What performance improvement can a mouth rinse provide?

A mouth rinse can enhance performance by providing a moderate improvement in endurance and exercise performance, particularly during high-intensity activities. Research indicates that utilizing a carbohydrate mouth rinse can result in a 2-3% improvement in performance. This improvement is attributed to the brain's perception of the sweet taste stimulating a reward mechanism, potentially enhancing endurance and reducing fatigue during prolonged exercise.

The 1-2% improvement option may be too conservative, as studies generally report a slightly higher range. The 3-4% and 5-6% options might overstate the benefits, as performance improvements are typically measured within the lower boundaries acknowledged in the literature. Therefore, the 2-3% improvement aligns most closely with current research findings on mouth rinses in sports performance contexts.
