Objectives

The 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.

Methods

Using 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 …

Digit Ratio (2d:4d) And Muscular Strength In Adolescent Boys, Jordan M. Tomkinson, Grant Tomkinson

Education, Health & Behavior Studies Faculty Publications

Using a cross-sectional design, this study quantified the relationship between the digit ratio (2D:4D) and muscular strength in 57 adolescent boys. 2D:4D was very likely a moderate negative correlate of handgrip strength, even after adjustment for age and body size. This result may reflect the organizational benefits of prenatal testosterone.
