Purpose:

The purpose of the present study is to determine the effects of increased walking and lower body heating on leg vascular function in patients with type 2 diabetes (T2D).


Study summary:

The notion that habitual aerobic exercise increases insulin-induced vasodilation is largely founded on rodent studies, hence the urgent need for human studies, especially in patients with type 2 diabetes (T2D). For example, it remains unknown if increased walking, the most common form of physical activity, enhances skeletal muscle vasodilator actions of insulin in T2D. In addition, the molecular mechanisms by which exercise improves vasoreactivity to insulin have not been examined in humans. The investigators propose that in T2D patients who are sedentary (i.e., the vast majority), increased leg blood flow with walking or local heating signifies a vital strategy to correct vascular insulin resistance. This study will establish whether increased physical activity and associated hemodynamic forces (e.g., shear stress) are a direct form of vascular medicine in humans.


Criteria:

Inclusion Criteria: Patients with type 2 diabetes who are overweight and obese (BMI 25-50 kg/m2), 35 to 65 years of age, and sedentary (<60 minutes structured exercise/week).
