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

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.

Treatment and study plan

Whole-body Vibration Device

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.

Sham Whole body vibration

Other

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.

Primary outcomes

  1. 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.

  2. Heart rate

    Time frame: 1 day

    Heart rate will be measured using a pulse oximeter after 15 minutes rest.

  3. Arterial O2 saturation

    Time frame: 1 day

    Arterial oxygen saturation of pulse oximetry (SpO2) were measured using a pulse oximeter.

Secondary outcomes

  1. 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.

  2. 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.
