一、直线性放松跑的一个重要作用是增强神经系统对肌肉的控制力,增加主动肌的收缩力量,减少对抗阻力。在快速跑中,如果偏离原来的直线路径,学生必须消耗一定能量以控制运动方向,这就会增大肌肉对抗阻力,使放松效果大打折扣,因此,要强调放松跑或放松阶段的直线性。 First, the linear relaxation Run an important role is to enhance the nervous system on muscle control, increase the contraction of active muscle strength, reduce resistance. In fast running, if you deviate from the original straight path, students must expend a certain amount of energy to control the direction of movement. This will increase muscle resistance and greatly reduce the relaxation effect. Therefore, it is necessary to emphasize relaxation of straightness during relaxation or relaxation.
