Introductoin. Sexual dimorphism is the difference in form between male and female individuals of the same species in the world of plants, animals and humans. This difference in form manifests itself in various spheres of life. The phenomenon of sexual dimorphism is a factor particularly important in physical education and sports. Functional differences between men and women provide different opportunities for athletic performance or may be the reason why it is virtually impossible for women to practise some sports. Access for women to almost each sport becomes a fact. Many countries, which are the leaders in international sports competition including Olympic Games, owe their position mainly to women's achievements. In Poland participation in sports among women is too limited. It seems impossible to maintain or improve the position of Polish sports in international rankings without their participation. The purpose of this study was to determine dimorphic differences in male and female judoists, regarding body composition as well as aerobic and anaerobic physiological factors. Material and methods. The research covered male and female judoists of KS AZS Sports Club at the Academy of Physical Education in Gdańsk. The research was conducted after the end of a preparatory period of an annual training cycle. The 30-second Wingate test version was used to assess the anaerobic power. The tests were conducted using a "Monark" cycle ergometer. The aerobic power test was conducted on a Jaeger cycle ergometer with the load being increased until refusal to continue effort. The effort started from the 1.5 W/kg body mass load. After 5 minutes of work the load was increased by 25 Watts every minute. Results and Conclusions. The observed significant statistical differences in body composition between male and female judoists proved that the training loads applied within the same group revealed the traits of sexual dimorphism. Manifestations of sexual dimorphism were also found in physiological indices.
