Effects of Acute Aerobic Exercise on Skeletal Muscle Transcriptomics in Lean vs Overweight/Obese Men

Acute aerobic exercise has been shown to improve skeletal muscle mitochondrial function and completeness of fatty acid β-oxidation which contribute to improved insulin sensitivity. The effectiveness of acute exercise on improving mitochondrial adaptations, leading to improved insulin sensitivity, in overweight/obese (Ov/Ob) individuals is controversial. This study aimed to determine the effects of acute exercise on epigenetic regulation of genes involved in skeletal muscle mitochondrial adaptations in lean vs Ov/Ob men.
