I have my doubts about resistance. That's mainly a competition thing, like in judo: not wanting to be thrown. The attacker attitude is not 'not being beaten', but to beat up the other guy. So, attackers tend to be very aggressively offensive, not defensive at all.
An aikido that aims for "realism" should base its solutions on that.
Thinking of this thread, and the atemi one, I made a short film yesterday after class, trying some atemi applications and a couple of aikido techniques in a way that I regard as "realistic".
No doubt, that will be questioned
Here is the video:
Thanks for the video Stefan .It reinforces my point. If one wants to practice using Aikido with "full resistance" Atemi must be considered otherwise you have bad Judo. LOL
On a side note it's curious to read that people have lost almost all their encounters because of Kata.
