Figure 3 Changes in serum cortisol concentrations after exercise. Values represent means (SEM). As serum cortisol concentrations remain virtually unchanged at rest, the baseline (pre‐exercise) values were compared with serum cortisol concentrations observed during the 2‐h period after exercise. *Significantly greater than pre‐exercise values (p = 0.014). †Trend to be greater than pre‐exercise values (p = 0.10 (15 min); p = 0.06 (20 min); p = 0.07 (25 min)). ‡Significantly lower than pre‐exercise values (p = 0.03 (85 min); p = 0.003 (100 min); p = 0.02 (130 min)).
