Objective: The purpose of this study was to examine the effect of 12 weeks of moderate intensity aerobic exercise on echocardiographic and cardiorespiratory fitness (CRF) parameters, lymphocyte estrogen receptor alpha (ERα) gene expression and sex hormones (17β-estradiol and progesterone) in overweight/obese postmenopausal women (OPMW).

Methods: Twenty-seven sedentary OPMW aged 45 to 65 years old were randomly assigned to exercise (EX, n = 14) and control (C, n = 13) groups. The EX group performed warm up-walking/jogging moderate intensity aerobic exercise program- recovery (60 min/day, 3 days/week at 70 % of maximal heart rate reserve for 12 weeks) while the C group participated in no intervention and maintained their daily physical activity level, sedentary normal lifestyle and dietary habits during 12-week.
