Values are means ±s.e.m. Exercise data depict the results of the incremental exercise test in room air. FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; WRmax, maximal work rate, 
, maximal oxygen uptake, RER, respiratory exchange ratio, 
, maximal minute ventilation, VTmax, maximal tidal volume, fmax, maximal breathing frequency.
