WB-EMS Increase Energy Expenditure at Rest and During Uphill Walking Exercise

Study Overview
=================
Brief Summary
-----------------
Whole-body electrical stimulation (WB-EMS) has become increasingly popular as a tool to provide additional benefits compared to conventional exercise. However, the effects of the different electrical parameters on energy expenditure (EE) and respiratory exchange ratio (RER) remain poorly understood. This study aims to determine and compare the effects of different electrical frequencies applied with WB-EMS in EE and RER at supine resting and during uphill walking exercise

Detailed Description
-----------------
Obesity is a critical public health problem worldwide since it is a risk factor for cardiovascular diseases and mortality. Increased body weight and obesity are the results of an imbalance between energy intake and energy expenditure (EE). Body weight regulation and obesity are highly influenced by different factors such as genetic, physiology, and socioeconomics. It is well known that physical exercise is an effective strategy to increase EE, improve body composition, physical fitness, and cardiometabolic risk factors. Unfortunately, the principal barriers to abstaining from exercise are time constraints, the risk of injuries, and the lack of enthusiasm observed during the exercise sessions. In this context, whole-body electromyostimulation (WB-EMS) training is becoming increasingly popular worldwide as a potential and attractive alternative to traditional training methods to increase EE. The present study aimed to determine and compare the effects of different electrical frequencies applied with WB-EMS in EE and RER at supine resting and during uphill walking exercise.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Energy expenditure | Change in energy expenditure (kcal/min) by indirect calorimetry (Vyntus CPX Metabolic Cart) | It will be continuously measured through the entire test (60 minutes) of electromyostimulation with different impulse frequencies and intensities. | 
| Resting exchange ratio | Change in resting exchange ratio (kcal/min) by indirect calorimetry (Vyntus CPX Metabolic Cart) | It will be continuously measured through the entire test (60 minutes) of electromyostimulation with different impulse frequencies and intensities. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain perception | Change in pain perception in different body structures by Visual Analogue Scales. | It will be measured at timepoints after the administration of each impulse frequency and before and after the whole application of electromyostimulation. | 
| Impulse intensities | Change in impulse intensities in different body structures by whole-body electromyostimulation device. | It will be measured with at timepoints after the administration of each impulse frequency. |
