// Aim of study
The goal of the present study was to compare classic strength training methods with dynamic whole body EMS with regard to their effects on strength and speed.
//Methodology
80 sports students were randomized into equal parts into classic training groups for hypertrophy, maximum strength, quickness and muscular endurance, the modern procedure for full-body or whole body EMS and vibration, as well as the two mixed groups, whole body EMS/hypertrophy and vibration/hypertrophy.
The classic training groups worked on the leg curl and leg extension musculature on (Gym80) machines in the respective groups in 3 series with various additional weights (30-90%, 3-15 repetitions).
The EMS groups executed side steps and knee bends without additional weights (load/interval 6 s/4 s, pulse frequency 85 Hz, pulse width 350 μs, bipolar rectangular pulse (60% intensity). Standardization was via visual biofeedback.
The training took place twice a week over a period of 4 weeks. Entry and exit tests were carried out on strength diagnostic machines before and after the training as well as after a two-week regeneration phase. The dynamics were measured by means of performance (strength x speed) with 40% and 60% additional load at various angles.
// Results
All types of strength training were able to improve maximum performance significantly.
– Maximum strength improved the most, 16%, within the hypertrophy group, followed by 9-10% for EMS.
Only the EMS groups showed significant improvement in speed.
– The measured speed performance improved by about 30% – significantly more than by classic methods (16-18%). This is apparently due to EMS‘s direct control of fast-twitch muscle fibers.
Mixed training designs such as EMS and classic hypertrophy training show the typical changes that result from the two training stimuli (a maximum 7 % growth in strength and 12% improvement in performance).
Combinations of classic and modern training procedures could thus open up new, promising configurations of stimuli.
Long-term effects of whole body EMS must, in particular, be emphasized. The greatest boosts in performance appear after a two-week period of regeneration.
// Conclusion
Compared with various types of training to boost strength and speed, dynamic whole body EMS training with miha bodytec has been shown to be a highly effective training method. Whole body EMS was the sole form of training able to improve maximum sports performance in speed of movement. In addition, pronounced long-term effects are opening up new possibilities in training periodization.A carefully dosed amount of whole body EMS together with the dynamic execution of movement represents a promising combination for strength and speed training.Copyright 2010 miha bodytec GmbH – Gubener Str. 13½ – 86156 Augsburg – Tel.: +49 (0)821 45 54 92 – 0
