采用文献资料法、逻辑分析法、专家访谈法等研究方法对110m栏中的跨栏步技术动作和男子100m运动中途中跑的一个单步进行对比分析与研究,结果显示:支撑腿着地瞬间,刘翔的着地角相对小于博尔特的着地角,两者之间呈显著性差异;下栏着地瞬间,110m栏在着地角度比100m大10°左右,着地点与身体重心投影点距离也较100m近,但着地瞬间躯干前倾角110m栏与100m该指标的大小几乎接近。
By using the methods of documentation, logic analysis and expert interviews, the comparative analysis and research on the hurdling step in 110m hurdles and the one step in the middle of 100m men’s hurdle were carried out. The results showed that: Of the ground angle is relatively smaller than Bolt’s ground angle, the significant difference between the two; the moment of landing under the bar, 110m bar in the ground angle of about 10 ° greater than 100m, the distance between the site and the body center of gravity projection is also closer than 100m , But the ground instantaneous trunk anteversion 110m column and 100m the size of the index is almost close.
