Doc, can you elaborate on how you feel a push is "stronger" than a punch? Are you comparing a two handed push to a single punch? I think I see what you may mean in that case, but if you are talking pushing versus punching, my experience has been that punching is stronger and more damaging.
Neurological feedback can take pleace in fractions of a second. In terms of wrecking power, of course a punch will have more potential...you're throwing a stone, so the rules of ballistics are more apt to apply (mass x acceleration, area of impact being concentrated, blahdy blahdy blah).
But consider a bench press, and the mount of muscle recruitment, as oposed to a open kinematic chain punch.
Traditionally, a closed kinematic chain is when a limb makes contact with something solid, such as the ground, or something rooted to the ground (wall, standing person?). Think squats. Open kinematic chains don't touch something solid. Think thigh extensions. Closed chains give the body more time to proprioceptively clue in to a focus point. Open chain ballistic movements fire harder, but recruit less of the mass of the involved muscles, and lack as much synergistic coordination/cooperation.
Pop a guy in the mouth: Ballistic movement, travelling through most of it's arc without feedback about directional resistance. It could fly wide, low, high, shallow, and you wouldn't proprioceptively know until the moment of impact, and the final miss/hit status. Pushes take more time, and provide your body an oportunity to decide how to get all parties on board in the same direction (all the muscles working together in a group, with instantaneous, ongoing feedback through the spinal cord about who gets on board, where, and with how much emphasis).
Student of mine is in the 400 lbs bench club. Can push like a maniac; I use him for demos, specifically for this purpose. His stance ends up being like a linebacker when launches me bass ackwards. Punching, however, he's much weaker. With time, training, and technique, I'm sure Doc Stone will be a wrecking crew of a puncher. But for now...not as many notes in the symphony of neurologic noise in the punch, as in the push.
Punches hurt more because ofthe focused point of impact. But, unfortunately, there is less muscle involvement in an unclosed ballistic throw, than in a constant-pressure contact.
I could go more into detail, but that would require writing a book. Literally. Just finished reading a text on ballistic throwing biomechanics, and their applications to sports activities such as tennis, golf, and pitching. Exhaustive, and not worth re-typing here. If you want to read it, I'll post the reference. Otherwise, that's all for now. And the jist of it.
