Primary Outcome Measures:
  • Muscle protein fractional synthetic rate following protein ingestion [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    The ability of the muscle to synthesise new proteins will be assessed over a 3 h period following protein ingestion and will be compared between groups. This only occurs on one occasion.

Estimated Enrollment: 28
