About

The study will evaluate the variability of blood pressure in postmenopausal and hypertensive women after only one session and after training of ten weeks of combined physical exercises (aerobic and resisted).

Full description

Before starting the training program, all the volunteers will sign the Free and Informed Consent Form (TCLE) and must present a medical certificate releasing the participation. In addition, the volunteers will respond to an anamnesis questionnaire and will undergo an anthropometric evaluation before the experimental sessions. The physical exercise program will be held three times a week for 10 weeks, containing aerobic exercise (exercise treadmill) and resistance exercises (bodybuilding). Initially, a familiarization of the ergometers used will be performed, followed by a session to evaluate the intensity of resistance exercise through a maximal repetition test (1RM), and a session to evaluate aerobic fitness through an incremental treadmill test.

Before starting the training, volunteers will perform a single exercise session, following the same exercise protocol. All the volunteers will be submitted to the evaluation of the blood pressure during 24 hours through the measurement of ambulatory blood pressure (ABPM) in three moments:

• PR: pre-training rest - the volunteers will arrive at the laboratory, will be in rest for 15 minutes and after that they will place the ABPM, without having done any exercise.
• PE: post exercise - upon arriving at the laboratory, the volunteers will be submitted to a single combined exercise session, will have a maximum interval of 20 minutes for the bath and will place the MAP device.
• CR: rest after chronic training - after the end of the 10 weeks of training, the volunteers will be submitted to ABPM, again at rest, with a maximum interval of 72 hours, between the end of the training and the placement of the device.
