These guys are doing some interesting wrestling. I have trouble saying they are practicing aiki though. Using the randori method of training is a tightrope walk between reality training and non productive training.
You see, they are moving to fast for their skill level. They are trying to fabricate technique when there is non to take.
I would like to digress for a moment and talk about calligraphy.
When I moved to Japan I started the practice of calligraphy. I was not interested in the stiff forms, and learning the proper brush strokes. I wanted to do the large swirling pieces of art. I wanted randori, without studying kata or understanding the principles of the art form. My calligraphy looked like a train wreck.
Similary just jumping into randori, you will get a similar result. You must learn the principles, so technique will emerge. A strong philosophy of what you are doing must be in place.
What I am seeing in this video is crashing energy. I am seeing people trying to throw, then people trying to feel. I see people afraid to lose, so they are willing to violate the rules and principles of the art they are trying to learn.
Here is a video of what we consider randori at KyuRyu AikiBudo. Me and Mike could easily attack each other to the point where we would be struggling - rolling around on the ground biting each others ears off. We have to slow down, and attempt to obey the rules of our ethics and art form. We are allowed to counter, but we are not afraid to lose. We walk the line of reality training and training at a speed where we can actually learn.
I suppose either method is practice. But like Kano Sensei taught, I am searching for maximum efficiency with minimum effort.
