Comparison the effect of aerobic training and diet on Body Composition and Metabolic Syndrome Indexes in overweight and obese women

Metabolic Syndrome (Mets) is a cluster of risk factors such as obesity، hyperglycemia، hypertension، dislipidemia which increases cardiovascular disease and type 2 diabetes mellitus. The purpose of this research was to investigate comparison the effect of aerobic training and diet on BMI and Metabolic Syndrome Indexes in overweight and obese women. Twenty one patient female volunteers were selected. After the complement of questionnaires، they were randomly divided into two groups; a) aerobic training with diet group (n=11) and b) diet group (n=10). The first group who took part in weekly group sessions for instructing on weight loss (low calorie diet) with the exercise. The second group who took part in weekly group sessions for instruction on weight loss (low calorie diet). Anthropometric characteristics (PBF، BMI، WHR، WC)، VO2peak، and risk factors of metabolic syndrome such as blood pressure، glucose and total cholesterol were measured in several times. Data were analyzed by GLM-Repeated Measures in significance level of P<0/05. Both groups showed a significant reduction in weight، BMI، body Fat percent، mean arterial and systolic blood pressure and an increase in VO2max. Only the first group (aerobic training with diet group) showed a significant decrease in waist circumference، diastolic blood pressure and cholesterol. The Combined program (aerobic training with diet) is more effective on BMI، lowering blood pressure and abdominal fat and provides improvements in Metabolic Syndrome Indexes in overweight/ obese women.
