Efeitos do enxágue bucal com carboidratos e distúrbios gastrointestinais em triatletas
Resumo
A ingestão de carboidratos se configura como uma interessante estratégia ergogênica, durante esforços de longa duração, como o Triatlon. Entretanto, desconfortos gastrointestinais são bastante comuns ao se realizar essa prática, o que pode comprometer o desempenho do atleta. O enxágue bucal com carboidratos, seguido do descarte (cuspida) da solução, pode ser uma estratégia para manutenção do desempenho, sem a ocorrência de efeitos colaterais. Dessa maneira, o objetivo do presente estudo foi verificar possíveis efeitos colaterais do enxágue bucal com carboidrato, no ciclismo, em atletas de triathlon. Doze homens, triatletas treinados, foram submetidos a 2 situações experimentais, nas quais eles deveriam completar 1,5 km de natação, seguidos de 40 km de ciclismo, com o menor tempo possível e intensidade autorregulada (teste contrarrelógio). Ao longo do ciclismo, de forma cega e cruzada, os voluntários enxaguaram a boca com um bolus de 25 ml de solução placebo 0% de CHO ou solução com 16% de CHO (maltodextrina), a cada 12,5% da distância a ser percorrida. Um questionário de sintomas gastrointestinais foi respondido ao final dos 40 km de ciclismo. Apenas 1 voluntário (8,33%) relatou desconforto, enquanto 91,66% não apresentaram nenhum tipo de sintomas no protocolo de enxágue com CHO. Portanto, no presente estudo, o enxágue bucal com carboidrato não apresentou efeitos colaterais gastrointestinais quando utilizado durante esforço de longa duração.
