The Claim
Mean muscle fiber conduction velocity increases significantly during vibration-assisted low-force isometric contractions compared to non-vibrated contractions, indicating greater activation of larger, faster motor units.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
During low-force muscle contractions with vibration, the speed at which electrical signals travel along muscle fibers increases compared to contractions without vibration, suggesting that larger and faster muscle fibers are being recruited more intensely.
See the scientific wording
Mean muscle fiber conduction velocity increases significantly during vibration-assisted low-force isometric contractions compared to non-vibrated contractions, indicating greater activation of larger, faster motor units.
When vibration shakes the muscle during a light squeeze, it triggers sensors in the muscle that tell the spinal cord to turn on the strongest and fastest muscle fibers, which makes the electrical signals in the muscle travel faster.
What the research says
1 studyWhen vibration is added to a light muscle squeeze, the electrical signals in the muscle travel faster, which means the body is calling on its strongest, fastest muscle fibers to help out. The study proved this happens.
