Data are presented as mean ± SD.

FVC, forced vital capacity; FEV1, forced expiratory volume in the first second; PEF, peak expiratory flow; VC, vital capacity; MVV, maximal voluntary ventilation; FEF25-75, forced expiratory flow at 25 and 75% of the pulmonary volume.

^aWithin-group difference. ^bBetween-group difference. ɳ², partial eta squared indicating effect size.
