Twenty pre- (N=10) or post- menopausal (N=10) women aged 18- 65 years had one repetition maximum (1RM) determined for the chest and leg press, leg and biceps curl, vertical pull down, triceps and leg extension exercises. On a separate day, participants completed a session of full body resistance exercise (RE) during which subjects performed three sets of 10 repetitions at 75% 1RM for the aforementioned exercises. Blood samples were obtained prior to, immediately, and one hour after exercise. Changes in interleukin-6, -10, and transforming growth factor beta (IL-6, -10, and TGF-β1) were determined via enzyme-linked immunosorbent assays (ELISA). IL-6 significantly increased (P<0.05) over time in both groups. Immediately post exercise levels of IL-10 were significantly lower (P<0.05) in the post-menopausal group. Changes in IL-10 correlated with 17β-estradiol levels (r2=0.45, P<0.001). Menopausal status impaired inflammatory recovery following acute RE. These changes may be attributed to menopause-induced perturbations to the hormonal milieu. Keywords: Cytokines, inflammation, menopause, resistance exercise
