High-Intensity Interval Versus Moderate-Intensity Continuous Water Based Exercise in Hypertensive Older Individuals

Condition(s) studied

Investigational drug(s) / intervention(s)

High Intensity Interval Exercise in Heated Water-Based: High intensity interval exercise will perform at controlled heated water-base (30 e 32 ºC). Subject will be submerged at the xiphoid process level. The session will consist in 4 min walking (warm-up) at 9 level of rate perceived exertion (RPE) scale, followed by 21 min of HIIE, alternating 1 min of jogging/running at 15-17 (hard-very hard) level with 2 min of walking at 9-11 (very light-fairly light) level of RPE.

Continuous Moderate Exercise in Heated Water-Based: Continuous moderate exercise will perform at controlled heated water-base (30 e 32 ºC). Subject will be submerged at the xiphoid process level. The session will consist in 4 min walking (warm-up) at 9 level (light) of RPE, followed by 26 min of MICE, walking at 11-13 (fairly light)level of RPE.

Control Group: CON session will perform at controlled heated water-base (30 e 32 ºC). Subject will be seated in a chair and submerged at the until xiphoid process level for 30 min.

Study summary

This study will investigate the acute and chronic effects in hemodynamic and autonomic variables to high-intensity interval versus moderate-intensity continuous heated water-based exercise in older individuals with hypertension.

Eligibility

Primary outcome measure(s)

• Change from baseline Blood Pressure (Systolic and Diastolic) following 12 weeks of exercise. — 12 weeks
  Blood pressure will be assessed in resting (Omron HEM 7200®, Omron Healthcare Inc, Dalian, China) at the day of the sessions and using a 24 hour ambulatory blood pressure monitoring (Cardio-Mapa ®, Cardios System Ltda, Sao Paulo, Brazil), at the baseline and after 12 weeks of exercise.
