The Effects of 12 Weeks of Spinning Exercises on Ghrelin Hormone Levels and Body Composition of Overweight Adolescents with the Moderator Role of Gender

Introduction: The rising incidence of obesity among adolescents, coupled with the heightened risk of associated health issues, has prompted researchers to explore a range of weight loss exercises and the underlying mechanisms that contribute to their effectiveness.Objective: The aim of the current research was to study the effect of 12 weeks of spinning training on ghrelin hormone levels and body composition of overweight teenagers, male and female.Methods: The current research was semi-experimental. 28 teenage girls (mean age of 13.2 years) and 28 teenage boys (mean age of 14.5 years) with overweight were randomly divided into four groups: exercise-boy, exercise-girl, control-boy and control-girl. The percentage of fat and fat-free mass was measured using body composition measuring device model 3 made in South Korea and the level of ghrelin hormone was measured by ELISA method; The exercise groups performed Spinning exercises three times a week for 12 weeks. Analysis of covariance was used for data analysis.Results: The results of 2-factor covariance analysis showed that spinning exercises led to a decrease in body fat percentage and an increase in ghrelin hormone, and the effectiveness of spinning exercises was significantly higher in girls than in boys.Conclusion: Spinning exercises are useful for the body composition of overweight adolescents and it seems that the increase in the amount of ghrelin hormone plays an important role in the effect of this type of exercises, especially in girls. Spinning exercise can be utilized to facilitate weight loss and enhance body composition of adolescents.
