Studies have shown that the mere presence of carbohydrate in the human mouth promotes the activation of some specific brain regions, with a positive i mpact on physical performance. Thus, the strategy of carbohydrate mouth rinse has been recently adopted with success in strenuous exercise (> 70% VO2max) lasting approximately 60 min. In this respect, the objective of this study was to discuss, based on literature data, the efficacy of this strategy to improve physical performance, as well as the possible mechanisms involved. The results produced, although still preliminary, are promising and led us to believe that carbohydrate mouth rinse is an interesting strategy, especially because of its easy application, low cost and good efficacy in improving physical performance during intense and prolonged physical exercise

The article presents a study which examines the use of the strategy of carbohydrate mouth rinse in strenuous exercise lasting about 50 minutes. The study explores the potential mechanisms involved in the strategy, and evaluates its efficacy in improving physical performance. The results of the study reveal that the strategy is easy to apply, inexpensive and effective in enhancing physical performance during intense and prolonged exercise.
