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

Scientific Claim

In male Sprague-Dawley rats subjected to two hours of swimming exercise, milk protein concentrate ingestion at doses of 0% to 100% of 3.09 g/kg body weight was associated with a dose-dependent increase in fractional synthesis rate, with no significant difference observed between 100% and 150% doses.

Original Statement

“We found that MP doses between 0% and 100% caused an increase in FSR in a dose-dependent manner, whereas there was no significant difference between the 100% and 150% doses (Figure 7).”

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

definitive

Can make definitive causal claims

Assessment Explanation

The claim describes observed dose-response relationships without implying causation, which aligns with the study's design as a descriptive animal experiment.

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.

94%

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.

90%

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.

86%

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.

84%

After swimming, rats that drank whey protein had more leucine in their blood than those drinking other proteins at 1 and 1.5 hours after eating.
