Abstract

Digit ratio (2D:4D; a putative correlate of prenatal testosterone) has been reported to be negatively associated with aggression in non-sporting and sporting populations. 2D:4D has previously been suggested to be a potential biomarker for successful competitive performance within boxing football, rugby, athletics, skiing, and gym-based exercises. However, to date no study has attempted to investigate prenatal testosterone levels as a predictor of sporting choice. This study included a sample of both athletes and non-sports people in order to examine associations between prenatal testosterone (2D:4D), aggression, choice of sport (contact vs. non-contact), attainment level, and longevity. 200 male participants completed a self-report measure for aggression followed by providing a hand scan, which was later used to measure 2D:4D using Vernier Calipers. Results showed individuals involved in sport exhibited significantly greater levels of both prenatal testosterone (lower 2D:4D) and physical aggression compared with their non-sporting counterparts. Athletes from contact sports (rugby, football and boxing) were found to have significantly lower 2D:4D and significantly higher levels of physical aggression compared to athletes from non-contact sports (basketball, golf, weight-training, badminton). Additional findings, regarding longevity, showed those exposed to higher levels of prenatal testosterone (low 2D:4D) had been involved in sport for more years compared to those with high 2D:4D, adjusting for age. Findings may contribute to more reliable predictions of sporting selection and longevity. Future studies should look to replicate findings across a greater variety of sports using professional/elite populations.
