Values are means ± SEM, n = 8/group. COPD: Chronic Obstructive Pulmonary Disease, BMI: body mass index, FFMI: Fat-free mass index, FEV1: forced expiratory volume in one second, Dlco: diffusing capacity for carbon monoxide, FVC: forced vital capacity; ITGV: intrathoracic gas volume; TLC: total lung capacity. There were no significant differences between the groups.
