Impact forces feet can receive without get injured

  1. Jul 21, 2015 #1
    Hi guys,

    I have been searching for references that could tell what are the average limits of impact (in Newtons per example) of running activity into human´s feet (material = bone).
    Basically the question I am trying to answer is per example to understand how much of linear acceleration impact into a 70 Kg weight person´s feet during a certain amount of time is something good or not...

    Assumption formula: F = m * a
    // where :
    m = 70 Kg
    a = 2 * G = 2 * 9.8 = 19.6

    F = 70 x (19.6)
    F = 1372 N (so, suppose this Force is being applied to the feet during 10 minutes of running. Is this something good or will cause injuries to the person? Any clue?

    Thanks a lot !!
