Effect of Isometric and Aerobic Physical Exercise on Blood Pressure Levels in Hypertensive Elderly People

Group control The control session will consist of keeping the volunteer sitting in a calm, air-conditioned environment for 40 minutes.

The intervention with isometric exercise for the lower limbs, the volunteers will start in a vertical position, with shoulders and hips in contact with the wall, feet parallel and shoulder-width apart and hands at the sides of the body. Then (second phase), the volunteers, maintaining contact with the wall, squatted and advanced their feet in the desired position until the knee joint angle reached the previously determined value. The third phase referred directly to the isometric effort of the isometric exercise session. For the isometric wall squat exercise session, volunteers will be asked to perform 4 repetitions of 2 minutes, with a 2-minute rest interval in a seated position for adequate rest between each repetition.

Volunteers will perform 50 minutes of horizontal exercise cycling (brand: pro-user), continuously and at moderate intensity (50% to 60% of HR reserve).
