A: γ1-AMPK activity immediately postexercise. B: γ3-AMPK activity immediately postexercise. C: γ1-AMPK activity 3 h postexercise. D: γ3-AMPK activity 3 h postexercise. For γ1-AMPK activity assays n = 5/group. For γ3-AMPK activity assays n = 8/group. Data were analyzed by one-way ANOVA. *P < 0.01, significantly greater than both other treatment groups. Values are expressed as means ± SEM. HFD, high-fat diet; LFD, low-fat diet; SED, sedentary; IPEX, immediately postexercise; 3hPEX, 3 h postexercise.
