【摘要】 目的:了解游泳运动员的指长比特征。探讨其指长比尤其是2D:4D和运动能力之间的相关关系。方法:运用PS 8.0图像处理软件测量游泳运动员的指长。SPSS13.0统计软件对指长比进行单因素方差分析和皮尔逊相关分析等。结果:指长比(2D:4D)在运动员与非运动员之间存在着显著性差异(P<0.05)。运动员组间比较结果为,运动健将和一级运动员之间无显著性差异(P>0.05);运动健将和二级运动员,一级运动员和二级运动员之间,2D:4D存在着显著性差异(P<0.05)。2D:4D与运动员运动能力的相关性分析结果是男性比女性显著,右侧比左侧显著。结论:游泳运动员的指长比(2D:4D)与游泳运动能力有关,且与运动等级水平之间呈负相关。对运动员的2D:4D和运动能力之间的相关分析结果可为运动员选材指标的优化研究提供理论依据。更多还原

【Abstract】 Objective: To explore characteristic of digit ratios and the correlation between the sports ability and digital ratio(2D:4D) from swimming athletes.Methods: PS 8.0 was employed to measure digit lengths and SPSS13.0 for windows was used for ANOVA and Pearson correlation analysis.Results: There were significant differences(P<0.05) between athletes and non-athletes in digital ratios,especially in 2D:4D;For 2D:4D,the results among athletics’ grade levels,there were no significant differences between masters of sports and the first grade sportsmen(P<0.05).For masters of sports and the second grade sportsmen,the first grade sportsmen and the second grade sportsmen,the significant differences do exist.The correlation analysis on 2D:4D and athletic ability was significantly more in men than in women and that on the right is more than on the left.Conclusions: the digit ratios from swimming athletes,especially 2D:4D were correlated to sport ability and negatively correlated to the sport level.It is possible to be employed in athlete selection.更多还原
