Impact of Metformin on Exercise-Induced Metabolic Adaptations to Lower Type 2 Diabetes Risk

Abstract

Combining metformin with exercise has been proposed to improve glucose homeostasis. However, we primarily discuss evidence suggesting that metformin and other pharmacological agents/dietary supplements (e.g., statins, resveratol, or antioxidants) may in fact oppose exercise-induced benefits on insulin sensitivity and cardiometabolic health. We explore the novel hypothesis that attenuation of oxidative stress from exercise by these exogenous compounds blunts metabolic adaptation.
