We have studied functional capabilities of cardiovascular system in young men of service age in terms of indicators of сardiointervalography. It was stated that people who are 18-21 years old demonstrate increase of values of systolic, diastolic pressure and heart rate after physical activity in comparison with the values obtained in the rest state, while range values of Р, Q, R, S and Т deflections, interval sizes of P-Q, QRS and Q-T, reference and actual reference systole and systolic indicator decrease. Vagosympathetic index of the test persons after the functional test increased as compared with the rest state, which provides evidence of increase in tonus of sympathetic nervous system after physical activit
