Figure Lengend Snippet: Resistance exercise exceeds the benefits of endurance exercise in ameliorating metabolic dysfunction. Following 8 weeks of diet and exercise interventions, all mice were assessed for their metabolic function by GTT, ITT, and skeletal muscle response of Akt and AS160 phosphorylation to injection of insulin measured by Western blot. (A–C) HOMA-IR taken after an overnight fast for baseline glucose and insulin. (D and E) GTT from 0–120 min and calculated AUC; colored * indicates significant difference from NC-SED. (F and G) ITT from 0–60 min and calculated AUC; colored * indicates significant difference from NC-SED. (H–N) pAkt stimulation, AS160 S318, and AS160 T642 in hindlimb muscles before and after insulin injection and the pre–post ∆ in phosphorylation. (O and P) Total and phosphorylated 4E-BP1. (Q–T) Western results for Raptor, COX4, LC3 II/I, and ubiquitin staining. Representative western blot images inset right. Data presented as mean ± standard error of the mean. Statistical analysis performed by analysis of variance between groups: * p < 0.05, ** p < 0.01, *** p < 0.001, and **** p < 0.0001. NC-SED n : 8–16 (white); HFD-SED n : 8–18 (red); HFD-R EX n : 8–16 (blue); HFD-E EX n : 8–15 (green). 4E-BP1 = Eukaryotic translation initiation factor 4E binding protein; Akt = protein kinase B; AS160 = Akt substrate 160; COX4 = cytochrome c oxidase 4; CS = citrate sythase; E EX = endurance exercise; GAPDH = glyceraldehyde 3 phosphate dehydrogenase; GTT = glucose tolerance test; HFD = high fat diet; HOMA-IR = homeostatic model assessment for insulin resistance; iAUC = integrated area under the curve; ITT = insulin tolerance test; LC3 II/I = microtubule-associated protein light chain 3; NC = normal chow; pAkt = phospho-Akt; R EX = resistance exercise; SED = sedentary; Ub = ubiquitin.
