Ioulas,
The key is to hit the carotid artery, the sudden change in pressure and shock to the nerves will make the person drop like a rock,
you can do essentially the same thing when performing the blood choke,,, you cut the flow of blood to the brain, just for a second, and the person goes out like a light...
different variations are the leading edge of the hand, the knife edge, forearm, or palm.. also, hit through the intended target, not at it...
the last time I got hit like this was with a glancing blow, palm to the neck while me and another instructor were explaining glancing and stunning blows to a bunch of other Marines,,,
I sat down for a really long time afterwords...:whiteflag
This may help..
Natural Weapons Use
The primary functions of human body parts do not include using them as weapons, but this does not preclude using them as such provided proper alignment, structure, and energetics are adhered to cooperatively. A good example is the human fist. If used incorrectly, it isolates the intended weapon from the body’s root (earth connection) and can result in serious injury to the person throwing the punch. Aligned properly, all bones cooperate in transferring shock energy to and from the root resulting in maximum power with minimum damage to the person employing it. Of course, proper alignment and throwing of the punch won’t result in minimal self-inflicted damage if improper targets are engaged. Strategies, tactics, and training methodologies must all coincide so that proper targets for this particular weapon are selected and used instinctively. For example, hitting the head with a fist results in far more danger to the puncher than hitting the carotid, jawbone, or cheekbone/sinus cavity.
There are a number weapons that can be derived from proper orientation and use of human body parts, to include: palm strikes, finger thrusts, chops, elbow strikes, knee strikes, and kicks. All must be properly aligned (and properly released) to prevent injury to the user and ensure optimal results. The concept of Hung Fa Yi structural space (dealing with body alignment) complies fully with this requirement. In short, any motion or structure that defies natural body alignment of bones and muscles (alignment dictated by human genetic code), will by its very nature result in less than optimal efficiency and effectiveness. This leads to the second criterion
