Introdução: O impacto de exercício físico no trato gastrointestinal (GI) é uma área de interesse emergente. São indiscutíveis os benefícios para a saúde associados à prática de exercício físico. Muitos são os estudos que indicam a existência de uma relação inversamente proporcional entre o exercício físico e risco de doenças do trato GI. No entanto, apesar dos benefícios já cientificamente demonstrados, a literatura mostra também uma associação importante entre a prática de exercício físico e sintomas GI (náuseas, vómitos, refluxo gastro esofágico (GE), diarreia e hemorragia GI).
Objetivos: Estudar a relação entre a ingestão alimentar e a presença de sintomas GI em indivíduos praticantes de exercício físico.
Material e métodos: A recolha de dados foi feita com recurso a um questionário aplicado a indivíduos adultos praticantes de exercício físico. Este avaliou: estado nutricional, ingestão alimentar, exercício físico (versão curta International Physical Activity Questionnaire), sintomas GI (Gastrointestinal Symptom Rating Scale) e intolerância à lactose (IL).
Resultados: Os sintomas GI afetam cerca de um terço da amostra deste estudo (n=26; 32,5%), um número inferior são afetados por IL (n=21; 26,3%). A ingestão de suplementos estava associada à presença de sintomas severos de dores abdominais. Também aqueles que apresentavam sintomas mais graves de diarreia apresentavam os valores mais elevados de massa isenta de gordura (%) e maior prática de exercício físico (> a 1 ano). Os indivíduos com diagnóstico por questionário de IL apresentaram sintomatologia mais grave de dor abdominal.
Conclusão: Existe uma associação entre a ingestão alimentar, sintomas GI e EF amador. Dor abdominal, refluxo GE, obstipação e diarreia foram apontados como sintomas presentes, tendo o último sido o mais relevante. O estado nutricional, tempo e tipo de EF mostraram estar relacionados com a ingestão alimentar. Mostra-se essencial uma prescrição alimentar de acordo com a prática de EF e consequências GI.
Introduction: The impact of physical activity in the gastrointestinal tract (GI) is an emerging area of interest. The health benefits associated with physical activity are indisputable. Many studies have indicated the existence of an inverse relationship between physical activity and risk of GI tract diseases. However, despite the benefits scientifically demonstrated, the literature also shows a significant association between physical exercise and GI symptoms (nausea, vomiting, gastro esophageal reflux (GE), diarrhea and GI bleeding). Objectives: To study the relationship between food intake and the presence of GI symptoms in individuals practicing physical exercise. Methods: Data collection was done using a questionnaire in adults practicing physical exercise. This evaluated: nutritional status, food intake, exercise (short version International Physical Activity Questionnaire), GI symptoms (Gastrointestinal Symptom Rating Scale) and lactose intolerance (IL). Results: The GI symptoms affected about one-third of our sample (n = 26; 32.5%), fewer are affected by IL (n = 21; 26.3%). The intake of supplements was associated with the presence of severe abdominal pain symptoms. Also, those with more severe diarrhea symptoms had the highest values of fat-free mass (%) and greater physical activity (> 1 year). Individuals diagnosed with IL through questionnaire had more severe symptoms of abdominal pain. Conclusion: There is an association between food intake, GI symptoms and amateur exercise. Abdominal pain, GE reflux, constipation and diarrhea were identified as symptoms, the latest being the most relevant. Nutritional status, time and type of exercise were related to food intake. A diet prescription, according to the practice of exercise and GI consequences, is essential.
