When rats swam for two hours and consumed dairy proteins (whey, milk, or caseinate), their muscle building rates were higher than those eating soy protein at specific times after eating.
Scientific Claim
In male Sprague-Dawley rats subjected to two hours of swimming exercise, whey protein concentrate, milk protein concentrate, and caseinate were associated with significantly higher fractional synthesis rates compared to soy protein concentrate at specific time points (whey protein at 60 minutes, milk protein at 90 and 120 minutes, caseinate at 120 minutes).
Original Statement
“Milk-derived proteins caused significantly greater increases (p < 0.05) in FSR compared with SP at different times (WP, 60 min; MP, 90 and 120 min; CA, 120 min).”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
The claim describes observed differences in FSR between protein groups without implying causation, which aligns with the study's design as a descriptive animal experiment.
