To investigate the independent and additive effects of selective short aerobic moderate intensity exercise and soya intake on serum 17β-estradiol and obesity in obese postmenopausal women, this quasi-experimental study conducted in 2006 on women of Uremia, Iran. So 56 obese postmenopausal women were selected and randomly divided into four groups of 14 subjects as follow: exercise-soya, exercise, soya, and control group. Pre- and post-protocol blood samples were collected and the rate of 17β-estradiol concentration was measured. Exercise training within the range of 60-70% maximum heart rate (MHR) was performed for 60 minutes, 3 sessions per week. The subjects of soya group and exercise-soya group had a 100 gram soya nut intake daily for 10 weeks. After The training course, blood samples were taken from the subjects. The collected data was analyzed using Two-way ANOVA and paired t-test. Having soya along with exercise had significant impact on reduction of 17β-estradiol means (p<0.05). Body mass index, waist to hip ratio and weight decreased significantly in exercise-soya group after 10 weeks (p<0.05). Based on the findings of this study, aerobic moderate intensity exercise along with soya intake, decrease obesity and serum 17β-estradiol in obese postmenopausal women.
