Diurnal patterns of cortisol and dehydroepiandrosterone (DHEA) secretion, the two main peripheral secretory products of the hypothalamic-pituitary-adrenal neuroendocrine stress axis, have been well characterised in rest conditions but not in relation to physical exercise. The purpose of this investigation was therefore to determine the effects of an intense 90-minute aerobic exercise on the waking diurnal cortisol and DHEA cycles on 3 separate days [without exercise, with morning exercise (10:00-11:30 hours) and with afternoon exercise (14:00-15:30 hours)] in 9 recreationally trained soccer players. Saliva samples were collected at awakening, 30 min after awakening and then every 2 hours from 08:00 to 22:00 hours. A burst of secretory activity was found for cortisol (p<0.01) but not for DHEA after awakening. Overall, diurnal decline for both adrenal steroids was observed on resting and exercise days under all conditions. There was however a significant increase in salivary cortisol concentrations on the morning-exercise and afternoon-exercise days at, respectively, 12:00 hours (p<0.05) and 16:00 hours (p<0.01), versus the other trials. This acute response to exercise was not evident for DHEA. The results of this investigation indicate that 90 minutes of intense aerobic exercise does not affect the circadian pattern of salivary adrenal steroids in recreationally trained athletes over a 16-hr waking period, despite a transitory increase in post-exercise cortisol concentration. Further studies are necessary to determine whether these results are applicable to elite athletes or patients with cortisol or DHEA deficiency.
