In Karate, the term has two applications; an Eastern and a Western one.
The Eastern is extreme decision or focusing energy.
The Western is short isometric neuromuscular contraction and is based on the science of biomechanics.
This means you must quickly tense your muscles (snap) at the moment of impact, but not so much that your muscles are shaking.
Your ability to coordinate your muscles, and quickly relax before and after a technique, directly effects your kime.
That’s it. No magic tricks or strange sounds with your mouth.
