ABSTRACT
Retinol-Binding Protein 4 (RBP4) is a vitamin A transport protein that plays a role in metabolism. The aim of this study was to analyze the effect of aerobic exercise and a high-carbohydrate diet on the immunoexpression of RBP4 in the skeletal muscle of rats. A total of 28 male rats were divided into four groups: normal diet, sedentary (K1); high-carbohydrate diet, sedentary (K2); normal diet, exercise (K3); and high-carbohydrate diet, exercise (K4). The rats in the exercise groups were subjected to running on a treadmill 5 days per week for 16 weeks with a speed of 15–23 m/min for 30 minutes. At the end of the study, RBP4 immunoexpression in the skeletal muscle of rats was examined. The results revealed that the RBP4 immunoexpression levels of all the groups were not significantly different. However, there was a weak correlation of body weight and exercise with the immunoexpression of RBP4.
