Effect of whole-body passive heat stress on heart rate and mean arterial pressure in healthy young and aged subjects

Heart rate (left panel) and mean arterial pressure (right panel) at normothermic baseline and during whole-body passive heat stress sufficient to elevate core temperature by 0.6°C (+0.6°C) and 1.2°C (+1.2°C) in healthy young (n = 11) and aged (n = 10) subjects. Values are mean ± 95% confidence intervals. ^*Significantly different from baseline (P ≤ 0.05). ^†Significantly different between young and aged (P ≤ 0.05). ^‡Significantly different change from baseline between young and aged (P ≤ 0.05).
