Special Aspects of Heart rate Variability in Track and Field Athletes and Players

The article was considered the features of autonomic regulation of heart rate in athletes. Modern level of sporting achievements puts forward the necessary conditions for study and evaluation of functional states and adaptive capacity of all body systems in interconnection, taking into account the autonomic regulation of the heart, the problem is actual enough. In the study were surveyed sportsmen playing sports and track and field athletes, using a method of HRV. It was studied the basic of time, spectral and HRV parameters (in R. Baevskyi) and established the predominant type of of vegetative regulation of cardiac activity. Athletes of team sport were characterized by a decrease in indexes of time than heart rate. he analysis of of spectral indexes has shown increasing values in track and field athletes. It was established predominant type of sympathetic autonomic regulation of the heart in sportsmen playing sports, and the track and field athletes found predominant type of parasympathetic autonomic regulation. Obtained results are confirm lowering mechanisms of self-regulation and activation energy centers metabolic for sportsmen playing sports. In track and field athletes were established a higher level of physical fitness and note the decrease in activity of the central control loop.
