仰泳双手双脚重叠并拢滑行技术的运动学分析

The Kinematic Research on Sliding with Hands and Feet Overlapping together in Backstroke Swimming

双手双脚重叠并拢滑行技术是一种逐渐发展普及的游泳技术,也是在仰泳项目中国际优秀运动员所使用的技术。通过对6名江苏省优秀仰泳运动员进行双手双脚重叠并拢滑行技术训练教学,并对滑行、出发、转身后滑行成绩和技术进行比较分析,证实该技术的效果,探寻仰泳项目中该技术形成的最佳途径与方法。研究主要使用影像解析分析方法对主要运动学指标进行分析,结果表明使用该技术能显著提高蹬边滑行、出发滑行成绩,也能提高转身滑行成绩,且该技术的运用不影响整体技术发挥,表明双手双脚重叠并拢滑行技术是一种科学有效的仰泳滑行技术。有必要在训练比赛中推广该技术,同时在日常训练比赛中加强系统训练,并注意结合运动员个人特点进行针对性教学,尤其是转身中的技术运用。

Sliding with hands and feet overlapping together is a potential technique in the backstroke swimming. It is popularly used for international elite athletes at present. This article sought to prove the effect of this technique through 14 weeks trainingwith 6 advanced athletes of Jiangsu Swimming Team. And this article also compared the performance of old technique, new technique and new technique after systematical training in sliding, starting sliding and turning sliding. The study mainly used video results showthat this technique can significantly improve the performance of sliding and starting sliding, also can improve the turning sliding performance, while does not afect tiie ovvrall play. The present study indicated that to-gether overlapping hands and feet is a kind of scientific and eective backstroke technique. It is necessary to pro-mote this technique in training and competition. The con-clusion suggests that the systematical training should strengthen in the daily training, and pay attention to the combination of individual characteristics of the athletes through targeted teaching,especially in the turning.
