Abstract
Background & aim: Orexin is an orexigenic peptide present in the form of A and B in the blood. Orexin neurons respond to a number of metabolic signals that indicate the body's energy status. The present study was carried out to evaluate the effect of six weeks of aerobic training on orexin level, insulin resistance and anthropometric indices in overweight women.
Methods: In the present quasi-experimental study, the statistical population consisted of overweight and inactive women in Bojnourd, Iran,, aged 45-65 years, and BMI 26-29 kg/m2. Twenty-four eligible individuals were randomly divided into two groups of control and exercise. The exercise included aerobic training (with intensity of 60-70% of maximum heart rate reserve). The exercise performed three times per week for six weeks.
Results: The six weeks of aerobic training increased the orexin A level and decreased insulin, glucose, insulin resistance index, weight, BMI, WHR and fat percentage in interventional group. But in control group none of these variables changed significantly after six weeks(P<0.05).
Conclusion: The six weeks of aerobic training increased the orexin A level, decreased insulin resistance and improves anthropometric indices in overweight women. Therefore, obese women are recommended to use these exercises as a preventive method for future diabetes and cardiovascular diseases.
