Outline of Final Research Achievements

The aim of this research is to examine the impact of body water loss on service accuracy and the factors contributing to performance degradation due to body water loss. No significant differences were observed in the rate of change in service accuracy under the various conditions. A significant difference was noted in the rate of change in grip strength (right hand) between the 0% water loss condition and the 2% water loss condition (p < 0.05), but no differences were found under other conditions. The response rate and response time in the Franker task showed no significant differences. Additionally, no significant correlation was found between the rate of change in service accuracy and the rates of change in muscle strength and executive function.
