简要总结
At least 36 volunteers with a diagnosis of hypertension in the Department of Cardiology of Dokuz Eylul University and who meet the criteria for follow-up and inclusion will participate in the study. The aim of this study is to compare the acute effects on atherosclerosis, heart rate variability, blood pressure, perceived exertion, energy expenditure, and muscle strength of using different frequencies in whole body vibration training (WBVT) in hypertensive patients. Individuals will perform; static squat, dynamic toe raise, static abduction and dynamic squat exercises in both hips on a vibrating platform. In each session, a different frequency (0,25 and 40 Hz) will be applied. 0 Hz, 25 Hz and 40 Hz sessions will be randomized to last 15 minutes. Demographic and clinical information of the participants will be questioned.Before and after the sessions; hemodynamic and pulmonary responses, vascular responses, heart rate variability and quadriceps femoris muscle strength will be measured. In addition, energy expenditure will be recorded during the sessions.
详细描述
Hypertension is one of the most common chronic diseases and it is an important global public health problem. In cardiac rehabilitation programs, aerobic exercise, resistance exercise and a combination of aerobic and resistance exercise are recommended to reduce cardiovascular risk. Whole body vibration training has also started to be used among new applications in the cardiac rehabilitation programs. Whole body vibration training has been reported as an effective and safe approach for both healthy and cardiovascular diseased women and men. It has been shown to be beneficial in improving atherosclerosis and blood pressure in hypertensive patients. In whole body vibration training, frequencies of 20-40 Hz are generally used for hypertensive elderly patients. However, the optimal frequency in this population has not been fully determined. For these reasons, the aim of the study is to compare the acute effects of using different frequencies in whole body vibration training in hypertensive patients.
Whole body vibration intervention will be performed with the Power Plate Pro 5 device (Power Plate International, London, UK). Whole body vibration training will be performed at three different frequencies (0, 25 and 40 Hz). Each patient will complete the training in these 3 frequencies in random order and on different days. Before and after the sessions; hemodynamic and pulmonary responses, vascular responses, heart rate variability and quadriceps femoris muscle strength will be measured. In addition, energy expenditure will be recorded during the sessions.Individuals will perform; static squat, dynamic toe raise, static abduction and dynamic squat exercises in both hips on a vibrating platform. All exercises will consist of 45 seconds of vibration and 15 seconds of rest. Each exercise will be repeated three times. Total intervention time will be 15 minutes. Participants will perform whole body vibration trainings at different frequencies in a randomized order with at least one day apart.

结局指标
主要结局
Blood pressure
时间窗: Change from the baseline to the first minutes after the intervention
Systolic and diastolic blood pressure will be measured with a sphygmomanometer.
Heart rate variability
时间窗: Change from the baseline to the first minutes after the intervention
Heart rate variability will be assessed by heart rate variability (HRV), a non-invasive measurement. Sympathetic and parasympathetic autonomic function will be evaluated with HRV software. HRV provides time and frequency domain parameters associated with autonomic function.
Arterial stiffness
时间窗: Change from the baseline to the first minutes after the intervention
Arterial stiffness will be measured with a noninvasive method with the help of the SphygmocorXCEL device, which can automatically measure with the cuff. The patient's age(years), gender(male), blood pressure(mmHg), height(cm), weight(kg), carotid-sternal notch distance between the artery, carotid-femoral artery as the distance between the entered data to the computer after increasing pressure over the brachial artery through a transducer (augmentation index) and again, carotid-femoral pulse wave velocity via the artery (pulse wave velocity) measurements will be made.
次要结局
- Heart rate(Change from the baseline to the first minutes after the intervention)
- Respiratory frequency(Change from the baseline to the first minutes after the intervention)
- Energy expenditure(During exercise intervention, average 15 minutes)
- Muscle strength(Change from the baseline to the first minutes after the intervention)
- Perceived effort(Change from the baseline to the first minutes after the intervention)
