| 摘 要： | 研究表明 :①随着助跑速度的逐渐加快 ,运动员下肢肌承受的冲击载荷也随之增大。当助跑速度所造成的冲击载荷在运动员下肢肌的承受能力的范围内时 ,运动员能够通过下肢肌的积极主动的退让缓冲来迅速平衡外部载荷 ,产生良好的缓冲和蹬伸效果。②当助跑速度超出了运动员的适宜助跑速度的范围时 ,运动员不能通过积极主动的退让缓冲来迅速平衡外部载荷 ,缓冲和蹬伸效果下降。

| Abstract: | The findings indicate that:firstly,along with quickening the run up speed gradually,the received impact workload of jumpers' leg muscles augments.When the impact workload of run up speed is within the range of the jumper leg muscles' endure ability,jumpers can balance the exterior workload rapidly by active concession and buffer bringing favorable buffer and stretch effects.Secondly,when the run up speed goes beyond the proper speed range,jumpers can't balance the exterior workload rapidly by active concession and buffer,and the buffer and stretch effects decline. |
