Brief Summary

Introduction: Studies have shown the influence of exercise on sleep architecture and efficiency, although its protocols, procedures, effects and mechanisms of action have not been clearly explained and documented in the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS), which is thought to be the main sleep disorder due to its high prevalence and clinical, social and cognitive consequences. Objective: To evaluate the effect of inspiratory muscle training (IMT) in OSAHS, by analyzing their influence on the quality of sleep, inspiratory muscle strength and polysomnography parameters. Patients and Methods: Controlled and randomized clinical trial involving 75 patients with OSAHS diagnosed by polysomnography. Measurements of maximal inspiratory pressure (MIP) will be performed. Pittsburgh scale Epworth, Sleepiness Scale, Short Form-36, and Berlin / Stanford questionnaires will be used for assessment of sleep quality, daytime sleepiness, health related quality of life quality of health, and the evaluation of snoring. Patients of the intervention group will undergo IMT with an initial load of 40% of MIP. The intervention will be performed daily for 12 weeks employing the exercise inspiratory device (POWERbreathe, HaB Ltd, UK). The main end point will be the effect of the training program on the index of apnea/hypopnea (IAH) assessed by polysomnography. Secondary end points will include effects of the training program on: the quality of sleep, inspiratory muscle strength, the health related QOL. Expected Results: if the hypothesis is confirmed, there will be improvements on the apnea / hypopnea index, on the quality of sleep and on the health related QOL.

Study Arms (2)

Intervention

EXPERIMENTAL

Procedure: Inspiratory muscle training with powerbreathe with a linear pressure resistance using an inspiratory load of 40% of maximal inspiratory pressure (adjusted weekly), seven days a week, 30 exercises daily for 12 weeks.

Device: Inspiratory muscle training with powerbreathe

Control

NO INTERVENTION

Procedure: Training with the same equipment but without load-generating resistance.

Interventions

Participants will be submitted to a linear pressure resistance (Powerbreathe) with an inspiratory load of 40% of maximal inspiratory pressure (adjusted weekly), seven days a week, session duration of 30 exercises for 12 weeks.
