ABSTRACT
BACKGROUND: This systematic review and meta-analysis set out to determine the efficacy of whole-body muscle electrostimulation on body composition, strength, and muscle power in active and non-active adults (aged ≥18 years). METHOD: This review was reported in accordance with the Protocol Statement of Preferred Reporting Element Guidelines for Systematic Reviews and Meta-Analysis included controlled trials; whole-body electromyostimulation trials with at least 1 exercise and control group; participants >18 years old. Outcome measures were defined as standardized mean differences for muscle mass, body fat mass, strength, and power. Studies were searched in the following electronic databases: PubMed, Web of Science, Scopus, SPORTDiscus, and EMBASE for all articles published up to July 30, 2021. The risk of bias was assessed by 2 independent researchers using the Physiotherapy Evidence Database scale and Grading of Recommendations, Assessment, Development and Evaluations approach. Analyses were performed using the metafor package of the statistical software R (version 4.0.3; R Core Team, 2020). Random effects models, forest, and funnel plots to quantify the asymmetry associated with publication bias were fitted using the metafor library in R. Statistical heterogeneity was assessed using I2 statistics. RESULTS: In total, 26 studies representing 1183 participants were included (WB-electromyostimulation: n = 586 and control group: n = 597). The mean age of the participants ranged from a minimum of 20.4 to a maximum of 77.4 years old. Interventions lasted a minimum of 4 and a maximum of 54 weeks. Standardized mean difference was 0.36 (95% confidence interval [CI]: 0.16-0.57) for muscle mass, -0.38 (95% CI: -0.62-0.15) for body fat, 0.54 (95% CI: 0.35-0.72) for strength, and 0.36 (95% CI: 0.02-0.71) for power with significant differences between groups (all P < .04). I2 revealed low heterogeneity of muscle mass (15%) and power (0%) between trials and medium heterogeneity of body fat (45%) and strength (55%). CONCLUSION: We concluded that WB-electromyostimulation has significant positive effects on muscle mass, body fat, strength, and power.

Whole Body Electromyostimulation [WB-EMS] is a training methodology that applies electrostimulation in the main muscle groups of the human body superimposed with active training exercises. This study aims to carry out a bibliometric analysis on WB-EMS to provide an overview of the state of research and provide new insights for research in the field. METHOD: One hundred and two citations extracted were examined using a bibliometric approach based on data stored in the Web of Science Core Collection, applying traditional bibliometric laws, and using VOSviewer and excel for data and metadata processing. RESULTS: Among the results, this study points out that Germany is the country that produces more scientific knowledge on WB-EMS. Wolfgang Kemmler is the most relevant author in this field. Moreover, Frontier of Physiology is the journal where the authors publish the most. CONCLUSION: Research on WB-EMS has been growing in recent years. German and Spanish researchers lead two clusters where most studies and collaborations in this field are carried out. These findings will provide a better understanding of the state of WB-EMS research and may guide the emergence of new lines of investigation and research ideas.
ABSTRACT
(1) Introduction: Whole Body Electromyostimulation is a technological and time efficient personal training practiced all over the world. With the increase of practitioners in the last 10 years, the need to study more about practitioners has arisen, so this pilot study aims to trace a user profile of this method through the analysis of socio-demographic data for a better understand of the profile of people looking for this type of training to improve the effectiveness of the intervention and develop programs that are in accordance with the motivation of practitioners. (2) Methods: 270 users from 5 countries answered an online questionnaire with socio-demographic questions. Data were treated using descriptive statistics. Possible differences between sexes and between groups were analyzed by means of non-parametric statistical tests: Mann−Whitney U-test (continuous variables); in addition to studying possible dependence relationships and differences between proportions, using the Chi-square statistic with pairwise z-test using the Bonferroni correction (categorical variables). (3) Results: Middle-aged women are the main user of this type of training. The majority of WB-EMS users do another type of physical activity with significant difference between men and woman (p < 0.05) men are more active than women. Weight loss, health and wellness and muscle mass increase are the main goals of the WB-EMS users. There are significant differences in weight loss and rehabilitation between genders (p < 0.05). Women look much more than men to lose weight and men look more than women to rehabilitation. (4) Conclusions: The user profile is a physically active woman, aged 35−49 years, with normal weight and high educational level, who carries out twice weekly full body electrostimulation training with the goals of weight loss, health and/or wellness and muscle mass gain.

INTRODUCCIÓN: La electroestimulación es un método de entrenamiento utilizados en el ámbito deportivo que ha demostrado ser efectivo para mejorar manifestaciones de fuerza como la potencia muscular. Actualmente, no se conoce literatura científica en la que se aplique un programa de entrenamiento con traje de electroestimulación. Por ello, este estudio pretende llevar a cabo un programa para ver qué efectos tiene sobre las adaptaciones neuromusculares en sujetos no entrenados. OBJETIVO: estudiar las alteraciones neuronales y musculares que ocurren en el entrenamiento activo de electroestimulación aplicada con traje de cuerpo entero en los músculos extensores de brazos y extensores de la pierna. MATERIAL Y MÉTODOS: Se realizará un estudio controlado aleatorizado entre grupos. El diseño experimental del estudio permitirá analizar las adaptaciones neuromusculares que ocurren con el entrenamiento de electroestimulación aplicada con traje de cuerpo entero y compararlas a las de un entrenamiento de fuerza tradicional. Las variables dependientes medidas serán: actividad electromiografía en test de fuerza isométrica máxima, valor de fuerza máxima, tasa de producción de fuerza, indicadores de adaptación neurales. El programa se llevará a cabo durante 24 sesiones, 2 veces por semana, durante 12 semanas.

INTRODUCTION: Electrostimulation is a method of training used in sports that has been shown to be effective in improving strength manifestations such muscle power. Currently, there is no known scientific literature in which a training program with electrostimulation suit is applied. Therefore, the aim of this study is to carry out a program to see the effects on neuromuscular adaptations in untrained subjects. OBJECTIVE: to study the neuronal and muscular adaptations that occur in the active electrostimulation training applied with a full body suit on the extensor muscles of the arms and extensors of the leg. MATERIAL AND METHODS: A randomized controlled study between groups. The experimental design of the study will allow us to analyze the neuromuscular adaptations that occur with the electrostimulation training applied with a full body suit and compare them to those of a traditional strength training. The dependent variables measured will be: electromyography activity in maximum isometric force test, maximum force value, force production rate, neural adaptation indicators. The program will be carried out during 24 sessions, twice a week, for 12 weeks. EXPECTED RESULTS: We expect to achieve greater neuromuscular activation with the combination of electrostimulation applied with full body suit. Regardless of the results obtained, the final study will be published
