Genetic influences and endurance exercise have been shown to alter circulating concentrations of dehydroepiandrosterone (DHEA) and its sulfated conjugate, DHEAS. We hypothesized that acute resistance exercise (RE) and training (RET) would increase DHEA steroids, and the magnitude of the increase would be influenced by a steroid sulfatase (STS) gene variation. Fasting blood samples were collected before and after the first (S1) and last (S30) session of a 10-wk RET program in 62 men and 58 women [age: 21.0 yr (2.4)]. Acute RE increased both DHEA [+2.8 (0.4), S1; +1.6 ng/ml (0.4), S30; P < 0.001] and DHEAS [+154 (24), S1; +166 ng/ml (15), S30; P < 0.001] and decreased DHEAS:DHEA [-27 (8), S1; -15 (7), S30; P < 0.01]. RET reduced resting DHEAS (-122 ng/ml, P < 0.01) and decreased DHEA response to RE (-50%, P < 0.05). Subjects with an STS "G" allele (n = 36) had greater acute changes in DHEA [+4.4 (0.7) vs. +2.0 ng/ml (0.5), S1; +3.2 (0.6) vs. +1.0 ng/ml (0.4), S30; P < 0.01] and DHEAS:DHEA [-37 (11) vs. 5 (7), S30, P < 0.05] than those subjects with only an "A" allele (n = 84). The observed increase in DHEA and DHEAS and decrease in DHEAS:DHEA suggest RE-induced STS activation which is influenced by the STS polymorphism.
