Comparison of Concurrent Aerobic, Resistance and Combination (Aerobic + Resistance) Training on Serum Levels of Leptin, Atherogenic Index of Plasma and Cardiovascular Risk Factors in Obese Inactive Student Girls

Background and Objectives: Obesity and overweight in addition to cardiovascular and metabolic diseases, greatly effects reproductive health as well. Although the positive effects of exercise on weight control and minimizing cardiovascular risk factors has been proven, the effects may vary depending on the type and intensity of the exercise. Therefore, the aim of this study was to compare the effect of 6 weeks of aerobic, resistance and combined training on the serum leptin levels and cardiovascular risk factors in inactive obese girls. Materials and Methods: Twenty-eight obese inactive girl volunteers of age between 20-27 years old participated in this study. The subjects were randomly placed into one of four groups (aerobic, resistant, combined and control). Serum levels of leptin, body mass index, body fat percentage, lipid profile and WHR were measured at baseline and after exercise training. Training program lasted for six weeks and it was carried out 3 times per week. Data analysis was performed using one-way analysis at a (P < 0.05). Results: After 6 weeks of exercise training, serum levels of leptin in all three groups decreased significantly compared to the control group (P < 0.001). Also, six weeks of aerobic, resistance and combined training significantly reduced body fat percentage, body mass index, cholesterol and triglycerides (P < 0.001). In comparison between the groups, combined exercises had a more favorable effect on reducing leptin levels and cardiovascular risk factors. Conclusions: Combined exercise appears to be more effective in reducing serum leptin and cardiovascular risk factors in inactive obese girls
