Protein expression of phosphorylated AMP-activated protein kinase (AMPK) and proliferator-activated receptor gamma-coactivator-1 alpha (PGC-1α) in the extensor digitorum longus (EDL) and soleus muscles. Phosphorylated AMPK (a: EDL, b: soleus) and PGC-1α protein expression (c: EDL, d: soleus) in the EDL and soleus muscles as determined by western blot analysis. Entire images of western blotting are shown in online Additional file 1: Fig. S7 and S8. Values are presented as mean ± standard error of the mean. SD-Cont group, n = 5; SD-Ex group, n = 5; SDT-Cont group, n = 6; and SDT-Ex group, n = 6. ^**P < 0.01 vs. the SD-Cont group, ^†P < 0.05 and ^††P < 0.01 vs. the SD-Ex group, and ^§P < 0.05 vs. the SDT-Cont group
