Inclusion criteria for COPD patients were: forced expiratory volume in one second (FEV1) / forced vital capacity (FVC) ratio < 0.7 and FEV1 < 60% of predicted; clinical stability for at least 3 months prior to the study; nonsmokers; no participation in a regular physically active program in for the last 6 months; and presentation of dyspnea under low and medium physical effort. Inclusion criteria for CHF patients were: previous history of stable symptomatic heart failure due to left ventricular systolic dysfunction, documented in at least six months (left ventricular ejection fraction < 45 % predict); no recent hospitalizations and no history of pulmonary disease or angina. Subjects in the control group were free of chronic pulmonary, cardiovascular, immune, and metabolic disease.
