Abstract
Aim: One of the methods used to improve sports performance is the use of carbohydrate mouth rinse. The purpose of this study is to investigate the effect of carbohydrate mouth rinse on the specific performance of trained soccer players.

Methods: Eighteen professional football players (22 ± 2 years) were randomized into two groups of carbohydrate mouth rinse (CMR) and placebo (P) in a fasted state after eight hours of sleep. During the two main test sessions, players were provided with either a color- and flavor-matched carbohydrate drink or a no-calorie drink (placebo) for a mouth rinse in a double-blind randomized crossover design. Players were asked to rinse the carbohydrate solution in their mouth for 10-15 seconds and then return it to the plastic cup. Sprint performance, maximum height jump, and 30-15 intermittent fitness test (30-15 IFT) were taken from the subjects.

Findings: Carbohydrate mouth rinse increased running distance in 15-30 IFT test. While there was no significant difference between the two groups in the performance of the 30-meter speed test and the maximum vertical jump.

Conclusion: Therefore, those soccer players who are unable to drink carbohydrate solutions due to digestive problems are advised to use the carbohydrate mouth rinse way to improve their performance during the game.
