ObjectivesThe primary aim of this study was to examine relationships between digit ratio (2D:4D) and game‐related statistics in professional and semi‐professional male basketball players. The secondary aim was to quantify differences in mean 2D:4Ds between starting and reserve players.MethodsUsing a cross‐sectional design, 93 male basketball players from the professional Australian National Basketball League and the semi‐professional South Australian Premier League were measured in‐season for height, mass, and 2D:4D, with game‐related statistics collected end‐season. Linear relationships between right and left 2D:4Ds and game‐related statistics were quantified using nonparametric partial correlations, and differences in mean 2D:4Ds between starting and reserve players were quantified using analysis of covariance (ANCOVA). All partial correlations and ANCOVAs were adjusted for playing experience, body size, and competitive standard.Results2D:4D was a weak to moderate negative correlate of points scored and assists‐to‐turnovers ratio, indicating that males with lower 2D:4Ds were generally better offensively as they recorded more points and assists relative to turnovers. The difference in mean 2D:4D between starting and reserve players was negligible.Conclusions2D:4D was favorably correlated with open‐skill sports performance, as evidenced by the better offensive statistics of male basketball players with lower 2D:4Ds. These results probably reflect the organizational benefits of prenatal testosterone and indicate that 2D:4D may be a useful complement to traditional physical, physiological, skill, and behavioral predictors of basketball success.
