The ratio of 2D to 4D is determined at the early stage of development, characterized with gender dimorphism (male’s ratio is sig-nificantly lower than female’s), and considered as a useful index for showing the functions of testosterone prior to birth. Current experimental results hinted that the ratio of 2D to 4D may positively correlative with sports potentials, and that outstanding athletes have a lower ratio of 2D to 4D. The authors suggested using the ratio of 2D to 4D in athlete selection. |
