Introduction: Carbohydrate (CHO) mouth rinse improves exercise lasting ≤1 h, whereas caffeine (CAF) mouth
rinse increases the performance of repeated bouts of short duration, high-intensity cycling. Limited research is currently available regarding the effects of a combined CHO and CAF mouth rinse on repeated sprint and skill patterns in team sports. This study examined the effect of a CHO and CAF mouth rinse on sprint running and football skill performance. Methods: Twenty-four male collegiate football and futsal players participated in a counterbalanced, double-blinded study where they completed 45 min of the Loughborough Intermittent Shuttle Test (LIST) on four occasions separated by at least 1 wk. Participants rinsed and expectorated 25 ml of 6.4% maltodextrin (CHO), 1.2% CAF, 6.4% maltodextrin combined with 1.2% CAF (CHO+CAF), or placebo for 10 s every 5 min after completing the LIST. Then, they performed repeated sprint ability, the Loughborough Soccer Passing Test, and Loughborough Soccer Shooting Test. Results: There was no significant improvement in the average (p=0.759) or fastest sprint times (p=0.916). There were no significant differences in the passing time (p=0.756), shooting time (p=0.579), and points scored per shot (p=0.500). There were also no significant
differences in heart rate and rating of perceived exertion between the solutions. Conclusion: The CHO and/or
CAF mouth rinse did not improve football performance including sprint running, passing, shooting, and scoring after 45 -min of intermittent exercise in collegiate male athletes.
