Efectos de un programa de ejercicio aeróbico en mujeres pre y postmenopáusicasperfil esteroideo y elementos traza

Résumé

Women experience a series of hormonal changes with menopause, which adversely affect their health. This coupled with rising life expectancy, make women live nearly a third of their life in postmenopausal state, with an increased risk of many diseases. Physical exercise has been shown as a useful and effective tool for improving health in postmenopausal women. We intend to analyze the effects of an exercise program, based on the practice of aerobic dance, on the steroid profile, in plasma and urine, and the urinary excretion of a group of trace elements, in groups of pre and postmenopausal women. After the physical exercise program, there has been a significant decrease in urinary levels of estrogen in postmenopausal women, which has been associated with a decreased risk of breast cancer. Furthermore, the proposed physical exercise has caused a significant decrease in urinary progesterone levels in both groups, with increase in plasma levels of this steroid. This greater retention by the body would be positive for women´s health because progesterone has beneficial effects by reducing the risk of osteoporosis, neurodegenerative diseases and breast cancer. As far as toxic elements are concerned, there are higher urinary levels in premenopausal women, and it has been observed that exercise tends to reduce urinary levels in both groups. Assumed that due to the toxicity, lower urinary levels reflect lower circulating levels, implying reduced risk of certain diseases such as Alzheimer in the case of aluminum and mercury or hypertension in the case of lead.
