起跑是为了在最短的时间内获得最大的水平加速度,在后蹬力一定的条件下,获得的支撑反作用力不变,如果跳起,则说明蹬地后产生的竖直分力较大,而水平分力较小,则相对减小了水平加速度。
The starting point is to obtain the maximum horizontal acceleration in the shortest period of time. The obtained support reaction force is constant under the condition that the rear pedaling force is constant. If the pedaling force is raised, the vertical force generated after pedaling is larger. The smaller the horizontal component, the relative reduction of the horizontal acceleration.
