The issues of determining innate abilities and predispositions, identifying the optimal work schedule during the day and preventing professional burnout are becoming increasingly relevant for both researchers and practitioners. This is due to the awareness of the importance of studying individual characteristics for the correct choice of profession, sports specialization and building an effective routine. However, traditional methods of questioning and self-assessment often produce inaccurate or incomplete results. Modern scientifically based and patented hardware diagnostic methods, such as gas discharge visualization (GDV), galvanic skin reaction (GSR) and motor express diagnostic methods for the properties of the nervous system, allow us to obtain an objective and comprehensive picture of human abilities and capabilities for personal development and self-realization. The use of psychophysiological testing methods and the concept of typological complexes to determine the innate characteristics of a person, based on the theory proposed by Nobel Prize winner I.P.Pavlov, which was developed in the works of Russian scientists of the scientific school of differential psychophysiology, is of particular importance in sports training.
