The Claim
Blood flow-restricted resistance exercise increases vastus lateralis cross-sectional area by 7.7% in national-level powerlifters, which is significantly greater than the 0.5% change observed with conventional 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.
When top powerlifters do a special type of exercise that limits blood flow to their muscles, their thigh muscle size grows almost 8% bigger—way more than the tiny growth from normal workouts.

What the research says
1 studyStudy: Type 1 Muscle Fiber Hypertrophy after Blood Flow–restricted Training in Powerlifters
The study tested the same type of exercise with restricted blood flow in powerlifters and found exactly what the claim says: a big increase in muscle size compared to normal training.
