can you explain how to do this on excel step by step with images or diagrams You will need to compute the velocity and acceleration of the center of mass (CoM) position from the data. For ease of understanding, use the sacrum marker as a surrogate for the total body CoM. You will need to compute the velocity and accelerations in both the Y and Z planes for the duration of the movement. 1. Importantly, the data you receive is in millimeters (mm) so you will need to convert those data to meters (m) before computing anything. 2. For the vertical jump data, you will also need to compute the vertical jump height of your participant
