My daughter is a Karate Jr. brown belt and we had discussion the other day concerning certain "mind over matter" martial arts like Qi Gong and other Shaolin special studies like the Iron Shirt technique. I went looking video demonstrations, when I stumbled across these clips.
I don't wanna burst any bubbles (pardon the pun) as the "squaring" move itself is generally thought of as the ultimate defense against a male opponent,
however, this is proof that it and other blows considered potentially lethal may not have the intended effect on one with the proper training.
Yep, I'm talking about the official World's Record kick to the groin.
[link][link]I'm pretty sure my reaction is one shared by 99% of the rest of men out there (and quite a few women)....

OOOOOF!(knees together TIGHT)....

tiny gasp.
I can say rather uncomfortably I can relate to this. I've taken a similar blow in the past. Short story, I saw an obviously drunk girl getting beat up by some guy. I stepped in & tossed him off her. She thanked me by hoofing me FULL FORCE for hurting her boyfriend!
No, I don't for a moment think the kick I got was anywhere near as hard...
though the reduction in forces didn't help me any.
She was behind me at the time - I never saw it coming.
For me there was a bright flash, then black.
My reaction was closer to the guy with the tennis ball...
only add 20 minutes of unconsciousness, directly followed by an hour of puking & another 2 of breathing difficulties... followed by weeks of bruising. (LOL! BTW, Did I ever mention I HATE pointy toed shoes.)
Just the thought of someone like Justice doing that ..

... makes me want to double over in sympathy.
If I did managed to survive taking that kind of a blow, it would be a case "mistaken resurrection", because I'm pretty sure it would be 3 days after the ink on my death certificate had dried IF I ever managed to take another breath.
The whack to the throat was very impressive too and would have incapacitated a less trained man.
That kick though...
1,100lbs! WOW!!!
It clearly lifted him off the ground!!
Yet his pulse never changed.
Mr. Kirby Roy, YOU have my utmost respect & I salute you.
Can't say I envy your training regiment though...a minimum of 5 years of taking the practice punts.
