- Brief Summary
Introduction: According to the World Health Organization, Hypertension kills 9.4 million people every year in the world, and in Brazil about 30 million Brazilians suffer from SAH, and 12 million do not know they have the disease. Objective: To analyze cardiac autonomic modulation in elderly patients with SAH during aerobic exercise. Method: 60 elderly hypertensive individuals will be analyzed using a heart rate monitor (S800CX, Polar). Participants will be kept in a supine position and at rest for 10 minutes for baseline HRV uptake. With the collection of heart rate (HR) at rest and maximum heart rate (HRmax) evaluated at 50 and 70%. After the rest period, the elderly will walk on an RT250pro treadmill for aerobic exercise divided into: 5 minutes of warm-up and 20 minutes of exercise, reaching 70% of HRmax. At the beginning and every 5 minutes of exercise, systolic (SBP) and diastolic (DBP) and heart rate (HR) measurements will be measured. Immediately after the 25 minutes of training, the patient will be advised to lie down for 30 minutes, where the polar trainer will continue to record heart rate variability (HRV). The recovery period will be defined immediately after performing the aerobic training. After filtering the signal, it will be divided into six moments: the “M1” period of 10 minutes of rest; "M2" to 20 minutes of the intermediate exercise period, and "M3" which will consist of the recovery period (post-exercise) of the patient, but the HRV in this recovery period for analysis will be divided into three new moments. Moment called "Recovery 1" - (R1) in the first five minutes of recovery, the second measure ("Recovery 2" - R2), comprising between the tenth minute to the fifteenth minute and the third recovery time (R3) of the twenty-fifth to thirty minutes.
