TI  - Muscle glycogen storage postexercise: effect of mode of carbohydrate 
      administration.
PG  - 720-6
AB  - The primary purpose of this study was to determine whether gastric emptying 
      limits the rate of muscle glycogen storage during the initial 4 h after exercise 
      when a carbohydrate supplement is provided. A secondary purpose was to determine 
      whether liquid (L) and solid (S) carbohydrate (CHO) feedings result in different 
      rates of muscle glycogen storage after exercise. Eight subjects cycled for 2 h on 
      three separate occasions to deplete their muscle glycogen stores. After each 
      exercise bout they received 3 g CHO/kg body wt in L (50% glucose polymer) or S 
      (rice/banana cake) form or by intravenous infusion (I; 20% sterile glucose). The 
      L and S supplements were divided into two equal doses and administered 
      immediately after and 120 min after exercise, whereas the I supplement was 
      administered continuously during the first 235 min of the 240-min recovery 
      period. Blood samples were drawn from an antecubital vein before exercise, during 
      exercise, and throughout recovery. Muscle biopsies were taken from the vastus 
      lateralis immediately after and 120 and 240 min after exercise. Blood glucose and 
      insulin declined during exercise and increased significantly above preexercise 
      levels during recovery in all treatments. The increase in blood glucose during 
      the I treatment, however, was three times greater than during the L or S 
      treatments. The average insulin response of the L treatment (61.7 +/- 4.9 
      microU/ml) was significantly greater than that of the S treatment (47.5 +/- 4.2 
      microU/ml) but not that of the I (55.3 +/- 4.5 microU/ml) treatment.(ABSTRACT
