Finally, the elbow plays its role even though it is not built to rotate in this direction. This squares the pitcher's chest, shoulders and hips with the plate and starts to bring his throwing hand forward.

Second to last starts the shoulder rotation which significantly multiplies the forces of the kinetic chain.

Next, the pitcher moves into the balance position by lifting his left knee smoothly until it's level with his waist. (We will ignore rotational and potential energy for the purpose of focusing solely on pitch velocity.). If the ball reaches a speed of 94 mph (42 meters per second), the kinetic energy would be (0.5) (0.149 kilograms) (42 meters per second) (42 meters per second), or 131 joules. There is kinetic energy when the pitcher has thrown it or when one of the other players has thrown the ball. This rocks the body slightly back, although the pitcher's chin and glove remain centered over his right leg. This site uses Akismet to reduce spam. MacWilliams BA, Choi T, Perezous MK, Chao EY, McFarland EG. In my experience, this is the most common segment for kinetic chain breakage. For a 90 mph pitch (40.2 m/s), the ball’s energy needs to be 117.4 joules. 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. 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. Average Athlete Tips for Connecting the Kinetic Chain, Elite Athlete Tips for Connecting the Kinetic Chain. Developer of 3X Pitching, Retired Professional Pitcher, MLB Consultant and USAW Certified Sports Performance Coach. Studies show the maximum vertical ground reaction forces averaged 202 +- 43% BW approximately 45 milliseconds after stride foot contact. It just takes so much more energy to do it and the harder a pitcher throws, the more each addition mph costs. Baseball. This should also mean all injuries have been healed and repaired. Required fields are marked *. ... 3 Pitching Grips - How to throw the Sinker, Slider, and Forkball - Duration: 11:17. 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. 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. ( Log Out /  The rocker -- Now the pitcher takes a small step back with his left foot. Change ). His throwing hand now sits level with his hat, fingers on top of the ball. It is impossible to fix the kinetic chain if this base level of strength and even power have not been developed. The left foot, still off the ground, leads the body forward. Hand separation -- The balance position stores the pitcher's energy, much like a coiled spring. Simply put, do more work on the baseball to transfer a greater energy into it before it’s released.

I will also give you some tips to help fix this major issue, so you can become a high-velocity pitcher. Pathomechanics and its Effects on the Pitching Delivery, Top 10 Ways to Improve Pitching Mechanics, Triple Extension Pitching the Foundation of 3X Pitching, Study: Vertical Jump & More Increases Pitching Velocity. The healthy high-velocity pitcher more efficiently transfers forces from the ground up this kinetic chain. Studies have shown that the hand and ball velocity are due primarily to leg, hip, and trunk movement (1). Studies show push-off vertical forces are fairly constant, with peak magnitudes of slightl… 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. 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. Here is the sequence, forces, and speeds of movement up the kinetic chain that drive the high-velocity fastball. Studies show the elbow hinges toward the target at a velocity of approximately 4000 degrees/second. The kinetic energy from the pitch is then transferred to kinetic energy and gravitational potential energy as the ball flies through the air. 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. 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. Kinetic chain breakage can occur in the elite explosive athlete. Now let’s look at how the kinetic chain must function for the high-velocity pitcher. A correlation between braking force and ball velocity was evident (3). 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). The pelvis essentially pulls the trunk toward the target by leading the way (1). This slight rocking motion unlocks a flow of momentum and energy that cascades through the pitch. Change ), You are commenting using your Google account. Here is a perfect definition of this breakage: This kinetic chain ‘‘breakage’’ has been demonstrated in both young and older athletes in many anatomic areas and as a result of repetitive, vigorous activities. For a 90 mph pitch (40.2 m/s), the ball’s energy needs to be 117.4 joules. 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. Once the hips have fully opened the trunk then multiplies these forces. 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 . Each body segment accelerates in order from lower to higher. If the equation had been E = ½mv then the relation ship between energy put into the system and the velocity out would have been linear. Information about the device's operating system, Information about other identifiers assigned to the device, The IP address from which the device accesses a client's website or mobile application, Information about the user's activity on that device, including web pages and mobile apps visited or used, Information about the geographic location of the device when it accesses a website or mobile application. It all starts with the pitcher who transfers chemical energy from the food he eats into kinetic energy when he throws the ball. –, JOHN A. GUIDO, JR1 AND SHERRY L. WERNER2 –. This is 26.6% increase in energy input for only a 12.5% increase in velocity.

After the legs have generated the linear forces the hips to begin its contribution. Both feet rest on the rubber, about shoulder width apart. 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. ( Log Out /  For a pitcher to throw 80 mph (35.7 m/s), the ball needs to have 92.7 joules of kinetic energy at release. The fact that the “v” is squared in the kinetic energy equation makes all the difference.
