I think that the Dragonball and Dragonball Z series are somewhat based off the principles of what we know of as working with energy, only much further extreme. But as far as damaging Ki blasts are concerned, even Goku as a kid in the Dragonball series had to learn about "spiritual power" and how to harness and improve upon it. Also remember that Goku was a child from a different planet of a race of gifted fighters. Even as a toddler he was difficult to deal with even a grown man, A martial arts master named Grandpa Gohan. So I'd say genetics plays a big part in this. But then you have those humans like Krillin who are also gifted with strength and durable physical bodies. So it's a combination of factors.
I feel my energy in my body, I can push it pull it around inside of me at will. I can even feel my body vibrating at about 8 cycles per second (though its subtle, i can feel it even as I walk around and whatnot). I feel that vibration seperate from the breathing and heartbeat. So it's not like I'm having a panic/heart attack. I can even do what I feel is raising my energy up to the point of feeling a buzzing sensation on the outside of my skin. Not sure how far along I am, but I'm sure I have to be making some progress.
The problem is how to train your "spiritual power" to have more energy density and the ability to transfer it in an effecient manner into a contruct not unlike a "Ki blast" or a Kamehameha wave. The real trick, it to translate that spiritual power into your physical form to enhance your toughness, strength, and reaction time (among other possible implications).
So I HIGHLY suspect with proper training that DBZ-like "powers" can be possible. I know many in the PSI arena HATE Dragonball Z with a passion. Others like myself enjoy the series and other anime's that deal with energy based fighting and attacks. Remember that the DB and DBZ series is a manga/animation that's meant for adults and not for kids. The USA edits are often cut up to be allowed to play on the saturday morning cartoon line-ups. Read the DBZ translated manga, you'll see what I mean.
