蹲踞式起跑技术的关键，在于如何把起动时产生的后蹬力量充分作用到加速跑当中去，使起动速度能够迅速地转化到位移速度上来。但是，在蹲踞式起跑教学与训练中，许多短跑运动员经常会出现第一步距离过大或第一步落地点偏向于前腿一侧的现象。致使起跑后身体产生制动、重心不稳 The key to squat-type start-stop technology lies in how to fully apply the force of rear pedal generated during starting to accelerate running so that the starting speed can be quickly converted to the displacement speed. However, many squad runners often experience first-step over-distance or first-leg bias toward the front leg during squat-start teaching and training.
