摘要：Purpose: to study the types of cardiohemodynamic response of the organism and morpho-biochemical changes of erythrocytes of peripheral blood of volleyball players to physical activity of maximum aerobic capacity. Material and methods In 18 highly qualified volleyball players aged 22.0±0.60 years, cardiohemodynamics (by functional methods), functional changes (by biochemical methods) and the structure of erythrocytes (using scanning electron microscopy) were studied before and after the maximum (3.5 W/kg of body weight) of physical activity. Results. It was found that maximal physical activity causes significant changes in cardiohemodynamics, which result in morphological rearrangement of peripheral blood erythrocytes (increase in erythrocyte deformation index) and closely correlate with biochemical changes (decrease in ATP concentration and increase in magnesium concentration in erythrocytes). Possible mechanisms of realization of features of reaction of an organism of volleyball players to physical activity of the maximum aerobic power depending on type of regulation of blood circulation and morpho-biochemical changes of erythrocytes of peripheral blood are discussed. Conclusions. Physical activity of maximum aerobic power in highly qualified female volleyball players reveals the typological features of the cardiohemodynamic response of the body of volleyball players, which is expressed by conformational changes in peripheral blood erythrocytes and depends on the concentration of individual macroelements in these cells and on the type of cardiohemodynamics.
