Ever-increasing incidence of obesity and related multiple psychological and physiological problems converted it into a global epidemic, while sedentariness is considered as one of the main obesity-causing factors. Chemerin is a new adipokine that its serum level increases in obese patients. The purpose of this study was to survey effect of twelve weeks aerobic training on chemerin, active ghrelin, and appetite in sedentary obese men.
Method: In a semi-experimental study, twentyone sedentary obese men were randomly placed in two groups: aerobic training (n=10, 27.8±3.2 yr, 93.5±7.1 kg, 31.7±3.4%, 32.0±3.5 kg/m2) and control group (n=11, 26.7±2.6 yr, 92.9±6.3 kg, 31.4±3.2 %, 32.3±2.8 kg/m2). General characteristics of subjects, circulating levels of chamerin and ghrelin (using ELISA kits), and appetite (using Council on Nutrition Appetite Questionnaire) were assessed before and after training. Aerobic training protocol consisted of twelve weeks pedaling on cycle ergometer (3 sessions per week, intensity 60-70% of reserved heart rate, duration of each session 20-40 min). Data analyzed by SPSS16 software. Statistical significance was accepted at P
