The Autonomic Regulation of Heart Rate of Athletes with Different Levels of Sensor Motor Response

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.
