Values are means ± SD. COPD: chronic obstructive pulmonary disease; BMI: body mass index; EF: left ventricle ejection fraction; FEV1: forced expiratory volume in the first second; FEV1/FVC: forced expiratory volume in the first second to forced vital capacity ratio; MIP: maximal inspiratory pressure; SpO2: peripheral oxygen saturation; RF: respiratory frequency;
