The Claim
In mice treated with a myostatin inhibitor, resistance exercise training and essential amino acids reduce Atrogin-1 mRNA expression, indicating that suppression of ubiquitin-proteasome activity contributes to increased muscle mass.
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 mice given a myostatin inhibitor, resistance exercise and essential amino acids lower Atrogin-1 mRNA levels, which is associated with reduced muscle protein breakdown and increased muscle mass.
See the scientific wording
In mice treated with a myostatin inhibitor, resistance exercise training and essential amino acids both reduced Atrogin-1 mRNA expression, a marker of muscle protein breakdown, suggesting suppression of ubiquitin-proteasome activity may contribute to muscle mass gains.
Blocking myostatin stops a signal that tells muscles to break down their own proteins. This allows muscle-building signals to activate and turns off a key enzyme that tags muscle proteins for destruction. Resistance exercise and essential amino acids further reduce this enzyme's activity, so muscles keep more of their proteins and grow larger and stronger.
What the research says
1 studyIn mice given a drug that blocks myostatin, both exercise and essential amino acids lowered a protein that breaks down muscle, helping the muscles grow bigger. This matches what the claim says.
