"it's defined as the work required to raise 550 pounds a distance of one foot in one second"
That's the definition of hp on this site: http://outside.away.com/outside/envi...01wildfile.adp
If you take time to read the article (third question down I think) it mentions why horsepower can't be measured by simply distance, body weight, and time... it also says that the world's strongest man could generate 5.84 hp.

I got somewhere around 7 horsepower as a 7th grader. I'm gonna say average male is 12-14 horsepower. Remember, we're not geared. Also, my science teacher may have been full of balogna.

1 hp = the ability to vertically displace 550lbs, 1ft in 1sec

HP is the RATE of doing work, Torque is the instantaneous force over a distance, usually one foot.
A horse does not raise 33,000#s all at once. It is the amount of total weight moved over a set time frame. Probably detailed in the Wikipedia article.
Likewise a tiny riceburner car has lets say 100 foot pounds of force. That means in non scientific terms that the engine can sustain 100 pounds of weight at a distance of 1 foot without stalling. Doesn't mean it takes a minute to do it, the force is constant. This is also the force a typical man could easily exert, we do it all the time when we torque some lug nuts. 100 foot pounds is pretty puny.
However that same car can move its weight say 2,000# up a hill much faster than than a man exerting 100 foot pounds could.
Probably lousy examples, but HP and Torque are not the same but they are related over time.
Just my unscientific opinion,
