Effects of combined selective aerobic moderate intensity exercises and soya intake on 17β- estradiol (biomarker of breast cancer) and obesity of obese postmenopausal women

摘要

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-estradio l 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
