When rats swam for two hours and then consumed whey protein, their muscle building rate peaked at 60 minutes with a value of 7.76% per day.
Scientific Claim
In male Sprague-Dawley rats subjected to two hours of swimming exercise, whey protein concentrate ingestion was associated with a peak fractional synthesis rate (FSR) of 7.76% per day at 60 minutes post-ingestion.
Original Statement
“FSR tended to increase in all groups post-ingestion, although the initial peaks of FSR occurred at different times (WP, peak time = 60 min, FSR = 7.76%/day; MP, peak time = 90 min, FSR = 8.34%/day; CA, peak time = 120 min, FSR = 7.85%/day).”
Evidence Quality Assessment

appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
The claim describes an observed measurement without implying causation, which aligns with the study's design as a descriptive animal experiment.
