Nikyo
I saw this video today and I had some questions about this. I get what he is saying about the release, but it seems to me there are some problems with the application of the technique. I seems to be way out of center and they aren't moving. Was interested in what other people here would think about this.
What he's demonstrating has always been one of the fundamental problems with join locking techniques in that they rely on pain to cause uke to react in some way rather than the movement of center, and pain isn't always reliable. For one thing, you may be a tiny person and uke may be a big, giant muscle-head. But more importably, uke can always go with the direction of the "cranking" and reverse it in most situations, much like this guy does (Nick demonstrated this with the sankyo lock during shochugeiko the other week).
Another problem is tori usually has to stop to inflict the pain of the joint lock and if uke keeps moving, tori has a problem. It may not seem at times in this that tori is moving, but while he's not moving his center over a distance (taking steps), he's usually at least TURNING it with the release action, which is still a moving center.
And while we usually keep our arms in our centers, it does move around on occasion into other positions that are still pushing positions. The main action they do looks a lot like mae otoshi to me, where our arm is more out to the side (like gedan ate). Once or twice toward the end, though, uke does a release like action where the arm is more in center.
My two cents, anyway. This is a good find, though.
Of course, one CAN use various wrist and elbow techniques like tenkai kote hineri, kote mawashi, kote gaeshi or others as control mechanisms (like Cindy did with kote gaeshi to a dude who goosed her while she was at work). Just put uke in a situation and wait for him to get out of it and use that energy against him. It's when you start cranking, trying to inflict pain, that uses energy and a directional flow of energy that uke can use against you...
static pain complaince techniques are woefully unreliable -- joint locks that affect asymetrical loading of the posture in a dynamic moment are sweet -- most folks who do kansetsu waza fall prey to the static cranking model in one form or another -- if they play enough toshu randori they usually get cured
If those guys putting nikkyo on took a step backwards they would tie him up. No kuzushi no throw.
I don't attempt to lock till I see a bend in the spine.
Thank you. Makes more sense to me about what they are demonstrating and why they are able to get out of it.
