Abstract

Background: Reaction time is one of many physiological parameters which has an important role in daily activity. Being dehydrated by just 1-2% body mass loss impairs performance and reduces reaction time. Adequate rehydration is often suggested to prevent severe dehydration. One of many rehydration efforts is by consuming sports drinks. Aim: To investigate the effect of rehydration with sports drinks on reaction time. Methods: This research was true experimental study using 31 students of medical faculty Diponegoro University (22 men and 9 women) between the ages of 18 and 24 as research subjects. Their reaction time were measured by Attentional Network Test (ANT) before dehydration, after dehydration and after rehydration. Subjects were randomly assigned to one of three rehydration groups: sports drinks, mineral water and without rehydration. The methodology to induce dehydration is a total of 5 km of running within 45 minutes. Results: Friedman test was observed there is mean reaction time reduction on subjects with sports drink rehydration (p=0,002). Significant difference in mean reaction time on subjects with sports drinks rehydration was noted at before dehydrated condition to after rehydrated condition (p=0,005). Meanwhile, there is no significant difference in mean reaction time between after dehydrated condition and after rehydrated condition on subjects with sports drinks rehydration (p=0,059). Kruskal-Wallis test showed no significant differences in mean reaction time after rehydration among three groups: sports drinks, mineral water and without rehydration (p=0,593). Conclusions: There was no signicant reaction time difference before and after rehydration with sports drinks or mineral water. Keywords: Reaction time, sports drinks, dehydration, rehydration
