TI  - Carbohydrate-protein complex increases the rate of muscle glycogen storage after 
      exercise.
PG  - 1854-9
AB  - Carbohydrate, protein, and carbohydrate-protein supplements were compared to 
      determine their effects on muscle glycogen storage during recovery from prolonged 
      exhaustive exercise. Nine male subjects cycled for 2 h on three separate 
      occasions to deplete their muscle glycogen stores. Immediately and 2 h after each 
      exercise bout, they ingested 112.0 g carbohydrate (CHO), 40.7 g protein (PRO), or 
      112.0 g carbohydrate and 40.7 g protein (CHO-PRO). Blood samples were drawn 
      before exercise, immediately after exercise, and throughout recovery. Muscle 
      biopsies were taken from the vastus lateralis immediately and 4 h after exercise. 
      During recovery the plasma glucose response of the CHO treatment was 
      significantly greater than that of the CHO-PRO treatment, but the plasma insulin 
      response of the CHO-PRO treatment was significantly greater than that of the CHO 
      treatment. Both the CHO and CHO-PRO treatments produced plasma glucose and 
      insulin responses that were greater than those produced by the PRO treatment (P 
      less than 0.05). The rate of muscle glycogen storage during the CHO-PRO treatment 
      [35.5 +/- 3.3 (SE) mumol.g protein-1.h-1] was significantly faster than during 
      the CHO treatment (25.6 +/- 2.3 mumol.g protein-1.h-1), which was significantly 
      faster than during the PRO treatment (7.6 +/- 1.4 mumol.g protein-1.h-1). The 
      results suggest that postexercise muscle glycogen storage can be enhanced with a 
      carbohydrate-protein supplement as a result of the interaction of carbohydrate 
      and protein on insulin secretion.
