Protein expression of insulin-like growth factor-1 (IGF-1) and phosphorylated Akt related to muscle hypertrophy in the extensor digitorum longus (EDL) and soleus muscles. Protein expression of IGF-1 (a: EDL, b: soleus) and phosphorylated Akt (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 S2. 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 < 0.05 and ^**P < 0.01 vs. the SD-Cont group; ^†P < 0.05 and ^††P < 0.01 vs. the SD-Ex group
