Abstract
The aim of the work was to determine the effect of energy drink – Red Bull on the reaction time on the optical stimulus in men. The study group consisted of 10 people aged 25 to 30 years. The reaction time was measured with a reactometer with a measurement accuracy of 1 millisecond. After resting the reaction time averages for 337 ms, a 250 ml Red-Bull dose was administered, and subsequent measurement after 1 hour showed a reduction in the average reaction time to 325 ms (by 12 ms, 3.6 %). Measurements after two hours showed approximately the average same values 325 ms. After administration of 500 ml of Red Bull, the reaction time decreased from a average rest value of 336 ms to aa average value of 325 after one hour (a decrease of 11 ms, 3.3 %). After two hours of exposure to the stimulants in Red-Bull, the reaction time was again maintained the same level an average of 326 ms.
