Resistance exercise training improves skeletal muscle metabolism. A Gastrocnemius triglyceride (TG) level was measured, n = 5. B Western blotting analysis of GLUT4 and PGC-1α protein expression in skeletal muscle, n = 3–4. C qPCR analysis of skeletal muscle fiber type gene expression in skeletal muscles, n = 4. D Expression of fatty acid oxidation genes in resistance exercise-induced skeletal muscles, n = 4. Values are presented as mean ± SEM. Significant differences were determined using an unpaired two-tailed Student’s t-test. *p < 0.05
