“蹲踞式”起跑是快速跑技术构成的一个重要环节,是影响快速跑成绩的一项主要技术要素,是快速跑技术教学的重点、难点之一。就“蹲踞式”起跑技术的目的和任务而言,是指应用符合人体重心移动规律,采用某种身体姿势,使人体摆脱静止状态获得最大动能的行为方式。因此,能否掌握和 “Squatting” starting is an important part of the composition of rapid running technology, which is one of the major technical factors that affect the performance of rapid running. It is also one of the key and difficult points of rapid running technical teaching. In terms of the purpose and task of “squatting” start-up technique, it refers to the behavior of using a body posture that is in conformity with the law of movement of the center of gravity of the human body to get the human body out of its resting state to obtain the maximum kinetic energy. Therefore, we can grasp and
