To understand the effects of Olympic lifting on pitchers, you must
first understand how velocity is measured. I will use Newton's second
law of motion, along with the Catapult Theory, to explain pitching
velocity.
Newton's Second Law:
States that
the acceleration (velocity) of an object in motion is dependent upon two
variables - the net force acting upon the object and the mass of the
object. As the force of propulsion acting upon the object increases, the
acceleration of the object increases. As the mass of the object
increases, the acceleration of the object decreases.
Newton's 2nd Law of Motion
a = f/m (f = force, m = mass, a = acceleration)
Let's
put this into baseball terms. Newton's second law of motion would state
that to throw a baseball 90 mph would require 6.5 pounds of pressure
applied to a baseball, with a mass of 5 ounces, for two tenths of one
second (.20).
6.5 pp applied to a 5 ounce baseball for .20 seconds = 90 mph fastball
Therefore
to increase an 80 mph fastball to 90 mph you must either increase the
force applied or the application time. The application time is how long
you hold on to the ball once the force is applied. Subtracting 25% of
application time forces a pitcher to increase the applied force by 33%.
Increasing the application time by 10%, increased to .22 seconds, would
add 10 mph to an 80 mph fastball.
80 mph fastball + 10% more application time = 90 mph fastball
Catapult Theory:
The
Catapult is made up of three components: the pivot, the coil and the
arm. Let's add a ball to the end of the arm to represent a baseball. To
measure the velocity of the baseball, after the arm is released and the
ball is in motion, we use Newton's second law as described above. The
importance of the Catapult is its relation to a pitcher at his full
range of motion before launch of ball (See picture of Nolan Ryan below).
If the Catapult pivot is not stable and is moving forward during
release of the arm, then this will decrease the force applied to the
ball at launch. In return, poor velocity. Now, if we stabilize the
pivot, meaning no movement, and continue to apply the same force to the
ball. When the arm is released and the ball is launched, it will reach
its potential velocity. To keep force applied to the ball consistent the
coil must maintain pressure on the arm during the entire delivery
process.
How does Olympic lifting come into this equation?
First reason, it is the only type of lifting in the weight room that trains triple extension.
What is triple extension?
This isn't something new to the sports world. Olympic lifters have been
using the term "Triple extension" for a long time. Triple extension
occurs when the ankle joint extends, the knee joint extends along with
the extension of the hip flexor. Visualize a long jumper in mid air like
above (Notice left leg in triple extension). Also notice, in the
picture to the right of Nolan Ryan, his right leg has triple extension.
You can see his ankle, knee, and hip flexors in full extension. There is
no weight lifting that trains the body pushing off of the ground as a
single unit better than the Olympic Lifts. Triple extension plays in
every sport that involves pushing off of ground.
Second reason,
notice the lifter doing a split jerk at the top of the article. This is a
very similar movement to pitching. More similar than any other weight
training exercise. Studies have shown that athletes get better when
training within their sport. This is called sport specific training.
This
lifter is using triple extension to drive the weight up. Just like the
pitcher driving the ball to the plate. The only difference here is the
consequence of error. If the lifter losses momentum in the hips, he will
drop the weight. If the pitcher losses momentum in the hips, he will
throw a home run to some lucky batter.
Now, how does triple extension increase velocity?
In
all ways described in the Catapult theory above and Newton's Second
law, it adds both application time and force applied to ball.
First
let's explain how it increases application time, which is the most
efficient way to increase velocity. Maximum application time comes from
full range of motion. Example, Nolan Ryan has 180 degrees range of
motion in picture above. This is the maximum possible. This means the
Catapult is set to its potential, arm all the way back. For this to
occur with a pitcher the hips must be pushed under the shoulders. The
only way to push the hips under the shoulders is extending the back leg
ankle, knee and hip flexor, also called Triple Extension, at the perfect
time. With hips all the way under the shoulders, the pitcher now has
reached his full range of motion, therefore increasing the application
time to build or maintain force to the ball.
If the hips are
lagging, the chest is leaning forward and the arm is leading the body,
then minimal application time has occurred. Less range of motion
therefore less potential to create more velocity.
Triple
extension adds force to the ball because it aids in the momentum
originally generated from the lift leg along with gravity. This only
aids the momentum, if triple extension occurs, just before front foot
strike. If it happens to early and the hips have not moved down the
mound, then the hips open too soon. This kills the purpose of good
momentum and it also kills full range of motion.
With chest
out and hips under shoulders, chest and chin must remain up until launch
of ball to keep pivot stable through entire delivery.
More benefits of Olympic lifting!
Not
only do these lifts train Triple Extension better than any other style
of lifting but it specifically trains fast twitch muscle fiber. This is
what makes an athlete explosive. For pitchers and baseball players,
getting stronger in the weight room has been forbidden, until the
steroid area came into fruition. Now everyone is lifting. This isn't a
trend. This is because it works!
The last benefit of Olympic
lifting for the pitching delivery occurs during stabilization of the
front leg. Like described in the Catapult Theory, stabilization must
occur to prevent decreasing force applied to ball. Therefore if the
pitchers landing leg moves forward or gives away, then force is
decreased to the ball. In return poor velocity. Notice Nolan Ryan in the
picture here. His front leg almost triple extends. This means he is
preventing instability in his front leg by holding and even extending it
back into his hips. This is why he reached his top velocity.
So how do I get started?
In
the weight room but first find a professionally certified Olympic
Lifting Coach. These lifts take a lot of training to perform correctly,
so to prevent injury. I do not recommend performing these lifts with out
a proper coach supporting you. Please check with your physician before
performing these lifts and remember weight is not important. Your form
in the weight room and on the field is all that matters. Always
sacrifice weight for good mechanics.
