Changes in AMPKα and ULK1 signaling pathways in response to 8 weeks of resistance exercise. a Representative Western-blot images of AMPKα, p-AMPKα^Thr172, ULK1, p-ULK1^Ser555, and p-ULK1^Ser757 in each group. b Quantification of AMPKα, p-AMPKα^Thr172, and p-AMPKα^Thr172/AMPKα ratio. c Quantification of ULK1, p-ULK1^Ser555, and p-ULK1^Ser555/ULK1 ratio. d Representative Western-blot images of ULK1, p-ULK1^Ser757, and p-ULK1^Ser757/ULK1 ratio in each group. Comparisons of each target protein expression were made after normalization to GAPDH. SC sedentary control group, RE resistance exercise group. *p < 0.05 vs. SC
