Abstract
With increasing sports qualification of Athletes, the speed of visual response is increased in order of the magnitude. In the competition conditions, the manifestation of neural and psychomotor abilities of athletes depends on the functional state of the organisms. The main physiological adaptation to sport activity is the requirements to psycho physiological functions and to the heart rate regulation system. The aim was to study the features of autonomic regulation of heart rate of athletes with different levels of sensory-motor response. 24 elite athletes (Greco-Roman Wrestlers) were examined. The age of the athletes was 20-25. The peculiarities of sensory-motor response were studied on individual-typological characteristics of nervous system. The autonomic regulation of the heart rhythm was performed using cardio monitor «Polar-S800» with the registration of the spectral characteristics of heart rate. The results show that the growth rate of sensory-motor response of elite athletes is accompanied by psychomotor stress, which leads to the stability of visual reaction. The rate of sensory-motor response has communication with the tension of regulation of heart rate at the expense of parasympathetic tone, which is consistent with a decrease in the duration and frequency of the oscillations cardio intervals of athletes with high speed of sensory-motor response. The presence of a stochastic organization of the functional system of regulation of heart rate in athletes with high speed sensory-motor response reflects the ability of an athlete to adapt to the intense muscular activity.
Highlights
One of the main properties of psycho physiological functions of athletes is the perception of sensory information [1]
Several factors which characterize the efficiency of sporting activity: afferent component of information processing, central component and efferent component of information processing which are influenced to the psycho physiological response of athletes [2,3]
With the increasing of qualification of athletes the speed of visual response is increased in order of the magnitude [4,5]
Summary
One of the main properties of psycho physiological functions of athletes is the perception of sensory information [1]. Several factors which characterize the efficiency of sporting activity: afferent component of information processing (reception and perception of information), central component (information processing) and efferent component of information processing which are influenced to the psycho physiological response of athletes [2,3]. The system of vegetative regulation of heart rate is one (один из) или (the one -как было написано-единственный из) of the key components of functional states of human in tension muscular activity. The results of investigation of relation between psycho physiological reaction and vegetative regulation of heart rate during extremely activity are presented in the literature [8,9,10]
