  • Kinetic CoM Calculation

    Hello All,

    I am trying to calculate the centre of mass of sprinters
    running over the first two steps after exiting the blocks. I
    am using kinetic data from 2 force plates, having only
    obtained force, moment and centre of pressure data collected
    at 990Hz. I have calculated the centre of mass using the
    kinetic double integration method considering the initial
    velocity and initial displacement to be zero. I used this
    method as it was described in the biomch L archives: Chris
    Kirtley’s - CoM from force plate: Summary of responses. The
    results I obtained seem unrealistic and I am having trouble
    interpreting them. I would very much appreciate any help
    with a correct method to use, how to calculate the
    integration constants (if they should be non-zero) and any
    information on what to expect or how to interpret them.
    Thanks for any help.
