The Claim
In mice, passive repetitive stretching is associated with reduced mRNA expression of MuRF1, MAFbx, and myostatin—genes involved in muscle protein degradation and inhibition of muscle growth—indicating a potential suppression of catabolic and anti-hypertrophic pathways in skeletal muscle.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Stretching mice passively over time might help reduce the activity of genes that break down muscle and block muscle growth, suggesting it could help protect against muscle loss.
See the scientific wording
Passive repetitive stretching in mice was associated with downregulation of mRNA expression for MuRF1, MAFbx, and myostatin—genes involved in muscle protein degradation and growth inhibition—suggesting suppression of catabolic and anti-hypertrophic pathways in skeletal muscle.
What the research says
1 studyThe study tested gentle, repeated stretching in mice and found it reduced levels of genes that break down muscle and block growth, which supports the claim.
