Can four weeks of muscle stimulation change performance? Or does it only feel intense in the moment?

Maybe you train hard already. But your legs still feel heavy. Your jump feels lower than before. Or your strength plateaus despite effort.

That frustration feels familiar.

A published study in the Journal of Strength and Conditioning Research explored this. Researchers from the University of Burgundy and Italian institutions followed 12 regional volleyball athletes.

They added high-frequency EMS three times per week. Each session lasted about 12 minutes. No extra weight training was added.

After four weeks, repeated jump performance showed improvement. Mechanical power showed a measured increase. Single jumps improved after continued sport-specific practice.

The changes were not instant. They were gradual. They appeared after structured training and recovery.

Why does this matter?

EMS stimulates motor nerves directly. That creates controlled muscle contractions. It may help recruit muscle fibers differently than voluntary effort alone.

For someone with muscle weakness, this is interesting. For someone already training, it may support performance. For existing EMS users, it reinforces consistency matters.

The study was peer-reviewed. It used repeated measurements. It followed a structured training protocol.

It did not claim miracles. It observed measurable changes.

That is the important difference.

If you want to understand how EMS was used, what parameters were applied, and what realistic expectations look like, there’s more detail in the full article.
