Re: Aikido IP/IS: Advanced Expositions in Centripetal Force

Mert, there's a lot going on in this video. It's reversing nikyo. Someone wants to apply nikyo on uke. Uke then is on the outside of the sphere and under centripetal force from nage. But in this case, uke changes something... He flips the polarity - changes the phase - of the power. From there, uke becomes the core - and creates centrifugal force and nage is moved through centripetal force.

The interesting part is - what is that switch - that reversal? What changes the phase, the polarity?

In looking at this video some comments........
  • In the uke-nage relationship illustrated here the uke has the mechanical advantage. Why would anyone want to apply nikyo up hill? against a straight arm?
  • Nage has elbow up and shoulder up….mechanical disadvantage…aside from energy flows….
  • For me as nage….if nikyo presents itself as part of the flow of things….I want mechanical advantage, I want to be above uke's hand, wrist, elbow and shoulder, not below them.
  • As uke being pinned I would rather rotate my hand/wrist/arm outward, clockwise if it is my right arm. Rotating clockwise in this case brings my pinned hand/wrist free of the torque being applied, brings my elbow into my body all the while extending and winding outward along a line from left to right while winding down on the opposite side left to right. Of course you have heard this before
