Figures & data

Figure 1.  Diurnal pattern of salivary cortisol concentration on the rest day (rest) and the two exercise days [(morning-exercise day (ex AM: 10:00–11:30 h); afternoon-exercise day (ex PM: 14:00–15:30 h)] (mean ± SEM) in nine recreationally trained soccer players (two-way ANOVA). Concentrations were higher in the early morning than in the evening (p < 0.01, ANOVA) and highest 30 min after awakening (p < 0.01, Tukey), irrespective of exercise. *p < 0.05, ex AM versus rest and ex PM; **p < 0.01, ex PM versus rest and ex AM.

Concentrations were higher in the early morning than in the evening (p < 0.01, ANOVA) and highest 30 min after awakening (p < 0.01, Tukey), irrespective of exercise. *p < 0.05, ex AM versus rest and ex PM; **p < 0.01, ex PM versus rest and ex AM.

Figure 2.  Diurnal pattern of salivary DHEA on the rest day (rest) and the two exercise days [(morning-exercise day (ex AM: 10:00–1:130 h); afternoon-exercise day (ex PM: 14:00–15:30 h)] (mean ± SEM) in nine recreationally trained soccer players (two-way ANOVA). No significant group differences. Concentrations were higher in the early morning than in the evening (p < 0.01, ANOVA), irrespective of exercise.
