Introduction: Obstructive sleep apnea syndrome (OSAS) is characterized by upper airway obstruction during sleep, which causes systemic effects during wakefulness. Objective: The objective of this study is to assess functional capacity, respiratory muscle strength and peak expiratory flow (PEF) in patients with OSAS. Methods: This is a cross-sectional study held in the city of Patos de Minas/MG in the year of 2019, that included 14 individuals who had severe and moderate sleep apnea. First, the patients answered to a sociodemographic questionnaire prepared by the authors. Then, manovacuometry, PEF and six-minute walk test (6MWT) were performed. Results: Most patients were men (71.4%), obese (78.6%) and hypertensive (57.1%). As results of the tests we obtained - MIP obtained vs predicted = 86.4 vs 102.8 (p = 0.004), MPE obtained vs predicted = 98.5 vs 113.5 (p = 0.05), PEF obtained vs predicted = 381.3 vs 495.8 (p < 0.001) and 6MWT obtained vs predicted = 485.3 m vs 536.6 m (p = 0.03). Conclusion: In this sample of individuals with severe and moderate OSAS, there was a reduction in respiratory muscle strength, PEF, and functional capacity.
