Effects of the four experimental conditions (solid line)—control, moderate exercise (MOD), vigorous exercise (VIG), and psychological stress—on cortisol concentrations. (a) Temporal profile of cortisol increases. Data are the mean ± SE of the absolute values (ng/mL) of salivary cortisol. (b) Increases of cortisol at 0 min, 15 min, and 35 min after the end of the experimental conditions. Data are the mean ± SE of the absolute values (ng/mL) at these time points after the subtraction of the second baseline sample (−15 min). Number of subjects in parenthesis. * p < 0.05 compared to control after paired t test.
