Berlin (dpa / tmn) - In EMS training, muscles are stimulated with electronic impulses.

The units are short at around 20 minutes.

But the training should not be underestimated, warns sports medicine specialist Prof. Klaus Völker in the magazine “test” (issue 10/2020).

EMS training that is too intensive and too frequent can - just like excessive strength training - destroy muscles.

But the risks are calculable if the trainer has mastered his craft, adjusts the voltage appropriately and takes into account how resilient the customer is, according to the expert.

Mediocre test result

The Stiftung Warentest recommends that trainers should have a basic qualification in the field of sports and an additional qualification as an EMS trainer.

She tested six major EMS providers in Germany.

The result is mediocre in terms of the grades - the overall ratings are between 2.5 and 3.3.

According to Völker, one advantage of EMS training is that more muscle groups are trained at the same time than with conventional strength training and that the muscles are strengthened by the electronic impulses down to the deep layers.

EMS has an above-average effect on the back and can prevent tension pain and alleviate it demonstrably.

But: According to the product testers, it does not replace endurance sports or agility training.

It is also rather unlikely that you can lose a lot of weight with EMS training alone.

Suitable for many - but not for everyone

The entry hurdles are low: whether old or young, trained or untrained - it doesn't matter.

However, pregnant women, people with cardiac arrhythmias, diabetes or cancer and people with an implanted pacemaker should not do EMS training.

EMS studios, which are based on the official DIN standard, are only allowed to offer beginners one training session per week.

From the eleventh week of training, it is okay if there are at least four days between the units.

It is also important that a trainer may supervise a maximum of two people at the same time.

And the cost?

The weekly fee at the tested studios was between around 20 and 40 euros.

In addition, there is a one-time fee of between 50 and 200 euros, for example for advice, analysis, training cards - in some cases there is also the necessary functional clothing that you wear under the vest and cuffs.

You have to buy this otherwise, or you can rent it for a fee.
