A lot of what I've been taught, especially the past couple of years, is what is called a block or a parry, really isn't. I've been, to great effect even in a couple of "street" situations, training where the "prep" to the technique deflects the incoming attack and the block or parry is is actually the strike. Makes those preps really useful.

Does this mean you train to approach an encounter with your own arms hanging at your sides? I would hope not, they should be up as well. Wow, already most of the way to a parry/block, so the argument of being quicker is gone....
My thoughts: They are not the "be all- end all" but they are very useful. No I'm not lightening quick, yes they work.
As for showing you where they work outside of the dojo, I personally don't cart around a video camera and somebody to run it 24/7, and if I did, I still wouldn't post those types of clips. You still wouldn't believe it anyway.
Can I prove to you they work? Nope.
Do I care? Nope.
As long as you are comfortable with the training and your instructor, that is what matters, not what others you don't know think. But, the other side of the coin is the fact you are not going to convince those of us who kknow they are useful and good otherwise either.
Senin, I want to underscore what Jeff and Scott are saying here and maybe amplify their points a bit, because from what you write I think you have an idea of what a block/parry is which doesn't match up very well with the experience of the other posters on this thread. I can't tell from you profile how much time you've spent in the MAs, what kind of Budo you pursue or what your training experience has been like. But it's pretty clear to anyone who's thought hard about the relationship between MA movements on the one hand (motions of various parts of the body in descriptions of combat techniques) and the actual moves those motions correspond to on the other (actual applications and use of the movements in question) that the names of movements and their actual combat use are quite different. A `block' is virtually never a block, with you just standing there, trying to react fast enough to what some guy is throwing at your head. It's almost always a deflection of a strike that you've already moved out of the way of. In the scenario I described to you very early in this thread, the key to not getting hit is turning 90º to the attackers inside; that is going to be a lot quicker, as a movement, than standing square on to him and just using your arms in an effort to keep the blow from landing. But your goal isn't not getting hit; it's incapacitating your assailant tot he point where he withdraws from the fight (volunarily or not). So you must combine your movement inside with a way of grabbing the initiative, right? And since he's already commited to the punch, once you've made the quick (and largely instinctive) movement to move to his inside by turning your right side to him, you have, relatively speaking, a lot of time to counter his attack so decisively that you can finish him.
Jeff's point about how to break a supposedly defensive move down into parts that show its largely attacking potential comes in here. What he says about the role of the `prep' part—that if you understand it right, it's actually the deflecting component, and the so-called blocking motion is actually the nearly immediate attacking component that the prep sets up—is exactly on target. Karateka like Bill Burgar and Iain Abernethy, and TKDists like Simon O'Neil, have been stressing this for years: in most `blocks' (the name of the movement), the so-called `chambering' part (the name of the submovement) is actually the deflection—with a double knifehand block, for example, once you've turned to the assailant's inside, left hand/arm movement back is the deflection, but the simultaneous right hand/arm back strikes vital points on the assailan't upper arm, triggering a physically instinctive turning of his head and shoulders away from you. Your next movement—the actual `block'—involves your right hand striking his face on the side, and your left hand striking his neck or throat immediately after that. Muchimi tech followups should guide your conversion of the strike into a hair or ear grap, say, with a low hard sidekick to the sideof his knee, damaging the joint, possibly severely, or an hard elbow strike with your right elbow back to his immobilized face, and so on. These are just basic realistic apps of standard karate/TKD `block' interpretations, illustrated in e.g. Burgar's book in detail.
As Scott points out, just having your hands up and your arms in a basic `fence'-type position is most of the `parry' right there. Turning away from a punch is something that you can do a lot quicker than your assailant can throw the punch—even at CQs, look at the difference in the distances involved! If you train for that kind of movement (or the mirror image in response to a grap to one side, where you can quickly and effectively turn to the assailant's outside)—as I would expect you to be doing; this is just Realistic MA Techs 101, no?—your simultaneous deflection/strike sequence will take the steam out of even a very worked-up attacker. You have to train this kind of response, sure, but again, a lot of it is instinctive response. And as Scott also says, lightning-quick speed isn't required. These arts were designed for civilian use against common civilian attacks. Most people not only aren't as quick as Bruce Lee, they never were at any time in history. So how did these arts survive over centuries if they actually demanded that kind of speed?
I think what people are showing in their responses to you is a kind of puzzlement that this kind of very basic technical element in your MA training seems to be... missing. In my TKD school, this is the sort of stuff that green belts learn. Is it that your instructors haven't shown you this way of utilizing technical resources from the MA toolkit?
