Radial Pressure Pulse and Heart Rate Variability in Heat- and Cold-Stressed Humans
Figure 5
Effects of thermal stresses on the HRV. (a) The integrations of HF and LF decreased after heat stress and increased after cold stress, and (b) LF/HF ratio increased after heat stress and decreased after cold stress, and there were no changes in HF% after heat stress and increases after cold stress, *compared with the control.
