Abstract: To examine the gastric emptying characteristics of selected test drinks varying in carbohydrate composition and concentration, twenty-five runners ingested 400 ml of a solution in one or more of a series of trials followed by either 15 min seated rest or 15 min running (50 to 70% VO2 max). The solutions tested at rest included water, 5.0% maltodextrin, 3.0% maltodextrin + 2% glucose (MG5.0), and 4.5% maltodextrin + 2.6% fructose (MF7.1). Solutions tested during running included water, MG5.0, MF7.1, 5.5% maltodextrin + 2% glucose, and 5.5% maltodextrin + 2% fructose. At rest and during running, water emptied significantly (P less than 0.5) faster than all other drinks. In the running trials, the volume of gastric residue of 5.5% maltodextrin + 2% fructose (221.7 +/- 11.0 ml) was significantly greater than water (103.4 +/- 19.0 ml), MG5.0 (153.3 +/- 16.8 ml), and MF7.1 (167.3 +/- 14.8), suggesting an inhibitory role of glucose on gastric emptying. Running resulted in a significantly lower volume of gastric residue of water, MG5.0, and MF7.1 (103.4 +/- 19.0, 153.3 +/- 16.8, and 167.3 +/- 14.8 ml, respectively) as compared to the corresponding drinks at rest (209.3 +/- 12.6, 287.7 +/- 16.0, and 271.0 +/- 17.8 ml, respectively). These results suggest a possible advantage for including maltodextrin and fructose as carbohydrate sources in athletic drinks. Furthermore, the rate of gastric emptying is enhanced while running, possibly due to increased mechanical movement of fluid within the stomach.
