The effects of Rope Jumping Training and dark chocolate on anthropometric measurements and omentin-1 levels in obese adolescents

Introduction: The purpose of the present study was to investigate the simultaneous and independent effects of a Rope Jumping Training course and dark chocolate consumption on anthropometric indices and omentin-1 levels in obese adolescents. Materials and Methods: 40 obese teenagers were randomly divided into four homogeneous groups: Rope Jumping Training (1), dark chocolate (2), Training + dark chocolate (3) and control (4). Subjects in the second and third groups daily consumed 30 grams of dark chocolate (83 percent cocoa) for six weeks. Also, subjects the first and third groups performed Rope Jumping Training for six weeks (40 minutes a day, 5 days a week). Before and after six weeks anthropometric indices and blood samples were taken to measure the biochemical values of the subjects. Results: After performing the protocol, the values of omentin -1 increased, and weight and BMI showed a significant decrease in the first, second and third groups. While the percentage of fat and WHR only decreased significantly in the first and third groups (P≤0.05). The intergroup analysis also showed significant changes in omentin -1, weight, BMI, body fat percentage and WHR in the first, second and third groups compared to the fourth group, with the most of these changes seen in the third group (P≤0.05).  Conclusion: Rope Jumping Training and the use of dark chocolate independently and simultaneously improve the body composition and increase the levels of omentin-1 in obese adolescents, which results in better results at the same time.
