Extracellular signal-regulated kinase (ERK)1/2 and ribosomal protein (rp)S6. Data represent phosphorylation fold change of (A) ERK1/2 at Thr202/Tyr204 and (B) rpS6 at Ser235/236 at baseline, and 3, 6 and 24 hours after exercise. Representative immunoblot images are shown. *Significantly different from baseline (P < 0.05).
