abstract="BACKGROUND: Assessing different aspects of physical fitness in children whose abilities are undeveloped, and their associations with second-to-fourth digit ratio (2D:4D), may better determine the potential athleticism of an individual. <br><br>AIM: The purpose of the study was to examine relationships between the digit ratios and selected motor and health-related fitness parameters in a large sample of pre-adolescent females. <br><br>SUBJECTS AND METHODS: Participants included 8 to 12 yr old Iranian and Afghan girls. The length of the left and right second and fourth digits were measured by scanning and computer-assisted image analysis. Motor- and health-related fitness tests were evaluated. <br><br>RESULTS: No significant correlations were noted between right 2D:4D ratio and physical fitness components. Left 2D:4D and physical fitness components were not correlated with the exception of handgrip strength (r = -0.193). However, right and left second digit lengths were negatively correlated with predicted VO<sub>2max</sub> (P ≤ 0.01). In addition, right - left 2D:4D was significantly negatively correlated with flexibility, and significantly positively correlated with height and body fat percentage. <br><br>CONCLUSION: In contrast to previous investigations, it seems that left 2D:4D is a predictor of strength, but not aerobic exercise. It is suggested there may be a potential relationship between prenatal androgen exposure and high flexibility, low body fat percent, and the generation of muscular strength in pre-adolescent females.<p /> <p>Language: en</p>",
