Linear wrist velocities at ball release correlate highly with maximal posterior push-off shear force, a representation of “leg drive,” indicating that forces generated early in the pitching cycle with the lower extremities contribute to the throwing velocity (2). This is 26.6% increase in energy input for only a 12.5% increase in velocity. Now that we know the process of generating and transferring forces up the kinetic chain of the high-velocity pitcher lets look more into what breaking this chain does to the results and how to overcome and fix these issues. Mechanical work is defined as the energy transferred into a system through a force, such as when a pitcher applies force to a baseball to accelerate it towards home plate. The formula for kinetic energy is KE=1/2(mass)(velocity)^2, therefore 15 lbs travelling at 100 MPH has a kinetic energy of 5,012 ft lbs or more than twice that of the bullet! The major challenge of becoming a high-velocity pitcher is once the elite explosive power has been developed, if there isn’t fluid timing of the kinetic chain then this elite athleticism isn’t being converted into ball speed.
Physicists would use the following formula: K = 0.5mv 2 where K is kinetic energy, m is the mass of the baseball and v is its velocity. Studies show the shoulder at its peak rotates at approximately 7000 degrees/second, pulling the elbow toward the target. Learn how your comment data is processed. In baseball there are lots of different kinds of energy and and more then one energy system at work in a single at bat. So what does this figure mean in regard to pitching at a high velocity? The fact that the “v” is squared in the kinetic energy equation makes all the difference.
The pelvis essentially pulls the trunk toward the target by leading the way (1). To unleash that energy, the pitcher drives forward with his right leg and hip.

It just takes so much more energy to do it and the harder a pitcher throws, the more each addition mph costs.
This squares the pitcher's chest, shoulders and hips with the plate and starts to bring his throwing hand forward. Weird & Wacky, Copyright © 2020 HowStuffWorks, a division of InfoSpace Holdings, LLC, a System1 Company.
The tremendous difficulty to produce this magnitude of energy is a main reason that high velocity pitchers are one of the most sought after commodities in professional sports. This is 26.6% increase in energy input for only a 12.5% increase in velocity.
The Kinetic Chain is the link of joints starting with the ankle connecting to the knee, to the hips, to the shoulders, to the elbow and finally to the wrist. The kinetic energy from the pitch is then transferred to kinetic energy and gravitational potential energy as the ball flies through the air.
( Log Out / Both feet rest on the rubber, about shoulder width apart. Each body segment accelerates in order from lower to higher. For a 90 mph pitch (40.2 m/s), the ball’s energy needs to be 117.4 joules.
Simply put, do more work on the baseball to transfer a greater energy into it before it’s released. Those who are at either the base or elite level and looking to more quickly master the kinetic chain I would highly recommend attending a 3X Velocity Camp. The square position -- With his left foot firmly planted, the pitcher rotates his hip and trunk by turning on the ball of his right foot.

The reason I made the point in the beginning of this article about how important it is to develop the base strength of the high-velocity pitcher because the pitcher will always have a break in the kinetic chain until there are no issues of muscle weakness or imbalances, muscle inflexibility or joint stiffness, as stated in the excerpt above.
This is the pivot, which turns the body so only the left hip and shoulder face the plate. Now let’s look at how the kinetic chain must function for the high-velocity pitcher.
Each lags behind the adjacent lower segment, then accelerates past it at even higher velocity. First, the drive leg starts the process with its ground reaction forces. (We will ignore rotational and potential energy for the purpose of focusing solely on pitch velocity.). Studies show the trunk rotates at 1000 degrees/second, pulling the shoulder toward the target (1). Since the mass of the baseball is constant, the only variable we can manipulate to affect velocity is energy, and therefore, more energy in = more velocity out. Studies show the maximum vertical ground reaction forces averaged 202 +- 43% BW approximately 45 milliseconds after stride foot contact. The pivot and balance -- The pitcher transfers weight again by making a small turn with his right foot to place it parallel with the rubber. I will break these tips into two sections. In these cases, it has a lot to do with the challenges of working with limited ranges of motion with the body segments.
Kinetic chain breakage can occur in the elite explosive athlete. Second to last starts the shoulder rotation which significantly multiplies the forces of the kinetic chain.

For a pitcher to throw 80 mph (35.7 m/s), the ball needs to have 92.7 joules of kinetic energy at release.
Here is the sequence, forces, and speeds of movement up the kinetic chain that drive the high-velocity fastball. Checkout some of these testimonials, 3X Pitching Grips with MLB Pitcher David Aardsma, Top 10 Reasons You Need an Off-Season Pitchers, Top 10 Secrets to Getting Drafted as a Pitcher. Now let’s look at how the kinetic chain must function for the high-velocity pitcher.
Change ), You are commenting using your Google account.
Finally, the elbow plays its role even though it is not built to rotate in this direction.
It is usually acquired and can be created from many factors – remote injury, incompletely healed or rehabilitated injury, muscle weakness or imbalance, muscle inflexibility or joint stiffness, or improper mechanics. It all starts with the pitcher who transfers chemical energy from the food he eats into kinetic energy when he throws the ball. His left arm is bent at the elbow, with the gloved thumb pointing to the ground. This is why taller pitchers have the advantage in this skill. Studies show push-off vertical forces are fairly constant, with peak magnitudes of slightl… But the kinetic energy equation gives us an interesting insight into why it is so hard to throw at elite velocities (90 mph+). Power slot position -- The pitcher plants his left foot in front of his body while the right foot remains situated against the rubber.
Starting position -- The pitcher stands tall, with his body facing the plate and his glove, concealing the ball and throwing hand, tucked just below the chin. Your email address will not be published. The baseball also has kinetic energy when the batter hits the ball.
Kinetic Energy in Baseball David Ross. He makes the throw by whipping his right arm from 11 o'clock to 5 o'clock and then following through so that his right foot touches down with his body square to the plate, ready to field a ball batted directly back. Average Athlete Tips for Connecting the Kinetic Chain, Elite Athlete Tips for Connecting the Kinetic Chain. I will also give you some tips to help fix this major issue, so you can become a high-velocity pitcher. Studies show the pelvis rotates at 600 degrees/second, starting before trunk rotation. In this article, I will define how force is moved up the kinetic chain of the high-velocity pitcher. Now that we know what causes the breaks in the chain for all levels of pitchers here are some tips to help overcome these critical issues which are retarding the development of the high-velocity pitcher. A correlation between braking force and ball velocity was evident (3). How can a pitcher throw harder?
This slight rocking motion unlocks a flow of momentum and energy that cascades through the pitch. Next the landing leg contributes its ground reaction forces. Both hands should still be together and located close to the body, under the chin.
Required fields are marked *. First, the drive leg starts the process with its ground reaction forces.
The diminishing returns of velocity with regards to energy input into the baseball is a big reason why there are plenty of high school pitchers who throw 80 mph but only a small percentage of athletes will ever touch 90. It is impossible to fix the kinetic chain if this base level of strength and even power have not been developed. Those for the average athlete and those for the elite athlete.

Studies show push-off vertical forces are fairly constant, with peak magnitudes of slightly more than 1.0 body weight (BW) occurring early in the pitch cycle.
It is a lot harder to time all of these complex movements of the high-velocity pitching delivery, which takes less than 1 second to perform when you have even less time due to the short ranges of motion. This is why it actually losses speed from the shoulder rotation speeds. For a 90 mph pitch (40.2 m/s), the ball’s energy needs to be 117.4 joules. That is a more detailed definition of the kinetic chain and its importance to the athlete. ( Log Out / With 373 career wins, something about Hall of Famer Grover "Pete" Alexander's windup sure worked well for him. The term ‘‘kinetic chain’’ refers to the conceptual framework for understanding the mechanisms by which athletes accomplish the complex tasks required for function in sport . The delivery -- Finally, the pitcher drives his right leg forward, which rotates his hip around his front leg.
Here is the sequence, forces, and speeds of movement up the kinetic chain that drive the high-velocity fastball. The healthy high-velocity pitcher more efficiently transfers forces from the ground up this kinetic chain.

The kinetic energy of the baseball and its linear velocity are related by the well-known equation for kinetic energy: E = ½mv2. At the same time, the hands first separate, then move down, back and up like a pendulum. 99% of pitchers coming into the 3X Pitching Velocity Programs are at this base level but are trying to train above it. Your email address will not be published.
The process of becoming a high-velocity pitcher must first come with the development of a base foundation of total body strength and then power. –, JOHN A. GUIDO, JR1 AND SHERRY L. WERNER2 –.
