Abstract

Population aging is an unprecedented worldwide reality, which results in a change of epidemiological profile and increased prevalence of age-related non-communicable chronic diseases (NCDs). Among age-related NCDs, systemic arterial hypertension (HPT) is the leading cause of mortality and disability worldwide, and has increased prevalence, morbidity and mortality with advancing age. Increase in physical activity level through regular physical exercise is one of the main global goals for the prevention and treatment of HPT and others CNCDs. Among the different exercise types and intensities, continuous moderate-intensity heated water-based exercise (MOD-HEx) and high intensity interval (HIT) dryland exercise showed superior benefits for reducing blood pressure (BP) and improving variables involved in the pathophysiology of hypertension, when compared to continuous moderate-intensity dryland exercise. However, little is known about the effect of HIT heated water-based exercise (HIT-HEx) on BP and other hemodynamic variables involved in the pathophysiology of hypertension in older hypertensive individuals. PURPOSE: To evaluate the hemodynamic and autonomic response to a HIT-HEx versus MOD-HEx session in older individuals with hypertension. METHODS: 15 older sedentary individuals (age > 60 yr) with hypertension, of both sexes and under antihypertensive drug treatment, will be assigned to perform HIT-HEx, MOD-HEx and no exercise control (CON) sessions in random order. Resting BP and heart rate, arterial stiffness, endothelial reactivity and heart rate variability (HRV) will be assessed before, immediately after and 45 minutes after each intervention. Ambulatory BP and HRV will also be analyzed for 24 hours after the end of each intervention. HIT-HEx and MOD-HEx sessions will be performed in a heated-water swimming pool (29-32oC), with water up to xiphoid process. HIT-HEx session will have a 25-min duration, with 4 min of warm-up, followed by 21 min alternating 1 min of high-intensity exercise [walking, jogging or running (depending on individual's fitness) with intensity between 15 ("tiring") and 17 ("very tiring") on the 6 to 20 rating of perceived exertion (RPE) scale] with 2 min of active recovery [walking with intensity between 9 ("easy") and "11 ("relatively easy") on the RPE scale]. MOD-HEx will have a 30-min duration, with 4 min of warm-up, followed by 26 min of moderate intensity exercise (walking with intensity between 11 ("relatively easy") and 13 ("slightly tiring") on the RPE scale]. CON session will be a 30 min rest at sitting position.
