摘要：在短跑途中跑中，前蹬动作既有制动(维持人体动态平衡)作用，又有后蹬前的储能作用。所以，前蹬动作的质量在短跑中至关重要。在短跑训练中要重视腿在体前的活动状态，即加大腿在体前活动的幅度和力度有助于缩短前蹬时间，减小制动冲量；同时提高了后蹬时的所需能力而双赢。

Abstract: In the dash running the ahead driving leg action not only keeps balance the dynamic body but also save the power of the after driving leg. So the quality of the ahead driving leg is very important in the dash.People must recognize the leg's active estate that add;the breadth and force of the leg's active in front of the body in the training because it will administer to shorten time of the ahead driving leg reduce impact power of the after driving leg.
Key words: dash； running； the ahead driving leg； impact power
