Abstract
AbstractIntroduction: Digit ratio (2D:4D: the relative length of the 2nd and 4th digit)is thought to be a negative correlate of prenatal testosterone. The 2D:4D isrelated to oxygen metabolism, but the precise nature of this relationship isunclear. The purpose of the present study was to consider ass...

AbstractIntroduction: Digit ratio (2D:4D: the relative length of the 2nd and 4th digit)is thought to be a negative correlate of prenatal testosterone. The 2D:4D isrelated to oxygen metabolism, but the precise nature of this relationship isunclear. The purpose of the present study was to consider associations betweendigit ratios (right 2D:4D, left 2D:4D, right–left 2D:4D [Dr-l]) and VO2max andventilatory thresholds (VT1 and VT2).Methods: One hundred and thirty-three Caucasian (n = 133) professionalfootball players competing in Cyprus participated in the study. Players underwent anthropometric measurements, and digit lengths were measured fromhand scans. They also completed an incremental cardiopulmonary test toexhaustion on a treadmill.Results: There were negative correlations between digit ratios and VO2max(right 2D:4D, r = .65; left 2D:4D r = .37, both p < .0001; Dr-l r = .30,p = .0005). There were no relationships between digit ratios and VT1. ForVT2, there were negative relationships with digit ratios (right 2D:4D, r = .43,p < .0001; left 2D:4D, r = .21 and Dr-l, r = .21, both p = .02). Digit ratiosare negatively related to VO2max with large (right 2D:4D) and medium (left2D:4D, Dr-l) effect sizes. For VT2, there were also negative correlations, whichwere medium (right 2D:4D) and small (left 2D:4D, Dr-l).Conclusion: Our findings may help clarify the relationships between digitratios and high-intensity actions for extended periods, which are dependent onefficient oxygen metabolism. |
