Considered a major public health problem, obesity is the accumulation of excess body fat in such a way that it can cause health problems to individuals, being caused mainly by the mismatch between the number of calories consumed and spent, that is, a consequence of sedentary lifestyle and poor diet. Due to its countless consequences, an increasing number of studies show the benefits of a high intensity interval training program (HIIT) for obese practitioners, since a large part of the population does not practice physical exercises due to lack of time due to their hectic routines, HIIT being a practice proposal with less time. Therefore, the objective of this work is to analyze the studies that investigated the effects of high intensity interval training (HIIT) on the body composition of its practitioners. From a literature review in the SciELO, Lilacs and PubMed databases, eleven articles were selected to compose the results, which showed a significant improvement in the body composition of HIIT practitioners. Thus, it is possible to conclude that these protocols are shown as alternatives for the treatment of obesity, since they can promote significant reductions in body composition and improvements in aspects such as the increase in lean mass. The literature review samples were from elderly diabetic women with excess weight and obesity, sedentary adults with excess weight and associated with metabolic syndrome.
