Proper form is what prevents harm to limbs. Slapping and pseudo-conditioning HARMS limbs. Period.
I'm confused about your remarks. You're saying "simple studies may
reveal..." Are there actual studies you're refering to which do prove what you're saying or are you guessing at the truth of the matter? My understanding, highly limited though it may be, is that there is a natural benefit to impact conditioning with regard to strengthening things like bone and skin. I think I share your esteem for the power of sensitivity which is why I don't do a lot of heavy impact training, but I wouldn't call it pseudo conditioning to develop callouses or add bone density through impact-oriented training. Conditioning of the body includes more than developing the neurological system (coordinating system) so we can respond accurately and smoothly. For me, at least, it also includes a modicum of "toughening up." Impact is a way to improve this. It's not any different than lifting weights to improve power. When you stimulate the muscle, it responds (I've heard this refered to as a shock to the muscle). If you stimulate it too much, you injure it. If you don't stimulate it enough, it atrophes. Conditioning other elements of the body, like bone, is similar.....I think, anyway. Hope you can shed some light on it for me.
