Resumen:
INTRODUCTION: Whole body electrostimulation (WB-EMS) devices have been used in both performance and health related training programs and the scientific literature has shown that it can be an effective tool to improve training adaptations. However, WB-EMS efficiency
is being questioned nowadays. Further, it has been suggested that WB-EMS could lead to excessive physical strain and health problems
due to the lack of a scientific based specific WB-EMS training method and professional formation of coaches. The aim of this study was to
assess the training effects of two protocols of WB-EMS during a single maximal strength session.
METHODS: Eleven subjects with previous experience in strength training of 3-5 days/week during, at least, the past 3 years participated in
the study. They performed a familiarization trial with the WB-EMS device and a 1RM test based on mean propulsive velocity analysis for
bench press and full-squat to stablish their 90%1RM load. Then, subjects performed three maximal strength sessions consisting of 5 sets
of 5 repetitions with 3 minutes of rest between sets of bench press and full-squat using different protocols: WB-EMS with continuous
stimulus (85 Hz, 250/350 µs ; ...
