Fast contraction runs counter to old-school weight training advice. Interesting.

Not necessarily based on my knowledge of basic exercise science (admittedly limited). There's a difference between Power and Strength, as the first few paragraphs of the article explain.

There is a major component of velocity involved in Power and athletes usually train for power to enhance their performance. I believe this is also related to "fast-twitch" muscle fibers.

Strength on the other hand is not concerned about velocity at all and only considers the muscle's ability to overcome resistance. If you're just trying to get ripped, you don't necessarily need to train for power.

Tldr; Power = Strength with velocity
