I don't think race has much to do with it. The genetic bell curve might though! I had a friend who was a amateur circuit wrestler and this is nothing.....
Dude. There are desperate wrestlers of all backgrounds doing the craziest shit you ever heard of to make it. It's just small town rural dipshits are stupid enough to film it. One of my best friends was a wrestler for years and it's a terrible life. That so many do it and only a few are able earn a living still makes this fact very sad.
Lame use of power tools. Both just let the other hit them with it one time to say they did. If you are going to take that much punishment, at least make something entertaining.
