Interactive effect of regular aerobic training and milk consumption on some inflammatory markers and lipid profile in overweight boys

Abstract

Introduction: Several studies have reported the protective effects of aerobic training and milk consumption in obese people, but the exact mechanisms of its effect on the inflammatory markers is not well known. The aim of this study was to determine the interactive effect of eight weeks regular aerobic training and milk consumption on levels of endothelin-1, nitric oxide, interleukin-6, Galectin, and lipid profile in immature overweight boys. Materials and Methods: In a quasi-experimental study 28 boys (8 to 12 years old) with BMI≥25 were selected and divided into 4 groups including exercise, milk, exercise-milk and control randomly. Exercise training was done with 45 to 60% of maximum heart rate during 8 weeks (3 sessions per weeks).Supplement consumer groups received 236 ml low fat milk per day. Before and after 8 weeks, blood sample were collected during the 14 hour fasting condition to measure the inflammatory markers and lipid profiles. Results: After eight weeks of supplementation and exercise, the mean concentrations of endothelin, galectin and IL-6 decreased, and nitric oxide increased. Most of the changes occurred in exercise-supplement group. VLDL, LDL and TG concentrations were decreased, though in contrast, HDL level was increased (P
