The sweeps are a direct application of the principles, skills and movement trained in the katas. To view kata as a dictionary of all the techniques in an art is a very limited view of kata. And it significantly limits your view of the art.Where do sweeps in Shotokan and Goju Ryu sparring come from if it's not directly from a Kata?
Done. There's no use of the arms.
For anyone else interested in the topic, do your research. It's true you have to follow a certain training methodology and progression path with partner drills before you see things. It's not for everyone - those needing a literal translation, I suggest just training without kata and forms and going straight to a fighting gym.
You haven't even watched the clip in the OP. Do that first. Do you think that flows naturally from the curricilum?
Nah. Waste of my time. If you don't see it, that is fine.
I'm really talking more to other people. They should be aware a sweep is a common application for nami ashi geri as cataloged in Naihanchi/Tekki and if they want to train it in that way they need to see out the proper teacher and methodology to make it work.
Yeah I don't see any pulls in the katas, which usually accompanies the foot.
So that's why I'm interested how it became a scoring technique in Shotokan.
