Plasma concentrations of glucose (mmol/l) (a), insulin (μIU/ml) (b), and homeostasis model assessment of insulin resistance (HOMA-IR) index (c) in the placebo (Pla, n = 6)-, the 17β-estradiol (E2, n = 6)-treated, the placebo/pair-feeding (Pla/PF, n = 6), and the placebo/exercise (Pla/Ex, n = 6) groups. Data are expressed as means ± SE and were analyzed by one-way ANOVA. This was followed by a post hoc Tukey’s HSD test. *P < 0.05, **P < 0.01, and ***P < 0.001, differences between the Pla and every other group
