Figure 1.
Whole-body sweat rate during repeated bouts of physical activity.
Whole-body sweat rates at the end of each exercise bout performed in a direct calorimeter regulated to 35°C and 20% relative humidity. * Significant difference between males 56–70 and 20–31 years. § Significant difference between males 50–55 and 20–31 years. ‡ Significant difference between males 45–49 and 20–31 years. Values are presented as mean ± SE. Significance level accepted at P≤0.05.
Figure 2.
Cumulative change in body heat storage over two hours of physical activity/rest in the heat.
Total amount of heat stored in the body after four 15-min bouts of cycling at an external workload of ∼80 W separated by 15-min rest periods at an ambient air temperature of 35°C and 20% relative humidity. * Significantly different from age group 20–31 years. Values are presented as mean ± SE. Significance level accepted at P≤0.05.
