Abstract

The second digit and fourth digit (2D:4D) finger ratio is known to be an indicator of in utero androgen influence. Here, I review current research concerning 2D:4D ratio, particularly in regards to muscle strength, muscle mass, and athletic ability. Studies on athletes have shown a significant negative correlation between the ratio and athleticism and an inconsistent correlation with muscle mass and muscle strength. I propose a research study on the relationship between the 2D:4D ratio and Crossfit athletes and its relationship to muscle mass and muscle strength.
