Introduction: Carbohydrates play an important role in human performance. Pre-exercise carbohydrates may have an ergogenic effect in intermitted-based exercise. Objectives: The objectives of the study were to 1) determine if pre-exercise carbohydrate supplementation improves the number of bouts completed by the participants, 2) examine the effects of pre-exercise carbohydrate supplementation on intermittent critical velocity (ICV), 3) examine if pre-exercise carbohydrate supplementation increases anaerobic running capacity (ARC), and 4) determine if pre-exercise carbohydrates improve critical rest intervals (CRI). Methods: Participants (n=13) completed an initial assessment of a graded exercise test (GXT) to measure peak velocity. This velocity was then used to determine velocities for the ICV test protocol. In the ICV test protocol, participants sprint at an equal work-to-rest ratio of 15 seconds at intensities of 130%, 110%, and 120% of their peak velocity until failure. A 15-minute rest period separated each intensity. Each participant completed the protocol twice, while consuming carbohydrates prior to one of the trials. Blood glucose, blood lactate, perceived recovery status (PRS), and session-ratings of perceived exertion (S-RPE) were measured and recorded periodically during testing. Results: Using repeated measures analysis of variance, differences between the baseline and intervention trials regarding ICV, ARC, and CRI were not statistically significant (p=0.823, p=0.653, p=0.778, respectively). However, increases were seen between total distance, time to exhaustion, and number of bouts completed. Discussion: Increases seen in base measures (distance, time, bouts) are indicative of the ergogenic of pre-exercise carbohydrate supplementation.
