Data are presented as mean±sd or n (%), unless otherwise stated. Endurance time refers to performance on a cycle ergometer at 80% of peak workload. p-values are for unpaired t-tests. δ: change in; SWT: shuttle walk test; DL,CO: diffusing capacity of the lung for carbon dioxide; RV: residual volume; TLC: total lung capacity; FRC: functional residual capacity; FEV1: forced expiratory volume in 1 s; EELV: end-expiratory lung volume; SGRQ: St George’s Respiratory Questionnaire total score. #: Chi-squared test.
