PENGARUH PEMBERIAN MINUMAN ISOTONIK TERHADAP MEMORI PADA KEADAAN DEHIDRASI

Abstract

Background: Sport is one of popular activities throughout the world. One of the biggest problems found among athletes in sports is dehydration, which causes many bad health issues for athletes themselves. The bad health issues caused by dehydration, several of them are disturbance and decrease of the memory. Therefore, rehydration is required to overcome the bad effects of dehydration. Aim: To know the effect of rehydration on memory Method: This research uses experimental method. The research subjects are the medical students of Diponegoro University (n=31) whom being dehydrated and rehydrated with isotonic water. Their memories are measured by using code and memory tests. A changing of memories among groups is analyzed with Kruskal Wallis and continued with Mann-Whitney test. Result: It is found that there is a decrease of memories after dehydrating condition rather than before dehydrating condition. Wilcoxon test shows an increase of memory function after rehydration which is significant in group of isotonic water rehydration (p=0,006) and mineral water rehydration (p=0,026).Otherwise, there is a significant ecrease of memory function in group of non-rehydration (p=0,035). Furthermore, the result of Kruskal Wallis shows the significant difference (p=0,022) in memory test among groups. Conclusion: Dehydration decreases memory function, while rehydration with isotonic and mineral water can significantly increase memory function.
