This has been bugging me for a long time, basically since I found I couldn't use any of the uke techniques as advertised. Partly from my Shotokan days, but the shito-ryu clubs I trained at also made use of exactly the same kihon techniques, obviously in a more constrained style. Someone, somewhere has at some point come up with a list of techniques pulled from the katas and turned them into "basics". Why these techniques? and did they have any experience of how you use them? I have a feeling they didn't.
In kata they are just movements. Kamae - postures. There's no direct intent associated with them. It's like the difference between the word thrust, and the word punch. Thrust simply describes a motion. Punch gives specific intent. Tsuki obviously means thrust, not punch. We have projected our own intent on to the movements.
The punches and kicks as kihon... ok fine. Punching and kicking are basic and fairly useful. The various ukes as trained in kihon appear to have little or no correlation to their use in kata. i.e. in kata the movement is unrelated to punching of any kind.
Do you practice kihon? A set of fundamental techniques? If so what and why?
