. . . what happens? From my admittedly limited knowledge of boxing -- perhaps applicable because of its nickname, the "sweet science" -- I know that impact to the stomach constricts the organs somewhat and makes it harder to breathe. But why? Is the body trying to lessen damage to the vitals by tightening? Does the impact simply force the air out upwards? Or are the lungs actually damaged somehow? This is just out of curiosity, so no rush. Sorry if it's a stupid question. ^^;; I'm particularly interested in why the effect is greater with impact to the solar plexus, as well.
