Gastrointestinal symptoms and nutritional intake among participants in a non-professional cycling event.

ABSTRACT

PURPOSE: To determine the occurrence of gastrointestinal (GI) symptoms in different settings among cyclists participating in a non-professional cycling event. The nutritional intake during the event and the association between GI symptoms and both nutritional and non-nutritional factors were also analyzed. METHODS: A descriptive correlational study was performed among participants in the 2023 'Mallorca 312-Milestone Series' cycling event. A pre-race questionnaire was completed by 247 participants (37 women) while a post-race questionnaire was completed by 138 participants (24 women). RESULTS: The prevalence of GI symptoms in training sessions and in previous cycling events were 22-26%. GI complaints during the race were reported by 38.4% of participants. GI symptoms during training (p = 0.003), in previous cycling events (p = 0.012) and in the Mallorca 312 event (during p = 0.010; after p = 0.014) were associated with rest GI symptoms. Furthermore, GI symptoms during the Mallorca 312 event were associated with an immediately previous more nervous feeling (p = 0.016). Participants with shorter previous experience in similar events reported a more nervous feeling (p = 0.023). On average, participants in the Mallorca 312 achieved the recommended carbohydrate intake (59.2 g/h; recommended 30-60 g/h) and the fluid intake (500 ml; recommended 400-800 ml/h) rates. No association was found between GI symptoms and nutritional parameters or food intake. CONCLUSION: GI symptoms at rest could be considered the main factor associated with GI symptoms in cyclists. GI symptoms during the event were also associated with a more nervous feeling, which could be explained, at least in part, by shorter previous experience.
