Sensorimotor Criteria for the Formation of the Autonomic Overstrain of the Athletes’ Cardiovascular System

Background and Aim of Study: Determination of sensorimotor function is an important area of psychophysiological features study of the athletes’ body, which are essential for the analysis of cognitive processes, assessment of the central nervous system functional state, sensory sensitivity, development of motor skills, psychophysiological and neurophysiological parameters of brain. The aim of the study: to define the changes of indexes of the central regulation of sensorimotor function of highly skilled sportsmen at forming of the cardiovascular system overstrain. Material and Methods: On results research of the cardiovascular system with the use of spiroarteriocardiorhythmography before, after load and a next morning in 19 sportsmen of men, which the overstrains of the cardiovascular system was forming, were determine: at 10 – on a sympathetic type, at 9 – on a parasympathetic type. In parallel was determination of index of switching of central settings (SCS) which received from data of research of the sensorimotor system with the use of device the “Computer motion meter”. Results: Right after intensive physical activity the meaningful acceleration of SCSl (p<0.05) and meaningful deceleration of SCSr (p<0.05) is marked at an overstrain on a sympathetic type, and also meaningful deceleration of SCSl (p<0.05) and meaningful acceleration of SCSr (p<0.01) at an overstrain on a parasympathetic type. In the period of recovery deceleration of SCSl and SCSr (p<0.05) at a sympathetic overstrain, and also stability of index of SCSl by comparison to afterload and meaningful dynamics of SCSr (p<0.05) is marked at a parasympathetic overstrain. Conclusions: At a sympathetic and parasympathetic overstrain the characteristic asymmetric changes of indexes of SCS that can testify to the primary flow of ergotrophic and trophotrophic processes in the organism of sportsmen are marked.
