| Popis: | Background: The heart rate variability biofeedback (HRV-BF) method is designed to activate both vagal nerve activity and baroreflex function. The present study aimed to determine the relation between the expression of the spectral power of the dominant peak of the HRV low-frequency (LF) band, its time period, and the degree of blood pressure decrease in 14-15-year-old adolescents who performed short-term HRV-BF training after physical exercise in a cold environment. Methods and Results: Thirty healthy 14–15-year-old males were examined. The study included the baseline stage, physical activity in the cold, post-exercise stage, recovery stage—HRV-BF training (the HRV-BF group, n=20), or resting stage (the control group, n=10). In the control group, systolic blood pressure (SBP) did not change significantly at any examination stage. In the HRV-BF group, the SBP level was significantly lower in the recovery stage than at baseline (110.0 [108.0; 117.0] mmHg and 115.0 [110.0; 128.0] mmHg, respectively, P=0.008), which occurred against the background of an increase in the LF band (2.16 [0.94; 4.62] ×1000, ms2 versus 0.75 [0.47; 0.92]×1000, ms2 in the control group, P |
