Title of Thesis/~issertation: Author : (signature ) (name ) (date) ABSTRACT An anthropometric human body composition method was designed t,o predict skin, adipose. muscle, bone and residual tissue masses in males and females aged from 6 to 77 years. Based on departures from a defined unisex reference human the design of the method had two constraints: (1'1 the sum of the predicted fractional masses was to approximate the individual obtained body weight in 11 samples representing a wide variety of human physique and. (2) the individual tissue masses and the sum was to be consistent with anatomical evidence from the dissection of 12 male and 13 female human cadavers. When applied to all living subjects (n= 1669) the standard error of est,imate (SEE1 for the prediction of body weight \vas 3.00kg and the correlation coefficient 0.087. with a tendency toward overprediction of the body mass by 1.. The SEE'S for the samples ranged from 0.97kg for female lightweight rowers to 2.94kg for males age 6-l7years. In 9 of the 11 samples the correlation coefficients ranged from 0.985 for girls aged 6-17 years to 0.931 for female university students. hlale and female lightweight rowers showed the lowest coridation (0.608 and 0.509 respect,ively). indicative of' the minimum variab1it.g in their body weight. The sum of the predicted fractional tissue masses accounted for total body weight within 4% across all samples with the exception of body builders. An 8% error in this group was attributed to their extreme physique and possible dehydration at the time of measuring. The performance of the method, which was developed independently of the cadaver sample, was generally superior to other- methods built and validated on the cadaver data. There exists potential for further refinement with computer optimization, augmented with medical imaging data and further cadaver evidence. iii DEDICATION To Jindrich Matiepka, in recognition of his legacy to the stud!. of human physique. it was a major loss for students of human physique that Matiegka's approach, providing physical anthropometry with its vital "fourth dimension" remained for years unnoticed (Brozek, 1960). ACKNOWLEDGEMENTS The emergence of kinanthropometrg as a scientific discipline has been largely due to the cooperation and sharing of ideas and data, as well as the rigorous attention to technique. I have benefited from the work of the many scientists whose past and present works on the structure of human physique has enabled the completion of this thesis. I am indebted to those who have contributed to the data assembly. Dr A. Martin, Dr D. Drinkwater and Dr M. Marfell-Jones provided anatomical dissection data from 25 human cadavers; without which it is unlikely that this thesis would have evolved to the present, form. Data assemblies on living subjects has been augmented by more than 30 kinanthropometrists. In particular, I would like to extend my sincere t.hanks to Dr E. DeRose for providing the opportunity to collect data. along with my colleague Susan Crawford, on lightweight rowing at the X Pan American Games. To my supervisory committee of Dr Tibbits, Dr Hedges and Dr Weldon you supportive approach and constructive suggestions certainly enhanced the final copy. A special thanks to Dr Weldon for helping make sense of the "numbers" For proof reading the earlier drafts of the thesis I would like to thank Susan, Wendy and Dr Hedges. Also I would like to thank George and Dale for their counsel on microcomputer difficulties. Without Shona. Cheryl and Laurie a graduate students life would be even more chaotic: thanks for all your help. To my colleagues Richard and Sue. your continuing support, suggestions and humour was always there when most needed. A special thank you to Mary for the practical suggestions and encouragement. Mum, Dad, Pete and Bron; there were times I doubted myself but you never did (or so you said!). Thank you for sharing my goals. For financial assistance I am indebted to the Rotary Foundation for providing the opportunity to study at. Simon Fraser University. I have greatly appreciated the support of my Rotary counsellors, Howard Stevenson and Ron Mitchell. To Dr W.D. Ross for your unfailing enthusiasm and for enlightening me to a "conceptual, theoretical, methodological and historical" view of science. TABLE OF CONTENTS ..
