Abstract: The purpose of this study was to determine whether the ingestion of \nan energy-free aspartame beverage (ASP) (99 mg aspartame/L) would \ninfluence endurance performance relative to a water (WAT) trial. Nine \ntrained male cyclists underwent two cycle ergometer trials to exhaustion at \n75% VO2 max. Experimental beverages were ingested every 15 minutes \nbeginning 45 minutes prior to cycling. Mean (? SD) exercise times to \nexhaustion were 100 ? 28 minutes for the ASP trial and 99 ? 34 minutes \nfor the WAT trial (p>.05). Respiratory exchange ratio and heart rate did \nnot differ in response to the treatment condition. Ratings of perceived \nexertion were significantly elevated in the ASP trial but only at the \ninitiation of exercise. It was concluded that the ASP beverage did not \nimpair endurance performance relative to WAT.
