After doing blood flow-restricted exercise, the ultrasound images of muscles didn’t show any change in texture with different cuffs, but when more pressure was applied, the images suggested the muscle tissue became slightly more watery.
Scientific Claim
Echo intensity, a measure of muscle tissue quality, remains unchanged after blood flow-restricted exercise in men and women regardless of cuff width, but decreases with higher applied pressure in a separate experiment.
Original Statement
“Echo intensity remained unchanged. ... Echo intensity decreased in both conditions and to a greater extent with a higher applied pressure.”

Appropriate Language Strength

Assessment Explanation
The abstract uses neutral language ('remained unchanged', 'decreased') and reports findings without causal claims. The inconsistency across experiments supports cautious interpretation.
Evidence from Studies
Supporting (0)
Contradicting (1)
The study found that muscle texture (echo intensity) didn’t change with different cuff widths, but it did get worse with higher pressure — so the claim that it 'stays the same' after this kind of exercise is wrong.
