运动实践中,除了投掷等为数不多的项目外,如何发展力量而不同时增加过多的体重常常是教练员和运动员所关心的问题。肌比力(每单位横断面积上肌肉的力量)正是反映这个问题的一个生理学指标。了解一百多年来科学工作者对这个问题的研究以及近几十年来的进展概况,提出尚待继续探讨的问题,显然是有意义的。 In sports practice, except for a few projects such as throwing, it is often a matter of concern to coaches and athletes how to develop strength without increasing excess weight at the same time. Muscular strength (muscle strength per unit cross-sectional area) is a physiological indicator of this problem. It is obviously significant to understand the research conducted by scientists on this issue for more than a hundred years and the progress made in recent decades. It is obviously meaningful to raise the issue that remains to be explored.
