Carbohydrate Mouth Rinsing and Cognitive Response During Exercise

This study investigates whether rinsing the mouth with a carbohydrate solution can improve brain oxygenation and cognitive function during high-intensity exercise. Eleven trained cyclists participated in multiple exercise sessions under different mouth rinse conditions. Brain oxygenation, perceived exertion, and cognitive performance were measured. The goal is to understand if this simple technique can support both physical and mental performance during demanding exercise.
