Abstarct: The purpose of this study was to compare the effects of rehydration with milk, glycerol solution and simple water on the performance and selected physiological factors of wrestlers 16 hours after acute dehydration. The Research was a quasi-experimental study. Among students who had a history of participating in the wrestling exercise and dehydration in the sauna, 24 wrestlers were selected voluntarily and were randomly devided into three groups: water (control), milk and glycerol solution. The three groups have carried out these steps: Pre-test includes: weighing, measuring body composition, blood samples and wrestling performance test PWPT. After the first test, including acute dehydration in the sauna at a rate of 3% of body weight, a pre-test measurements were repeated. Immediately after the end of this step to 16 hours later, subjects consumed one of three solutions, after the second test that was similar to the previous step. Data analyzed using the Kolmogorov-smirnov, ANOVA and repeated measures at a significance level of P<0.05. The results showed that acute dehydration caused the reduction in time wrestling performance test PWPT and the percentage of plasma volume, but rehydration with solutions of milk, glycerol and water failed to cause a significant statistical difference among groups. The percentage of water return showed no significant difference among groups, and the Maintain of body after 16 hours of rehydration had no significant difference among groups. According to the findings, it can be said that milk and glycerol solution for 16 hours weighing until the start of race, are not proper rehydration solutions And they can not return some physiological and performance capacities of wrestlers to the level before the acute dehydration. However, more research is needed in this field.
