TI  - Gastric emptying and plasma deuterium accumulation following ingestion of water 
      and two carbohydrate-electrolyte beverages.
PG  - 144-53
AB  - The purpose of this study was to compare the gastric emptying rates (GER) of 
      water, a 6% carbohydrate (CHO) beverage, and a 20% CHO beverage and to contrast 
      those rates against the rate at which deuterium oxide in the drinks accumulated 
      in plasma (DAR) following beverage ingestion. Ten subjects (8 males, 2 females) 
      cycled at 60% VO2max for 70 min; at 13 min, the subjects ingested 400 ml of one 
      of the beverages. The GER and DAR of water and 6% CHO were similar, while GER and 
      DAR were both significantly slowed by ingestion of 20% CHO. Although there was a 
      significant correlation (r = .63, p < .05) between GER and DAR, only 40% of the 
      variation in DAR could be accounted for by variation in GER. These data support 
      the contention that DAR is partially determined by GER, with differences in the 
      rate of fluid absorption across the intestine and other factors accounting for 
      the remaining variation in DAR.
