The Claim

In mouse gastrocnemius muscle, passive repetitive stretching is associated with increased phosphorylation of p70S6K, suggesting enhanced activation of a signaling pathway involved in muscle protein synthesis.

Source: Efficacy of passive repetitive stretching of skeletal muscle on myofiber hypertrophy and genetic suppression on MAFbx, MuRF1, and myostatin

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

In plain English

Stretching mouse leg muscles repeatedly seems to turn on a key switch inside the muscle cells that helps build new muscle protein.

What the research says

1 study

  1. Study: Efficacy of passive repetitive stretching of skeletal muscle on myofiber hypertrophy and genetic suppression on MAFbx, MuRF1, and myostatin

    The study stretched mouse leg muscles the same way described in the claim and found that it turned on a key signal for building muscle, just like the claim says.
