There are two type of breathing use when performing a kata. The first is called “ibuki” or quick energy breath. Ibuki breathing is done at the execution of blocks, kicks, and punches. The second is “nogare”, or slow breathing. Nogare breathing is usually done when moving from one position to the next or when there is a pause in the kata. Through the practice of proper breathing the student is able to keep mental composer throughout practice in the dojo and in his everyday life. Correct breathing will enhance a students mental and physical endurance as well as his concentration, focus and develop the warrior spirit necessary to be a good martial artist. Effective and the body.

Tan-den Contraction

 

• This exercise involves the contraction of the lower back and abdominal muscles and the buttocks. Exhale forcefully and begin at the bottom of the stomach. This method of exhalation helps strengthen the abdominal and back muscles. Stand with the back against a wall and take a breath through the nose, not inhaling too deeply. Begin to exhale and press the tongue against the roof of the mouth and make an “R” sound. Squeeze the buttocks with a tight muscle contraction, and pull the tailbone upward toward the abdomen. Keep the small of the back against the wall. On the exhale, punch out while forcing air out of the body through the mouth.

 

IBUKI BREATHING

 

Correct breathing technique is vital to the correct performance of Karate. Breathing helps the student of Karate relax and oxygenate the body. More oxygen in the body increases energy and stamina. The body is also united with the mind and the spirit as the student practices controlled breathing. Typically, ibuki breathing is the inhalation of air through the nose prior to execution of a move and then strong exhalation through the mouth upon execution.

A. Bring your feet together and arm’s to the side, you should be totally relaxed and not moving, looking straight ahead.

 

B. Then moving into a difference stance called Sanchin Dachi or half Heiko Dachi, draw your arms in a large circle, moving very slowly all the time. While you roll your arms in a large circle, breath in air slowly and quietly until you have taken in as much as you can.

 

C. The breathing in motion should stop when your arms have crossed above the head.

 

 

D. As the arms come down. The expulsion of the air should begin. Normal breathing is done by inflating the lungs and then deflating the difference with Ibuki is that the breathing is done with the stomach. The Japanese name for this part of the stomach is called tanden if translated it means the soul. The tanden being the center of the soul. From this point the air is forced out. The Larynx, the upper structure at the upper end of the trachea in the throat should be closed as small as possible. The air should be forced out through this small orifice making a very loud noise. Continue this until all the air is out. Your muscles should be totally locked and tight.

E. With all the air out, the tension should be kepted for a period of two seconds.

 

 

F. The last air in the mouth should then be force out making a short “Ka”sound. This is then the strongest posture. Ibuki is training for gathering power in a very short time.
