Study Summary
Older women have an exaggerated increase in blood pressure during exercise. However, the reasons for this are unclear. It is important to investigate this phenomenon because a greater blood pressure response to exercise has been associated with an increased risk of stroke and mortality in otherwise healthy individuals. A unique aspect of aging in women is the profound change in hormone levels (i.e. estrogen and progesterone) associated with menopause. The influence of changes in estrogen and progesterone levels on the cardiovascular responses to exercise is poorly understood. However, it has been suggested that these hormones might change the responsiveness of the cardiovascular system. Possible mechanisms that could account for these changes are the arterial baroreflex and feedback from the exercising muscle (known as the exercise pressor reflex), both of which are known to powerfully modulate blood pressure during exercise. However, to date, few human studies have thoroughly examined the influence of changes in hormone levels on baroreflex function during exercise or the exercise pressor reflex in older women. As such, the purpose of this research project is to assess baroreflex function and the exercise pressor reflex in older women after transdermal estrogen and placebo.
