Functional asymmetry of volleyball players as a phenomenon of psychomotor activity

functional asymmetry of the brain of volleyball players is a set of signs of inequality of motor psychomotor acts in the halves of the body, as well as in the upper and lower extremities. The lateral phenotype of a person is a factor that determines the success of adaptation to loads that implement motor programs. The technique of performing game techniques in volleyball depends on functional features and can have right-sided or left-sided loads. To study the pattern of changes in functional asymmetry in young men who regularly play volleyball in relation to their natural abilities for movement. Assessment and change of functional asymmetry of young volleyball players was organized by testing forces with a wrist dynamometer in the phase of maximum tension and the phase of the ability to distribute force, accurately falling within a given range. The third test involved hitting a target with tennis balls. The overall result of testing with the right and left hands was calculated as a percentage. At the end of the assessment of functional asymmetry, the lateralization coefficient was calculated, which had a homogeneous result in the control and experimental groups at the beginning of the experiment. At the end of the experiment, in a group of young men who regularly played volleyball, a change in functional asymmetry was revealed, which indicates the influence of the chosen specialization on the formation of unilateral psychomotor development. The functional asymmetry of the brain in young men playing volleyball increases as a result of their sports activity, as evidenced by a change in the lateralization coefficient. Assessment methods can serve as a marker in sports selection for qualification in a playing role.
