The Claim
Muscle biopsy measurements of fiber cross-sectional area exhibit poor correlation (r<0.25) with whole muscle ultrasound measurements and strength improvements, suggesting limitations in relying solely on biopsy data to evaluate training-induced hypertrophy.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When scientists check muscle growth from exercise, taking tiny muscle samples doesn't match up well with other methods like ultrasound scans or strength tests, so using just the sample data isn't a great way to measure progress.
