FIGURE 2.

Delta change (postprandial postexercise increase) in muscle protein synthesis rates (MPS), early (0–2 h) and during the entirety of the postprandial period, expressed as fractional synthetic rate (FSR), in response to a leucine dose in all participants (77 study arms) (a), young participants (45 study arms; 19–29 years) (b) and older participants (32 study arms; 57–74 years) (c). Squares represent whole food sources. Data were analyzed by linear regression; coefficient of determination (r ²), p value, and y‐intercept (b ₀) are presented.
