squat, etc.). Of course, sophisticated testing apparatus exist, but not applicable or available (can you say "cost prohibitive" for most testing?).

Power is defined through physics as the time rate of doing work. We could then say that work could, in fact, be defined as the product of force exerted on the body and the distance that the body moves in the direction in which the force is exerted (whew!) Mathematically we can express
work as:

WORK = FORCE X DISTANCE

and power as:
POWER = WORK / TIME
Rewritten as:
POWER = FORCE X VELOCITY

Power then, is the result of the amount of force exerted on the body and the velocity of the body in the direction in which the force is exerted.

A broad yet, more meaningful definition would be that human muscles develop less force when they are shortened.

With respect to the hip and knee, research has borne out that maximal strength values are attained at the knee and hip,
