Clinical Trial Summary

Dehydration is a common phenomenon in judo that can lead to negative performance such as a decline in strength, a decline in anaerobic performance, a reduced body fluid balance, glycogen depletion and worsened psychological parameters. Therefore, we want to simulate several judo combats and look at the performances whether they change during a competition day. We also want to see if the results are different in a dehydrated versus euhydrated state.
