Immediate Effect of Whole-Body Vibration on Cardiovascular Response and Functional Capacity in Overweight/Obese Young Women

December 5, 2025 updated by: Rokaia Ali Zainelabedeen Mohamed Toson, Cairo University
Obesity has become a major global public health issue, defined by an excessive accumulation of body fat that presents substantial health risks. Over 650 million adults worldwide suffer from obesity, which is defined as having a Body Mass Index (BMI) of 30 or higher. Obesity is becoming more common in both developed and developing countries. Sedentary lifestyles, unhealthy eating habits that include processed foods and sugars, and genetic factors are the main causes of the rising prevalence of obesity. Obesity is a multifactorial condition that affects physical appearance and self-esteem, while also having significant implications for long-term health, leading to decreased life expectancy and lower quality of life.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Females aged 18 to 25.
  • normotensive (<140/90 mmHg).
  • Their BMI was from 25 to 40 kg/m2.
  • Sedentary (≤ 90min of regular exercise per week).

Exclusion Criteria:

  • Having previously diagnosed with any chronic disease.
  • Cardiorespiratory or neuromuscular conditions.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Study Group (Whole body vibration group)
The study group (no = 13) underwent single session of whole-body vibration (WBV) of using the PowerPlate device.
Device: Whole-body vibration device
Whole-body vibration (WBV) training using the Power Plate Pro 7HC (Northbrook, USA). The vibration frequency was set at 30 Hz, with an amplitude of 2 mm.
Experimental: Control group (Sham whole body vibration group)
The sham WBV group (no=13) will stand on the same device with the vibtation shut off for single session.
Other: Sham whole body vibration
A sham Whole body vibration will be used . participants will stand on the device without actual vibrations.This control condition will be used to isolate the effects of WBV from other potential influences such as standing posture and time spent on the the platform.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Brachial blood pressure
Time Frame: 1 day
Systolic brachial blood pressure and diastolic brachial blood pressure will be measured using a blood pressure (BP) monitoring device after 15 minutes rest.
1 day
Heart rate
Time Frame: 1 day
Heart rate will be measured using a pulse oximeter after 15 minutes rest.
1 day
Arterial O2 saturation
Time Frame: 1 day
Arterial oxygen saturation of pulse oximetry (SpO2) were measured using a pulse oximeter.
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
6-Minute walk test
Time Frame: 1 day
The 6-Minute Walk Test (6MWT) is a simple, practical assessment used to measure functional exercise capacity. It evaluates how far a person can walk on a flat, hard surface (usually 30 meters) in six minutes. It is widely used in cardiology, pulmonology, and rehabilitation.
1 day
The Borg scale
Time Frame: 1 day
The Borg Scale is a tool used to measure a person's perceived exertion and how hard they feel they are working during physical activity. It is commonly used during cardiac rehab, pulmonary rehab, exercise training, and clinical assessments. the scale ranges from 6 represents no exertion at all and to 20 represents maximal exertion.
