Carbohydrate ingestion during exercise has been extensively investigated to enhance exercise performance, particularly during prolonged exercise (>2 h) when endogenous carbohydrate is limited. The pertinent benefit of carbohydrate ingestion is that it delays the depletion of vital energy source for exercise, hence delaying fatigue. Athletes have often been advised to drink or rehydrate (replace body fluid loss) to ensure sufficient energy source and to avoid dehydration during exercise Nevertheless, the ability for athletes to rehydrate in a real race setting, maybe challenging due to fluid availability and the nature of the event, such as during a running event. As an alternative to drinking, carbohydrate mouth rinsing has resulted in enhanced prolonged exercise performance. The underlying mechanism responsible for this improvement has been associated with the activation of the oral receptor that is related to reward and behavioural centre of the brain that contributed to enhancing exercise performance. Numerous studies have examined factors that influence the effectiveness of carbohydrate mouth rinsing. While these studies have presented convincing evidence to support their hypothesis, future studies are required to provide new insight into the effectiveness of carbohydrate mouth rinsing on exercise performance. These questions include how the environmental condition and dehydration level may influence the effectiveness of carbohydrate mouth rinsing on endurance exercise performance.
