对跨栏跑的速度和速度训练的研究

要提高跨栏专项成绩，就必须解决好栏上的过栏速度和栏间平跑速度。其中过栏速度靠提高起跨腿蹬地速度、摆动腿动作速度、起跨腿提拉速度和下栏转为栏间跑速度，栏间乎跑速度靠提高栏间步频为主。指出平跑速度、过栏速度的重要性，并对二者提出了科学的训练方案。

A study on the speed of running between the hurdles and the training of the speed

To promote hurdling performances,we must raise the speed of clearing and of steady running between the hurdles.To raise the speed of hurdle clearing,speed of driving off the ground,swing leg,takeoff leg,cut down to running between the hurdles must be quickened.To raise the speed of steady running between the hurdles,frequency of stride must be accelerated.This paper points out that steady running and the speed of clearing the bar are two decisive factors in hurdling.It also proposes appropriate training methods for promoting speed of steady running and clearing the bar.
