Figure 2 The PI_max values (mean ± SD) at rest and on the 5th and the 10th min of recovery after maximal cardiopulmonary exercise test. (A) Values before and (B) after intervention for the placebo inspiratory muscle training group (P-IMT) and the inspiratory muscle training group (IMT). Two-way ANOVA for repeated measurements: IMT versus P-IMT (p < 0.01 for group, training, and interaction effects). Multiple comparisons by the Tukey test: *5th minute versus rest (p < 0.05); 10th minute versus rest (p < 0.05); 10th minute versus 5th min (p < 0.05).
