Protein expression related to vascular endothelial cells in the extensor digitorum longus (EDL) muscle. Protein expression of CD31 (a), insulin receptor substrate 2 (IRS2) (b), and phosphorylated endothelial nitric oxide synthase (eNOS) (c) as determined by western blot analysis. Entire images of western blotting are shown in online Additional file 1: Fig. S9 (a, c, e) and S10 (a, c, e). 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 vs. the SD-Cont group, ^†P < 0.05 vs. the SD-Ex group, and ^§P < 0.05 vs. the SDT-Cont group
