The Effect of Rehydration with Variation Fluid Temperature on Hydration Status Among Football Athletes

摘要

Increase body temperature during exercise especially in the hot environment can lead to dehydration, so it was needed fluid regulation. The purpose was to know the effect of rehydration with variation fluid temperature on hydration status in among athletes. Quasi experimental study in 30 male football athletes aged 14-18 years old. Subjects were divided into 3 groups based on variations of rehydration fluid temperature, ie cold (T1) 10°-16°C, normal (T2) 2°~0-26°C, warm (T3) 40°-48°C. Subjects were given 1400 ml rehydration fluids during the exercise period. The activity that was given was the football game with 90 minutes duration. Data collected were fluid intake 24 hours before exercise, body weight and urine specific gravity (USG) before and 60 minutes after exercise. Bivariate analysis used One-way ANOVA and Kruskall Wallis Test. Subjects had minimal dehydration (73,3%) before exercise based on the USG values and all subjects in all three groups were dehydrated after exercise (p<0.05). There were significant difference of status hydration in athletes on indicator percent body weight changes and USG after intervention (p<0.05). The most significant difference was in T1 Vs T3 group. Conclusion: Rehydration fluid with temperature of 10°-16°C proved to effect the percent body weight change and USG changes that was lower than the rehydration fluid with temperature of 20°-26°C and 40°-48°C.
