There are two forces that add velocity to a pitch:

Momentum

Rotational Torque

For momentum to effectively transfer to the ball, the pitcher must use all rotational pivots in order from the bottom up.  The hips must rotate before the shoulders and the shoulders before the arm internally rotates. For this to happen effectively these pivots must be free to rotate completely. Notice the picture of Tim Lincecum at the bottom of the page (Tim Lincecum is a phenom because of his size and ability to reach his top velocity continuously.)  Notice in the picture his weight is slightly leaning to his left. This would be like tilting an open door backwards so the open door slams closed due to gravitational forces. This gravitational pull is helping to create full range of motion in Tim Lincecum’s hips and shoulders at front foot strike. If he or the door was tilted the opposite way then these gravitational forces would work against his momentum by decreasing full range of motion in his rotational pivots. Using the force of gravity to increase the range of motion in your hips and shoulders will have a significant effect on your velocity. This is a big reason why Tim Lincecum can throw so hard for his size. He is working with the forces of nature to generate his power.

If you study the animated image here of Tim pitching you can see clearly the effective transfer of momentum through his rotational pivots. Watch his front leg land and his back hip rotate all the way around as his back leg triple extends. From here the momentum moves into the core because his front leg has stabilized  and his weight is being held back because his back shoulder is waiting for his hips to open to the target. This forces the core to tighten because the hips are rotating before the shoulders. His core looks like a rag being rung out or a rubber band being twisted at this point in the delivery. After this tightening of the core the momentum travels up into the shoulders. This torque pulls the back shoulder around and he sets the fulcrum, for the rotating shoulders, with his glove hand over his front leg.  The front leg continues to stabilize as his weight begins to shift over his front knee allowing the momentum to transfer into the final pivot. This is the shoulder pivot or the rotator cuff. Notice that when his trunk is fully forward, his arm is completely externally rotated. Now the arm fires like a rubber band and begins to rotate forward as also all the momentum from the body jumps into the ball like a passenger riding in a car and hitting a brick wall at 100 mph.

What Tim Lincecum continues to teach us is how to pitch with the entire body and that the arm is only along for the ride. This is exactly why little guys can throw so hard and old pitchers can still compete. Tim Lincecum uses gravity to aid momentum and his momentum to build torque in all of his rotational pivots. He also fires those pivots in the perfect order at the perfect time for effective momentum transfer. Everytime Tim Lincecum pitches, you should be watching because it is a lesson in Top Velocity.

If you are a tall and skinny freak who throws 90+mph then stop reading and have a great career. If you are like most of us, average in size and believe you have the potential to throw a lot harder without causing injury, then you must begin to learn what the strength and conditioning world has discovered.

The strength and conditioning profession has proven that pitching is an anaerobic exercise. An exercise that does not involve oxidation. The systems involved in creating energy for pitching, during the anaerobic exercise, are phosphagen and glycolysis systems. This is the use of creatine phosphate and sugars to make ATP (energy). What this means is, if a pitcher trains these systems in the off season then the muscles will develop more fast twitch muscle fibers to support the anaerobic exercise. More fast twitch muscle fibers means you have a higher capacity and storage of ATP. You also have the ability to recruit more muscle fibers, to add to the intensity of the workload. More muscle fiber recruitment creates more muscle strength during exercise. This increased muscle fiber recruitment during exercise causes more damage in the muscle during fatigue and in return promotes more testosterone to be released in the muscles to heal the damage tissue. This will build more muscle mass for future damage control. These side effects of high intensity anaerobic training, without a doubt, will lead to an increase in velocity. This is why pitchers who get bigger, stronger, faster, throw harder. When I say bigger, I do not exactly mean larger muscles like a body builder. I am talking about muscles that are more dense. A good example would be a light weight Olympic lifter. They look like little kids and can lift like machines.

I have dedicated this website to the secrets of velocity. They are velocity secrets because conventional wisdom doesn’t want you to know. Conventional wisdom sees pitching more as an art, instead of a science. If you have the desire to take it to the next level of pitching, you are going to have to overcome the old school techniques of coaching this position. You must learn the science of strength and conditioning for athletes. You must understand that if you need the most out of your body, you must learn what that is and what does it take. The first step in this process is questioning conventional wisdom and learning the science in everything you do. The next step is training fast twitch muscle fiber in the off season and maintaining the gains into the season. It isn’t an easy task but done correctly, it will mean the difference from a college career to a professional career.

I recommend the Ace Pitcher Handbook as an excellent off-season and in-season program that will promote fast twitch muscle fiber development.
