Data are presented as mean±sem. LVR: lung volume recruitment; RMW: respiratory muscle weakness; TLC: total lung capacity; VC: vital capacity; IC: inspiratory capacity; FRC: functional residual capacity; ERV: expiratory reserve volume; RV: residual volume; PEF: peak expiratory flow; PCF: peak cough flow. *: p<0.05 for RMW versus control subjects.
