    Sterkowicz test

    Secondary Outcome Measures

    heart rate
    Heart rate will be determined using the Polar H1 (Polar, Kempele, Finland)

    Body weight will be assessed to the nearest 0.002 kg using the WLT 60/120/X/L3 scale (All Scales Europe, Veen, The Netherlands)
    Borg Rating of Perceived Exertion Scale
    The Borg Rating of Perceived Exertion scale is a numerical scale (to determine exertion) that ranges from 6 to 20, where 6 means "no exertion at all" and 20 means "maximal exertion.

    5. Study Description

    Brief 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.
