Independently, carbohydrate and caffeine mouth rinsing can improve varying types of performance, but studies have yet to examine their combination. PURPOSE: This study investigated the independent and synergistic ability of carbohydrate and caffeine mouth rinsing to improve intermittent running performance. METHODS: The Yo-Yo Intermittent Recovery Test-Level1 (Yo-Yo IRT-1) was completed in ten collegiate (NCAA Division II) male lacrosse players after a 10-second mouth rinse with a solution, randomly assigned, of either 6% carbohydrate (CHO), 1.2% caffeine (Caff), 6% carbohydrate + 1.2% caffeine (CHO+Caff), placebo (H2O) or a no rinse control (CON). On testing days, participants reported to facility. after an overnight fast, in groups of three or four and were lead through a standard warm-up then given their experimental solution immediately followed by their Yo-Yo IRT-1. Rating of Perceived Exertion (RPE) was collected by the Borg Scale at the start of each stage, marked by the audio cues. The total distance ran during the test before termination was the main variable. Participants completed all conditions separated by one week of recovery. A One-way ANOVA was used to determine the impact of the mouth rinses with a p-value of 0.05 to determine statistical significance. RESULTS: No significant improvements in Yo-Yo IRT-1 performance were found between solutions (p > 0.05). Significantly lower RPE (p < 0.05) was reported at the conclusion of stage 11 in the CHO and CHO+Caff when compared to CON. CONCLUSION: Further research is needed to determine if mouth rinsing with carbohydrate, caffeine, or their combination can impact field-based running performance.
