Determination of morphological masculinization markers of highly qualified female athletes

The study of morphological body masculinization exertion of highly qualified athletes of sports specializations with different types of motor activity (artistic gymnastics, martial arts, athletics, sports games) is conducted. The study involved 66 highly qualified athletes (Masters of sports and Candidates for Master of sports) aged 19-21 and 16 students of the same age who are not involved in sports (control group). In order to determine the degree of sexual dimorphism inversion in female athletes, the indices of sexual dimorphism (masculinity index, D. Tanner index, and finger index «2D:4D») were calculated based on data from an anthropometric study. It is concluded that two indicators can be used as universal morphological criteria for sports selection in girls - the Tanner index and the index of finger proportions "2D:4D".
