体操动作按其性质可分为两类:一类是动力性的摆动动作,一类是用力动作.摆动动作主要是利用身体重力和惯性来完成的,而用力动作主要是利用肌拉力来完成的.从生理学的观点来比较,摆动动作的特点在于肌肉长度变化的速度,而用力动作的特点主要在于肌紧张的程度.但是,上述的分类无疑是一种假设.因为任何一个摆动动作不但有肌紧张的因素,而且也有肌拉力的因素;而用力动作,那怕是使身体由一个部位转移到另一部位的动作也好,如果没有肌长度的变化也是无法完成的.静力动作另属独特的一类.所谓静力动作,就 Gymnastic movements according to their nature can be divided into two categories: one is the power of the swing, one is the force of action. Swing is mainly the use of body weight and inertia to complete, but the main force is the use of muscle tension to complete From the physiological point of view, the swing movement is characterized by the speed of muscle length changes, and the characteristics of forced movements are mainly due to the degree of muscle tension, but the above classification is undoubtedly a hypothesis, because not only any one swing movement has muscle Nervous factors, but also the factors of muscle tension; and forceful action, even if the body is transferred from one part to another action Ye Hao, if there is no change in muscle length can not be completed. The so-called static action, on
