Well, yes I do think we should attempt to define sparring, the OP used:
And while simunitions and the like clearly take away the importance of redirecting an opponents attack (duh
), they are absolutely useful for movement under pressure, maintaining good situational awareness, cover, and hitting targets under pressure. That sort of sounds familiar to me....
FoF training is also done with all of those standards in mind, you need to for the safety of the participants. As for "trading blows," I don't ever want to "trade blows," I want to hit him and he never hit me, I don't ever want to trade. Unfortunately it usually doesn't work out that way though.
For what I consider "sparring" it is exactly what the OP stated "freely trading, parrying, and blocking blows," but I usually try to mix things up a bit. All my beginners start with equal weapons (unarmed, knife vs. knife, stick vs. stick, machete vs. machete, etc) and then after their first year I mix things up. Usually starting with knife vs. club and unarmed vs. knife. I will also start people in compromising positions against the weapon (not 6 feet away). I absolutely consider this sparring, where most of the tools can come into play at hard contact. One of the things I repeatedly say in my class is "all training is artificial."
I consider sparring to be one of the cornerstones, the other three being basics, techniques, and drills.
