It has been suggested that achievement in sports is correlated with a putative measure of prenatal testosterone the 2nd to 4th digit ratio (2D:4D). It has been shown that digit ratio (2D:4D) is negatively associated with prenatal testosterone, and it is also negatively associated with ability in sports. This study examined associations between 2D:4D and performance of both male and female National level Indian swimmers. Age matched non-sports personnel formed the control. Lengths of second and fourth digits were measured after scanning both hands and their ratio calculated. Our results show lower 2D:4D values in males compared to females (P0.05). Among male, but not female, swimmers had significantly (P0.05) lower 2D:4D ratio. Low 2D:4D in male swimmers suggests they are more prenatally programmed via long-lasting extra genital effects of testosterone. 2D:4D ratio could be used to identify young sports personnel who have potential to reach high levels of performance. |
