Principles Of Human Locomotion

This book addresses how the general principles of biology influence the human capacity for locomotion, and, conversely, how understanding the nature of muscular activity might provide insights into the basic nature of living beings. Through a series of essays, the book relates the evolutionary basis of animal locomotion to recognizing the determinants of exercise capacity. While raising more questions than providing answers, the discussions will assume that without knowing the correct questions to ask, the answers will not be forthcoming. At the root of this book lies the central query: what is it that separates the principles governing the function of living beings from those that dictate the inanimate world? The discussions here address this issue from the expectation that clues to the answer can be obtained through understanding adaptations to the stresses imposed by physical exercise. As such, the book provides thought-provoking analyses of the biological basis of locomotion that will stimulate future efforts to understand these phenomena.

How can geckoes walk on the ceiling and basilisk lizards run over water? What are the aerodynamic effects that enable small insects to fly? What are the relative merits of squids' jet-propelled swimming and fishes' tail-powered swimming? Why do horses change gait as they increase speed? What determines our own vertical leap? Recent technical advances have greatly increased researchers' ability to answer these questions with certainty and in detail. This text provides an up-to-date overview of how animals run, walk, jump, crawl, swim, soar, hover, and fly. Excluding only the tiny creatures that use cilia, it covers all animals that power their movements with muscle--from roundworms to whales, clams to elephants, and gnats to albatrosses. The introduction sets out the general rules governing all modes of animal locomotion and considers the performance criteria--such as speed, endurance, and economy--that have shaped their selection. It introduces energetics and optimality as basic principles. The text then tackles each of the major modes by which animals move on land, in water, and through air. It explains the mechanisms involved and the physical and biological forces shaping those mechanisms, paying particular attention to energy costs. Focusing on general principles but extensively discussing a wide variety of individual cases, this is a superb synthesis of current knowledge about animal locomotion. It will be enormously useful to advanced undergraduates, graduate students, and a range of professional biologists, physicists, and engineers.

This book addresses instruments, methodologies and diagnostic methods used to evaluate and diagnose human movement, locomotion and physical status in general. Starting from historical perspective, the idea of understanding human locomotion by applying technical measurement devices and incorporating measurement data into physical representation of gross body movement is presented and explained, an approach known as inverse dynamics. With this approach as a kind of umbrella concept, components of measurement systems including relevant signal and data processing methods are described. Modern instruments to capture body movement by measuring its kinematics, kinetics and surface electromyography (sEMG) are thus described; all systems being used dominantly—if not exclusively—in a movement analysis laboratory setting. Focusing mainly on human posture and gait, but including also examples of movement patterns from selected kinesiological and sports activities, the book attempts to present essentials of biomechanics and biomedical engineering approach to this subject matter. It illustrates how data collected and elaborated by modern engineering technology can complement traditional expert knowledge of a kinesiologist or a medical doctor. The book is applicable in the fields of sports, physical activities, as well as in medical diagnostics and rehabilitation. The examples of this book’s practical application might be in evaluation of efficiency of human gait, in evaluation of skeletal muscle fatigue in physical exercise, in biomechanical diagnostics of traumatological conditions requiring orthopaedic treatment and the like. This book can also be used in planning and executing research endeavours, particularly in a clinical context as a reference for various diagnostics procedures. It presents the lecture notes of a course carrying the same name within Medical Studies in English at the University of Zagreb for more than a decade.

The importance of measurements for the proper assessment of human locomotion is increasingly being recognized. The fields of application encompass both healthy and pathological locomotion as encountered in rehabilitation medicine, orthopedics, kinesiology, sports medicine, and the like. Measurement of Human Locomotion provides an up-to-date description of the instrument systems used for measurement of: kinematics of human movement; kinetic quantities experienced by the human body in contact with the ground; and, myoelectric changes associated with locomotor activity. Physical principles behind the operation of various measurement systems are emphasized, as well as signal processing issues that must be addressed in order to obtain and use quantitative measurement variables in biomechanics. The book explains how measurement data are acquired, processed and presented to the user in the environment of a modern, computer-based laboratory. The ultimate aim is to contribute to the processes of the diagnosis and treatment of locomotion disorders. The purpose of Measurement of Human Locomotion is to provide a concise but comprehensive presentation of the systems used for the measurement of human locomotion, with a view to the assessment and diagnosis of the phenomenon.

Origins and Principles of Clinical Biomechanics in Human Locomotion discusses key concepts of how biomechanics links to the development of pathology through mechanical laws, anatomy, physiology and health. It provides fundamental principles and practical data, and guidance of how to apply these in the clinical biomechanics field. Coverage includes: major joint movement, muscle action around joints, physiology and patho-physiology of bone, muscle and neurologic disorders. This reference is ideal for teaching students in biomechanics, orthopedics and physiotherapy. It should also be of interest to product development engineers, rehabilitation engineers, those working in prosthetics and orthotics, physiotherapists and occupational therapists. The authors explore the simple laws of motion as applied to anatomy and physiology, in order to help readers understand human pathology within the human lower limb and mobility. They then go on to look at materials science concerns within this field, such as engineering stresses and strains, principles and types of material properties and the shaping of structural properties. Readers will also find within this book information on tissue science, force generation, biological sciences, evolution in biomechanics, human gait, functional units of the lower limb and foot, and finally pathomechanical principles; all as applied to clinical biomechanics. Bridges the void between research biomechanics and clinically applied biomechanics Links human locomotive biomechanics to medicine, physiology and evolutionary anatomy and medicine Prepares students, bioengineers and clinicians for the reality of utilizing biomechanical principles in clinical practice, while informing researchers of the environment limits that most clinical biomechanics practice occurs in
