Effects of local vibrations on skeletal muscle trophism in elderly people: mechanical, cellular, and molecular events.

Cohort Study

Human

2009 Oct

The study gave older adults with muscle loss 12 weeks of vibrating therapy on their thighs, and their muscles became stronger and switched to faster-twitch fibers — without getting bigger, just like the claim said.

Similar Assertions

When older adults with muscle loss do 12 weeks of gentle vibrating therapy on their muscles, their muscle cells start changing how they use energy, repair muscle fibers, and handle stress — like turning on better internal maintenance modes.
