I'm looking for technical information about the damage that each submission inflicts. I figure we could either have some knowledgeable people post, or provide a few links to useful websites with this sort of information. I realize an armbar is going to fuck up your elbow joint, but what are the specifics. How does a move work, and why? What damage will it inflict? Does it tear ligaments, break bone, etc. How do chokes cut off your air supply and strangle you, the 2 arteries running up the side of your neck? I'd like to be able to explain when asked or telling someone of a move what exactly it does and why, and not think to myself shit is that right?
