Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Increased electrical activation of the diaphragm after 5 and 9 weeks of inspiratory muscle training, verified through the median frequency and the RMS (root mean square) obtained in surface electromyography exam from observation of a variation at least 10% in pre and post intervention measurements. | — |
Secondary
| Measure | Time frame |
|---|---|
| Increase in diaphragmatic mobility after 5 and 9 weeks of inspiratory muscle training, assessed through the ultrasound exam from the observation of a change of at least 8% in pre and post intervention measurements. Increased diaphragmatic thickness after 5 and 9 weeks of inspiratory muscle training, assessed through the ultrasound exam from the observation of a change of at least 20% in the pre and post intervention measurements. Increased respiratory muscle strength after 5 and 9 weeks of inspiratory muscle training, evaluated by manovacuometry, from the observation of a change of at least 40% in the pre and post intervention measurements. Increase in respiratory muscle endurance after 9 weeks of inspiratory muscle training, observed by maximum voluntary ventilation technique, from the observation of a change of at least 8% in pre and post intervention measurements. Increased aerobic capacity (maximal oxygen uptake) after 9 weeks of inspiratory muscle training, verified by the cardiopulmonary exercise testing, from the observation of a change of at least 20% in the pre and post intervention measurements. | — |
