G'Day BIOMCH-L-ers,
Many thanks to all who responded to my query for information on human
arm mass moments of inertia.
My original request was :
I am seeking the mass moments of inertia (Ixx, Iyy & Izz) for the human arm,
forearm and hand segments as input to a 3-D kinetic model of throwing
activities.
What is the most reliable/useful source of this information ?
Thanks for sharing any information that you may have.
Numerous references to literature have been forwarded to me.
Gideon Ariel (ariel1@ix.netcom.com) very kindly provided me with a PC software
package (Ariel Anthro) which calculates various segment parameters.
Contact him directly if you are interested.
The other responses follow :

Hi Tim,
We've used the Yeadon and Morlock regression equations from their 1989
Journal of Biomechanics article, and been quite happy with those. Since
we're using it for simulation work, its not quite so critical that
inter-individual differences are catered for.... ie. I haven't done a lot
of validation comparisons.
Hope that helps.
Bob

Dear Dr. Barker,
There is an old, thin text (navy blue and red cover) titled something like
"On the Mass Centers of the Human Body" that I remember seeing in my
graduate work. I believe the author is German, and an extensive study (of
the limb moments of interia and mass centers) was conducted on frozen
sections of cadavers by suspending them from a string, then spinning the
limbs. There are several pictures of naked soldiers (with figleaves placed
in politically correct places) carrying weapons and backpacks. Perhaps
other researchers can identify the text from this description. Sorry I
can't be more specific.
Other possible references: Dempster et al, Clauser et al, and Zatsiorsky.
Good luck.
Sincerely,
Marc Ramer

Hello Tim,
I've recently completed my PhD focussing on the area of body segment
parameters (BSP) used in biomechanics. Unfortunately, there is no easy
answer to your question in terms of "reliable\useful". The works of
Dempster (1955) and Clauser et al (1969) is the most often used BSP; hence,
it may be the most "useful" since it is the default values most
biomechanists accept. "Reliable" BSP is another story. To my knowledge,
no one has directly investigated the reliability of BSP prediction
functions although many researchers have used cross-comparisons of
results. I would suggest the most "valid" BSP are those presented by
Zatsiorsky & Seluyanov in Biomechanics VIII-B pp. 1152-1159 (1983) and in
Biomechanics IX-B pp. 233-239 (1985) since they had a substantially large
number of subjects (n=100 males) and measured in vivo. More recently,
they have re-reported this information with supplementary data on 15
females (Z, S & Chugunova Biomechanics of Human Movement: Applicationin
Rehabilitation, Sports and Ergonomics, Berme & Capozzo (eds), 186-202,
Bertec Corp., Worthington, Ohio (1990). In addition, I would look at
Yeadon & Morlock (1989) study using non-linear functions (J. Biomech.
22(6/7):683-689, 1989. If you're looking for a more complete review of
BSP literature, I've recently published a survey of BSP research in
Sports Medicine 18(2);126-140, 1994.
Best of luck with your study!

Hi,
I don't know which source is the most reliable. That probably depends
on the research you are conducting. But I can tell you which source I
used in a 3-dimensional study of the speed-skating movement. Here it is:
McConville, J.T., Churchill T.D., Kaleps I., Clauser C.E., Cuzzi J.:
Anthropometric relationships of body and body segment moments of inertia
AFAMRL Technical Report 80-119, Wright-Patterson Air Force Base, Ohio, 1980.
Hope this will help...

Dr. Barker:
Saw your messege on the Internet this morning regarding moment of inertia
estimates for arm, forearm, and hand segments. One fairly complete data
base for mass and MOI estimates for many body segments (including these)
is included in the NASA-STD-3000 man-systems standards. I Don't believe
that their data was completely original in that they had simply compiled
information from many sources. Unfortunately, I don't have a complete
reference, but a partial one is listed below:
NASA-STD-3000, Man-Systems Integration Standards (MSIS), United States
National Aeronautics and Space Administration (NASA), date: ???
I suspect that your friendly librarian can track down the complete
citation through the U.S. Supervisor of Documents (SUDOC) catalogue.
Hopefully, it is still available.

Dear Dr. Timothy M. Barker:
The mass and moments of inertia (Ixx, Iyy, Izz) for the 10 segments of the
human body (including arm, forearm and hand) are defined by V.M. Zatsiorsky and
his postgraduate students. I think that this is most precisely what you are
looking for.
Most of these works were published in Russian. But some of them were published
in English and German.
