Abstract
The formation of functional systems in correspondence with the conditions of natural activity is the most important issue of developmental physiology. In this study, data on the assessment of the state of central and cerebral hemodynamics, as well as indices of spectral analysis of the heart rate’s variability (HRV) in adolescents depending on the level of motor activity has been collected and systematized. The possibility of integration of methods of rheoencephallography and cardiorythmography for the assessment of the characteristics of the ontogenetic formation of the cardiovascular system has been studied. Analysis of the formation of indices of hemodynamics during an academic year and the training cycle in swimmers and healthy adolescents who do not enroll in sports classes has been made. Changes in, and correlations between, the parameters of central hemodynamics and cerebral circulation, as well as parameters of HRV, have been detected. Analysis of the changes in the statistical indices of the cardiac rhythm in adolescents during an academic year on the basis of the qualitative and quantitative characteristics of the state of regulatory systems, as well as the determination of the direction of the response to the combination of academic loads and the factor of physical training, permitted a detailed study of changes that take place in some hemodynamic parameters in athletes and students, which is of particular importance for the diagnosis of their functional state.
