Effects of Training Based on the Pilates Method on the Blood Pressure of Hypertensive Women

João Luiz Q. Durigan60 enrolled

Overview

The main objective of this study is to evaluate and compare the effect of the Pilates method associated with aerobic exercise and the traditional Pilates method on the blood pressure of hypertensive medicated women. In addition, we aim to analyze and compare the chronic effects of training on cardiac autonomic modulation, on cardiorespiratory fitness, functionality and quality of life.

Subjects will be allocated randomly in three groups: (1) Traditional Pilates group, which will perform only exercises based on the traditional Pilates method, (2) Modified Pilates group, which will perform exercises based on the Pilates method alternated with active rest periods on treadmill ergometer, (3) Control group: will not perform any physical exercise during the trial period. The sessions will be performed two times a week, during 16 weeks. Subjects will be evaluated before and after 16 weeks of intervention.

Outcomes

Primary Outcomes

Ambulatory blood pressure

Systolic and diastolic blood pressure will be measured by 24-hour Ambulatorial Monitoring Blood Pressure, before and after trial period.

Time frame: Change from Baseline systolic and diastolic Blood Pressure at 16 weeks

Secondary Outcomes

Clinical blood pressure

Clinical assessment of systolic and diastolic blood pressure will be measured by an automatic arm blood pressure monitor after 10 minutes of rest, before and after trial period.

Time frame: Change from Baseline systolic and diastolic Blood Pressure at 16 weeks

Clinical heart rate

Clinical assessment of heart rate will be measured by a heart rate monitor after 10 minutes of rest, before and after trial period.

Time frame: Change from Baseline clinical heart rate at 16 weeks

Autonomic heart rate modulation

Autonomic heart rate modulation will be assessed by the heart rate variability method using a heart rate monitor, before and after trial period.

Time frame: Change from Baseline autonomic heart rate modulation at 16 weeks

Ventilatory threshold measured by the cardiopulmonary exercise test

The ventilatory threshold will be measured by the cardiopulmonary exercise test. An ergospirometric exercise test will be performed, consisting of increasing loads, with no pauses between the stages until exhaustion of the volunteer. The examination will be performed in a treadmill with ergospirometric and electrocardiographic analysis.

Time frame: Change from baseline and at 16 weeks

Analysis of the quality of life

Quality of life will be analyzed by means of the questionnaire World Health Organization Quality Of Life/Bref (WHOQOL/bref). The questionnaire has twenty-six questions that involve different aspects of daily life and deal with four domains of quality of life: physical, psychological, environmental and social relations. The response is represented by scores ranging from one to five, with the worst score being one and the best score being five. The results of the domains have values between zero and one hundred, with the worst being the closest to zero and the best the closest to one hundred, thus, a value equal to 50 for a given domain can be considered median for that domain.
