The Value of 3D Analysis To the left are two actual 3D analyses performed by ZenoLink (our 3D partner) on two very different hitters. The top illustration shows the swing of a 2015 MLB 1st Round Draft Pick. The bottom illustration is an average high school player. The horizontal axis of each diagram represents time – when each body segments activates (moves) in the swing. The vertical axis displays the speed of each body segment in degrees per second. The taller the line, the faster that body segment is moving.
By comparing the two profiles, we see EXACTLY how these hitters differ: Amateur swing:
The top player moves his body segments in a good sequence (from the ground up) Each body segment of the top player reaches its top speed before the next (higher) body segment does. The bottom player’s segments do not. The top player’s bat speed reaches 2100 degrees per second. The bottom player’s bat speed reaches only 1455 degrees per second. The top player makes contact with the ball almost instantly after reaching top bat speed. The bottom player makes contact later, after the bat has begun slow down significantly.
The value of 3D analysis versus 2D analysis is that there is no guesswork, and every movement is measured. By using these numbers, we can then also measure the improvements of our players!
