不同水平女子运动员50m自由泳途中游速度和划频、划幅变化的研究

On Change of Speed,Stroke Rate and Stroke Length During 50 m Freestyle Swimming in Different Standard Women

采用游泳比赛现场测试方法,对女子运动员50 m自由泳途中游每10 m游泳速度和划频、划幅技术进行了测试。结果显示:50 m自由泳速度的下降与运动水平无关,速度的下降主要是由划频的下降造成的。因此,要求高水平短距离游泳运动员不仅应具备高水平的速度能力同时应具有保持高速度运动的能力。

Using the means of testing in the scene,the author measures stroke rate and stroke length during sprint freestyle in women. The result shows that the descend of velocity is not independent of athletics level,but the descend of stroke rate is main cause. High levels athlete not only have favorable capability of velocity but also the capability of keeping high speed.
