新式仰泳出发器对仰泳出发成绩影响的研究

The Impact of New Backstroke Starting Platform on Starting Performance of Backstroke Swimmers

采用现场比赛拍摄、影像解析、数据统计、录像观察等研究方法,对2015年宝鸡冠军赛、2016年佛山冠军赛的男女100米和200米仰泳决赛中使用新旧出发器后的台上时间、出发15米时间、比赛成绩进行比较研究,探讨新式仰泳出发器对仰泳运动员出发成绩的影响程度,为我国运动员使用新式仰泳出发器提供参考。研究结果表明:台上时间和出发15米时间的男女100米、200米仰泳四组数据比较显示,新式仰泳出发器对运动员出发成绩有明显提高。具体数据是:台上时间提高0.03~0.07 s,出发15米时间提高0.10~0.30 s。统计学分析表明,新旧出发器使用后的台上时间具有显著性差异,说明新式仰泳出发器的使用能明显地节约运动员的台上时间,提高仰泳成绩。

By resolving images and game videos, analyzing data statistics, the study compares the starting performance of athletes participating in men and women 100 m and 200 m backstroke competitions in Baoji Championship 2015 and Foshan Championship 2016 with old and new backstroke starting platform on respectively in order to prepare for the Olympic Games in Rio this coming October.The result indicates that: the new backstroke starting platform shortens the starting time 0.03 to 0.07 second and the time needed for the first 15 meters is reduced by 0.1 to 0.3 second.It shows the new backstroke platform make swimmers progress in starting performance.
