The use of caffeine as a performance-enhancing supplement is on the rise due to caffeine’s known ergogenic effect. Caffeine is often administered as a liquid or in a capsule, but new research has shown that caffeine gum has a faster absorption rate and a higher relative bioavailability. The purpose of this study is to determine if caffeine gum elicits the same ergogenic effect as a liquid or a capsule by examining blood glucose and blood lactate levels during cycling to exhaustion. Eight (n=8) recreationally active males volunteered to participate in the study. Two hundred milligrams of caffeine gum or a placebo was administered 35 minutes prior to exercise, 5 minutes prior to exercise, or 15 minutes into exercise. Participants cycled at 85% of their VO2max until volitional fatigue. Blood glucose and blood lactate were taken via a finger prick immediately upon entering the laboratory, after the first gum administration, and every 10 minutes during exercise. The results indicated that blood glucose (p=.0432) and blood lactate (p=..934) levels over time with the caffeine versus the placebo were not significant. Also, there was no significance in blood glucose (p=.736) or blood lactate (p=.758) levels when comparing the time administered caffeine trials. This was the first exercise study conducted that administered caffeine gum and should be used as a starting point for future research on caffeinated gum and exercise.
