| （河南理工大学 万方科技学院体育系，河南 郑州 451400） 摘 要：运用Photoshop8.0图像处理软件对大学生篮球运动员和普通大学生的指长进行测量，用SPSS13.0统计软件对所得数据进行描述性统计和两个独立样本间的T检验，探讨大学生篮球运动员和普通大学生的指长比差异以及性别差异。结果：(1)大学生篮球运动员左侧的3D∶5D、4D∶5D和普通大学生左侧的2D∶3D、2D∶4D、2D∶5D存在着显著的性别差异(P<0.05)；(2)不论男女和侧别，大学生篮球运动员和普通大学生的2D∶4D都存在显著性差异(P<0.05)；(3)大学生篮球运动员的2D普遍小于4D。结果表明指长比尤其是2D∶4D与运动能力有关，甚至也可能与篮球运动能力有关，该指标有望为篮球运动员科学选材提供参考。 |

Results: 1) there is a significant gender difference in the 3D:5D and 4D:5D of the left hand of university basketball players and in the 2D:3D 2D:4D and 2D:5D of the left hand of ordinary university students (P<0.05); 2) there is a significant difference in the 2D:4D of the left hand of university basketball players and ordinary university students (P<0.05), no matter boy or girl, left hand or right hand; 3) the 2D of university basketball players is generally smaller than the 4D. The results indicate that digit length ratios, especially 2D:4D, are related to sports abilities, and may even be related to basketball sports abilities; this index is hopeful of providing reference for selecting basketball players scientifically. |
