I know that when I was "growing up" in my studies of striking vital points, we were never allowed to smack certain points too many times...
In Yiliquan, we categorize vital points into Stunning and Painful, Temporarily Disabling, and Killing/Cripping points. There are also the Forbidden Points which are all acupuncture points.
The first three categories are mostly what I guess could/would/should be referred to as
atemi as opposed to
kyusho. There are many muscle, nerve and bone points (as well as combinations of all three) that comprise the bulk of the points in those groups.
Forbidden Points were always a no-no to strike with any degree of power or intent, not so much due to the danger of serious injury or death, but moreso because of the potential damage to the meridian system which would inevitably produce illness later on...
When I first started Iron Palm training, extensive
qigong exercise to invigorate the flow of
qi into the striking areas was part of the program. But, being young and stupid, I neglected that particular aspect of the training in favor of more time spent hitting the sand bags... Within a matter of days, I developed the worst case of explosive diarrhea ever recorded in medical history (well, maybe that is an exaggeration, but you should have been there!
:fart: ). When I asked my "older brother" about what was happening, he replied very simply "You aren't doing the
qigong, are you?" During Iron Palm training, with all the striking of resilient materials that is done, the meridians in the hands are "injured" and can cause illness. And boy was I ill...!
:fart: :rofl:
Curious to know the DKI take on this issue...
