Abstract

Different variants of changes in rheoencephalogram (REG) parameters in adolescents during monitoring of heart rate variability (HRV) biofeedback training were determined. Wе surveyed 41 adolescents living in the European North and aged 15–17 years. Each of them performed the first session of HRV biofeedback, recording REG parameters before, during and after the biofeedback session (5 minutes long records). Hereafter we held 8 sessions of HRV biofeedback every day or every other day, and at the last 10th session we recorded HRV and REG parameters before, during and after biofeedback training session. It was established that multiple sessions of HRV biofeedback help reconstruct the tone of large and small vessels of the head, which raises the resistance to cerebral vasodepression in the occipital lobe, and increase the blood filling of the vessels in the frontal lobe while reducing the tone of small vessels and facilitating venous outflow. The most significant stable increase in the total capacity of HRV spectrum, as a controllable parameter at biofeedback training (10 sessions), and reduction in sympathetic activity in adolescents were observed when blood filling of the vessels in the frontal lobe increased.
