Abstract	Cross-spectral power of stroke blood volume oscillations and R-R interval duration at rest, with regulated respiration of 6 cycles per minute, at tilt test and with dosed physical loading with power of 1Vt on 1 kg of body weight were determined on 29 persons of endurance sports, 28 - of power sports and 34 non-sportsmen (in total 91 students aged 18-22). Higher degree of synchronizing stroke blood volume oscillations and R-R interval duration in the range of spontaneous baroreflex sensitivity (0.04 - 0.15 Hz) was found at the athletes if compared with non-sportsmen. The inclusion of homometrical mechanisms of heart work self-regulation was found more marked at the sportsmen of endurance sports with dosed physical loading with increasing amplitude of negative meanings of cross-spectral power in frequency range of 0.01 - 0.03 Hz.
