    Hello, I'm a new member to the list and new to Biomechanics. In fact I know
    hardly any biomechanics but I'm competent scientifically and am looking to
    learn something about the subject. Sorry for the long e-mail by the way.

    I am involved in researching and writing a large publication on the science
    of Badminton which will be made available for free on the web. This covers
    psychological, tactical, technical and physical aspects of the sport. I
    want to introduce some biomechanical concepts into the technical sections to
    provide a theoretical foundation. I have made a start on this but as my
    experience is pretty much zero I hope you could critique my work so I'm not
    heading off in the wrong direction. Ultimately I would like to do some
    controlled research to provide data where necessary.

    The document portion is at:
    (sorry no diagrams yet, I want to know I'm on the right track before jumping
    into Poser and CorelDraw)

    I doubt I'm 100 percent correct anatomically. For instance is limb right?
    Is a hand a limb, forearm, upper arm, etc...? I will correct these mistakes
    once I have learnt more. Also, I doubt my loose description of muscles
    occuring in pairs is right all of the time so that as well needs to be
    sorted but I think you can get an idea of what I'm trying to say in the

    The three main biomechanics type assertions I make are:

    1) decelerating movements are less controllable than accelerating or static
    velocity movements. This is something I feel intuitively so I would
    appreciate any pointers to research in this area. I did not find anything
    on Google.

    2) I did some thinking and came up with the solution of modeling movement
    around joints as a damped linear oscillator. Looking on google this appears
    to be a sound approximation but I didn't come across anything difinitive. I
    notice on Amazon that 'Fundamentals of Biomechanics' includes damped
    oscillators in its index so I presume I'm along the right lines.

    3) The lack of 'rebounds' (forced dampening) is detremental to the control
    and maximum speed of the shuttle impact. I have done some 'experiments' and
    this appears very much to be the case. However, I suppose it should be
    supported with data from controlled motion tracking experiments.

    I've been looking for books. Those that caught my eye were:

    * 'Fundamentals of Biomechanics: Equilibrium, Motion, and Deformation' by
    Nihat Ozkaya, Margareta Nordin
    * 'Human Body Dynamics: Classical Mechanics and Human Movement' by Aydin

    Any comments on these or other suggestions would be very much appreciated.

    Thanks for any help you can give.
