Re: Poll: How important is physical body size for effective aikido techniques?
I don't think I understand the question:
A person of larger physical body size can utilize more force and mass for his techniques then a light and small person. But, a technique could still be effective, at least against most people, even if it is only done by a smaller person, that is assuming we are talking of people with similar high level skill.
Size does matter, technique Quality matters more, the outcome requires both and a few other things.
