Not so much, since you're talking about untrained fighters. I am involved in a physical confrontation on a regular basis. At least once every couple weeks. Untrained fighters mostly forget that they have two arms and two legs. At least briefly. Because untrained... And before they remember, I can put them on the floor, or into a wall, or whatever.
It's even better when they have a weapon. People with a weapon in one hand, even if it's just a stick, seem to totally forget the rest of their body. Control the weapon arm, and their whole attack falls apart.
It's a different story if they're trained, of course.
