Rats exercised then ate different proteins. Some made muscles grow faster.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.
Systematic Reviews & Meta-Analyses
Max 100Randomized Controlled Trials
Max 90Cohort Studies
Max 72Case-Control Studies
Max 58Cross-Sectional Studies
Max 44Case Reports & Case Series
Max 30Expert Opinion & Narrative Reviews
Max 515 / 72
Evidence Score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

Whey protein maximizes muscle protein synthesis, steak provides higher nutrient density, and collagen specifically supports connective tissue repair and recovery.
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.
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.
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.
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.
