Efeitos do treinamento intervalado de alta intensidade no processo de emagrecimento de adultos obesos

Abstract

Objective: To investigate the effects of high-intensity interval training on the weight loss process of obese adults. Method: Indirect bibliographic search carried out in the U.S. National Library of Medicine (PubMed) database, with publications from 2013 and 2023. The search was carried out using the PICo strategy and clinical trial studies and randomized and controlled clinical trials. 132 studies were identified, six of which were selected for this research. Results: Studies show significant results in reducing fat mass and reducing the level of obesity through high-intensity interval training, even with variations in program duration and without the association of low-calorie diets. Training protocols show positive results regardless of whether they are performed on machines or freely, just maintaining the standard of prescribing a long or short interval method. Significant improvements in blood pressure, VO2 and an increase in lean mass were also observed. Conclusions: High-intensity interval training is highly effective in the weight loss process and in controlling and combating obesity. It has shown evidence that it produces improvements in body composition and metabolic health, through simple exercises that can be done both freely and on more sophisticated devices.
