正式比赛或训练后进行的各种身体练习,称为整理活动。整理活动是训练课不可缺少的身体练习部分。在剧烈运动训练过程中,全身血液发生明显的重新分配,安静状态主要供应内脏的血液量在运动中转移到骨骼肌,而骨骼肌的舒缩活动产生所谓肌肉泵作用,促进骨骼肌中的血液及时回流到心脏,以保证足够的心输出量。如果在剧烈运动后立即停止运动,下肢肌肉中的血液失去肌肉泵的作用而发生回流障碍,回心血 All kinds of physical exercises after a formal match or training are called finishing activities. Organizing activities is an indispensable training part of the body exercises. During strenuous exercise training, there is a clear redistribution of whole body blood. Quiet state mainly supplies visceral blood which is transferred to skeletal muscle during exercise. Skeletal muscle contraction and contraction produce so-called muscle pump to promote the blood in skeletal muscle Timely back to the heart, in order to ensure adequate cardiac output. If you stop exercising immediately after strenuous exercise, the blood in the lower extremity muscle loses the function of the muscle pump and a reflux disorder occurs
