement, as in many literatures using the lateral muscle as the main muscle of a certain movement (Samson et al., 1979). The contribution of a muscle to the total power output or work done is necessary to accurately and objectively select a muscle as a proxy for the entire action and is also valuable to coaches and rehab doctors in designing training programs.
