An advantage with turning punches over?

Is there an advantage to turning the punches over (palm down) when jabbing over jabbing with the fist thrown vertically? I'm just curious if there's biomechanical advantage that I do not know of, or if there's good reason to use one over the other.

I prefer the vertical jab, when turning I have to remind myself of it constantly, doesn't feel natural to me.

Not sure if one has an advantage over the other though.

I think it was Scrap that pointed it out, that a properly thrown jab when turning over also produces more guard as it should rest your shoulder up against your jaw when complete. Thus naturally providing a guard of sorts for a counter right.

Also it protects the shoulder joint from strain, as it tightens the Tendons for the movement. Give you a clue, which way would your Hands be while pushing a car from behind, to protect the Elbow joint

Yeah, I remember reading that too, YB. I also recall this, in regards to throwing the left hook:

I'm curious if the palm facing the floor offers more protection, in regards to the body's mechanics such as protecting the rotator cuff, for instance.

That makes good sense. :) It's what I've wondered about. I didn't think that the tendons of the shoulder would be affected.

Anyway, one of the arguments for throwing a punch with the thumb pointed up is that the elbow isn't inclined to go out to the side when jabbing (no winging jabs). I found that this isn't a problem for turning the fist over when punching, so long as the elbow is not brought up too soon. Your example on jabbing next too a wall makes this point clear.

The Hook on impact should be in line with the knee and foot. Biomechanicly turning is the better technique it doesnt give the elbow to much air time

Plus the elbow is better to control plus you get better direction.

I realize that this is true. It does affect accuracy from what I've experienced. Thanks Scrap! Your feedback has been invaluable. That answers all my questions for now. ;D
