Power = Force x Velocity (article)

marathon runner, in which case you can just slowly jog away from this email
right now because this doesn't apply to you.
But if you're involved in any other sport that is worth watching, like MMA,
football, basketball, hockey, soccer, etc, then explosive power is what makes
those exciting plays happen.
You know, when someone lands a big knockout punch or takedown, a
running
back breaks through the middle of the line, or Blake Griffin
soars through the
air and throws down a big dunk.
Well there's no better way than adding in the Olympic lifts.
In fact, science has proven it.
In a study published in the Journal of Strength and Conditioning
Research in 1993
called "A Review of Power Output Studies of Olympic and
Powerlifting: Methodology,
Performance Prediction, and Evaluation
Tests", author John Garhammer performed a
biomechanical analysis of the
Snatch, Clean and Jerk, Deadlift, Squat and Bench Press
to determine how
much power was being generated during each exercise.
Before we get into the results of the study, you must understand how power is
calculated.
Power is calculated by the following equation (it's math lesson time - yay!):
Power = Force x Velocity
While velocity is simply how fast you move the weight, Force = Mass x
Acceleration,
how much weight you move multiplied by how much you
accelerate the weight.
That's why with respect to power output, lifting heavier doesn't
always mean lifting
more powerfully, because whenever you add weight,
you will be slowing down the lift.
Now let's take a look at the results of Garhammer's study...
Garhammer analyzed video of elite lifters and calculated their power outputs through
some really intense mathematical analysis.

Basically, what Garhammer found was that during the Clean
exercise, a 100 kg
lifter generated 4191 watts of power, while during
the Deadlift, 1274 watts of
power were generated!
The reason why over 3x more power is generated by the Clean is
because the lift is
performed so much faster and over a much bigger
range of motion - it takes about 1
second to get the barbell from the
floor to the front rack position during a heavy Clean,
while it can take
anywhere from 4-6 seconds to get the barbell from the floor to the
thighs in a Deadlift.
So if you're looking to improve your explosive power for your sport,
jump higher,
or just learn these highly technical exercises because
you'll get a kick out of seeing
the looks on people's faces as you do
