起跨腿的足部在过栏前达到其飞行弧线的顶点。

The foot of the lead reaches its apex of the flight curve prior to clearing the hurdle .

起跨腿，作用应相当于蔓延腿，在过栏时必须充分伸展。

The take-off leg , which will serve as the " trail leg ", must fully extend at take-off .

跨栏运动技术比较复杂，特别是起跨腿在摆越过栏时，需要速度快、技术娴熟。

The skill of hurdle race training is complex , especially athlete need high speed and skilled when across the hurdle .

当起跨腿的大腿部分平行于跨栏时，动力转向自然伸展的小腿。

When the thigh of the lead leg drives up to a position parallel to the track , momentum is transferred to the lower leg , which extends naturally .

发现在跨栏跑初期教学中，在运用传统的教学方法的同时强调起跨腿折叠、外展，并在适宜的时机进行提拉能起到良好的教学效果。

It was found that when applying the traditional teaching method , emphasizing the folding and stretching outwards of the takeoff leg at the proper time would obtain good teaching effect .

摆动腿下压的时机始于身体重心位于栏上瞬时，大约经过0.031s的时间，起跨腿加速向前提拉。

Swing the opportune moment that leg descend press to begin from the body center of gravity to be located on the hurdle , about pass by 0.031 seconds of time , rise to across the leg to accelerate forward lift to pull .
