Primary
| Measure | Time frame |
|---|---|
| "Expected outcome 1": Assessment of pulmonary function: spirometry will be performed according to the criteria of the American Thoracic Society (ATS) (MILLER et al., 2005). All patients will perform at least three maneuvers, in a sitting position, with a nose clip and attached mouthpiece, they will be instructed to perform maximum inspiration, until the total lung capacity, followed by maximum and continuous forced expiration for a few seconds, until the residual volume. (VR). The forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1 / FVC ratio, peak expiratory flow and intermediate expiratory flows will be determined (PEREIRA; SATO; RODRIGUES, 2007). | — |

| "Expected outcome 2": Respiratory muscle function: to assess respiratory muscle function, a computerized electronic device (KH2; PowerBreathe International Ltd. UK) will be used together with a Breathelink feedback. There will be evaluation by means of the maximum inspiratory pressure (IMP) and the resistance of the respiratory musculature. During the test, patients will remain seated with their arms supported and a nose clip to prevent air leakage out of the device. During the PIM assessment, the patient will be instructed to exhale to the residual volume and then perform a maximum inhalation maintained for as long as possible, neglected when less than 1.5 seconds. This evaluation will be carried out from three to a maximum of eight repetitions, seeking variations of less than 10% in the values ??between them. It will be considered the measure of greatest value. Respiratory muscle resistance will be assessed by an incremental load test, where patients will be instructed to perform the greatest number of breaths. An initial load of 10 cmH2O will be standardized for a period of two minutes. Subsequently, the patient will be instructed to rest for one minute and then a new two-minute cycle will be started, adding another 10 cmH20 to the equipment load. The highest load sustained for at least one minute will be considered the value of the sustained PIM. The test will be interrupted if the participant fails the task or if it is determined by the evaluator that the participant is unable to generate the target pressure. In addition, there will be an interruption in the test if the sensation of dyspnea or fatigue is described by the patient as too uncomfortable to tolerate. The IMP will be assessed before (initial IMP) and shortly after the incremental load test (final IMP) to verify the occurrence of muscle fatigue. The division between the final PIM and the initial PIM will be called the fatigue resistance index (IRF). We will consider the occurrence of reduced respirato | — |
