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.

Conditions

Hypertension; Menopause

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Control

Hypertensive post menopausal women, who will do the evaluations before the beginning and after 12 weeks without perform exercise training.

Group Type: PLACEBO_COMPARATOR

Control

Intervention Type: OTHER

Consist of performing no exercise training.

Alternative training

Hypertensive post menopausal women, who will do the evaluations before the beginning and after 12 weeks of high intensity interval training.

Group Type: EXPERIMENTAL

High intensity interval training

Intervention Type: OTHER

Consists of 60 seconds sets of high-intensity exercises, characterized by heart rate\> 85% of maximal heart rate (HRmax), obtained through the formula (220-age), or by the Rated Perceived Exertion between 7 and 8 on the Borg scale, which ranges from 0 to 10. Of the 60 seconds of high intensity exercise, 30 seconds will be to get up and down a 16 cm step and 30 seconds of squats, with knee flexion greater than 90º, both at the highest possible speed. The recovery between sets is light walk for 60 seconds. If the volunteers do not reach the proposed intensity zone, they will be instructed to increase the number of squats and step ascents and descents.

Conventional training

Hypertensive post menopausal women, who will do the evaluations before the beginning and after 12 weeks of moderate intensity continuous training

Group Type: EXPERIMENTAL

Moderate intensity continuous training

Intervention Type: OTHER

Consist of performing a 30 minute walk at 50% of reserve heart rate (HRR), calculated by (HRmax - HRmax) x% + HRmax. HRmax being obtained by means of the formula (220 - age).
