Entrenamiento EMS: ¿qué dice la ciencia?
El entrenamiento EMS es un entrenamiento de cuerpo completo que te ayuda a perder peso, mejorar la fuerza y estimular el crecimiento muscular. Además, puede ayudar a aliviar tensiones y corregir desequilibrios musculares, lo que puede hacer desaparecer dolores de espalda, por ejemplo.
Impulsos eléctricos absolutamente inofensivos se transmiten a los músculos subyacentes a través de los nervios. Normalmente, estos impulsos son controlados por el cerebro. Sin embargo, el músculo no puede distinguir si el impulso proviene del cerebro o de la PowerBox de eaglefit. El resultado es el mismo: el músculo se contrae. Además, se activan más fibras musculares que sin EMS. Adicionalmente, la musculatura profunda se puede activar mejor que con métodos convencionales (especialmente para principiantes). Dado que no es necesario mover pesos pesados, el EMS también es más suave para las articulaciones.

Effects of Whole-Body Electromyostimulation versus High-Intensity Resistance Exercise on Body Composition and Strength: A Randomized Controlled Study
Thus, Whole Body-EMS can be considered as an attractive, time-efficient, and effective option to HIT-resistance exercise for people seeking to improve general strength and body composition.
Effect of Electromyostimulation Training on Muscle Strength and Sports Performance
After 12 weeks of carefully monitored procedures, the EMS group showed a significant increase in maximal concentric/eccentric torque, squat strength, and squat and drop jump height, compared with the controls. Based on these findings, 12 weeks of EMS training had a significant effect on muscle strength.
Does whole-body electrical muscle stimulation combined with strength training promote morphofunctional alterations?
The results of the study demonstrated that the 20-minute exercise plus EMS regimen was more effective for strength gains and lean mass maintenance than traditional isolation training.
Electromyostimulation - a systematic review of the effects of different electromyostimulation methods on selected strength parameters in trained and elite athletes
With regard to the level of fitness, the analysis shows that trained and elite athletes, despite their already high level of fitness, are able to significantly enhance their level of strength to same extent as is possible with untrained subjects.
After a stimulation period of 3-6 weeks, significant gains were shown in maximal strength (isometric Fmax +58.8%; dynamic Fmax +79.5%), speed strength (eccentric isokinetic Mmax +37.1%; concentric isokinetic Mmax + 41.3%; rate of force development + 74%; force impulse + 29%; vmax + 19%), and power (+67%).
