Oral Communications 4: Clinical nutrition and metabolismOP026: Intensive Exercise Hampers the Postprandial Citrulline Bioavailability Following Casein Bolus Feeding

Rationale: Metabolic stress like surgery and intensive exercise have been reported to increase intestinal permeability. It is not known whether intensive exercise also influences gut metabolic functioning. The effects of intensive exercise on intestinal permeability, postprandial amino acid (AA) bioavailability and intestinal enterocyte metabolic mass were determined in the human intervention study Protege.
