Comparison of changes between the groups during the study
| Parameter | Change between baseline and end of training | p value | ||
|---|---|---|---|---|
| PR-SHAM | PR-IMT | Control | ||
| Pimax, inspiratory oxygen pressure; V˙o2 peak, peak oxygen uptake; ISWT, incremental shuttle walking test. | ||||
| p values represent differences between the three groups (using ANOVA) at the time point shown. Numbers in parentheses are 95% confidence intervals. | ||||
