Book Description
This is another classic contribution by Braune and Fischer to the field of biomechanics. The pendulum method was employed to ascertain ac curately the moments and radii of inertia of the human body and its different parts about all axes - transverse, oblique or longitudinal. This elegant method is described in detail, together with the results. Relations were found between the centres of inertia on one hand and the lengths and diameters of the body segments on the other. These data were originally prepared for the authors' later work, The Human Gait, to determine the forces exerted on and by the parts of the body during walking. Such work is the basis for solving the mechanical prob lems related to any movement of the human body: thus, the original results presented here continue to be of im mense value to current research and practice.

Book Description
"A mathematical model for predicting the inertial properties of a human body in various positions was developed. Twenty-five standard anthropometric dimensions are used in the model to predict an individual's center of gravity, moments and products of inertia, principal moments, and principal axes. The validity of the model was tested by comparing its predictions with experimental data from 66 subjects. The center of gravity was generally predicted within 0.7 inches and moments of inertia within 10 percent. The principal vertical axis was found to deviate from the longitudinal axis of the body by as much as 50 degrees, depending on the body position assumed. A generalized computer program to calculate the inertial properties of a subject in any body position is presented. The inertial properties of five composite subjects in each of 31 body positions is offered as a design guide. IBM 7094 digital computer programs are appended."--Abstract

Book Description
The different chapters of the present book were published separately each as a complete entity in the Proceedings of the Royal Saxon Society for Sciences. Chapter 1 appeared in 1895 under the names of Wilhelm Braune and Otto Fischer although Braune died immediately after the initial experiments, before the recordings had been interpreted. Chapters 2-6 were signed by Fischer only and appeared in 1899, 1900, 1901, 1903 and 1904. Basic data needed for this investigation of the human gait had been provided previously. A research on the centre of gravity ofthe human body and its different segments by both authors was published in 1889, determination of the moments of inertia of the human body and its segments in 1892. So far only the fIrst of these two works has been published in English. The other has been translated and awaits publication. Springer-Verlag must be congratulated for the quality of this edition and for the care they took in reproducing the original fIgures. This was certainly no easy task. We thank them for the patience they displayed towards the translators. Publication of the present book was made possible fInancially by Prof. M. Muller, Bern. We are grateful to him for his generosity and so will be the scientifIc community.

Book Description
This book comprehensively addresses the physics and engineering aspects of human physiology by using and building on first-year college physics and mathematics. Topics include the mechanics of the static body and the body in motion, the mechanical properties of the body, muscles in the body, the energetics of body metabolism, fluid flow in the cardiovascular and respiratory systems, the acoustics of sound waves in speaking and hearing, vision and the optics of the eye, the electrical properties of the body, and the basic engineering principles of feedback and control in regulating all aspects of function. The goal of this text is to clearly explain the physics issues concerning the human body, in part by developing and then using simple and subsequently more refined models of the macrophysics of the human body. Many chapters include a brief review of the underlying physics. There are problems at the end of each chapter; solutions to selected problems are also provided. This second edition enhances the treatments of the physics of motion, sports, and diseases and disorders, and integrates discussions of these topics as they appear throughout the book. Also, it briefly addresses physical measurements of and in the body, and offers a broader selection of problems, which, as in the first edition, are geared to a range of student levels. This text is geared to undergraduates interested in physics, medical applications of physics, quantitative physiology, medicine, and biomedical engineering.

Book Description
The classic book on human movement in biomechanics, newly updated Widely used and referenced, David Winter's Biomechanics and Motor Control of Human Movement is a classic examination of techniques used to measure and analyze all body movements as mechanical systems, including such everyday movements as walking. It fills the gap in human movement science area where modern science and technology are integrated with anatomy, muscle physiology, and electromyography to assess and understand human movement. In light of the explosive growth of the field, this new edition updates and enhances the text with: Expanded coverage of 3D kinematics and kinetics New materials on biomechanical movement synergies and signal processing, including auto and cross correlation, frequency analysis, analog and digital filtering, and ensemble averaging techniques Presentation of a wide spectrum of measurement and analysis techniques Updates to all existing chapters Basic physical and physiological principles in capsule form for quick reference An essential resource for researchers and student in kinesiology, bioengineering (rehabilitation engineering), physical education, ergonomics, and physical and occupational therapy, this text will also provide valuable to professionals in orthopedics, muscle physiology, and rehabilitation medicine. In response to many requests, the extensive numerical tables contained in Appendix A: "Kinematic, Kinetic, and Energy Data" can also be found at the following Web site: www.wiley.com/go/biomechanics

Book Description
This is the first textbook to comprehensively cover the experimental methods used in biomechanics. Designed for graduate students and researchers studying human biomechanics at the whole-body level, the book introduces readers to the theory behind the primary data collection methods and primary methods of data processing and analysis used in biomechanics. Each individual chapter covers a different aspect of data collection or data processing, presenting an overview of the topic at hand and explaining the math required for understanding the topic. A series of appendices provide the specific math that is required for understanding the chapter contents. Each chapter leads readers through the techniques used for data collection and processing, providing sufficient theoretical background to understand both the how and why of these techniques. Chapters end with a set of review questions, and then a bibliography which is divided into three sections (cited references, specific references, and useful references). Provides a comprehensive and in depth presentation on methods in whole-body human biomechanics; First textbook to cover both collection and processing in a single volume; Appendices provide the math needed for the main chapters.
