FIGURE 5.
Total postprandial plasma leucine availability, represented as incremental area under the curve over 180 min, in response to a leucine dose provided as a bolus protein ingestion within an hour of resistance exercise in all participants (61 study arms) (a), young participants (35 study arms; 19–29 years) (b) and older participants (26 study arms; 57–74 years) (c). Delta change (postprandial postexercise increase) in muscle protein synthesis rates (MPS), expressed as fractional synthetic rate (FSR) in relation to total postprandial leucine availability in all participants (d), young participants (e) and older participants (f). Data were analyzed by linear regression; coefficient of determination (r 2), p value, and y‐intercept (b 0) are presented.
