The Short Answer

You know when you hit your leg on something (like you bring your thigh up into a bar underneath the table) and you pause whilst cursing the pain because your leg kind of seems to go numb for a second? That's your body very temporarily immobilising the area to make sure nothing is SERIOUSLY wrong with the part of your body that got hit. The same thing happens with your diaphragm (the chest muscle that pulls down to make your lungs expand) when you get hit in the torso. A second or two of no diaphragm contraction means a second or two of no inhalation.
