Immediate Effects of Whole Body Vibration on Hemodynamic Response and Fatigue in Normotensive People With Obesity

Study Overview
=================
Brief Summary
-----------------
Whole Body Vibration Therapy (WBVT) has been identified as a useful tool to increase peripheral blood flow. The present study aimed at how dynamic exercises with WBVT immediate effect on hemodynamic response and fatigue parameters in patients with obesity.

Design Details

Primary Purpose: Diagnostic
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Active Whole Body Vibration (aWBVT) group, performed ten dynamic standard exercises on a vibration platform. The vibration protocol lasted for 15 minutes, in a frequency of 30 Hz and amplitude of 2 mm. Control group performed only ten dynamic standard exercises with no vibration application. Blood Pressure, heart rate, saturated oxygen were measured for the hemodynamic response. Modified Borg Dyspnoea Scale (MBDS) and The Borg Rating of Perceived Exertion (BRPE) Scale were used in order to evaluate fatigue level. All evaluations were performed at the beginning of the study, at the end of the session and at the recovery period
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Active Whole Body Vibration Training<br>Exercises were taught during the first session, active training was done in the second session, and acute evaluations were made during the third session. Both groups performed the dynamic exercises, under supervision, on the whole body vibration device with 10-second rest intervals. Throughout the WBVT session, the vibration amplitude was set to 2 mm and exercise frequency 30 Hz. | Other: Whole Body Vibration Training<br>* Whole Body Vibration Training (WBVT) method has been used as an alternative to conventional strengthening exercises. In this method, the patient stands on the platform of the WBVT device in a static position or performs dynamic exercises, the mechanical vibration produced by the device is transferred to the body<br>* Other names: Standard Exercise;|
| Active Comparator: Control Group<br>The same exercises as the aWBVT group were performed on the vibration platform, with the vibration application turned off | Other: Whole Body Vibration Training<br>* Whole Body Vibration Training (WBVT) method has been used as an alternative to conventional strengthening exercises.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Heart rate | Heart rate was evaluated from the brachial artery using a sphygmanometer. | 20 minute | 
| Blood pressure | Blood pressure was evaluated using a sphygmomanometer. | 20 minute | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Fatigue | Borg's Rating of Perceived Exertion Scale. Minimum score: 6 Maximum score: 20 The Borg Rating of Perceived Exertion scale helps estimate activity intensity. | 20 minute |
