Individual asymmetry profile as a factor of motor stereotype of qualified athletes

Interhemispheric asymmetry profile correlates with success in various types of sports activity. Team playing sports have special requirements for the manifestation of symmetries - asymmetries. However, the studies of functional symmetry - asymmetry in team situational sports are not enough, although their relevance is in no doubt. The research aim are comparative characteristics of the distribution features of the individual asymmetry profile (IAP), its sensory and motor components of qualified athletes, specializing in basketball and football. The research methods - IAP was determined with the help of 44 tests to identify preferences in motor skills of the upper and lower limbs, vision and hearing. Lateral preferences for players have been systematized depending on the chosen sport. For the vast majority of athletes, regardless of specialization, the rightness of sensorimotor functions has been shown. The most common options in the ranking were «rrrL», «rrrr» и «rrLr». Integral quantitative assessment of the severity of asymmetry with the calculation of the coefficient of integral asymmetry (CIA) revealed significant functional dominance of the left (analytical) hemisphere in both groups of athletes. A high concentration of «absolute» left-handers is shown for basketball players, among football players, ambidexterity of the lower limbs is common. Features of the profile of functional sensorimotor asymmetry, on the one hand, testify to the consolidation of the lateral preferences of athletes in accordance with the nature of the loads in the chosen sport, on the other hand, undoubtedly, are the result of many years of systematic sports selection of players. The results obtained can serve as an additional reserve for the optimization of scientifically grounded sports selection, individualization of the training process, adequate to the specifics of sports technique and the perception of an athlete, improving model standards in the chosen sport.
