Resumo


Introdução: É sabidamente conhecido que o exercício físico promove diversos efeitos benéficos no trato gastrointestinal. No entanto, entre indivíduos que praticam exercícios predominantemente aeróbios e de longa duração, como maratonistas, ciclistas e triatletas, a prevalência de sintomas gastrointestinais é frequente, condição que pode prejudicar o desempenho durante uma prova. Objetivo: avaliar a prevalência de sintomas gastrointestinais durante competição nacional de triathlon. Materiais e Métodos: Participaram do estudo 11 triatletas amadores, de ambos os sexos (33,3 ± 8,5 homens e 25,0% mulheres), idade (33,3 ± 8,5 anos), massa corporal (76,8 ± 9,1kg homens e 60,1 ± 4,4kg mulheres), que responderam ao final da prova um questionário sobre a presença de sintomas do trato gastrointestinal superior e inferior durante a competição. Resultados e Discussão: Das 14 ocorrências relatadas, 78,6% foram referentes ao trato gastrointestinal superior e apenas 21,4% relacionadas a sintomas inferiores. O sintoma de maior prevalência (36,0%) foi a eructação, seguido da dor lateral, que equivaleu a 21,0% da amostra avaliada. Diversos são os fatores etiológicos envolvidos no aparecimento dos sintomas gastrointestinais durante o exercício, como hipoperfusão intestinal, endotoxemia, desidratação, fatores dietéticos e mecânicos, bem como aspectos relacionados ao próprio exercício, os quais possivelmente explicam a prevalência sintomática observada no presente estudo. Conclusão: os triatletas avaliados apresentaram diversos sintomas gastrointestinais, sendo esses predominantemente do trato gastrointestinal superior.

 

ABSTRACT 

Prevalence of gastrointestinal complaints during national triathlon competition

Introduction: It is notoriously known that physical exercise promotes many beneficial effects on the gastrointestinal tract. However, among individuals practicing predominantly aerobic exercises and long-lasting, as runners, cyclists and triathletes, the prevalence of gastrointestinal symptoms is common, a condition that can impair performance during a race. Objective: to evaluate the prevalence of gastrointestinal symptoms during national triathlon competition. Materials and Methods: The study included 11 amateur triathletes, of both sexes (33.3 ± 8.5% men and 25.0 women), age (33.3 ± 8.5 years), body weight (76.8 ± 9.1kg men and 60.1 ± 4.4kg women) who responded to the finish a questionnaire about the presence of symptoms of upper gastrointestinal tract and lower during the competition. Results and Discussion: Of the 14 reported incidents, 78.6% were related to upper gastrointestinal tract and only 21.4% related to lower symptoms. The most prevalent symptom (36.0%) was the belching, followed by lateral pain, which amounted to 21.0% of the sample. There are several etiologic factors involved in the onset of gastrointestinal symptoms during exercise, such as intestinal hypoperfusion endotoxemia, dehydration, diet, mechanical factors, as well as aspects related to the exercise, which possibly explains the symptomatic prevalence observed in this study. Conclusion: the evaluated triathletes had several gastrointestinal symptoms, and those of the upper gastrointestinal tract predominantly.
