在许多运动项目中,肌肉力量是决定运动成绩的最重要身体素质之一。完成各种体育练习时,要求肌肉收缩的值和特点都不尽相同:即当肌肉进行一定程度的快速收缩时,在有些情况下,主要是发展等长力量(静力)的能力;而在另一些情况下,则主要是发展等动力量(动力)的能力。因此,我们主要是想研究一下各种力量训练对肌肉收缩的上述特性曲线所起的作用。现在,力量训练的方法可分为三类:等长训练和两种不同形式的动态性训练——等张训练和等动训练。肌肉力量训练中的等长训练和等张训练早已在运动实践中采用了,而发展力量的动态性等动训练则是
In many sports, muscle strength is one of the most important physical qualities that determine athletic performance. When performing various physical exercises, the values and characteristics of muscle contraction are all different: that is, when the muscle undergoes a certain degree of rapid contraction, in some cases it is mainly the ability to develop isometric strength (static force) In other cases, it is mainly the ability to develop isokinetic momentum (motivation). Therefore, we mainly want to study the effect of various strength training on the above characteristic curve of muscle contraction. Now, the methods of strength training can be divided into three categories: isometric training and two different forms of dynamic training - isometric training and isokinetic training. Equal-length training and isotonic training in muscle strength training have long been used in sports practice, while dynamic training in the development of strength and other training exercises
