Introduction: Gastrointestinal (GI) distress in endurance athletes is prevalent and detrimental toperformance. Adverse GI symptomatology can be analogous with irritable bowel syndrome,where fermentable oligosaccharide, disaccharide, monosaccharide and polyols (FODMAP)reduction has demonstrated efficacy. This study investigated the effects of low FODMAP(LFOD) diet on GI distress parameters in runners with a history of non-clinical exerciseassociatedGI symptoms. Methods: Eleven recreationally competitive runners (5 males, 6females; 5km personal best 23:00±4:02 min:sec) participated in the study. Runners wereallocated to a randomized 6-day LFOD or high FODMAP (HFOD) diet separated by a 1-daywash-out in a controlled, single-blinded cross-over study. In each period participants completedtwo strenuous running sessions consisting of 5x1000m and a 7km threshold run. GI symptoms(during-exercise and daily) and the Daily Analysis of Life Demand for Athletes (DALDA)questionnaires were completed. Area under the curve (AUC) was calculated for daily GIsymptoms across each dietary period and analysis was conducted using multilevel mixed-effectslinear regression for comparison between the two diets. Results: A significantly smaller AUCfor daily GI symptoms.6-days-1 during the LFOD compared to HFOD (mean difference -13.4,95% CI [-22, -4.60], P=0.003) was observed. The daily GI symptoms that were significantly lower during LFOD were flatulence (P0.05). Conclusion: Preliminary findings suggest thatshort-term FODMAP reduction may be a beneficial intervention to minimize daily GI symptomsin runners with exercise-related GI distress.
