The Claim
Chronic static stretching may induce strength gains that are partially mediated by neural adaptations, such as improved motor unit recruitment and rate coding, rather than solely by muscle hypertrophy.
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.
Regular static stretching might make you stronger not just by building bigger muscles, but by teaching your nervous system to fire muscle fibers more efficiently. This means your brain and nerves get better at activating muscles, which can boost strength even without visible muscle growth.
See the scientific wording
Some strength gains from chronic static stretching may be partially mediated by neural adaptations rather than solely muscle hypertrophy, as evidenced by contralateral strength increases in non-stretched limbs and strength improvements exceeding morphological changes. This suggests stretching may improve motor unit recruitment or rate coding independent of muscle size.
What the research says
1 studyThe study shows that regular stretching makes you stronger and builds a little muscle, with strength gains slightly outpacing muscle growth, which hints that your nervous system might also be getting better at using your muscles, not just that the muscles are getting bigger.
