Effects of GLP-1 Infusion Upon Whole-body Glucose Uptake and Skeletal Muscle Perfusion During Fed-state in Older Men

Abstrakt

Ageing skeletal muscles become both insulin resistant and atrophic. The hormone glucagon-like peptide 1 (GLP-1) facilitates postprandial glucose uptake as well as augmenting muscle perfusion - independent of insulin action.

We thus hypothesized exogenous GLP-1 infusions would enhance muscle perfusion and positively impact glucose metabolism during fed-state clamps in older people.
