TI  - Effects of postexercise carbohydrate-protein feedings on muscle glycogen 
      restoration.
PG  - 1976-82
AB  - The purpose of this investigation was to determine the effects of postexercise 
      eucaloric carbohydrate-protein feedings on muscle glycogen restoration after an 
      exhaustive cycle ergometer exercise bout. Seven male collegiate cyclists [age = 
      25.6 +/- 1.3 yr, height = 180.9 +/- 3.2 cm, wt = 75.4 +/- 4.0 kg, peak oxygen 
      uptake (VO(2 peak)) = 4.20 +/- 0.2 l/min] performed three trials, each separated 
      by 1 wk: 1) 100% alpha-D-glucose [carbohydrate (CHO)], 2) 70% carbohydrate-20% 
      protein (PRO)-10% fat, and 3) 86% carbohydrate-14% amino acid (AA). All feedings 
      were eucaloric, based on 1.0 g. kg body wt(-1). h(-1) of CHO, and administered 
      every 30 min during a 4-h muscle glycogen restoration period in an 18% wt/vol 
      solution. Muscle biopsies were obtained immediately and 4 h after exercise. Blood 
      samples were drawn immediately after the exercise bout and every 0.5 h for 4 h 
      during the restoration period. Increases in muscle glycogen concentrations for 
      the three feedings (CHO, CHO-PRO, CHO-AA) were 118 mmol/kg dry wt; however, no 
      differences among the feedings were apparent. The serum glucose and insulin 
      responses did not differ throughout the restoration period among the three 
      feedings. These results suggest that muscle glycogen restoration does not appear 
      to be enhanced with the addition of proteins or amino acids to an eucaloric CHO 
      feeding after exhaustive cycle exercise.
