AB  - This study compared the effects of supplementing the normal diets of 8 
      endurance-trained cyclists with additional carbohydrate (CHO), in the form of 
      potato starch, for 3 days on muscle glycogen utilization and performance during a 
      3-hr cycle ride. On two occasions prior to the trial, the subjects ingested in 
      random order either their normal CHO intake of 6.15 +/- 0.23 g/kg body mass/day 
      or a high-CHO diet of 10.52 +/- 0.57 g/kg body mass/day. The trial consisted of 2 
      hr of cycling at approximately 75% of VO2peak with five 60-s sprints at 100% 
      VO2peak at 20-min intervals, followed by a 60-min performance ride. Increasing 
      CHO intake by 72 +/- 9% for 3 days prior to the trial elevated preexercise muscle 
      glycogen contents, improved power output, and extended the distance covered in 1 
      hr. Muscle glycogen contents were similar at the end of the 3-hr trial, 
      indicating a greater utilization of glycogen when subjects were CHO loaded, which 
      may have been responsible for their improved cycling performance.
