Obesity Clinical Trial
Official title:
Effects of Bariatric Surgery on Inspiratory Metaboreflex in Metabolically Healthy Obese and Obese Subjects With Metabolic Syndrome
The hypothesis of this study is that reductions in body weight could improve inspiratory muscle function attenuating the inspiratory metaboreflex in metabolically healthy obese individuals and obese individuals with metabolic syndrome.
Introduction: Peripheral metaboreflex activation appears to be exacerbated in obese individuals with metabolic syndrome. Interestingly, bariatric surgery attenuates the peripheral metaboreflex. Obese individuals have impaired inspiratory muscle function, which can be reversed by the reduction in body weight. Therefore, bariatric surgery could attenuate inspiratory metaboreflex in metabolically healthy obese individuals and obese individuals with metabolic syndrome. Objectives: To investigate the effects of bariatric surgery on inspiratory metaboreflex in metabolically healthy obese individuals and in obese patients with metabolic syndrome. Patients and Methods: A sample comprising of 15 obese subjects with metabolic syndrome, 15 obese subjects without metabolic syndrome and 15 healthy nonobese individuals. These subjects will be submitted to pulmonary function, respiratory muscle strength, inspiratory muscle resistance, exercise tolerance, quality of life, autonomic cardiovascular control and the inspiratory metaboreflex evaluation. The evaluations performed in obese patients with and without metabolic syndrome pre-surgery will be repeated 6 months after bariatric surgery. ;
