Caffeine And Sports Performance

Research on the physiological effects of caffeine in relation to human sport performance is extensive. In fact, investigations continue to emerge that serve to delineate and expand existing science. Caffeine research in specific areas of interest, such as endurance, strength, team sport, recovery, and hydration is vast and at times, conflicting. Therefore, the intention of this position statement is to summarize and highlight the scientific literature, and effectively guide researchers, practitioners, coaches, and athletes on the most suitable and efficient means to apply caffeine supplementation to mode of exercise, intensity, and duration.

Red Bull® And Reaction Time

In this double-blind study, the effects of consuming a single can (250 ml) of Red Bull®, Sugar Free Red Bull®, or a flavor/appearance-matched placebo on attention and reaction time were measured using a computerized continuous performance task, administered 30 minutes after drink ingestion. No significant differences in continuous performance task performance were related to ingestion of any of the drinks. Effects of Red Bull® or Sugar Free Red Bull® on continuous performance task performance are, therefore, negligible, and are no greater than potential psychomotor enhancements resulting from placebo expectancies.
