Abstract: Increases in blood pressure (BP) are directly related to increases in body mass and obesity related hypertension is associated with pronounced activity of the renin-angiotensin-aldosterone system (RAAS) and increased pulse wave velocity (PWV). The purpose of this study was to assess RAAS activity and PWV before and after 4 weeks of aerobic exercise in an obese, hypertensive population, who were also unmedicated. Seven men and three women underwent 4 weeks of moderate intensity aerobic training (30 min., 3x/wk, 65% VO2 peak). Body mass (BMI), BP, and blood markers were taken at baseline, post 4 week control period, and post 4 weeks of exercise. No significant differences were seen in descriptive characteristics following the control period; however, there were significant declines in aldosterone and PWV following training. These data show that 4 weeks of moderate intensity aerobic exercise decreases central PWV and may be linked with decreases in ALDO in this population.
