AIM: Sex differences in exercise responses have implications for understanding sex-specific adaptations to exercise for performance and health. The purpose of this study was to verify the acute effects of a full body resistance exercise protocol on growth hormone (GH), testosterone (TT), cortisol, interleukin (IL)-6 and IL-10 in men and women.
METHODS: Fourteen healthy volunteers (7 men and 7 women taking oral contraceptives) active and recreationally trained in resistance exercise were subjected to a resistance exercise session (3x8-10 RM) composed of 10 exercises with rests periods of 90-120 seconds between sets. GH, TT, cortisol, IL-6 and IL-10 were assessed at pre-, immediate post- (IP) and 30 min postprotocol.
RESULTS: Both men and women had a similar increase in GH (P<0.05) at IP in response to exercise. Significant effects of interaction between sex and time were observed for TT, cortisol and IL-6. In the men, an increase from pre was noted at IP and 30 min for TT, cortisol and IL-6. In the women there was no change in TT, cortisol and IL-6 concentration. There was no change in IL-10.
CONCLUSION: Our findings indicate a difference between men and women taking oral contraceptives in TT, cortisol and IL-6 responsiveness to the same full body resistance exercise protocol.
