The effect of energy drink with caffeine on the change of reaction time on an optical stimulus for men
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.
