Would someone please help me out here? I know what I think both anaerobic capacity and anaerobic power mean, but I've yet to see a good definition in print to confirm it.
Likewise, how would you define aerobic capacity as distinct from aerobic power.
anaerobic capacity vs. anaerobic power

Check out Jan Olbrecht's book.

I plan on doing so someday. In the meantime, anyone have an answer?

Power is a term used when there is an element of time. Capacity can be thought of as volume.
A commonly used test is the 30 second wingate test. You put a person on a bike and resistance is placed on the wheel. The person is told to go "all out" for 30 seconds.
At the end, you have a measurement of the amount of work done in joules. That is the capacity.
To get power, you take the joules and divide by time (30 second) to get watts (joule/sec).
Think of it as a tank of gas in a car. That gas has the capacity to take you for many miles, but you can also burn it off very quickly (power). 
Neither are technical terms with universally agreed upon definitions. Although "aerobic capacity" gets at something real I can't off the top of my head think of a precise definition. "Anaerobic power" is a bunk term as power is a proper physics concept and juxtaposing it with an energy system is simply a horrible thing to do.

Physics guys will cringe at the use of the word "power" here.
"Aerobic" and "Anaerobic" are also not great terms to use either..

Thanks, this is along the lines of what I was thinking.
