  • Impact loads - rearfoot striking

    After reading the responses I felt it was important to add in an other
    factor that was not considered but which plays a very important role in
    impact forces. It is running technique.

    For example, did the rear foot striker land with the leg extended well out
    in front of the body or was contact made as the leg was coming back so that
    the forefoot also made contact with the ground very quickly?

    Regarding the midfoot striker, was the midfoot contact achieved by bending
    the knee to land midfoot or was the leg straight in coming back and on
    contact?

    Re: the forefoot striker, was contact made well in front of the line of the
    CG or was it made under or close to being under the body. Did the runner
    land ball-heel or was there a distinct time difference between the ball
    touchdown and heel?

    As should be obvious in each of these scenarios the force generated will be
    different and the amount of force application will be substantially
    different. These are important factors to be considered.

    They can also answer many of the questions raised and can help explain some
    of the quantitative and qualitative differences created
