This guide describes 65 of the most effective exercises for strength, definition, and muscle size. Full-color anatomical illustrations show which muscles are being worked as well as proper alignment, positioning, and lifting techniques.
Skeletal Muscle Mechanics: From Mechanisms to Function summarisesthe variety of approaches used by today's scientist to understandmuscle function and the mechanisms of contraction. This bookcontains research by leading scientists from numerous fields usingmany different scientific techniques. Topics covered include: * Cellular and molecular mechanisms of skeletal musclecontraction * Historical perspective of muscle research * The newest developments in techniques for the determination ofthe mechanical properties of single cross-bridges * Theoretical modelling of muscle contraction and forceproduction * Multifaceted approaches to determine the in vivo function ofskeletal muscle This state-of-the-art account is written by internationallyrecognised authors and will be a valuable resource to researchersof biomechanics in sports science and exercise physiology. "I expect this book to be excellent and timely." Professor R.McNeill Alexander FRS, School of Biology, University of Leeds, UK
Two important goals of ergonomics are the comfort, and the health and safety of workers. In many ways these are mutually compatible, for where health and safety is jeopardized, the discomfort results. Most work-related injuries can be viewed as biochemical damage to a tissue or organ; ultimately all injuries are sustained by tissues. Written by leaders in the field, this text deals systematically with the biomechanics of tissues and organs in the workplace. The book establishes a foundation for the understanding of gross biomechanical loads on the human system at tissue level. It also provides details of the biomechanics of organs, themselves a composite of different tissues, and the differential effect and vulnerability of structures of the organ. Finally, the whole body system is dealt with in a biomechanical context. This text is a thorough description and discussion of common or work-related injuries, their mechanisms and the theories behind them. Chapters provide ergonomic relevance, ergonomic scenarios, and practical ergonomic advice on appropriate interventions.
Cardiac Dynamics is the name of a relatively young field of study, born from the fruitful interaction between branches of two different disciplines: medicine and physics. "Dynamics" is the branch of physics which deals with the action of forces on bodies or particles in motion or at rest. "Cardiac" relates to the clinical field of cardiology but also to cardiophysiology, both of which are specialized branches of medicine. Narrower than the well established field of Hemodynamics, Cardiac Dynamics is restricted to dynamic phenomena occurring in and around the heart. The mathematical treatment of such phenomena, however, is vastly more complex because of the intricate nature of the mechanisms involved in the cardiac action. Thus, whereas hemodynamics is concerned with predominantly passive (visco-) elastic structures - vessels - containing time-variant flow of viscous flui- blood -, the mechanical study of the heart requires additional con siderations such as: active elastic components representing the contractile mechanism of cardiac muscle, complex geometry and fiber structure in the myocardial wall, autoregulatory mechanisms, and intricate flow patterns associated with valve motion. Viewed in this light it is not surprising that attempts to describe ventricular pump function and to quantify contractile performance have not reached the level of sophistication which is common in e. g. arterial hemodynamics. For the same reason, many of the often simplified approaches to describe ventricular mechanics failed to stand up to more rigorous theoretical, experimental or clinical testing.
This is an introductory level textbook for students who are interested in understanding mechanical properties of smooth muscle, a vital tissue that is instrumental in many organ functions such as blood pressure control, intestinal peristalsis, and emptying of a bladder. Dysfunction of the muscle has been implicated in many diseases such as high blood pressure, asthma, and overactive bladders. This is the first book-length treatment of functional models of a variety of smooth muscle behaviors with mathematical description. No prior knowledge of muscle physiology is required. An easy-to-follow, step-by-step mathematical derivation helps students to appreciate the muscle cell as a fine-tuned aggregate of mechanisms governed by fundamental laws of physics. This book is useful for students and researchers in life sciences who are interested in the basic mechanism of muscle contraction or who simply use the tissue as a tool in their investigation. Besides a detailed description of the known subcellular structure and mechanical function of the contractile apparatus of smooth muscle, it also covers experimentation techniques, instrumentation, and data analysis, a must-have information source for anyone interested in smooth muscle cell physiology.
This book describes the evolution of ideas relating to the mechanism of muscular contraction since the discovery of sliding filaments in 1954. An amazing variety of experimental techniques have been employed to investigate the mechanism of muscular contraction and relaxation. Some background of these various techniques is presented in order to gain a fuller appreciation of their strengths and weaknesses. Controversies in the muscle field are discussed along with some missed opportunities and false trails. The pathway to ATP and the high energy phosphate bond will be discussed, as well as the discovery of myosin, contraction coupling and the emergence of cell and molecular biology in the muscle field. Numerous figures from original papers are also included for readers to see the data that led to important conclusions. This book is published on behalf of the American Physiological Society by Springer. Access to APS books published with Springer is free to APS members.
