Contest results and the condition of vegetative regulation of young gymnasts

The dynamics of heart rate variability (HRV) and the indices of central hemodynamics (ICH) of young woman gymnasts in two contest seasons have been analyzed. The research was conducted using orthostatic tests. Individual and typological peculiarities of gymnasts’ vegetative regulation were taken into consideration. Analyzing the research results of gymnasts’ HRV with different types of vegetative regulation, different body response to a training load and orthostatic tests was noticed. It’s shown that having excessive and paradoxical response of regulation systems to the orthostatic test the changes occurred in the indices of central hemodynamics. It’s proved that the excessive training load under the conditions of high stress of regulatory systems could lead to the myocardial contractility, expressed in the decrease of stroke volume and minute blood volume after training. In our paper we’ve come to the conclusion that contest results depend on the condition of systems regulating the heart rhythm of gymnasts and the condition of these systems can be estimated in the individual approach to the HRV analysis.
