We conducted a study on the intensity of educational activities and determined the typology of the physiological reactions of the body of each of students with different levels of efficiency. The intensity of the educational process of students is given by the method of V.R. Kuchma, E.A. Tkachuk, N.V. Efimova, I.V. Mylnikova (2015) with a scoring of intellectual, sensory, emotional loads, mode and monotony of educational work. A survey of 295 students divided into three groups of 60 people was conducted at a time. There were students with a normal level of efficiency, with reduced efficiency and with significantly reduced efficiency. The functional state of the central nervous system, the autonomic nervous system was determined on the hardware-software complexes based on the methods of, respectively, variational chronoreflexometry and pulsometry. The leading factors of students’ educational activities were high intellectual, visual loads and irregular schedule of academic work, which were assigned to class 3 of 2nd degree on unsocial conditions. In conditions of intense learning activities, only every third student had a normal level of efficiency. We have established the fact of a decrease in the functional state of the central nervous system, stability of the nervous response, adaptive capacity due to the intra-system mismatch of the autonomic nervous system departments and its regulation levels in students with reduced and significantly reduced efficiency as compared with students with normal efficiency. Those can become a scientific basis for the formation of targeted preventive measures to improve the level of efficiency through the normalization of these physiological processes.

Introduction: In solving the problem of preserving and strengthening health of gifted schoolchildren representing the country’s main intellectual potential, the main component is the observance of hygienic requirements for conditions and organization of learning activities in educational establishments for gifted children and adolescents. The purpose of the study was to conduct a prenosological assessment of the health status of gifted adolescents influenced by various educational process factors. Materials and methods: Using hardware and software systems, we assessed the level of physical development, functional status of the central nervous, respiratory, and cardiovascular systems in 300 gifted adolescents in grades 9–11 (15–17 years of age). Results: We established that under the conditions of a boarding school (lyceum), gifted schoolchildren were exposed to such health risk factors as increased study loads, their irrational distribution during the school day and week, and a high level of tension in the educational process (class 3.1). It was proved that the educational process factors affected the functioning of the basic systems of the body of gifted schoolchildren. High study loads of a pronounced degree of tension ensured an improvement of the functional status of the central nervous system of gifted school-age adolescents by stabilizing the nervous reaction, increasing the functional level of the nervous system and the ability of the central nervous system to form the body’s adaptive system when adapting to the factors of the educational process in the in the dynamics of learning. Maintaining a high level of functioning of the central nervous system in gifted school-age adolescents was ensured by the multiparameter interaction of the main body systems, which was characterized by an increase in the functional parameters of the respiratory system, a change in vegetative regulation, and a decrease in the level of biological adaptation. Conclusions: Our findings determine the need for systematic screening of gifted children in educational institutions to identify the level of their prenosological health in order to maintain and increase the adaptive potential of gifted adolescents.
