游泳运动员指长比的运动等级差异和排序

目的:了解游泳运动员指长比在不同运动等级之间的差异和排序.方法:运用Photoshop8.0图像处理软件和SPSS13.0统计软件对游泳运动员指长进行测量和单因素方差分析.结果:(1)指长比在运动健将和一级运动员之间,除右侧的4D∶5D存在显著性差异外,其它指长比都不存在显著性差异;(2)运动健将和二级运动员,一级运动员和二级运动员之间,指长比确实存在着显著性差异,尤其是2D∶4D,2D∶5D和3D∶4D;(3)各指长比从大到小的排序依次为3D∶5D,4D∶5D,2D∶5D,3D∶4D,2D∶4D,2D∶3D.(4)在2D∶4D上,各运动等级的排序为二级运动员一级运动员运动健将.结论:游泳运动员的指长比,尤其是2D∶4D可能与游泳运动能力有关,可以为游泳运动员科学选材提供理论参考.

Sports Grade Differences and Orderings in the Digit Length Ratios from Swimming Athletes

Objective:To find out the sports grade differences and orderings in the digit length ratios from swimming athletes.Methods:Photoshop8.0 and SPSS13.0 for windows are employed to measure digit lengths of athletes from swimming team and ANOVA is used.Results:(1)Except for 4D:5D of the right hands,there are all digit length ratios significant differences between masters of sports and the first grade sportsmen.(2)For masters of sports and the second grade sportsmen,the first grade sportsmen and the second grade sportsmen,the significant differences do exist in the digit length ratios,especially in 2D∶ 4D、3D∶ 4D and 2D∶ 5D.(3)the ordering of the digit length ratio means in general level was 3D∶5D>4D∶ 5D>2D∶5D>3D∶4D>2D∶4D>2D∶3D.(4)for 2D∶ 4D,the ordering of Sports grade is the second grade sportsmen> the first grade sportsmen> masters of sports.Conclusions:the digit length ratios from swimming athletes,especially 2D∶ 4D are probably related with ability in sport,and they can be employed in athlete selection.
