RESEARCH OF PECULIARITIES OF DEVELOPMENT OF TIME PERCEPTION FUNCTION IN 13-15 YEAR-OLD ATHLETES WITH DIFFERENT BLOOD GROUPS.

The aim of the work is to investigate the influence of serological markers of blood groups on the development of the time perception function in adolescent athletes taking into account sexual dimorphism. The study involved girls (n=178) and boys (n=139) from a specialized sports institution, who according to the classification of sports by A.G. Dembo were divided into two groups: group A - speed and power sports, group B - endurance sports. The control group consisted of pupils [girls (n=117), boys (n=106)] aged 13-15 years and students [girls (n=115), boys (n=150)] aged 17-20 years, who did not play sports. The research of the time perception function was carried out according to the method of V.L. Maryshuk et al., the prototype of which is the method of D.Zakay, R.A. Block. The fact of possible use of blood groups in genetic prediction of development of time perception was established. Individuals of male and female sex with blood group B (III) have been found to have the best associative relation with the properties of this function, while the worst relation remains unclear. The properties of time perception are more expressively manifested in students in late adolescence than in pupils in early adolescence. It was found that sexual dimorphism does not make significant adjustments in the specifics of changes in the time perception function, but genetic markers of blood groups are more informative in predicting the development of the above-mentioned mental quality in boys with B (III) blood group than in girls with the same blood group.
