Abstract

Using a driving simulator, the effects of an energy drink (ED) with 65g sugars was compared with 380ml of similar drinks, one being sugar free, and the other having an intermediate sugar content (30g). Drinks were given randomly, double blind on separate occasions in a repeated design, to eight young adult sleepy male drivers, just prior to a two-hour afternoon drive on a full-size car simulator under motorway conditions. Lane drifting, subjective sleepiness and electroencephalogram data were obtained. There were non-significant trends for the ED to reduce all three measures of sleepiness when compared with the other conditions, especially in the second hour. However the result of the ED was small in comparison with the 80mg of caffeine found in a cup of coffee, or a functional energy drink having 26gsugar and 80mg caffeine.
