Brief Summary:
Two-center randomized, parallel, controlled trial which will compare a pragmatic combined training program with a health education program in 184 older adults with hypertension. This study will last 12 weeks with assessments conducted at baseline, previously to the group allocation, and after interventions. There is a set of secondary outcomes which show clinical importance to the elderly population and are possibly influenced by the tested intervention.

Detailed Description:
The present protocol describes a randomized controlled trial that aims to evaluate blood pressure effects of a pragmatic combined training program, with low equipment needs, in comparison with a health education program. The sample is composed by 184 older adults, divided in two implementation centers. Randomization ratio will be 1:1 and interventions will last 12 weeks, with three weekly sessions for the exercise arm and one to the health education arm. In order to analyze the effects of interventions in a comprehensive way, a range of variables related to ambulatory blood pressure (primary outcome), physical fitness, vascular and autonomous function, together with emotional and cognitive aspects will be evaluated in a pre-post fashion. The study's hypothesis, as well as the sample size calculation and analysis plan, is based on a superiority expectation for the exercise program in comparison with the health education program, especially for the blood pressure control, functional capacity and quality of life. The present study was designed and will be conducted by a multidisciplinary staff and follows ethical and methodological recommendations for clinical trials. It is expected that this multicenter randomized trial will provide scientific evidences with a high applicability to the non-pharmacological management of hypertension in the elderly.

Arm Intervention/treatment
Active Comparator: Health education
Patients will receive weekly lectures on hypertension related topics during 12 weeks.
Behavioral: Health education
Weekly group lectures (1h each) giving information on patient's best practices to manage hypertension.

Experimental: Combined training
Patients will complete 12 weeks of combined training (aerobic + strength exercise, 3x/week) in a pragmatic setup. In order to make the interventions more similar, contents of the health education arm will also be discussed with patients receiving this intervention.
Behavioral: Combined training
Combined training (aerobic and strength exercises), in moderate intensities (perceived exertion controlled) performed 3x/week (1h) duration with a education component (10') based on the contents of the health intervention.




Primary Outcome Measures :
  1. Ambulatory Blood Pressure [ Time Frame: Change from baseline 24-hour systolic blood pressure at 12 weeks ]
    24h ambulatory blood pressure measured through automatic oscillometric device


Secondary Outcome Measures :
  1. Walking distance [ Time Frame: Change from baseline walking distance at 12 weeks ]
    Longest distance walked as assessed by the six-minute walk test

  2. Lower limbs functional capacity [ Time Frame: Change from baseline SPPB score at 12 weeks ]
    By using the Short Physical Performance Battery (SPPB), lower-limb mobility will be assess in the following sequence: static standing balance, walking speed and indirect muscle strength

  3. Cardiorespiratory fitness [ Time Frame: Change from baseline VO2peak at 12 weeks ]
    Oxygen consumption at peak (VO2peak) as assessed by maximal cardiopulmonary exercise testing

  4. Geriatric Depression Symptoms [ Time Frame: Change from baseline GDS-15 score at 12 weeks ]
    15-item depression symptoms scale (GDS-15)

  5. Quality of life (QoL) [ Time Frame: Change from baseline QoL score at 12 weeks ]
    World Health Organization Quality of Life questionnaire

  6. Autonomic function [ Time Frame: Change from baseline beat-to-beat blood pressure variability at 12 weeks ]
    Basal and during Stroop Color-Word Conflict Test beat-to-beat blood pressure variability

  7. Endothelial function, early adaptation [ Time Frame: Change from baseline FMD at 6 weeks ]
    Flow-mediated dilatation (FMD) assessed through high resolution ultrasonography

  8. Endothelial function [ Time Frame: Change from baseline FMD at 12 weeks ]
    Flow-mediated dilatation (FMD) assessed through high resolution ultrasonography
