Abstract: Statement of Problem:The development of fatigue is influenced by simply rinsing the mouth with a carbohydrate solution and is related to telo-anticipation.However, the extent to elicit a strong enough ergogenic response to mitigate fatigue in intense exercise lasting less than 60 minutes is quite limited.Therefore, further investigations are needed to determine an ideal strategy for rinsing carbohydrates to improve short duration and intense exercise performance is needed.Method: Sixteen sprint-trained participants (8=male and 8=female) performed a series of repeated sprint tests under two different conditions in a counterbalanced order; one where they were administered a carbohydrate solution that was rinsed for five seconds and another condition in which the beverage was rinsed incrementally (five, 10, and 15 seconds).Each testing session consisted of three repeated sprint exercise sets (RSE) on a non-motorized treadmill with seven minutes of recovery between sets.Peak speed, average speed, rating of perceived exertion (RPE), perceived recovery status (PRS), perceived activation (FA) were all measured.Approximately 15 minutes following the final sprint, participants provided a session rating of perceived exertion (S-RPE) to rate the global difficulty of the session.Results: Results from the analyses revealed no significant differences between conditions on peak (p = 0.179) or average (p = 0.414) sprint performance.Nor was there any difference between male and female sprint performance.Furthermore, there were no perceptual (PRS, RPE, FA) or metabolic (lactate) differences of fatigue.However, during latter portions of the repeated sprint protocol, average and peak speed of participants showed a trend towards a difference iii between both conditions in repeated sprint set 2 (RSE 2 ) and repeated sprint set 3 (RSE 3 ).The decrements in sprint performance (p = 0.795) and recovery scores (p = 0.847) were not significantly different between CMR conditions.Conclusions: The administration of carbohydrate mouth rinsing (CMR) with increasing duration did not significantly yield improved average or peak sprint performance as compared to rinsing with a consistent duration.More investigations are needed to help further understand the perceptual responses that relate the central and peripheral integration of fatigue with carbohydrate supplementation with repeated sprints.
