Abstract The purpose of this experiment was to determine whether sugar or caffeine best improved reaction time. 30 subjects took a reaction test after consuming either water, Gatorade, or Redbull. The 10 subjects who consumed Redbull had the worst average reaction time. The 10 subjects who consumed Gatorade had the best average reaction time. Based on this experiment, sugar is the stimulant which is best for reaction time.
