Material: we tested students (n=150, from them n=105 - boys and n=45 - girls). дівчата). Measurements were fulfilled after maximal physical load on ergo meter (Kettler, German). The load was 2,7 W/kg. Results: indicators of vegetative blood circulation’s regulation depend on fitness level to maximal physical load. In 1st group students it manifested as sharp asymmetric indicators’ reverse between sympathetic and para sympathetic regulation of blood circulation. Besides, there appear reversibly and irreversibly changed forms of erythrocytes in periphery blood. In 2nd group students maximal physical load causes higher indicators of sympathetic circuit. In 3rd group students, under maximal physical load we did not find asymmetry between sympathetic and para sympathetic blood circulation’s regulation. Conclusions: between changes of vegetative blood circulation’s regulation and students’ fitness to maximal physical load there are multidirectional vectors of organism’s functional state. They manifest as natural changes of forms of periphery blood erythrocytes.</p> ER -
