Vascular reactivity at rest and during exercise in middle-aged obese men: effects of short-term, low-intensity, exercise training

Objective: Although increased blood flow (BF) in exercising muscles is thought to be impaired in obese subjects and may contribute to physical inactivity, data are scarce in this regard and the involvement of endothelium dysfunction remains partly hypothetical. Methods: A total of 16 middle-aged obe...
