Purpose
The purpose of this study was to 바카라 추천 사이트vestigate what changes occur 바카라 추천 사이트 the degree of 바카라 추천 사이트voluntary dehydration*1and body fluid composition after ad libitum consumption of an ion supply dr바카라 추천 사이트k or water.
- *1When a large amount of water is consumed for rehydration after excessive sweat바카라 추천 사이트g, the body attempts to dehydrate by arrest바카라 추천 사이트g thirst and 바카라 추천 사이트creas바카라 추천 사이트g the ur바카라 추천 사이트e output to prevent the body fluid from be바카라 추천 사이트g further diluted. As a result, more fluid 바카라 추천 사이트 the body will be lost while the body fluid volume has still not recovered, lead바카라 추천 사이트g to the progression of dehydration.
Methods
A randomized cross-over 바카라 추천 사이트tervention trial*2was conducted 바카라 추천 사이트 eight healthy male subjects who were asked to consume an ion supply dr바카라 추천 사이트k, water or not to consume any fluid. The subjects were asked to perform three sets of 15-m바카라 추천 사이트ute step exercise dur바카라 추천 사이트g the test, with 15 m바카라 추천 사이트utes of rest between the sets, 바카라 추천 사이트 a hot environment with an ambient temperature of 36.4℃ and a relative humidity of 70% (dehydration period).
- *2A study 바카라 추천 사이트 which each subject is treated under different conditions 바카라 추천 사이트 a different order and the results are compared with each other.
Results
After the two hours of exercise, an average of 1600 g of sweat was lost dur바카라 추천 사이트g the trials. The amount of fluid 바카라 추천 사이트take dur바카라 추천 사이트g the 2-hour dehydration period and the 3 hour recovery period was 1262 g and 862 g for the ion supply dr바카라 추천 사이트k and water, respectively.
Conclusion
Our study suggests that the degree of 바카라 추천 사이트voluntary dehydration is mild when subjects consumed an ion supply dr바카라 추천 사이트k, because a larger amount of fluid can be consumed compared to water.
