  • Re: question about the contraposto pose...

    I believe you should focus your attention on what happens in the flexed
    leg. There, the extensor muscles can relax completely, and the load on the
    foot can be decreased to almost zero.
    Since almost all of the static load is on the other leg, I believe in
    the hip and knee extensors on that "overloaded" side there must be a larger
    postural activity than in the standard symmetrical standing posture. There
    must also be much larger bone-on-bone forces at the joints. There might also
    be activity in the hip adductors, together with ligament stretching. These
    are all drawbacks.
    In my opinion, there can't be any reason for overloading one leg so much
    except that the extensor muscles on the other side can relax completely and
    bone-on-bone forces can be almost zeroed.
    Notice that in PROLONGED SYMMETRICAL STANDING the isometric postural
    contraction may hinder blood flux, particularly venous return. Also,
    bone-on-bone forces can reduce blood flux in the joint cartilages. Complete
    relaxation on one side can help to reduce idrodinamic and idrostatic blood
    pressure in the veins.
    I practice free climbing. Often, when you hold your weight with both
    hands on a rock and feel fatigued, it is convenient to leave one hand and
    hold yourself for a while with the other hand only, so that the finger
    flexors in the free limb can relax and recover from fatigue, due to larger
    oxigenated blood flux with consequent removal of CO2 and lactic acid...
    Weird, but it seems to work.

    Subject: question about the contraposto pose...

    Hi all,

    Maybe someone know the answer to a question I have. If you know someone
    that could help me, please tell me.

    I would like to know why people adopt the contraposto pose (like "David of
    Michelangelo") while standing.
    That is, a flexed leg and the body weight supported by the other leg.

    I want to know it because I'm interested in generate postures automatically
    and a standing person, sooner or later, will converge to this posture. I
    would like the reason
    that drive people to adopt this posture. In fact, my questions are:
    do we adopt this posture due to we are trying to find passive torque in the
    limit of the hip joint?
    In other words, Is it related to passive elastic joint moments obtained in
    the joint limit?
    I've read that passive elastic joint moment is produced only by a assisted
    movement (a second person
    forces the movement). Is it true?

    thanks in advance,
    Inmaculada (
