Obesity and physical activity: the benefits of high-intensity intermittent exercise in the process of weight loss
Abstract
Exercise together with the rehabilitation food, has been used as the main tool in programs for non-medical weight loss. Some of the likely mechanisms by which exercise can help maintain body and weight loss is the increase in daily energy expenditure and basal metabolic rate, increased muscle mass, increased oxygen consumption and optimizes the process of mobilization and use of fat. Accordingly, high-intensity intermittent exercises have been used as a strategy for the treatment of weight loss. The results presented in this study to review, demonstrate that high-intensity intermittent exercises used in physical training programs aimed at weight loss, can help in a major reduction of body fat in subjects with overweight and obesity. The objective of the study was to evaluate the advantages (or disadvantages) of the method of using high-intensity exercise, through various incentives or breaks, the reduction of body fat and maintenance of body composition. The method has advantages at the implementation and, mainly, in the post office, which already has higher levels of rest metabolic rate and EPOC for a period of time compared with the continuous training of low intensity. This suggests that the model of training with sprints of high intensity intervals produces a higher total energy expenditure (during the execution and return to the levels of rest), and this is crucial when we refer to intentional imbalance of energy balance.
