Awesome post Nimvarus! Sadly I agree that many people dupe themselves into thinking that they are training in one thing, but really training in something completely different. 1. I agree that regular BBT training builds sensitivity, however in my experience it was mostly sensitivity to long energy and full body motion. there seems to be limited attention paid to short, fast energy like you would encounter in boxing, wing chun etc. What do you think? The opposite is also true which is why I loved moving from WC to BBT, I got solid exposure to both types of sensitivity. 2. I don't believe that is fails in the way you describe at all. Not all excercises can train all skills. I would never expect live training (sparring) to teach me how to avoid conflict, or walk away from it. That is trained in other ways. Sparring trains for when you are already in it. Why would you even expect sparring to teach the latter? Seems rhetorical and moot? Also note that I do not advocate sparring as your sole means of training. 3. True enough and in actuality a good heavy bag workout can teach that too...same with scenarios...I am not saying that sparring has this exclusively, just that it is a benefit. 4. Kinda...if you are saying that regular BBT training includes, spontaneous, un-rehearsed responses against an uncooperative uke then I agree. This was almost never the case in my training. It is the dynamic, uncooperative part the forces both gross & subtle adjustments...because you are adjusting to something that uke does unexpectedly...you just don't get this if you don't expose yourself to it. 5. - 6. Also, true enough. You would think that the technique would not be there if it had not been proven to work =) However, that having been said, everyone expresses the arts in their own way and so what may work for some may not work well for others. This is where dynamic application can teach you alot about what the traditional kata mean to you. 7. Very true! Look at MMA events for example...highly controlled, but they don't like to admit it. Again though, we need to be intelligent about our approach to sparring. What are we trying to gain from it. If you are looking for true "no rules" experience...well you need to become a criminal for that Also, the limits can actually be beneficial in ways. In escrima sparring (WEKAF style) you fight weapon to weapon. In doing so your targets are limited to areas that will be effective, but hopefully not land you in prison in a real situation. So sparring can also teach you the right kind of restraint. 8. Right, assumption being the key. Never assume. This is part of why I advocate sparring, as scenario training tends to do a lot of assuming. Important for skill building, not so good for applied experience. In my Sambo training, when we execute a throw it always works...which is good because I need to know how to do it. When we sparr, it does not always work which is good because I need to learn to adjust it or compensate. 9. Only true to an extent. First off we always advocate sparring with people you don't know...better experience that way. Second, there are certain things that you learn VERY well through sparring. Example, being hit in the groin will not always double someone over. A boshiken to the ribs may not actually hurt at all etc. etc. You learn to weed out, or modify a lot of stuff because it simply does not work against 200lbs. of raging flesh and bone. This trancends that fact that it is learned through sparing because it is more basic than that. So no, what you learn in sparring is not limited to only sparing applicable techniques. Again, that having been said, sparring can teach you bad habits and stuff that would only work in sparring...like sacrificing your head in order to give a shot to the body...bad form! =) You just have to be intelligent about your training.
