The Behavior of Maximal Respiratory Pressures, Peak Expiratory Flow and Functional Capacity Between Pilates Method Practitioners

Abstract

Introduction: The Pilates method is a strategy with positive effects not only on the balance and quality of life of its practitioners, but also on respiratory muscle strength and functional capacity. The aim of this study was to assess respiratory muscle strength and functional capacity among individuals practicing the Pilates method and compare them with the values predicted for the Brazilian population. Methods: This is a cross-sectional, observational study carried out among Pilates practitioners (N=30) of both genders, aged between 20 and 66 years, with at least 4 weeks of practice in the modality under study. Measures of lung function (peak expiratory flow) and strength (maximum respiratory pressures) were analyzed, as well as functional capacity using the step test, which were compared with normal values for the study population. The significance level adopted was p < 0.05. Results: the mean maximum respiratory pressures obtained were lower than those predicted for the Brazilian population. On the other hand, the average number of ascents obtained in the 6-minute step test was significantly higher than the predicted average. No statistically significant difference was found for PEF (p=0.687). Conclusion: The Pilates method did not influence the maintenance of maximum respiratory pressures or PEF measurements in its practitioners. On the other hand, this modern form of physical activity promoted an effective increase in functional capacity, as measured by the step test.
