A: glycogen in epitrochlearis muscles at 3 h postexercise (3hPEX). HFD, high-fat diet; LFD, low-fat diet; SED, sedentary. *LFD-3hPEX < LFD-SED (P < 0.001) and HFD-3hPEX (P < 0.05); †HFD-3hPEX < HFD-SED (P < 0.001). B: γ3-AMP-activated protein kinase (AMPK) activity in epitrochlearis muscles at 3hPEX. Data were analyzed by 2-way analysis of variance. Tukey post hoc analysis was performed to identify significant differences. Comparisons between SED and 3hPEX rats within each diet group that were made with Student’s t test revealed significantly greater γ3-AMPK activity in muscles from LFD-3hPEX vs. LFD-SED rats (*P< 0.05), but no significant difference was detected between HFD-3hPEX and HFD-SED rats. Values are means ± SD; n = 6 or 7 rats per treatment group.
