摘要
本文对我国42名优秀男子短距离自由泳运动员进行了形态、素质测试和比赛途中游技术动作录相分析,对中、外运动员的情况进行了比较。在聚类分析的基础上进行逐步回归分析,筛选出对划频、划幅有显著作用的形态、素质因素。结果表明,划频、划幅在很大程度上受臂长、纵跳、划水拉力等形态、素质因素的影响。从差距和发展潜力看,当前我国男子50米和100米自由泳应注意提高划频,200米自由泳应注重提高划幅,可通过相应素质的发展有针对性地改造划频、划幅。
Anthropometric measurements of 42 male freestyle sprinters of China were taken, their physical qualitieswere tested, and their performances in the pool were recorded by video. By means of a progressive regressionprogramme, factors that had the most significant bearings on the stroke rate(R)and stroke length(L) were sort-edout.These were found to be the arm length,vertical jump, stroke strength and so on. To lessen the gap betweenChinese and foreign swimmers and to tap the latent potentialities of Chinese performers, it is suggested thatemphasis should be laid on increasing the stroke rate in 50m and 100m freestyle swims and on enlarging thestroke length in the 200m event. To these ends, physical qualities of the swimmers should be further improved.
