PENGARUH REHIDRASI DENGAN MINUMAN ISOTONIK TERHADAP ATENSI (Studi Perbandingan dengan Air Mineral)

Abstract

Background: Attention is an act of applying mind to an object, in clear and vivid form, to deal with said object. There are three aspects of attention: alerting, orienting, and executive attention. Dehydration about 1-2% of body weight can impair cognitive function, attention is a case in point. Adequate rehydration is needed to prevent further effect of dehydration. One of the rehydration efforts is by drinking sports drink. Objective: To investigate the effect of rehydration using sports drink on attention. Method: This was true experimental research and the samples were students of Faculty of Medicine, Diponegoro University (n=31). The samples were randomly assigned into one of three groups: sports drink, mineral water, and without rehydration. The samples ran for 5 kilometers in 45 minutes to induce dehydration. The attention was measured using Attention Network Test software before being dehydrated, after being dehydrated and after being rehydrated. Results: There were improvement in alerting function in sports drink group from 64,20 ± 47,11 ms to 29,20 ± 20,92 ms with p = 0,005 and improvement in orienting function in mineral water group from 59,10 ± 36,71 ms to 36,80 ± 22,17 ms with p = 0,036. There was significant difference on alerting function after being rehydrated between sports drink and mineral water group with p = 0,025. Conclusion: Rehydration with sports drink improves alerting function and rehydration with mineral water improves orienting function. Rehydration with sports drink improves alerting function better than mineral water. Keywords: Rehydration, Sports Drink, Dehydration, Attention, Attention Network Test
