IMT, inspiratory muscle training training group; PLA, placebo training group; FVC, forced vital capacity; FEV1.0, forced expiratory volume in 1 sec; PEF, peak expiratory flow; P Imax, maximal inspiratory mouth pressure; P Emax, maximal expiratory mouth pressure. Data are given as mean(SD).

Significantly different from pretraining; IMT group P Imax difference pre‐ to posttraining P = 0.003, 95% CI +9.0 to +26.6 cmH2O; IMT group P Emax difference pre‐ to posttraining P = 0.012, 95% CI +7.1 to +35.3 cmH2O.
