Figure 1. Thermoregulatory parameters during the experiment. The change in the average body temperature (A), heat storage rate (B), and heat production (C) of normotensive (n=8) and hypertensive (n=8) subjects at rest, during, and after physical exercise in a hot environment (38°C and 60% relative humidity). Data are reported as means±SD. *P<0.05 hypertensive compared to normotensive (unpaired t-test). The baseline average body temperatures of hypertensive and normotensive subjects were 35.96±0.23°C and 35.83±0.22°C, respectively.
