Abstract

More than half of the Brazilian population is overweight or obese, which configures this condition as a public health problem. Lifestyle changes are recommended as the first line of obesity treatment. However, in cases of grade III obesity, bariatric surgery is the main indication, in addition, it is an alternative treatment for some chronic conditions associated with obesity, such as type II diabetes. Most patients undergoing bariatric surgery have an inactive lifestyle and additionally spend a lot of time on sedentary behavior. Thus, despite all the benefits, it is observed that the surgical procedure shows little or no change in the sedentary behavior and physical activity level in these patients. In addition, little is known about the effects of reducing sedentary time in this population. In this sense, the present project aims to investigate the effects of successive interruptions to prolonged sedentary behavior (ie, 3 min of light physical activity (walking) every 30 min over 8 hours) versus 30 min of physical exercise followed by behavior prolonged sedentary or just sedentary behavior (control condition), in a controlled environment, in physiological parameters in patients who underwent to bariatric surgery. For this purpose, an acute laboratory study will be conducted. The findings of this project will generate a unique body of knowledge, which has the potential to influence areas such as Exercise Science, Medical Sciences and Basic Sciences.
