无名指和食指的指长比与运动成绩的相关分析

Correlation Analysis on Ring Finger and Index Finger Length Ratio and Their Performance

研究人类第二根手指长度(second finger length,2D)与第四根手指长度(fourth fingerlength,4D)的比率(digit ratio of 2D and 4D,2D:4D)与运动能力遗传存在相关性。结果显示,2D:4D在出生前就已经定型,其与母亲子宫睾酮浓度及成年后睾酮浓度存在着负相关。睾酮浓度会影响大脑右半球和空间视觉能力的发育,从而影响运动能力。

To study the human second fingers length（second finger length,2D） and fourth fingers length（fourth finger length,4D） ratio（digit ratio of 2D and 4D,2D： 4D） and the movement of genetic ability to exist Relevant.Results： 2D： 4D before birth has been established,the concentration of testosterone in the uterus with his mother and adult concentration of testosterone after the existence of a negative correlation.Testosterone concentrations will affect the right brain hemisphere and the capacity of visual space,thus affecting the exercise capacity.
