Gastrointestinal symptoms during exercise in Enduro athletes: prevalence and speculations on the aetiology.

Abstract

A study of the prevalence of gastrointestinal symptoms during exercise was carried out on athletes who participated in the recent Enduro event in Dunedin. Of 119 competitors, 70 (59%) responded to our questionnaire and demonstrated a prevalence of gastrointestinal symptoms of 81%. Upper gastrointestinal symptoms were noticed in 58% with lower gastrointestinal symptoms, tending to be more severe and significant to the athlete, noticed in 61%. Speculations on the aetiology of these symptoms are included. The demonstrated high prevalence of symptoms during exercise and the relative lack of knowledge in this area provides a fertile ground for further objective research.
