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. This is the pivot, which turns the body so only the left hip and shoulder face the plate.

Kinetic chain breakage creates increased distal physiologic or biomechanical requirements (increased muscle activation or increased distal segment velocity, acceleration, or mass to ‘‘catch up’’ and develop the same kinetic energy or force at the distal segment); changes the interactive moment at the distal joint (increasing the forces that must be absorbed at the joint); or decreases the ultimate velocity or force at the distal segment.
The fact that the “v” is squared in the kinetic energy equation makes all the difference. 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. This is 26.6% increase in energy input for only a 12.5% increase in velocity. Here is the sequence, forces, and speeds of movement up the kinetic chain that drive the high-velocity fastball. 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. At the same time, the hands first separate, then move down, back and up like a pendulum. MacWilliams BA, Choi T, Perezous MK, Chao EY, McFarland EG.

However since the velocity is squared, it takes increasingly more energy input to get each additional mile/hour of pitch velocity (Figure 1). Since 2017 KineticPro Performance has been developing elite baseball players from the highest levels of the game. Taking a data forward approach KineticPro has aided players around the world in reaching their best on the field. Power slot position -- The pitcher plants his left foot in front of his body while the right foot remains situated against the rubber. 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. Studies have shown that the hand and ball velocity are due primarily to leg, hip, and trunk movement (1). 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.
