The purpose of this research is to investigate effects of different fluid ingestion on physiological metabolism, reaction time, and breath alcohol concentration after alcohol consumption For this study, seven male college students were divided into three groups as follows; alcohol consumption only (A(, water only (AW), and ion fluid consumption after the reaction time and recovery of breath alcohol concentration in AI(p<0.05). From this research, we could concluded that drinking ion fluid after alcohol consumption might draw positive effects on reaction time and recovery of the breath alcohol concentration. On the basis of these results, it is useful to diminish the concentration of alcohol quickly in the body and keep the body`s balance with ion fluid consumption that contains carbohydrate and electrolyte.
