Abstract
Background and Determination of sensorimotor function is an important area of psychophysiological
Aim of Study: 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.

Keywords: sensorimotor regulating, overstrain of the cardiovascular system, sportsmen, physical
