Esophageal reflux in conditioned runners, cyclists, and weightlifters
Abstract
Introduction Gastroesophageal reflux disease is a disorder in which gastric contents move from stomach to esophagus. Exercise is a recognized contributing factor to reflux in healthy volunteers and is reported to be proportional to exercise intensity and the type of exercise. Our aim was to explore changes in physiology occurring in conditioned runners, cyclists, and weightlifters. Methods Ten subjects from each sport with >3-month history of exercise-induced heartburn were enrolled. Subjects underwent evaluation of fasting and fed esophageal pH, heart rate, GI symptom, and perceived exertion during standardized exercise routines at 65% (60 min) and 85% (20 min) of their maximal capabilities. Results Weightlifters experienced the most heartburn and reflux: 18.51 +/- 17.34% time esophageal pH Conclusion Our study demonstrates that strenuous exercise induces significant reflux and related symptoms in conditioned athletes.

The direct correlation between exercise and a decrease in intra-esophageal pH, as well as acid reflux disease and an increased risk of AF, has been shown in many observational studies in elite athletes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
