Effects of Different Exercises Interventions in Post-menopausal Women
January 7, 2021 updated by: Igor Moraes Mariano, Federal University of Uberlandia
Acute and Chronic Health Effects of Different Exercises Interventions in Post-menopausal Women: a Clinical, Controlled and Randomized Study
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Control
Hypertensive post menopausal women, who will do the evaluations before the beginning and after 12 weeks without perform exercise training.
|
Consist of performing no exercise training.
|
Experimental: Alternative training
Hypertensive post menopausal women, who will do the evaluations before the beginning and after 12 weeks of high intensity interval training.
|
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.

|
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).

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
|
Before and within 72 hours after 12 weeks of exercise training/control
|
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.
|
Before and within 72 hours after 12 weeks of exercise training/control

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in Heart Rate Variability
Time Frame: Before and within 72 hours after 12 weeks of exercise training/control
|
Heart Rate (HR) was recorded using a heart rate monitor in a beat-by-beat basis.
HR was registered in a seat position for 20 min of rest.
Prior to the HR Variability (HRV) analysis, the RR intervals (RRi) were visually inspected and filtered using a moving average filter.
The HRV was analyzed in both time-, frequency- and nonlinear-domain.
Being that for frequency-domain analysis, firstly the RRi series were interpolated at 4 Hz and then the signal linear trend component removal was performed using the smooth priors approach.
|
Before and within 72 hours after 12 weeks of exercise training/control
|
Changes in Ambulatorial Blood Pressure Variability
Time Frame: Before and within 72 hours after 12 weeks of exercise training/control
|
Based on Ambulatorial Blood Pressure data, were calculated Blood Pressure Variability by: 24-hour standard deviation weighted by the time interval between consecutive readings; the mean diurnal and nocturnal deviations weighted for the duration of the daytime and nighttime interval; the average real variability weighted for the time interval between consecutive readings; the ambulatory arterial stiffness index calculated by the slope of the trend curve of the dispersion of pressure data; the morning surge that represents the dynamic daytime variation in morning pressure that tends to increase, being assessed from the point of least pressure during sleep in relation to the first two hours after waking; and nocturnal dipping, that represents the average percentage drop of sleep pressure in relation to wakefulness, and individuals with falls of 10% or more are considered dippers and below that are considered nom-dippers.
|
Before and within 72 hours after 12 weeks of exercise training/control
|
Changes in Blood pressure reactivity
Time Frame: Before and within 72 hours after 12 weeks of exercise training/control
|
To evaluate blood pressure reactivity under mental stress, it will be used the 3 minutes Stroop protocol of words and colors.
The test consists of a video on a computer screen facing the volunteer that changes the image every 2 seconds.
The volunteer should then speak as quickly as possible the color of the letters present on the screen, being that in each image there is dissonance between the background color, the color of the letters and the word formed (which is always the name of another color ).
At the end of the test, the volunteer demonstrates on a scale her difficulty in the test, according to the following classification: 0 = not stressful; 1 = slightly stressful; 3 = very stressful; and 4 = extremely stressful.
Each minute of the test the blood pressure will be measured by auscultatory method, with stethoscope and mercury column, and the following results were evaluated: systolic blood pressure and diastolic blood pressure.
