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.
Interventions
OTHERWB-EMS
The group has been submitted to 2 experimental conditions: 1. At rest with superimposed WB-EMS. 2. During uphill walking exercise with superimposed WB-EMS.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Energy expenditure | It will be continuously measured through the entire test (60 minutes) of electromyostimulation with different impulse frequencies and intensities. | Change in energy expenditure (kcal/min) by indirect calorimetry (Vyntus CPX Metabolic Cart) |
| Resting exchange ratio | It will be continuously measured through the entire test (60 minutes) of electromyostimulation with different impulse frequencies and intensities. | Change in resting exchange ratio (kcal/min) by indirect calorimetry (Vyntus CPX Metabolic Cart) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain perception | It will be measured at timepoints after the administration of each impulse frequency and before and after the whole application of electromyostimulation. | Change in pain perception in different body structures by Visual Analogue Scales. |
| Impulse intensities | It will be measured with at timepoints after the administration of each impulse frequency. | Change in impulse intensities in different body structures by whole-body electromyostimulation device. |
