Aerobic exercise significantly decreased the chemical imbalances that can lead to heart disease and stroke in postmenopausal women according to a study in the spring issue of the Journal of Women and Aging.
Estrogen is known to reduce the chemical imbalances that can lead to cardiovascular diseases such as coronary heart disease and stroke in postmenopausal women. However, recent studies have reported detrimental effects of long-term use of hormone replacement therapy (HRT) or estrogen replacement therapy, including an increased risk of stroke, heart attack and breast cancer. Faced with these potential consequences, more women are turning to exercise as a natural way to combat postmenopausal effects.
The study found that HRT users and non-HRT users benefited equally from the exercise.
Given the controversy with HRT, postmenopausal women can now use aerobic exercise training to lower chemical stress levels, thus reducing another risk factor for chronic disease, said Michael D. Brown, Ph.D., a co-author and associate professor of kinesiology at Temple Universitys College of Health Professions.
The chemical imbalance or stress called oxidative stress occurs when oxidants, harmful chemicals that damage tissue and cells, outnumber antioxidants in the body. Antioxidants protect cells and tissues against oxidants. Postmenopausal women have higher levels of oxidative stress.
Regular exercise of moderate intensity appears to reduce oxidative stress through an adaptive process that increases antioxidant activity.
Regardless of your hormone replacement therapy status, regular physical activity is a good way to not only decrease postmenopausal symptoms, but also to reduce the risk of cardiovascular disease, the leading cause of death of American women, said study co-author Nicola Fenty-Stewart, Ph.D., also with Temples College of Health Professions.
The similar response of the two groups suggests that aerob
