The aim of the present study was to investigate resting measures of dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulphate (DHEA-S) and cortisol, and the response and recovery of these hormones to acute exercise, in male and female older adults of different exercise training status. Participants were 49 community dwelling older adults (23 females) aged between 60 - 77 years who were either: sedentary (n = 14), moderately active (n= 14), or endurance trained (n = 21). Participants undertook an acute bout of exercise in the form of an incremental submaximal treadmill test. The exercise lasted on average 23min 49sec (SD = 2min 8sec) and participants reached 76.5% (SD = 5.44) of predicted maximal HR. Blood samples were collected prior to exercise, immediately, and 1h post exercise. DHEA levels significantly increased immediately post exercise, however, DHEA-S levels only significantly increased in females. Cortisol significantly decreased immediately post exercise, and 1 h post exercise compared to pre. There were no significant differences in resting hormone levels, nor hormonal responses to exercise between training status groups. The findings suggest that exercise can stimulate DHEA production in older adults, and that hormonal responses to exercise differ between male and female older adults.
