Effect of eight weeks roping exercise on visfatin level and insulin resistance in obese adolescens

Background: Visfatin is a newly characterized adipokines which is highly expressed in visceral adipose tissue. Recent studies have demonstrated that visfatin levels in obese and overweight increases. The aim of this study was assessing the Effect of eight weeks roping exercise on visfatin level and insulin resistance in obese adolescens. Methods: Thirty overweight or obese adolescents were willing to cooperate voluntarily and available which they randomly were divided in two groups: experimental group (height 165.28 cm, weight 94.11 kg, age 13.73 years old) and control group (height 164.54 cm, weight 86.8 kg, age 13.93 years). Then, the experimental group was influenced by increasing roping exercise program which consisted of 8 sessions per week,. While the control group received no intervention but were followed. Variables including weight, body fat percentage, body mass index (BMI), VO2max were measured in both groups before and after exercises. Blood samples were collected in two stages, 48 hours before and after exercise to measure of glucose, Visfatin levels and insulin resistance. Paired t-test was used for intergroup comparisons and independent t-test was used for comparison between the two groups. All statistical calculations were performed by SPSS software version 19. Results: The findings showed that eight weeks roping exercises no significant differences in fat percentage, WHR, glucose, insulin, and Visfatin levels and insulin resistance index among the two groups were detected. Significant decrease in body composition including weight, and BMI was observed in case group (p<0.05). Conclusions: One can conclude that the 8-week roping exercise cannot reduce the levels of visfatin, but can reduce the BMI.
