The Claim
Doing light weightlifting with a band that restricts blood flow for six weeks can make both slow and fast muscle fibers in older people grow bigger by about 20%, even without heavy lifting.
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.
Doing light weightlifting with a band that restricts blood flow for six weeks can make both slow and fast muscle fibers in older people grow bigger by about 20%, even without heavy lifting.
See the scientific wording
Six weeks of low-load blood flow-restricted resistance exercise produces approximately 20% increases in the cross-sectional area of both type I and type II muscle fibers in healthy older adults aged 56–75, indicating fiber type-independent muscle hypertrophy.
What the research says
1 studyThe study found that doing light weight exercises with a special band that restricts blood flow made both kinds of muscle fibers in older adults grow about 20% bigger in just six weeks — no matter what type of muscle fiber it was.
