Abstract

Introduction: Road crash is one of a global major death contributors including in Malaysia. Road crash are caused by various factors including vehicle defects, human failures, and environment. Human failure is generally related to poor driving performance and drowsiness during driving. In this context, young male adult with average age 19-25 generally involve in road crash. Some studies also found that the consumption of energy drink may lead to reducing of drowsiness as well improve driving performance. Methodology: This was an experimental pre-post study design. A total of 40 male respondents were selected to participate in the study. Respondents were selected according to their Epworth Sleepiness Scale (ESS) score and Body Mass Index (BMI) measurement. They were asked to drive using driving simulators for one hour. Then, take rest for about IS minutes and at the same time they were required to drink 250ml of energy drink. After rest, respondents were asked to continue driving for another 1 hour. To measure drowsiness, lOW A questionnaire had been given for 3 times at different phases which were at pre-driving, after 1 hour driving, and at post driving. Driving performance was measured using special software where it measured Large Speed Variation index (LSV) and Running off Road Index (RORI). Results: The results showed that there was significant association between the consumption of energy drink and reduction in drowsiness among respondents. For LSV index, results also showed that the significant association between the effect of energy drink and LSV index score. However, there was no significant association between energy drink consumption and RORI index score. Conclusion: Energy drink has been proven to reduce drowsiness during prolongs driving. However, energy drink is not much helpful to improve driving performance. Keywords: Energy drink, Drowsiness, Driving Performance
