The Effects of Dehydration on the Performance of Judoka
A study testing Dehydration in people with Dehydration, run by Vrije Universiteit Brussel.
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. Read more about this study

About this study
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DehydrationOther
Participants will be dehydrated (2% of their body weight) using sauna.
| Study group | Role | What they receive |
|---|---|---|
| dehydrated | Experimental | The participants will be dehydrated (at least 2% of their body weight) before performing the Sterkowicz test. Receives: Other: Dehydration |
| euhydrated | No intervention | The participants will be normally hydrated (= euhydration) before performing the Sterkowicz test (i.e. no specific intervention will be implemented). |
What is being measured
The primary outcome is the main question the study is designed to answer.
Sterkowicz test
Sterkowicz test
Measured: Up to 3 weeks
Secondary outcomes (4)
heart rate
Heart rate will be determined using the Polar H1 (Polar, Kempele, Finland)
Measured: Up to 3 weeks
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)
Measured: Up to 3 weeks
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.
Measured: Up to 3 weeks
body temperature
Body temperature will be determined using the Adtemp 421 Digital Ear Thermometer (American Diagnostics Corporations, Hauppauge, New York, United States of America)
Measured: Up to 3 weeks
