A Study of How the Regulation of Resting Blood Pressure is Altered in Menopausal Women

Overview

About this study

The purpose of this study is to investigate whether the autonomic support of blood pressure alters after menopause in women, the importance of female sex hormones in blood pressure control, and the potential for exercise training to provide a therapeutic pathway that might limit increases in blood pressure in this population.
