Data are presented as mean±sd, unless otherwise stated. H-IMT: high-intensity inspiratory muscle training; S-IMT: sham inspiratory muscle training; BMI: body mass index; FEV1: forced expiratory volume in one second; % pred: per cent of predicted; FVC: forced vital capacity; FRC: functional residual capacity; TLC: total lung capacity; RV: residual volume; DL,CO: single-breath diffusing capacity for carbon monoxide. #: predicted normal values derived from 37–39. *: p<0.05 compared with baseline measures. 1 mmHg = 0.133 kPa.
