Overview
Brief Summary
This study will compare different exercise training protocols on health parameters of postmenopausal women. The hypothesis is that short duration high intensity interval training will promote different effects of long duration moderate intensity training.
Detailed Description
Exercise load control still not a consensus as to the most effective strategy for improving health parameters in postmenopausal women. In this way, the volunteers will perform anthropometric and body composition assessments, climacteric symptoms and sleep quality evaluations, blood pressure reactivity, resting blood pressure and heart rate and ambulatorial blood pressure monitoring, before and after 12 weeks of training.

Eligibility Criteria
Inclusion Criteria
- •being postmenopausal (amenorrhea of at least 12 months and \[FSH\]\> 40 mlU/ml); be controlled hypertension; not to undergo drug treatment with β-blockers; not make use of sex hormone therapies; do not present physical problems or cardiovascular complications that prevent the performance of physical exercises; present attestation of a cardiologist proving that they are able to perform physical exercises.
Exclusion Criteria
- •Do not attend the collection site on the day and time programmed more than once in the acute phase of the study; missing more than 2 consecutive sessions or 6 alternates in the chronic phase of the study; unable to perform the proposed training protocols; change in drug therapy during the intervention.
Outcomes
Primary Outcomes
Changes in Ambulatorial Blood Pressure
Time Frame: Before and within 72 hours after 12 weeks of exercise training/control
All volunteers were submitted to a 24-hour Blood Pressure (BP) assessment by Ambulatorial Blood Pressure Monitoring (ABPM) before and after 10 weeks of combined exercise training, with a minimum of 48 hours after the last training session. A device was used associated with a diary of examination to self-report of activities of daily living (sleep, work, food) or any event that could interfere abnormally with BP or device measurements. The device was always placed 7am and the measurements were made every 15 minutes from 7h to 23h and every 30 minutes from 23h to 7h. The monitoring was considered valid when it happened for a period of 24 hours. The following results were evaluated: systolic blood pressure; diastolic blood pressure and mean blood pressure in awake, sleep and 24-hour periods, and shall be expressed in mmHg.
Changes in Resting Blood Pressure
Time Frame: Before and within 72 hours after 12 weeks of exercise training/control
Before the use ABPM during daily activities, resting blood pressure were measured using the same equipment after 15 min of rest in siting position. The following results were evaluated: systolic blood pressure; diastolic blood pressure and mean blood pressure, they shall be expressed in mmHg.
