DEVELOPMENTAL FEATURES OF THE SYSTEM OF REGULATION OF HEART RATE IN A MALE BODY IN STAVROPOL

Abstract

In the mechanisms of regulation of heart rate in men ontogenetic differences. Analysis of the activity of the autonomic nervous system links found fundamentally different regulatory mechanisms - trophotropic in adolescence and ergotrop - in the mature period of ontogenesis. Since the functional regulation of the circulation system is hierarchically organized multi-loop system in which the dominant role of the control loops is determined by the current needs of the body, so far during the study period of ontogenesis and identifed different roles of the central and autonomous circuits, due to both direct and feedback. So in terms of physiological rest in the regulation of heart rate of the male body adulthood signifcant role of the sinus node, the hypothalamic-pituitary and central nervous systems. When the maximal exercise stress test in men of mature age dramatically increased the role of vagal infuences, which revealed a dominant role vasomotor center of the medulla oblongata. In general, a fact revealed a sharp increase in parasympathetic regulation loop when the stress test from a position of physiological interpretation, indicating a decline in the functional activity of regulatory mechanisms and detection of reduced functional reserve of the cardiovascular system.
