The Claim
In mice, passive repetitive stretching of the gastrocnemius muscle performed 15 times per minute for 15 minutes, 5 days per week over 2 weeks is associated with an increase in myofiber cross-sectional area, suggesting a cellular-level structural adaptation indicative of muscle hypertrophy.
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 mouse leg muscles regularly for two weeks seemed to make the muscle fibers grow bigger, which could mean the muscles got stronger at a microscopic level.
See the scientific wording
Passive repetitive stretching of the gastrocnemius muscle in mice, performed 15 times per minute for 15 minutes, 5 days per week over 2 weeks, was linked to an increase in myofiber cross-sectional area, indicating a structural adaptation toward muscle hypertrophy at the cellular level.
What the research says
1 studyThe study did the exact stretching routine described and found that it made muscle fibers bigger in mice, which means the claim is backed by the evidence.
