Hmm, in the descriptions of katame-no-kata always i read, that there have to be at least one defense action
of Uke, but i miss this in the examples of the first clip...
Yes, I agree with you. I did not see the defense action. Kodokan Judo: KATAME-NO-KATA from 43:00
- the uke first movement is 43:08, next 43:24 - he tries to catch tori . Tori executed the Ude hishigi ude gatame and after is small movement (turning body and feet moved just the little bit - 43:10, 43:26 - foot is propped on the tatami) of uke. I think that it is a hint attempt to escape.
Here is english part description from Dutch General Informations to Katame no kata ( http://www.jbn-zuidnederland.nl/judo/nieuws/181/katame%20no%20kata.pdf ) 2. Tori straightens up a bit, to stretche out Uke's arm, and brings Uke's trapped arm in an upward scooping motion as Tori twists slightly to the left to apply the arm lock.
3. Uke tries to escape by at least 1 method.
#1 Uke tries to pull his left arm downward by moving in toward Tori and twisting to the left.
4. Unable to escape, Uke signals defeat.
