Thanks to all who replied with regards to my research. Here is a list of
the replies received:


We (Raul Landeo) and I have been doing some work on segment interactions
during kicking tasks (Bandal Chagui in Taekwondo). I suggest that you
contact Raul directly. I am presenting this material at the NACOB
meeting next month in Waterloo and we have a 2 page paper that you are
welcome to look at. Please ask Raul to send you an electronic copy of
it.

Cheers,

Rob

I am a practitioner of the martial arts (over 18 years of it) and I am
extremely interested in the biomechanics behind many of our techniques,
especially in the generation of power in many of the kicks. Could you
please
forward any comments on your inquiry to me?

Thanks,
George Calisto, CPE, CSP

I have not seen any articles on the specific kicks you have mentioned.
However, you might try the following sources for reference on related
methodologies:

Freund, R. "Karate Techniques: Applied Physiology and Biomechanics"
Journal of Asian Martial Arts 5:3.

Niiler, T.A. (1998) "Landing Impact Loading and Injury Risk to the
Lower Legs in Chinese Wushu" Journal of Asian Martial Arts 7:2 pp.
55-73.

In addition to giving methodologies, these papers have a large list
of references at the end which you might find useful. If your library
does not carry this periodical, contact Via-Media Publishers through
their web site:

I utilized the impact on the ground as my initial point at which to
begin the analysis, although I collected data throughout the jump
kicks. A couple of event markers strike me as being significant in your
case. The first is when the support foot first touches the ground. You
could start your subjects by stepping onto a force plate (or by using a
foot switch to tell ground contact) and follow the kick from that
point. So if the left leg was to kick, the subject would step onto
his/her right and then spin. This sort of set-up will give you
kinematic information over the entire kick. If on the other hand, you
are focussing on the contact point only, I would look at data from the
point at which the shoulders are in-line with the target. In my
experience, this event slightly precedes impact. However, unless you
have a very good frame rate, your resolution of this will not be
terribly good, since the time between the positioning of the shoulders
and the actual contact point is quite small.


I hope this is helpful.

Cheers,
Tim Niiler

Please look for Dr. Yoshifuku's papers. He is famous for his martial
arts
study in Japan and the world. He is also martial arts athlete and
specialist of physics.
And I did some martial arts experiment last year, my subjects were two
World Karate heavy weight champion, Mr. Yamaki and Mr Fillio.
If you want to get their data about kick trials,don't hesitate to
contact
me. I will send electrical data.
But these data has not published yet.

Best regards,

Andrew,
I am a practitioner of both kickboxing (karate based) and
Taekwon-Do and in addition i am also a Ph.D. student in Biomechanics.
Although i have not studied the biomechanics of any martial arts
techniques i am very interested in this area and as such would be
interested in your findings. However, from my own studies i would
recommend that you gain some (although you may have already done this)
background knowledge on sequential segmentation i.e. Kinetic-link
theory,
summation of speed principle, there are many articles on this area, in
particular i recommend searching for work by Carol Putnam, if required i
could forward you further details of literature related to this area.

All the best
