Summary

Background and Objective: Chronic Obstructive Pulmonary Disease (COPD) is characterized by progressive airflow limitation associated with an inflammatory response. The aim of the study was to evaluate the influence and the association of respiratory variables on exercise capacity in COPD patients. Methods: A cross-sectional study evaluated 39 COPD patients to obtain forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). Respiratory muscle strength (RMS) was evaluated at its maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) components. Exercise capacity was assessed by Six-Minute Walk Test (6MWT) and Incremental Shuttle Walking Test (ISWT). Results: FEV1 (39.8±15.3%predicted) and FVC (60.2±17.1%predicted) were reduced, which classified them in stages II (21%), III (51%) and IV (28%). MIP (92.7±14.6% predicted) and MEP (97.6±19.0% predicted) were within the expected values. A moderate correlation was observed between the ISWT vs FEV1 (r=0.35;p=0.02) and ISWT vs FVC (r=0.42;p
