“…This is due to the fact that this training model stimulates different metabolic pathways in the same training session. Studies using young population with HS have shown improvements in body composition through different training protocols, whether systematized training occurring with adolescents, and even physical exercises through predominantly aerobic activities with children 10,11 . However, analyses were performed without adjustment for confounding factors, and the results found may have several explanations, not the effect of the exercise itself.…”

-Physical exercise is one of the forms of prevention and treatment of obesity and associated diseases such as hepatic steatosis. The aim of this study was to analyze whether hepatic steatosis interferes in the effect of physical exercise on the body composition of obese children and adolescents. The sample consists of 40 obese individuals, 13 children (8.17±1.33 years) and 27 adolescents (12.28±1.36 years). Total and segmental body composition was estimated by DEXA. Anthropometric measurements were performed, as well as ultrasound examination of the liver to measure intra-abdominal and subcutaneous fat, and to diagnose hepatic steatosis (HS). The intervention consisted of 20 weeks, with recreational/competitive activities being applied to children and, for adolescents, concurrent training (aerobic and resistance). The Levene's, repeated-measures ANOVA and effect size tests (ES) by Eta-Squared were performed. It was observed that, although not statistically significant, analyzing the effect size, physical activity in both children (body fat ES effect time= 0.210 and ES effect group= 0.208; fat mass ES effect group= 0.338; fat android ES effect Interaction= 0.267), and adolescents (intra-abdominal fat ES effect group= 0.230) regardless of whether or not HS was effective in reducing body fat. Therefore, exercise was effective in improving the body composition of obese children and adolescents, regardless of HS.Key words: Adolescent; Child; Exercise; Fatty liver; Obesity.
