Influence de stratégies nutritionnelles sur le fonctionnent cognitif au cours d’une sollicitation physiologique

Abstract : In sport and exercise activities, successful performances strongly depend on the ability to simultaneously carry out cognitive and physical demands. More precisely, it would seem that performance is frequently influenced by the efficacy of decision-making realized under strong temporal pressure. The aim of this thesis work is to assess the effect of nutritional supplements that is carbohydrate, caffeine and guarana on cognitive functions during an acute exercise. Overall, our results suggest that ingestion of these three supplements enhance speed of information processing during a decision-making task at the end of exercise. Additionally, caffeine mouth rinsing seems worthwhile since a likely enhancement of inhibition processes has been reported after use during exercise. Finally, a decrease of perceived exertion has been reported with caffeine and guarana ingestion along with carbohydrate mouth rinsing. In conclusion, our results indicate the potentiation of exercise effects on cognitive function. Furthermore, they suggest nutritional supplements could enhance cognitive processes during exercise in what may be a predictive factor of performance enhancement.
