The purpose of this study was to examine the effect of dehydration resulted from exercise on gastric emptying rate (GER) and to investigate the differences between water and 6% glucose solution on GER after dehydration. On separate occasions in randomized order six male college students (26.67 +/- 0.76 yr of age, 78.55 +/- 7.10 kg) exercised for 90 min (or until 2% of initial body weight was lost) on a bicycle ergometer in a warm environment (30 degree C with 30-50% RH). Following exercise, subjects were moved to a neutral environment(18 degrees C with 30-50% RH) and ingested 400ml of water or 6% glucose solution(absorption of water and a 6% glucose solution were compared) Gastric volume were determined prior to each drink and at 15min using modified double sampling technique. Blood sample were taken before and after exercise(pre) and after ingestion of test solution(post). Blood samples were analyzed for percent for change in plasma volume, electrolyte concentration, lactate and glucose concentration. The following observations were made : 1) Dehydration resulted from exercise in a warm environment did not significantly reduce GER. 2) The percentage of ingested test solution emptied from the stomach were significantly less for 6% glucose compared with water. 3) Glucose concentration were significantly higher 6% glucose compared with water while lactate level, osmolality concentration and plama volume were not significantly different from all treatment. 4) The electrolyte results showed no significant differences between the treatment.
