针对第七届全运会女子１００ｍ栏比赛情况，对女子１００ｍ跨栏的全程速度曲线、分段速度、平均步长和步频、跨栏步长分配及栏间节奏等进行量化研究．结果表明，我国运动员与奥运会１００ｍ栏选手全程速度变化有着共同的规律和水平差异．步长与步频的合理分配不仅是决定速度的主要原因，也是构成跨栏跑节奏的重要因素．提高栏间最高速度及保持速度的能力是获得优异成绩的关键． Aiming at the 100m hurdles competition in the 7th National Games, the full speed curve, section speed, average step and step frequency, hurdle step allocation and hurdle rhythm of women 100m hurdles were quantitatively studied. The results show that the athletes in our country have common rules and level differences with the 100m hurdlers in the Olympic Games. The reasonable allocation of steps and steps is not only the main reason for determining the speed, but also constitutes an important factor in the hurdling pace. The ability to maximize top speed and maintain speed is the key to good results.
