Resting and Maximum Plasma Leucine ConcentrationPrimary· A 5-hour period.
The amount of leucine in the plasma at rest, following an overnight fast. Then maximum concentration of plasma leucine was the higher concentration observed following ingestion of the drink. The maximum amount can be different for everyone but typically occurs 45 to 75 minutes after consumption of the amino acid drink

Sponsor's own description
This study proposes to characterize skeletal muscle amino acid kinetics to an EAA challenge, i.e., an oral amino acid tolerance test (OATT), in order to determine the state of muscle health. Analogous to the oral glucose tolerance test (OGTT) used to characterize alterations in glucose metabolism, the proposed OATT represents a potential low-cost solution to classifying patients' skeletal muscle health. The extrapolation of this work is the development of a simple analytical tool that would provide clinicians the ability to discern alterations in muscle amino acid kinetics prior to a loss of function.
