The Claim

Whole-body vibration training combined with oral vitamin D supplementation is associated with increased serum irisin levels and decreased serum myostatin levels in older adults with osteosarcopenia.

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.

In plain English

When older people with weak bones and muscles do whole-body vibration exercises and take vitamin D pills, their bodies seem to produce more of a helpful muscle protein (irisin) and less of a muscle-limiting protein (myostatin).

What the research says

1 study

  1. Study: Effects of 12 Weeks of Whole-Body Vibration Training and Vitamin D Supplementation on Bone Density and Muscle Quality in the Aged with Osteosarcopenia: A Randomized Controlled Trial

    The study gave older adults with muscle and bone loss both vibration therapy and vitamin D pills, and found that their body made more irisin (a helpful muscle protein) and less myostatin (a protein that stops muscle growth), just like the claim said.
