Experimental
No Intervention
Arm Label
dehydrated
euhydrated
Arm Description
The participants will be dehydrated (at least 2% of their body weight) before performing the Sterkowicz test.
The participants will be normally hydrated (= euhydration) before performing the Sterkowicz test (i.e. no specific intervention will be implemented).
Outcomes
Primary Outcome Measures
Sterkowicz test
Sterkowicz test
Secondary Outcome Measures
heart rate
Heart rate will be determined using the Polar H1 (Polar, Kempele, Finland)
Body weight
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.
body temperature
Body temperature will be determined using the Adtemp 421 Digital Ear Thermometer (American Diagnostics Corporations, Hauppauge, New York, United States of America)

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.
