For the analysis of sex differences in the morphology of freestyle wrestlers data of 133 women and 88 men were used. The program included 69 absolute and relative indicators of total body size, body proportions, girths, body mass components. The degree (%) and direction of sexual differentiation of each characteristic in women athletes compared to male athletes and their variability (su) were analyzed. The direction of the gender difference was determined by the dominance of the average values (X) of the traits and their variability (su) in one sex group over the other. The coefficient of sexual dimorphism (CSD) by E.G. Martirosov (1976) and S. Bailey (1981) was determined for each individual trait. While the prevalence in men was designated by the sign “+”, the predominance of values characteristic for women had the sign “-”. The results are as follows: 1. According to the calculated CSDs, men in 53 measurements substantially exceed women athletes, mostly in lengths dimensions and diameters. At the same time they are inferior in indicators of subcutaneous fat and the circumferences of the hips and buttocks. 2. The analysis of the CSDs for body mass components shows the large values of indicators of fat mass in women’s bodies and, vice versa, active cell, bone and skeletal muscle mass in men, which is confirmed by the results of bioimpedance examination.
