I guess I am misunderstanding again. The ukemi that Hamatsu-san and Yamasaki-san are demonstrating in that video is the same ukemi that they do at the dojo. Are you saying that you would change the basics of your ukemi for a demonstration? I don't see why this would be necessary.
No. I'm saying the op was about the basics of ukemi not the form of ukemi. The main topic or point then went on to a basic called landing where you can't roll. So forget rolling or bouncing back up as that's not the topic.
The basic I was putting forward was relaxing into the ground. The very thing others were actually demanding I show them was not an example of someone doing this but an example of me doing this.
Thus in the video I finally provided under protest was an example of me being splattered. You see me flat out splatt. I'm saying that is a basic breakfall, very basic. If you apply it it looks like you should be hurt but you will not be.
It's not what generally springs to mind when the term breakfall is used, hence my pains to point out what I was talking about. A new look.
I did on one post say look at it like an aeroplane flight in four parts. 1) preparing to take off. 2) taking off. 3)the flight 4) the actual landing. Thus I said this thread was only about the landing bit not the form. Where body meets mat.
So it doesn't matter what part of body so much as what you do with that part of body and the impact.
(lets forget head here shall we)
Therefore if you relax the legs as the impact the mat and allow the energy to disperse it will and you will not get hurt legs. The same with going down flat on your back. These people generally find dangerous or painful or hurting but that's precisely my point. they needn't be.
Anyway, let's wrap this one up, enough already. Ha,ha.
