对于蹲踞式起跑,一般都知道 最后听枪声起动时,双手推离地面,但是对于初学者及13～17岁少年的训练中,运用这些知识去套用,使训练中带来了许多的失误。例如:在枪响之后,运动员的身体抬高过早,腿部的后蹬力量过于向上而不向前等,直接或间接的导致了运动员的速度发挥较晚或根本就发挥不出来,就到达了终点,以至不能使成绩得到提高。 For crouching starters, it is generally known that at the end of a gun start, both hands are pushed off the ground. However, for beginners and 13 to 17 years of age, applying this knowledge to practice has brought many mistakes in training. For example: after the gunshots, the athlete’s body is raised too early, the leg’s backrest strength is too upward and not forward, etc., directly or indirectly lead to the athlete’s speed play late or simply can not come out to reach The end, and can not make the grade improved.
