When rats exercised and then ate a small amount of whey protein hydrolysate, their muscles built protein faster than when they ate regular whey protein at the same dose.
Scientific Claim
In rats, whey protein hydrolysate ingestion at 0.5 g/kg body weight was associated with higher muscle protein synthesis rates compared to intact whey protein at the same dose 60 minutes after exercise.
Original Statement
“The FSR in the WPH groups was significantly higher than that of the WPC groups (main effect for treatment: p < 0.05; treatment × time: p=0.125).”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The study design (animal cohort) can support association claims but not causation. The use of 'associated' correctly reflects the evidence level.
