The "energy dump" theory has been thoroughly disproven. If you take a look at the amount of force sustained from punches and kicks, there is a substantial increase in energy delivered to the target. Various professional MMA fighters, boxers, kick boxers, etc have been tested, so there is scientific data out there. With the logic surrounding the whole energy dump theory, the increased level of force delivered by a punch or kick from a professional athlete should be enough to instantly kill you and throw you across the room. I forget who it was but, there was one of those guys that was measured at I believe 1,000lb/ft of force with their punch! That's twice that of a .45acp and delivered over a broader surface area.
In addition to that, there have been studies done showing that "temporary cavity" in many cases really has no effect in determining what stops the target. It's all penetration and damage to vital organs, it's that simple.
