When rats swam for two hours and then consumed caseinate, their muscle building rate peaked at 120 minutes with a value of 7.85% per day.

Scientific Claim

In male Sprague-Dawley rats subjected to two hours of swimming exercise, caseinate ingestion was associated with a peak fractional synthesis rate (FSR) of 7.85% per day at 120 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).”

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.

Similar Assertions

When rats swam for two hours and then consumed milk protein, their muscle building rate peaked at 90 minutes with a value of 8.34% per day.

83%

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.

82%

When measuring overall muscle building over several hours, milk protein showed the highest total effect, then caseinate, whey, and soy, but the numbers weren't statistically tested.

76%

When rats ate more milk protein up to a certain amount, their muscle building increased, but eating even more didn't help further.

76%

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.
