Performance enhancement in chronic obstructive pulmonary disease

Abstract

Exercise limitation is a hallmark of chronic obstructive pulmonary disease (COPD) and is integral to the associated impaired health status of these patients. The poor exercise tolerance is multifactorial in origin, relating to airflow obstruction, disadvantageous lung mechanics, reduced oxygen delivery and skeletal muscle dysfunction. A number of interventions have been studied to determine whether they can impact on exercise performance. The most evidence-based of these is exercise training, which along with other approaches, both previously investigated and putative, are discussed in this review.
