The Claim
Prolonged static stretching generates mechanical tension that is associated with neuromuscular and morphological adaptations in calf muscles, potentially sharing physiological pathways with resistance training through mechanical tension-induced activation of anabolic signaling pathways such as mTOR.
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.
Holding a stretch for a long time might build muscle and strength in your calves by triggering the same biological signals that weightlifting does. Researchers think this happens because the stretch creates tension that activates growth pathways in your muscles, though we haven't directly proven this in humans yet.
See the scientific wording
Mechanical tension generated through prolonged static stretching is associated with neuromuscular and morphological adaptations in the calf muscles, suggesting that stretch-mediated hypertrophy and strength gains may share common physiological pathways with resistance training, potentially involving mechanical tension-induced activation of anabolic signaling pathways such as mTOR, though direct molecular evidence in humans remains to be established.
What the research says
1 studyThe study shows that holding a stretch for a long time daily builds calf muscle size and strength just as well as traditional weightlifting, likely because the muscle is under constant tension.
