Hydration, beware of overheating


Hydration and overheating

Are you thirsty when you do karate with your teacher?

In clubs, it often happens that we do not drink.

If you can not drink for an hour and a half of intensive exercises, with all due respect to your teacher, for me it's bullshit.
Karate is still sport.
All sports teachers know very well that hydration is essential to be successful.
When I talk about hydrating you, I'm talking about cellular hydration. Having the cells, muscle fibers and tendons well hydrated is very important not to get hurt.
Of course, if your workout does not make you sweat too much, you can spend an hour and a half without drinking. It's not a big deal, but at that point you have to think about it and drink before you come to the club.
I advise you to drink often in small quantities. Drink a glass of water every half hour or even quarter of an hour for two hours before class.
If you drink two or three hours before the class, your body will be well prepared.

Being hydrated for more efficiency

Why is it so important that you get hydrated? You should know that your body contains almost 80% water. You are mainly composed of water. If your body has that much, it's all for something. Besides, he tells you quickly when he is running out of water.
When you are thirsty, you have lost 2% of the volume of water you have in the body.
When you lost those 2% water volume, you lose, at the same time, 20% of your physical abilities. So, that means when you're thirsty, you've lost 20 percent of your potential. That's why I say it's very stupid not to drink in class.

Simply hydrate

I always told my students to bring a bottle of water and just tell them not to put it in the middle of the carpet. They always had something to drink at the edge of the carpet and I did not stop them from drinking as soon as possible. Of course, if we were doing Kihon, they were not going to serve themselves and then drink. They asked me or waited for a part of the course where I gave an explanation that lasted a bit.
When you take a karate class, the teacher and many students like it to be pretty strict. But, to prevent students from drinking, you understood that it was absurd because, when you are thirsty, I repeat, you have 20% less capacity. Your teacher will not manage to make you exceed your limits. So, you do not progress.
To evolve, you must get as close as possible to your limits. Your body must say to itself: "Hola! I will have to rebuild myself but better, so as to exceed my limits. But, if you always work below your capacity because you are always thirsty, the body, what is it? Nothing at all ! It will adapt a little to the fact that you are thirsty, you may be better working while being dehydrated, but it is not good physically.
You, what you want is to increase your abilities. And here you can not do it because you are always working below your full potential.
Drink before, during and after class. You can drink slightly sweet water because it is digested faster. At the osmotic level, it is assimilated much more quickly and it prevents it from remaining in the stomach.

Attention to the accident

Muscle tissues and tendinous tissues are more brittle and less elastic when dehydrated. With your dehydration, you have already lost capacity. If you want to go deep, you force trying and retrying. Result: "crack", you will be a breakdown.
If you are a teacher, I have no order to give you, but try to think about it and have your students drink. The small bottle of water they bring themselves, it avoids the inconvenience of getting everyone out to go drinking.

Finally, I ask you to test and let me know if you feel any difference in being hydrated or dehydrated during your classes.
Share this article with as many people as possible (anyone who is thirsty ... to learn.)
You certainly have karatekas friends or even who do other sports. They will surely be interested in cellular hydration.
Give them the link to this article and suggest that your teacher read it if it prevents you from drinking in class.

I have prepared a video in which I tell you about the benefits of hydration:

I hope these tips will help you enjoy your club lessons even more.
As usual, I will be happy to read your comments and answer you.

See you soon

"How to succeed your grade passes"


  1. Hello
    I'm going to have 72 years old. Several decades ago I had the honor, the pleasure and the joy of having as teacher for years Me KASE. We never get hydrated during classes which, however, were not "salon karate". Drinking a lot of water does not mean that one hydrates one's cells !! To properly hydrate our cells we must take ampoules of seawater, including the original: QUINTON which has many other properties outside the scope of the subject. They exist in hyper and isotonia. Isotonia means identical to blood 9gr of salt per liter. Hypertonia: 30gr of salt per liter. And then eat raw vegetables and fruits that bring a lot of water and also help to moisturize the cells.

  2. It's weird before we get hydrated .. I never hydrate, at 61 no problem. It reminds me of the guy who throws powder through the window of the Paris-Nantes train. What is it asked of him? he says "it's powder against tigers" ... The questioner: "but there is no tiger between Paris and Nantes". The other: effective is not it ...

  3. Hydration is important during the effort, but also before and after, and I find that in general people are not sensitized enough.
    We can think wrong that hop a liter and the levels returned, but in fact there is a very great inertia and therefore an episode of dehydration can cause a breakdown a few days later if in addition the person does not have good hygiene in terms of regular hydration.

    As for drinking during class, I had a master who allowed to drink between two exercises. What averaged all 20 / 30min was to associate with a moment to blow.
    But 2 / 3 times a year it could happen a surprise course "dromedary operation", where have not drank the course, but it was precisely the kind of course that was accompanied by explanations on how to pay attention to its limits when one puts the body to the test and how to recover well from one kind of episode. And followed two days after a "soft" course.

    Thank you for this interesting article as usual.
