Abstract

Background and Objectives Menopause is associated with cardiovascular
complications. The present study aimed to determine the effect of eight weeks of
aerobic exercise and soybean consumption on cardiovascular function in
postmenopausal women.
Subjects and Methods In this semi-experimental research, 60 postmenopausal
women living in Andimshek City, Khuzestan province, Iran, were selected by
purposeful sampling and then randomly divided into four groups: 1) soy (n=15), 2)
exercise (n=15), 3) combined (exercise+soy, n=15), and 4) control (n=15 people). The
exercise intervention consisted of eight weeks of exercises, three sessions per week
with an intensity of 50-70% of heart rate reserve. Soy consumption was 80 g of
soybeans daily. Paired sample t-tests and covariance analysis were used for statistical
analysis, and the significance level was considered p ≥ 0.05.
Results A significant decrease in systolic blood pressure, diastolic blood pressure, and
resting heart rate was observed in the aerobic and combined exercise groups
compared to the control group (P<0.01). A significant decrease in systolic blood
pressure was also observed in the soy group compared to the control group (P<0.001).
Moreover, the decrease in resting heart rate was significantly higher in the aerobic and
combined exercise groups than in the soy group (P<0.001).
Conclusion According to the results, it can be said that aerobic exercises and the
consumption of nuts have positive effects on improving cardiovascular function in
postmenopausal women, and the use of both boosts effectiveness in cardiovascular
protection.
