Introduction and purpose: The purpose of this research is to investigate the effect of exercise (resistance-aerobic) on the levels of IGFBP3, IGF1, and BMI in obese wome .Materials and methods: For this purpose, 24 inactive obese women aged 25 to 37 years with a BMI of 30 to 35 kg/m2 were randomly divided into two groups of 12 people, training and control. The selected exercise included resistance training with weights and a special bodybuilding machine with an intensity of 67 to 80% of the maximum strength and aerobic exercise with a stationary bike and an intensity of 60 to 85% of the maximum heart rate, for 8 weeks and 3 days a week. Body composition measurements were taken 24 hours before and 24 hours after exercise. For statistical analysis in the findings section, one-way analysis of covariance test was used to examine inter-group changes. Findings: The results of this study showed that after eight weeks of resistance and aerobic training, a significant decrease in the BMI of subjects in the training group was observed compared to the control group (P<0.001). Also, the results of analysis of covariance showed that after eight weeks of selected training (resistance-aerobic) the two indexes of IGFBP3 and IGF1 in the training group decreased significantly compared to the control group (P<0.001 and P<0.006, respectively). Conclusion: According to the results of this research, both resistance and aerobic training methods can be used to reduce weight, BMI, IGFBP3 and IGF1.
