چکیده

Background: Visfatin is an adipocytokine new adipocyte which is highly expressed in visceral adipose tissue and has similar effects with insulin As the obesity is a worldwide health issue and visfatin is associated in obesity and insulin resistance.The purpose of this study was to investigate the effect of moderate intensity interval training on visfatin and insulin resistance index in obese girls. Materials and Methods: In this semi-experimental study, ۱۸ obese girls aged ۱۲ -۱۴ years old were selected according to inclusion and exclusion criteria and randomly divided into training (n=۱۰) and control (n=۸) groups. The training program lasted eight weeks, trice weekly for ۳۰ minutes each session. running at ۷۰% of the target heart rate for first ۴-week and ۷۵ % for the rest of the protocol. Blood samples were taken for measuring visfatin, insulin, and glucose ۲۴ hours before and ۴۸ hours after the last session. Insulin resistance, visfatin, glucose, Vo۲max, fat percent, BMI, and body weight were measured using specific methods. Analysis of covariance ANCOVA was used. The significance level was considered as p < ۰.۰۵. Results: The results of the current paper showed that visfatin , Insulin resistance index, insulin and maximal oxygen consumption (vo۲max) were increased in experimental group, which was significant only for the values of vo۲max (P = ۰.۰۰۱). Body weight, body fat percentage, body mass index or BMI and glucose significantly decreased in the experimental group. Conclusion: Today obesity is a worldwide health issue and in this paper we showed that long training sessions with adequate intensity and volume have beneficial effects on health issues and they are suggested to make optimal changes in visfatin levels and reduce insulin resistance in obese girl.
