Effects of an exercise program on hepatic metabolism hepatic fat and cardiovascular health in overweight/obese adolescents from Bogotá Colombia (the HEPAFIT study): study protocol for a randomized controlled trial

摘要

BackgroundA considerable proportion of contemporary youth have a high risk of obesity-related disorders such as cardiovascular disease, metabolic syndrome, or non-alcoholic fatty liver disease (NAFLD). Although there is consistent evidence for the positive effects of physical activity on several health aspects, most adolescents in Colombia are sedentary. It is, therefore, important to implement strategies that generate changes in lifestyle. The HEPAFIT study aims to examine whether a 6-month exercise program has benefits for hepatic fat content and cardiovascular health outcomes among overweight/obese adolescents from Bogotá, Colombia.
