Zusammenfassung
At the present time problem of human physical performance is relevant, especially in sports, because athletes can achieve good results mostly due to the high level of physical performance. Aim. To determine and compare heart rate variability, central hemodynamics and physical performance in runners at a distance of 400 m, obtained in the preparatory and competitive periods of training process. Results. The study of the functional state of the 400 m runners showed strengthening of parasympathetic effects of the autonomic nervous system (ANS) in the competitive period. Also eukinetic circulation type transformation into hypokinetic occurred. Significant increase in physical performance by 8.5% and the IFS by 17.9% was detected. High class runners separate study showed the prevalence of parasympathetic effects of the ANS, hypokinetic circulation type (CT) and lack of athletes with hyperkinetic CT. Significant increase in physical performance at 7.95% and the IFS by 20.2% was detected in them. Athletes with II–III level of qualification in the preparatory period had sighs of the increased parasympathetic ANS similar with eukinetic CT. Nobody had hyperkinetic CT. Conclusions. Correlation analysis between the integrated parameters in the whole group of runners in the competitive period found no significant correlations between the studied parameters.
