Introduction: Bariatric surgery, when indicated, helps to reduce total body mass. However, for medium- to long-term efficacy, regular physical exercise is recommended as an adjuvant treatment to surgery. Objective: To verify, through a systematic review, the effect of combined training on the body composition of adults undergoing Roux-en-Y gastric bypass surgery (RYGB). Methods: The electronic search was carried out in the Pubmed, Scielo, and Lilacs databases, in English, Portuguese, and Spanish languages. Only randomized controlled studies with a combined training protocol after RYGB were included. Results: 2071 articles were identified, of which only six were eligible for this review. With a total of 272 participants, five of the articles analyzed had patients of both sexes in their sample and one had only women. Physical exercise attenuated the loss of bone mineral density in different regions (-1.87%-2.91%; p = 0.007-0.038), as well as preventing body mass gain. On the other hand, only the study by Herring et al. (2017) showed a greater reduction in body mass in subjects who performed physical exercise (- 2.4kg; p = 0.003). Finally, the assessment of muscle strength showed inconclusive data. Conclusion: The lack of studies with high methodological quality and low risk of bias, as well as the inadequate choice of assessment instruments to obtain measures of body integrity, has led to a significant reduction in body mass.
