No we don't have it in GB (I think).
Why do they use chi?

Yes they use the jutsu style mentioned in the last paragraphs of the article.They concentrate much on the chakra on the series and it's interesting to follow and their style of martial arts.well they are fictional but it's worthwhile to see.

i'm an amateur when it comes to chakras and manipulating the energy in the body but i do understand martial arts and i've noticed that if i push energy out from my body in every direction as far as i can that not only do i stay aware in a bout but i also anticipate my opponent(s) more easily and more fully, not meaning to teach any of you but i haven't heard a suggestion like that

Kudos on this post!


Ive practiced Capoeira (brazilian Martial art & no its not like dancing) lol   and in it we use the same breathing technique that is used in yoga, because it helps us to be able to hold down different takedowns and defense  techniques.  The most fundamental movement in capoeira is called the ginga, from the ginga all movements are formed. Your whole focus and energy goes to the center of your stomach. Now it makes sense to me as to why we have to do that.  In capoeira we are taught how to block people from entering your focus zone. because when you are in the roda(circle) the only person that matters is your opponent.  I guess that is what you guys call it 'blocking' psychic attacks? I'm not sure if I'm right or not.  I have to go back to training soon, its been too long. ^_^
