  • children and lifting

    Children, at least occasionally (and possibly often), carry objects which
    are, for them, relatively large and/or heavy (such as equipment and
    furniture) when at home, at play, at school, at sport, and probably other
    venues. However, there seems to be a dearth of information on functional
    lifting capacities for children and on the relationship between lifting and
    injuries in children.

    The only two sources relating to "lifting capacity" that I've found so far,
    data from which are reported in the UK Dept. of Trade & Industry "Childata"
    database, are :

    Owings et al (1977) Gripping strength measurements for children for product
    safety design. US CPSC Report 014926-F

    McClelland & Thompson (1976) Ergonomic data for evaluation and specification
    of operating devices on components for use by school children. UK Research
    Institute for Consumer Ergonomics; Report 75/2/21.

    As is obvious from their titles, they are not very specific to "whole body"
    manual lifting and carrying, and report only the relatively isolated
    "lifting" actions such as might be employed when operating a lever or
    handle. Also, as I imagine those reports are not readily obtainable, little
    information is available on the methodology employed.

    A additional consideration in children, especially the younger age groups,
    is their immature motor control in general and, in particular, for bimanual
    load lifting tasks. I have so far only found one paper relating to this
    aspect :

    Schmitz, C. et al (1999) Development of anticipatory postural adjustments in
    a bimanual load-lifting task in children. Exptl Brain Research, 126(2),

    Does anyone know of any sources of information on lifting
    strengths/capacities for young children? Does anyone know of any studies on
    load lifting in children from a motor behaviour/control/learning

    I will post to the list a summary of any replies and reference sources
