Efeito do enxágüe bucal de cafeína isolada ou combinada com carboidrato em testes submáximos até exaustão

Abstract

Over the years, several research centers have been dedicated to investigate strategies to promote improvements in performance, whether through models of physical training and / or nutritional counseling. Among nutritional interventions stand out studies related to carbohydrate (CHO) and caffeine (CAF). The benefits provided by the use of CHO become evident in various types of tests, ranging from trials with a constant intensity, to simulation tests against time. In addition to the types of tests, the intensity does not appear to be a limiting factor for the effects of CHO, as their benefits are well documented in intermittent tests, short, médium and long term. As well as CHO, possible effects from the use of the CAF have also been extensively investigated. Its effects are also observed in various types of tests, whether of low or high intensity. But the effects from the combination of carbohydrates plus caffeine (CAF + CHO) and possible mechanisms of action require further elucidation. Therefore, these dissertation objectives were: 1°) review the main studies that investigated the effects of combination CAF + CHO over the years; 2°) Analyze whether the rinse with CAF can improve performance in subjects who perform submaximal tests and 3°) see if caffeine can enhance the effects of rinsing with CHO acting in combination. In the analysis of review articles, it was observed that most studies show a performance improvement by combining CAF + CHO, however, possible mechanisms to promote these results are not yet fully clarified. In the results article, rinsing with CAF was more effective than the placebo rinse, but the CHO + CAF combination did not potentiate the effects isolated CHO or CAF.
