Greetings everyone! Still considering myself a beginner, I am greatly enjoying Aikido class. My Aikido instructor said that we are practicing the Nishio style of Aikido. I was just recently promoted from 6th Kyu to 5th Kyu. I have a question in regard to the following topic, please. Foot movement: Circular versus Linear? That is, having your feet tracing an arc along the floor, as compared to the foot tracing as being more linear along the floor. To give you some background in regard to the above, ... My instructor, whom I greatly respect, he always seems to be approachable, congenial, and informative. However, I would still prefer to not ask him the following question so as not to be misinterpreted in the slightest that I am disrespecting his teaching style, where I would then subsequently be faced with the awkward circumstance of an instructor having to defend himself against an inquiring student such as me. As you all are aware, any particular Aikido throw or technique requires Nage (Tori) to take more than one step. That is, as Nage, I am required to take several steps in order to position myself in order to do a particular throw or technique against Uke. Almost all of the steps, as taught by our instructor, of any particular technique involve the foot to trace an arc along the floor. However, I have observed in other aikido videos for other Aikido schools on YouTube that the students seem to be taught that the foot is not always tracing an arc, but rather, it seems most of the time, moving mostly in a straight line along the floor. For example, a good demonstration of this is the following video provided by, apparently, a company called Howcast, the video being titled “How to Do Tai Sabaki | Aikido Lessons” (3 minutes 27 seconds in length). [ame="https://www.youtube.com/watch?v=OQ7e-8yKfI4"]How to Do Tai Sabaki | Aikido Lessons - YouTube[/ame] Apparently, the footwork in the above video is referred to as ”Tai Sabaki“, which apparently consists of “Irimi” (spelling?), “Kaiten”, and “Tenkan”. Our class was never taught any of these words. Please allow me to mention that I have absolutely no affiliation whatsoever with the above company. I am just using them as an example to display what I am referring to as more “linear movement” with the feet (as in the video), as opposed to otherwise moving the feet in an arc fashion, that is, tracing a part of a circle (the way that I am being taught in my class.). Incidentally, I observe that “Howcast” has apparently many excellent Aikido videos on YouTube, with, what appear to me as, excellent Aikido instructors from, apparently, “New York Aikikai”. I can think of an advantage of moving linear (as opposed to circular) as it is displayed within the video, as it requires your foot to cover less distance, since a line is the shortest distance between two points. That is, the straight line is a shorter distance, than the arc or circle would be. However, by the same token, perhaps moving in an arc provides for greater momentum (?) as well as maybe better balance (?). Since, I guess, an arc is building up centrifugal force, it is, maybe, ultimately quicker as well as more powerful than would otherwise be if one was moving in a straight line fashion. (?) With the immediately above paragraph, I am now beginning to make statements within, what is actually for me, uncharted territory. Therefore, I will refrain from saying anything further. In regard to foot movement, Circular versus Linear, what do you think is better? If my above question is difficult to answer here on this wonderful forum, MartialArtsPlanet, through the use of words or language, I can understand, since it was somewhat difficult for me to articulate the background for this question. Any comments or feedback would be greatly appreciated. Thank you very much. The best to all, Greetings!
