The aim of this study was to investigate the effect of eight weeks resistance training on leptin levels changes and insulin resistance in obese females. Twenty inactive and obese female students (mean age 23.5± 1.56, the average height of 160.1± 4.4 and the average BMI 31.17 ± 1.51) participated in this study. Subjects randomly were divided into two groups: controls 10 and experimental 10. Subjects in experimental group were performed 8 weeks resistance training program (chest press, leg press, lat pull down, leg curl, bicep curl, leg extension) with 60 - 70 percent of 1RM. Data were analyzed using by analysis of covariance (ANCOVA) and independent t-test. (P ≤ 0.05). The results of this study showed that, there was no significance differences in leptin, insulin and glucose levels and insulin resistance between control and experimental groups (P＞ 0.05), after 8 weeks of resistance training. However, there was a significant difference between two groups (P ＜0.05) in body weight, body mass index and percent body fat. After eight weeks resistance training, body weight, BMI, WHR and percent body fat in the experimental group were decreased. Our study showed that 8 weeks resistance training have a positive effect on reducing body weight, BMI, WHR and percent body fat but could not decrease leptin, insulin and glucose levels and insulin resistance.
