Quick Overview
Scientists at Germany’s Institute of Medical Physics, Friedrich-Alexander University of Erlangen-Nürnberg, tested 54 male amateur golfers aged 18-70 in a randomized controlled study.
For 16 weeks, one group received supervised once-weekly 20-minute whole-body electromyostimulation.
Researchers carefully measured maximum trunk strength, leg and hip strength, and lean body mass.
The EMS group gained significantly more trunk strength (p<0.001), leg strength (p=0.001) and lean mass (p=0.034) than the control group, with near-perfect attendance and no serious issues.
These measurable gains in strength and stability support a more powerful, controlled golf swing. Published in a peer-reviewed international journal, the clear results make the full findings worth reading.

Researchers in Germany put once-weekly EMS to the test with real amateur golfers.

They wanted clear answers on strength, stability and body composition.
The team worked at the Institute of Medical Physics at Friedrich-Alexander University of Erlangen-Nürnberg.
This is a respected research centre in a country with a long record of careful science.
Their work appeared in the peer-reviewed International Journal of Environmental Research and Public Health.

Fifty-four healthy male amateur golfers took part.
Ages ranged from 18 to 70.
They were randomly split into two equal groups of 27.
One group received supervised whole-body electromyostimulation once a week.
Each session lasted just 20 minutes.
The other group kept their normal routine.
After 16 weeks the results stood out.
Maximum trunk strength rose clearly in the EMS group.

The gain was 10.7 units while the control group lost a little.
The difference reached high statistical strength.
Leg and hip strength also improved.

The EMS group added 261 units of force.
The control group managed only 57.
Again the gap was solid and meaningful.

Lean body mass moved in the right direction too.
EMS users gained a modest amount of muscle.
The control group lost some.
The difference between groups was significant.
Attendance stayed near perfect.
No one reported serious problems from the sessions.
These gains matter for golf.

Stronger trunk muscles support a more stable swing.
Better leg strength helps generate power from the ground up.
Extra lean mass can aid overall control and endurance on the course.

The study shows that even one focused EMS session each week can deliver measurable progress.
It offers a time-efficient way to build the physical base many golfers need.
