The Claim
Neither blood flow restriction resistance exercise nor high-load resistance exercise significantly increases thigh circumference in untrained young males after 8 weeks of training, with measurements taken one week post-intervention.
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.
In untrained young men, eight weeks of either blood flow restriction resistance training or traditional heavy lifting does not result in a measurable increase in thigh size when measured one week after training ends.
See the scientific wording
Neither blood flow restriction resistance exercise nor high-load resistance exercise significantly increases thigh circumference in untrained young males after 8 weeks, suggesting that muscle growth from these protocols does not result in measurable changes in overall thigh girth when assessed one week after training.
When muscles grow larger from exercise, the surrounding fat layer gets thinner at the same time, so the overall thickness of the thigh stays the same even though the muscle inside is bigger.
What the research says
1 studyAfter 8 weeks of either light or heavy leg workouts, the guys' thighs didn't get noticeably bigger around, even though their muscles got stronger and thicker inside — likely because any temporary swelling from exercise went away by the time they measured.
