The Effect of a Single Circuit-Resistance and Aerobic Exercise on Plasma Obestatin Levels in Well-Trained Females

Document Type : Original Article

Abstract

Introduction: Obestatin is recently described as a gastrointestinal (GI) hormonal, which is involved in the 
pathophysiology of obesity. It decreases food intake and body weight by decelerating gastric emptying. The 
purpose of this study was to investigate the impact of a single circuit-resistance exercise and aerobic exercise 
on plasma obestatin and growth hormone (GH) in well-trained females. 
Material and Methods: 24 participants from Khorasani female athletes were randomly selected and 
assigned into three groups: control (N=8), circuit-resistance exercise (RE) (N=8) and aerobic exercise (AE) 
(N=8). Blood samples were collected from all the participants before and immediately after the exercise 
protocol.
Results: Changes in plasma obestatin levels were not significant within and between groups. Plasma GH 
concentrations were significantly higher in experimental groups compared to the control group. 
Discussion and Conclusion: The data indicated that although circuit-resistance and aerobic exercise resulted 
in a significant change in GH levels, they had no effect on plasma obestatin levels
