BECKERS, E. J., N. J. REHRER, W. H. M. SARIS, F. BROUNS, F. TEN HOOR, and A. D. M. KESTER. Daily variation in gastric emptying when using the double sampling technique. Med. Sci. Sports Exerc., Vol. 23, No. 10, pp. 1210–1212. The purpose of this study was to establish the intra-individual variation in the rate of gastric emptying (GE) by using the double sampling technique of George. Eight healthy male volunteers, all familiar with gastric intubation and testing, participated in four GE tests, using an isotonic fluid as a test meal. Conditions were kept constant during all four tests, and each test was separated by at least 48 h. The within-subjects coefficient of variation proved to be 29%. The findings demonstrate that, given standard conditions, GE is reproducible from day to day. |
