The effect of eight weeks of resistance and aerobic training on the levels of IGFBP 3, IGF1, and BMI in obese women of Ahvaz city

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 .

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.

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).

According to the results of this research, both resistance and aerobic training methods can be used to reduce weight, BMI, IGFBP3 and IGF1.
