Effects of carbohydrate mouth rinse on psychophysiological responses, kinematic variables and technical actions during small-sided soccer games

Q: What does this research mean for the field?

Carbohydrate mouth rinse during small-sided soccer games is associated with higher rating of perceived exertion, lower mental fatigue, and selective improvements in technical actions, but has no significant effect on kinematic variables or heart rate. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

To assess the effects of a carbohydrate mouth rinse on psychophysiological responses, kinematic variables, and technical actions during 4-a-side small-sided soccer games.
Evaluated players during 4-a-side small-sided soccer games following a carbohydrate mouth rinse intervention.
Measured psychophysiological parameters (rating of perceived exertion, enjoyment, visual analogue scale for mental fatigue, mood states, and heart rate) and technical actions (passing, tackling, shooting, and interceptions).
Quantified kinematic variables including total distance, high-speed running distance, average metabolic power, high metabolic load distance, sprint distance, accelerations, and decelerations.
Carbohydrate mouth rinse was associated with lower perceived mental fatigue and selective improvements in technical actions.
Players reported a higher rating of perceived exertion during games with the mouth rinse.
Kinematic variables and heart rate showed no statistically significant differences (p > 0.05).
