Abstract

The present study aimed to determine the ratio of 2nd to 4th digit in professional body builders in comparison with controls. 2nd:4th digit ratio is known to be related to ethnicity. However, the magnitude of sex differences in 2nd: 4th is similar across ethnic groups. A total of 37 male body builders training at various gymnasiums who have participated in various competitions at national/international level were scanned and considered as cases. Studies conducted in sports like rugby, rowing and skiing which needs both cardiovascular efficiency and high-power output has shown a significant association between digit ratio and performance. It is concluded that male body builders had a significantly lower 2nd:4th ratio compared to the controls. Therefore, a lower right to left 2nd:4th ratio may be a good predictor of high athletic performance in males.
