Key result
Type 2 diabetes was associated with significantly attenuated leg blood flow responses to acetylcholine and exercise compared with healthy matched controls (P < 0.05).
Why the study?
Do individuals with type 2 diabetes have impaired leg blood flow responses to exercise and endothelium-dependent vasodilation compared to healthy controls?
Population
18 males, comprising 9 with type 2 diabetes and 9 age-, sex-, VO2peak-, and weight-matched healthy controls.
Comparison
Intrafemoral arterial infusions of acetylcholine… vs Healthy matched controls undergoing the same…

Impaired leg blood flow during exercise in type 2 diabetes may limit tolerance and raise ischemia risk; leaves open endothelial-targeted interventions.
Observational (n=18)
Do individuals with type 2 diabetes have impaired leg blood flow responses to exercise and endothelium-dependent vasodilation compared to healthy controls?
p-value: p=< 0.05
Type 2 diabetes impairs leg blood flow during exercise, potentially due to hyperglycemia-induced endothelial dysfunction, which may contribute to peripheral vascular disease.
Kingwell et al. (2003) conducted an observational in Type 2 Diabetes (n=18). Type 2 Diabetes vs. Healthy control subjects was evaluated on Leg blood flow (LBF) responses to acetylcholine and exercise (p=< 0.05). Type 2 diabetes was associated with significantly attenuated leg blood flow responses to acetylcholine and exercise compared with healthy matched controls (P < 0.05).
