Relaxed Movement in Aikido

When watching old aikido videos, I get the sense that Shioda Sensei seemed to move at a different speed than everyone else. He moved at normal speed and seemed to have had some frames removed from the film.

Koichi Tohei Sensei, on the other hand strikes me quite differently. It's not that he seems to move more quickly than those around him; it's that he seems so relaxed. It's like he's just moving around, doing what he's doing, almost unaware that people are hanging on to him ... for a short time.

Here he is below. Enjoy.
