The Kinetic Chain

KINETIC CHAIN

TIMING OF TECHNIQUE

Sensei Nishiyama used to say: “ what is the point of having 8 cylinders if we use only 2”.

He also used to joke: “we don’t need muscles like Popai, we need to learn how to use what we have”.

In a karate hand technique, but also in overhead throwing motion and other functional movements, force is summated through the kinetic chain via force production at the various joints, from the lower body to the hand.

Any change in timing or force generation may result in poor performance and or eventual injury at another level within the chain.

The kinetic chain is only as strong as it weakest link.

Functional movement is never isolated, because it is produced by several muscles acting as prime movers, synergists or stabilizers that coordinate together.

Functional strength does not require maximal activation, rather optimal activation in precise timing is more important.
