View Full Version : Critique requested

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: www.martinwells.com/Badmintology/Technique.htm
(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.
