Abstract: Obesity-related hypertension is associated with increased activity of the renin-angiotensin-aldosterone system (RAAS), increasing arterial stiffness. Aerobic exercise decreases pulse wave velocity (PWV), therefore a treatment option for hypertension and obesity. Assess RAAS activity and PWV before and after 4 weeks of aerobic training in unmedicated, pre-to-stage-1 hypertensives. Ten obese subjects (52±3.2 years, body mass index ¼ 33.5±1.4) performed 30 min of aerobic exercise on a treadmill 3 days per week at 65%of peak oxygen consumption (VO2peak). Descriptive characteristics, systolic and diastolic blood pressure (SBP and DBP), PWV, and a blood draw was performed at baseline, following the 4-week control and training interventions. No differences in descriptive characteristics during the control period were observed, however, a signi?cant decrease in plasma aldosterone (ALDO) (255.4±75 to 215.8±66 pg ml 1, P ¼ 0.001), SBP (140±12 to 136±10.4 mm Hg; P ¼ 0.02), DBP (89±4.2 to 85±6.3 mm Hg; P ¼ 0.03) and central PWV (11.2±0.6 to 9.8±0.8 m s 1; P ¼ 0.04) was shown pre-to-post exercise training. Four weeks of moderate-intensity aerobic training in obese, hypertensives decreases plasma ALDO independently of body weight and is signi?cantly correlated to decreases in PWV reductions.
