I don't quite think you're 100% on what you are saying, D. Kurz puts emphasis on dynamic stretching, which
directly crosses over into
any striking art. Give me any student, be it TKD, MT or Kyokushin, and with one session of dynamic stretching, they'll be kicking a lot higher than with any type of passive, static, or isometric stretching.
As a side note, Kurz holds BB in Judo, Kyokushin Karate, and TKD. I've seen him throw a roundhouse at a focus mitt held almost 7 feet high. Believe me, what he preaches he practices, and the results show.
As far as yoga is concerned, even Ashtanga yoga doesn't develop they type of practical flexibility that dynamic stretching would. And while Hatha yoga may develop passive static flexibility, it doesn't cross over into dynamic flexibility as much as people are lead to believe. Active static flexibility (static holds) are good for static strength, but not developing full ROM flexibility. And yes, I've done both Ashtanga and Hatha, and both have merit and compliment any MA.
You are 100% correct on practicing movement through a full ROM, though---that's a key a lot of people miss, but I don't think yoga addresses this fully, IMO.
For simplicity's sake, here a very basic breakdown the types of streching, and what and when:
Dynamic: mornings, before a workout
Passive Static: after a workout,
never before (this one too many people still do.)
Active static: Why, I don't know. Think of a floor gymnast holding a pose, or a ballet dancer. Not really applicable to a martial artist, IMO
Isometric: Advanced stretching if one wants to obtain a full split. Similar, but often confused with PNF stretching.
I had a rude awakening at age 29 after tearing my ham when I was trying to get back into martial arts. In the four years time since then, I've educated myself a fair amount on flexibility training, and I can easily say I'm a helluva lot more flexible at 33 then I was at 14. As you can also see, I'm a bit passionate about teaching and explaining proper flexibility training also.
