Evaluation of the effect of ۸ weeks of guarana supplement and a selected aerobic training course on lipid profile, insulin resistance, adiponectin and serum insulin in inactive obese women

Introduction:Obesity is one of the most common metabolic disorders in industrialized and developing countries. The aim of this study was to evaluate the effect of ۸ weeks of selected aerobic exercise and Guarna supplementation on some obesity indicators in overweight women. materials and methods: In this quasi-experimental study, ۲۰ women were overweight (body mass index was between ۲۵ and ۳۰ and fat percentage was more than ۳۵%). Average fat percentage of samples it was ۳۳.۴۳-۱.۹۱ And their body mass index ۲۸.۲۱-۲.۰۵. The subjects were randomly divided into two groups: ۱: aerobic exercise, ۲: guarana supplement + aerobic exercise. Aerobic exercise started with an intensity of ۶۵% of maximum heart rate and then after every two weeks ۵% was added to the exercise pressure and the whole course was for ۸ weeks and ۳ sessions per week (۲۴ sessions in total). The training duration of the subjects in each session was about ۶۰ minutes and the exercises consisted of three parts: warm-up (۱۰ minutes), aerobic exercise (۴۰ minutes) and cooling (۱۰ minutes). ۴۸ hours before and after the last training session and while they were fasting for eight hours, blood samples were taken from the subjects in the sitting position and fasting at a rate of five cc from the brachial vein. The guarana supplement group took the dose (۳۰۰ mg guarana supplement capsule) on the training days half an hour before the start of the protocol and the placebo group (capsule containing ۸۹% fructose and ۱۱% maltodextrin). Normal data were analyzed using independent t-test and for abnormal data from U-Mann-Whitney test with a confidence level of P <۰.۰۵. Results: The results showed that serum adiponectin, HDL and insulin resistance levels in the Guarna supplement group + exercise compared to the placebo group + exercise increased significantly (p = ۰.۰۳۸, (p = ۰.۰۲), (= ۰.۰۱). p) and fat percentage showed a significant decrease in die value (p = ۰.۰۰۱). But no significant change was seen in insulin, TG, CHOL and LDL factors (p = ۰.۱۵), ), (P = ۰.۶۹۰), (p = ۰.۲۹۷). Conclusion: It seems that ۸ weeks of aerobic exercise and guarana supplementation have a positive effect on obesity markers in inactive women.
