Abstract

Abstract. One of the urgent problems of age-related physiology for a long time remains the study of the processes of functioning of body systems in adolescence. The study of the interrelationships of the regulatory mechanisms involved in the formation of an adequate adaptive response during this period is an urgent area of physiological research. Aim. To study the features of the functional capabilities of the nervous system of students of different ages, depending on the prevailing contour of heart rate (HR) regulation. Materials and Methods. The study was conducted among 323 male students of the Cossack cadet corps aged 10 to 17 years. The software complex “Health-express-2” (“Medical Computer Systems”, Russia) was used to register and analyze heart rate variability, as well as to assess the functionality of the nervous system. Results and Discussion. The students of the IV category of HR regulation may indicate an inadequate reaction of the nervous system, depending on the learning conditions. The age dynamics of indicators of the functional capabilities of the nervous system of students has similar changes for categories of rhythm regulation with a pronounced predominance of either the central contour or the autonomous contour. Conclusions. The significance of the influence of various departments of the autonomic nervous system is confirmed by age-related changes in the parameters of the functioning of the nervous system of students with different types of HR regulation. The results obtained allow us to conclude about the complex relationship between the functional capabilities and mechanisms of regulation of the body of students in the learning environment.
