I wrote in the previous article that Aiko San could correct my technique without looking at me, just by listening to the breath.
Why is that important? Because while at the beginning levels we focus on external form and mechanics of technique, at the higher levels the breath controls the techniques— all aspects of it— and the mechanics and form should be forgotten, or not consciously attained.
For example, breath initiates the technique, acting like the trigger that controls the timing of the technique. If we cannot apply the concept of “breath triggers technique,” we cannot talk about breath reaction (rather than conscious, analyzed decision reaction), since action and reaction must be one, without space, and that is only possible if the breath makes the reaction and initiates the technique. Also, the concept of breath tuning to the opponent’s rhythm while creating potential energy in our footwork is not possible to apply if breath does not match our footwork and technique.
Or, as Sensei Nishiyama used to say, “kiai destroy opponent,” since the breath controls muscle activation at kime. It controls pressure to the floor and total muscle contraction in the shortest time to the line of technique in case of “todome,” or continuous contraction in case of push-and-pull techniques. In other words, breath creates kime and also controls the type of kime and energy appropriate to purpose.
When we say “kiai destroy opponent,” it includes intention. If the intention is “to destroy opponent with kiai,” the muscles will be recruited more sharply, more fully, and in the right direction according to purpose.
Now, this is not an easy subject. Proper breath is not simply blowing the air out. I would not have been able to understand the breath without countless demonstrations and feedback by Sensei Nishiyama and Aiko San. With this being said, anyone can attain those levels, whether athletic or not.
This is why kids karate classes are so valuable—they teach young learners not just physical techniques, but how to use breath, focus, and intention in movement. By attending kids karate classes, children gradually learn coordination, timing, and control, all while gaining confidence in their abilities.
Additionally, incorporating principles of breath and technique into self defense classes for kids ensures that students understand how energy, timing, and awareness play a role in protecting themselves effectively.
For those beginning their journey, even in kids karate classes, it’s essential to study deeply and diligently, and to be patient. Progress comes with consistent practice, proper guidance, and a focus on both body and mind.
