The Claim
In recreationally active untrained adults, six weeks of low-load resistance training with blood flow restriction does not produce statistically significant changes in extracellular spacing around muscle fibers when compared to high-load resistance training.
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 weight training with blood flow restriction doesn't change the space around muscle fibers any more than heavy weight training in regular active people — after six weeks, both seem to have the same effect.
See the scientific wording
Six weeks of low-load resistance training with blood flow restriction does not significantly alter extracellular spacing around muscle fibers in recreationally active untrained adults, with no statistically significant changes observed compared to high-load resistance training.
What the research says
1 studyThe study looked at whether low-weight training with restricted blood flow changes the space around muscle fibers, and found it doesn’t — just like the claim says.
