  • Anthropometric scalability question - Push/Pull Forces


    A colleague and I are working on a project to try to understand a
    comfortable range of push/pull forces that a 5th percentile female can
    endure. We have found many tables of forces published by many individuals
    mostly to do with maximum endurance forces for various push/pull
    exercises. We found a decent representation of our application in
    Dreyfuss' "Measure of Man and Woman". However, the forces given are for a
    50th percentile male. Dreyfuss gives a male to female scaling factor of
    2/3; we've also seen scaling factors around 1/2. We are interested in the
    5th percentile female as I have mentioned.

    Is there any such scaling factor/conversion that can take data (in
    particular push/pull forces) from one segment of the population (based on
    percentile) to another (e.g., is there a conversion to take data from 50th
    percentile to 5th percentile)?

    Short of doing our own study, is there a better way to get the data more
    directly? For instance, is there a more gold-type standard/study of
    push/pull forces for various exercises (i.e., forearm/shoulder in
    different orientations; sitting versus standing, etc.)?

    A summary of responses will be posted. Please indicate if you would like
    your name removed from the summary posting.

    Thank you for any information.
