Brief summary
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.
Detailed description
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.
Interventions
OTHERTraditional Pilates group
The participants will perform only exercises based on the traditional Pilates method, 2 times a week, for 50 minutes, for 16 weeks.
OTHERModified Pilates group
The participants will perform exercises based on the Pilates method alternated with active rest periods on treadmill ergometer, 2 times a week, for 50 minutes, for 16 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ambulatory blood pressure | Change from Baseline systolic and diastolic Blood Pressure at 16 weeks | Systolic and diastolic blood pressure will be measured by 24-hour Ambulatorial Monitoring Blood Pressure, before and after trial period. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical heart rate | Change from Baseline clinical heart rate at 16 weeks | Clinical assessment of heart rate will be measured by a heart rate monitor after 10 minutes of rest, before and after trial period. |
| Autonomic heart rate modulation | Change from Baseline autonomic heart rate modulation at 16 weeks | Autonomic heart rate modulation will be assessed by the heart rate variability method using a heart rate monitor, before and after trial period. |
| Ventilatory threshold measured by the cardiopulmonary exercise test | Change from baseline and at 16 weeks | 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. |
| Analysis of the quality of life | Change from Baseline quality of life at 16 weeks | 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. |
| Flexibility | Change from Baseline flexibility at 16 weeks | Flexibility will be analyzed by bank of wells test, before and after trial period. |
| Strength | Change from Baseline strength at 16 weeks | Strength will be analyzed by hydraulic handgrip dynamometer, before and after trial period. |
| Clinical blood pressure | Change from Baseline systolic and diastolic Blood Pressure at 16 weeks | 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. |
| Speed to lift from a layered position | Change from Baseline speed at 16 weeks | Speed to lift from a layered position will be evaluated by a stopwatch, before and after trial period |
| Speed to put on and tie his shoes | Change from Baseline speed at 16 weeks | Speed to put on and tie his shoes will be evaluated by a stopwatch, before and after trial period. |
| Body weight | Change from Baseline body weight at 16 weeks | Body weight will be measured using a digital scale, before and after trial period. |
| Height | Change from Baseline at 16 weeks | Height will be measured using a stadiometer. |
| Body Mass Index | Change from Baseline body mass index at 16 weeks | Will be analyzed as weight divided by height squared. |
| Circumference measurements | Change from Baseline circumference measurements at 16 weeks | Will be analyzed the circumference of hip, waist, neck, abdomen, before and after trial period. |
| Speed to lift from a sitting position | Change from Baseline speed at16 weeks | Speed to lift from a sitting position will be evaluated by a stopwatch, before and after trial period. |
