REACTIVITY OF HEART RATE AUTONOMOUS NERVOUS REGULATION DURING THE COURSE OF HEART RATE VARIABILITY BIOFEEDBACK IN TEACHERS
The aim of the study was to examine the performance of the autonomic nervous regulation of heart rate before and after a course of heart rate variability (HRV) biofeedback sessions in order to increase the total power spectrum of heart rate variability in teachers with signs of sympathetic and professional experience of more than 20 years compared with a group of people without such training. A total of 25 teachers (women) Arkhangelsk Pedagogical College in the process of working time - 15 teachers who received 10 sessions of HRV biofeedback and 10 teachers who have not passed such a course. In teachers who received 10 sessions of HRV biofeedback, the final session revealed an increase of vagal influences on the heart rate and decrease in sympathetic activity, which becomes more pronounced after 4-5 biofeedback session. In persons who not have undergone biofeedback sessions course, the degree of reactivity of the autonomic nervous structures remains at an average of the first session. By the 10th session of HRV biofeedback baseline value of the total HRV power spectrum in teachers received training, it is 1.5 times higher than in those of the control group.
