Immediately after exercise + electrical stimulation (0 h PEX + PES). Following 2 h of exercise bout (4 × 30 min) or sedentary, isolated rat epitrochlearis muscles were frozen immediately or were incubated in serum or serum-free buffer before and during in vitro electrical stimulation or resting control and were frozen immediately after. A: experimental design. B: muscle glycogen concentration: data were analyzed with Kruskal-Wallis nonparametric 1-way ANOVA on ranks and the Dunn's post hoc test. *P < 0.05 (significantly different from 0 h REST). C: p¹⁷²ThrAMPK; data were analyzed with 1-way ANOVA and the Student-Newman-Keuls post hoc test. *P < 0.05 (significantly different from 0 h REST); **P < 0.05 (significantly different from 0 h REST and 0 h PEX). D: p⁶⁴²ThrAS160; data were analyzed with 1-way ANOVA and the Student-Newman-Keuls post hoc test. *P < 0.05 (significantly different from 0 h REST); **P < 0.05 (significantly different from 0 h REST, 0 h PES-buffer, 0 h PEX, and 0 h PEX/PES-buffer). Data are means ± SE, n = 6–8/group.
