In this sense, it seems to be useful to understand the relationship between digit ratio and performance during the pubertal period. Curiously, the period of adolescence involved multiple physiological changes results from the normal development. However, few studies focused on the relationship between athletic performance and digit ratios on adolescents. The majority of the studies have investigated the relationship between athletic performance and digit ratio in adult athletes. Interestingly, digit ratio has also been considered as a predictive marker of athletic performance, and previous research found a negative correlation of 2D:4D on performance in sports (e.g., soccer, basketball, rowing, athletics) and fitness tests (e.g., handgrip strength). This ratio is commonly established as an acceptable predictive indicator of the exposure and sensitivity to prenatal androgen. The length of the second digit (2D) divided by the length of the fourth digit (4D) is called the digit ratio (2D:4D).
