Abstract
This is a retrospective analysis of data in which we explored the association between energy expenditure (EE) and lung function in patients with chronic obstructive pulmonary disease (COPD). A total of 36 participants (20 males; forced expiratory volume in 1 second (FEV1) of 48 ± 15% predicted) underwent measures of indirect calorimetry whilst performing five simple activities of daily living. Maximal voluntary ventilation was the only lung function parameter associated with EE. These data highlight the limited extent to which the FEV1 is related to the functional performance of patients with COPD.
