Abstract
Introduction: Nesfatin-1 is an adipocain expressed in hypothalamus which is the main center for appetite adjustment and energy balance. This research aimed at studying the effects of a series of aerobic exercises on body compounds and nesfatin-1 serum in obese men.
Methods: The research was a semi-experimental one where nineteen men aged 20 – 40 with BMI≥30 were randomly divided into experimental and control groups. First, the examinees’ height, weight, BMI, fat percentage and blood samples were taken in order to measure nesfatin-1, insulin, glucose and resistance to insulin. Then, the examinees in the experimental group participated in the aerobic exercise program. The tools used in this research included height meter, composition air set, Elisa kit and DRG kit. The t, u, Mann-Whitney and sign tests were used to compare data at p < 0.05. The data were analyzed using SPSS19.
Results: After 12 weeks, the weight, fat percentage and BMI reduced significantly in both the experimental and control groups. Comparing the experimental and control groups, the weight, fat percentage and BMI averages were significantly different. All the mentioned variables were insignificant in the control group. However, no significant changes were observed in glucose, insulin, resistance to insulin and nesfatin-1 levels.
Conclusion: According to the findings, in spite of the effects of aerobic exercises leading to weight, fat percentage and BMI reduction, no significant effect on glucose, insulin, resistance to insulin and nesfatin-1 levels in obese men were observed.
