The Kinematic Sequence (KS) describes the joint positions during a hitters swing event. As the hitter sets up Pre-Pitch the hitter creates joints positions based on their individual posture (Hip Hinge) and tension (Biotensegrity). As the hitter moves into their final trailside loaded or negative move the hitter’s KS will move in a certain order. The ideal order is Hip – Chest – Bat. As the hitter Floats at Pitch – Release the joints do not change their position in space.
The hitter’s KS chain will accelerate and decelerate during the launching of the bat. The acceleration and deceleration event allows the hitter to transfer their kinetic energy up and through each joint. The purpose is to maximize the joint energy transfer to gain joint speeds and to maintain balance during the launch event. As a player understands their body they can then identify which joints and how much tension each joint needs to maintain their posture, connection with the ground, and pre disassociation between their pelvis and shoulders.
