一、前言短跑的协调放松能力是从多种因素在短跑运动中的综合作用,是多个环节紧密结合的一个体系。从不同的角度可以得到不同的解释。从力学角度,是指主动肌与对抗肌的高度协调能力,转换的灵活性,使动作幅度获得最佳的使用价值和经济性。从生理学角度理解,肌肉的放松是指肌肉的舒张,而肌肉的紧张指肌肉的收缩。人体的一切运动都是在大脑皮层 First, the preamble Sprint coordination and relaxation ability is a combination of a variety of factors in the sprint movement, is a combination of multiple links a system. Different interpretations can be obtained from different perspectives. From a mechanical point of view, refers to a high degree of coordination between the active muscle and the antagonist muscle, the flexibility of conversion, so that the range of motion to obtain the best value for money and economy. From the physiological point of view, muscle relaxation refers to the relaxation of the muscles, and muscle tension refers to the contraction of the muscles. All human movement is in the cerebral cortex
