Data reported as mean±SD and range reported as minimum-maximum value for each measure. Spirometry taken as pre-test values taken after participant had completed all questionnaires on that first visit.
GXT, graded exercise test; BMI, body mass index; FEV1, forced expiratory volume in 1 second; FVC, forced vital capacity; FEF25-75, forced expiratory flow at 25%-75%; FEF50, forced expiratory flow at 50%; VO2max, measure of the maximum volume of oxygen; SD, standard deviation.
