Abstract

L-citrulline is an amino acid that is naturally produced in the human body and can be consumed within the human diet. It can be utilized in the process to form nitric oxide, a vasodilator, which causes an increase in blood flow and oxygen delivery to the active muscles. For this reason, L-citrulline has been utilized as an ergogenic aid to improve athletic performance. The purpose of this single blind randomized crossover study was to determine if L-citrulline supplementation has an effect on power output, fatigue rate, and recovery rate during high intensity interval exercise. Regularly active subjects completed two trials, one with 5 grams of L-citrulline supplement in flavored water and the second with a placebo of flavored water. Following ingestion and a 30 min digestion period, subjects completed a series of 3 Wingate anaerobic cycling tests separated by 4 min active recovery bouts. Peak power and fatigue rate were determined following each Wingate. Recovery rate was monitored by documenting heart rate and RPE throughout the Wingate and recovery period. Results are pending following the completion of data collection. Existing human-based research has demonstrated an ergogenic effect of L-citrulline in anaerobic performance however the potential benefits are still not clear.
