TL;DR: Despite differences in the time course of plasma phenylalanine kinetics and a greater residual IC phenylAlanine concentration, amino acid supplementation acutely stimulated muscle protein synthesis in both young and elderly individuals.

TL;DR: It is indicated that fat oxidation is normally impaired during exercise at 85% VO2max because of the failure of FFA mobilization to increase above resting levels, but this explains only part of the decline in fat oxidation when exercise intensity is increased from 65 to 85%VO2max.

TL;DR: Net muscle protein synthesis in healthy elderly individuals following ingestion of an isocaloric intact whey protein supplement or an essential amino acid supplement is quantified to provide an energetically efficient anabolic stimulus.

TL;DR: The transmembrane amino acid transport rate can be measured in vivo in muscle with a relatively noninvasive technique, and in the dog hindlimb the equilibration between tissue and plasma free amino acid pool is different for each amino acid depending on the kinetics of the trans Membrane transport systems, suggesting that variations in transport rates could play a role in controlling the rate of protein synthesis.

TL;DR: Female burned patients exert an attenuated inflammatory and hypermetabolic response compared with males, which is reflected in improved muscle protein net balance and preservation of lean body mass, which are associated with shortened hospital stay.
