Objective: To examine the effect of a sports drink during strenuous exercise on duodenal motility and gastrointestinal symptoms. Methods: In a cross-over design, 7 male triathletes performed two 170-min run-bike-run tests at about 70% peak oxygen uptake (O<sub>2peak</sub>), with either a 7% carbohydrate (CHO) sports drink or tap water. Antroduodenal motility (phase III of the migrating motor complex; MMC) was measured with an ambulant manometry system.
