Quick Overview

Scientists ran a PRISMA-registered systematic review and meta-analysis of 21 controlled trials on wholebody EMS in 540 sportspeople and athletes.

They searched five databases, extracted maximum strength and power of the hips and legs, pooled effects with a robust IVhet model, and scored quality with PEDro and TESTEX.

Overall, wholebody EMS produced a moderate strength gain (SMD 0.62) and a smaller power gain (SMD 0.38).

That evidence suggests wholebody EMS can help trained athletes add force and explosiveness—especially when stacked on existing drills or used as a joint-friendly stand-in for heavy lifting. Methods are transparent and conservative. Read the full post for protocols, limits, and who benefits most.

2026 German Hospital Review:  EMS Lifts Athlete Strength and Power

German sports scientists wanted a straight answer.
Can wholebody EMS help trained people get stronger and more explosive?

Prof. Wolfgang Kemmler led the project at University Hospital Erlangen.
That centre sits inside Friedrich-Alexander-Universität in Germany.
Prof. Michael Uder and Dr. Simon von Stengel worked beside him.
Franziska Adams pulled the trial data together.
Prof. Matthias Kohl at Furtwangen University handled the statistics.
Andre Filipovic from VfB Stuttgart brought elite-club experience.

They did not lean on one gym study.
They hunted every eligible trial they could find.
Five research databases were searched through early 2025.
The team followed the PRISMA review standard.
The plan was logged in PROSPERO before the write-up.
The finished paper was peer-reviewed and published in the journal Muscles.
The publisher is MDPI in Basel, Switzerland.
The science itself comes from a German university hospital.
Germany has a long record in physiology and sports research.

Eighteen projects passed the filter.
That produced 21 controlled studies.
About 248 people trained with wholebody EMS.
About 292 people served as comparison groups.
The volunteers were hobby players, advanced athletes, and professionals.
Most were in their twenties.
Sports included soccer, ice hockey, golf, and mixed gym work.

The sessions were short and practical.
Most plans used one or two bouts a week.
A typical bout lasted 9 to 30 minutes.
Most protocols used 80 to 90 Hz.
Impulse width was usually 300 to 400 microseconds.
Many trials stacked the current onto real squats, jumps, and lifts.
That is superimposed wholebody EMS.
It trains many muscle groups in one tight block of time.

Scientists then measured progress with hard tests.
They tracked maximum strength on leg press, squat, and knee extension.
They tracked power in watts on presses, extensions, and jumps.
They pooled those changes with a cautious statistical model.

The headline result was positive.
Lower-body maximum strength rose by an SMD of 0.62.
That is a moderate lift across the full set of trials.
The confidence interval ran from 0.08 to 1.16.
Lower-body power rose by an SMD of 0.38.
That interval ran from 0.06 to 0.70.
Both overall effects reached statistical significance.

Stacked wholebody EMS versus the same workout alone was smaller.
Strength there sat at SMD 0.44.
Power sat at SMD 0.39.
Those extra gains did not always clear the significance line.
Against ordinary resistance training, results looked broadly similar.
That still matters for busy athletes.
It means a short wholebody EMS block can sit in the same conversation as gym work.

Adding wholebody EMS to a normal training week looked brighter still.
In six of seven strength comparisons, the EMS group came out ahead.
Attendance was near 100% in studies that reported it.
Trials that logged harms did not tie serious events to the method.

The authors stayed careful.
Study quality was low to moderate on the PEDro scale.
TESTEX scores were higher, as that tool fits exercise trials better.
Results varied a lot from paper to paper.
Samples were often small.
So the extra benefit is not magic, and it is not identical in every sport.

The bright side is still clear.
Wholebody EMS can support maximum strength in trained athletes.
It can also support power, the quality behind jumps and rapid force.
Even a modest bump can matter when performance is already high.
The time cost is low.
Many major muscles can work in one supervised session.
For some players, that is a useful add-on to strength and power work.
For others, it is a compact option when a long weights session is harder to fit.

This article follows that Erlangen paper, not a sales script.
The names, hospitals, sample sizes, and effect sizes come from the published review.
Wholebody EMS is discussed here as a training method.

It is not offered as a medicine, a cure, or a treatment for disease.
The findings describe sportspeople in these trials.
They do not prove the same result for every beginner.

The full post walks through the protocols next.
It also shows where the evidence is strongest, and where it is still thin.
