Significant difference between groups postintervention (). IMT: inspiratory muscle training; P-IMT: placebo-inspiratory muscle training; FEV1: forced expiratory volume in 1 sec; FVC: forced vital capacity; MVV: maximal voluntary ventilation; PImax: maximum inspiratory pressure; VO₂max: maximal oxygen consumption; VCO₂max: maximal carbon dioxide exhaled; HRmax: maximal heart rate; SBP: systolic blood pressure; DBP: diastolic blood pressure.
