AB  - This study determined the effect of nutritional supplementation throughout 
      endurance exercise on whole-body leucine kinetics (leucine rate of appearance 
      [Ra], oxidation [Ox], and nonoxidative leucine disposal [NOLD]) during recovery. 
      Five trained men underwent a 2-h run at 65% VO(2max), during which a carbohydrate 
      (CHO), mixed protein-carbohydrate (milk), or placebo (PLA) drink was consumed. 
      Leucine kinetics were assessed during recovery using a primed, continuous 
      infusion of 1-13C leucine. Leucine Ra and NOLD were lower for milk than for PLA. 
      Ox was higher after milk-supplemented exercise than after CHO or PLA. Although 
      consuming milk during the run affected whole-body leucine kinetics, the benefits 
      of such a practice for athletes remain unclear. Additional studies are needed to 
      determine whether protein supplementation during exercise can optimize protein 
      utilization during recovery.
