Brief Summary
In crossover trials, ten (N=10) young men (18-35 y) will receive stable isotope tracer infusions and perform a single bout of resistance exercise. Immediately after resistance exercise, participants will ingest stable isotope labeled whole eggs (18 g protein, 17 g fat) or egg whites (18 g protein, 0 g fat) cooked in scrambled form. Repeated blood and muscle biopsies will be collected to determine whole body amino acid kinetics, muscle amino acid transporters, anabolic signaling and myofibrillar protein synthesis rates during the trials.

Outcome Measures
Primary Outcomes (1)
Fractional synthetic rate of myofibrillar proteins to whole egg and egg white ingestion
Myofibrillar protein synthesis rates will be assessed during the postabsorptive period for 3 hr and during the 5 hr after the ingestion of the experimental beverages. This will allow us to assess the change from the postabsorptive to the postprandial period
Postabsorptive for 3 hours, Postprandial for 5 hours
Secondary Outcomes (2)
Phosphorylation of muscle anabolic signaling
Baseline and at 2 and 5 hours after protein ingestion
Exogenous rate of leucine appearance after ingestion of whole eggs and egg whites.
5 hour postprandial phase
Study Arms (2)
Whole eggs
ACTIVE COMPARATORAfter resistance exercise, participants will ingest whole eggs (18 g protein, 17 g fat) cooked in scrambled form.
Egg Whites
EXPERIMENTALAfter resistance exercise, participants will ingest egg whites (18 g protein, 0 g fat) cooked in scrambled form.
Interventions
Participants will perform leg extension and leg press immediately prior to ingestion of whole eggs or egg whites
Participants will ingestion whole eggs immediately after resistance exercise
Participants will ingestion whole eggs immediately after resistance exercise
