Background Most patients with severe COPD are limited by dyspnea and are obliged to
exercise at low intensity. Even those undergoing training do not usually have increased
peak oxygen uptake (o 2). One-legged exercise, at half the load of two-legged exercise,
places the same metabolic demands on the targeted muscles but reduces the ventilatory
load, enabling patients to increase work capacity. The purpose of this study was to
determine whether one-legged exercise training would improve aerobic capacity compared …
