Influence of blood type serologic markers on development of the function of logical thinking of athletes aged 17-20

Abstract

The articles tackles influence of blood type serological markers on development of psychic function of logical thinking of young athletes aged 17-20. Athletes (male) of teen age (n=132) took part in the research. Based on classification of kinds of sports by A. H. Dembo, they were divided into two groups: group A –speed-and-power kinds of sports (n=69); group B-endurance kinds of sports (n=63). Control group included students aged 17-20 (n=131) who did not do any sport. Analysis of the function of logical thinking was done using “numeric series” method by M.V. Makarenko. Quantitative indices of thinking function evaluation were as follows: the number of correct answers given by participants for a period of time, speed of thinking, general evaluation of thinking. The fact of possible application of blood types in genetic prognosis of thinking development has been detected. It has been revealed that individuals having A(II) and 0(I) blood types have the best associative ties with various features of logical thinking, while those having AB(IV) blood type-the worst one.
