What is electrical muscle stimulation?
EMS applies electrical impulses through skin-contact electrodes to produce muscle contractions. Whole-body EMS coordinates stimulation across several major muscle regions. In practice, the device, electrode placement and selected programme together determine its use.
In E-Fit's training approach, impulses accompany active exercises. A trainer helps with movement execution and load adjustment. The person and the technology work together.
Why does gradual progression matter?
The 2023 international WB-EMS guideline highlights qualified supervision, an initial suitability assessment, careful onboarding for beginners and appropriate recovery periods. Load should be adjusted to the individual; higher intensity is not a goal in itself.
Before first use, follow the specific device's instructions and contraindications. Professional onboarding is a meaningful part of the product experience and cannot be replaced by a general online product explorer.
What can research tell us?
WB-EMS research investigates outcomes including muscle strength and body composition. The controlled TEST-III trial, for example, involved a defined group of older women and its own training protocol. The population and programme matter as much as the technology when interpreting such research.
An outcome measured with another device or protocol does not automatically become a verified effect of VOLTTA products. Final technical specifications and use conditions for VOLTTA development products require separate verification.
