The constant progress of sports results is closely linked with the improvement of training methods and the development of knowledge about the physical reserve capabilities of man. The use of increasing the volume and intensity of training to improve technical and physical training is now exhausting. Therefore, the search for new ways to improve the effectiveness of training athletes to achieve high sports results. Material and research methods. The study used such methods by which it was possible to achieve this goal, namely the analysis and systematization of psychological, pedagogical and scientific literature, information resources of the Internet that allowed for modern analysis, to determine the level of development of functional asymmetry in working with athletes. analysis of normative documents in the field of physical culture and sports. Results. Individual features of a person are largely expressed by functional asymmetry, because these features of a person are manifested depending on which hemisphere plays a leading role in these processes. Thus, the dominance of one or another hemisphere forms not only the features of thinking, temperament type, features of memory, attention, but also determines the leading arm, leg, ear, eye. Individual features are formed in the individual profile of human asymmetry, and it is directly related to the choice of behavior in extreme conditions and adaptation, perception and processing of information, emotional and autonomic response, verbal and nonverbal intelligence. Сonclusions. The necessity and expediency of creating a new applied direction of sports science, which will include its own subject of study, general and specific concepts, methodological bases, conditions and means of pedagogical support of physical education and sports training taking into account functional asymmetries of the brain, which should be aimed at interaction basic biological, psychophysiological, socio-psychological characteristics of athletes and, on this basis - on differentiated training, taking into account the individual characteristics of functional specialization and interaction of brain areas
