In Shaunta Grimes' middle-grade novel Center of Gravity, a girl loses her mom, and her dad remarries quickly, so she must rebuild her life and friendships. Tessa is an anxious person, but it's become worse since her mother died a few months ago. To calm herself down she cuts out photos of missing kids—from milk cartons—and keeps them in a file. It helps her feel like she's not alone. When her dad announces suddenly that he's getting married—and that they're moving, Tessa must navigate new friendships and a new stepmother. She knows she should let go of old habits, but that's easier said than done. Her struggle is one that many readers will understand.
Biomechanics of Sport and Exercise, Second Edition, introduces exercise and sport biomechanics in concise terms rather than focusing on complex math and physics. This book helps students learn to appreciate external forces and their effects, how the body generates forces to maintain position, and how forces create movement in physical activities.
"Data are presented concerning the location of the center of gravity of the adult male in various body positions and the ability to shift the c.g. voluntarily with various body motions. Maximum possible shifts of the c.g. from that of an erect standing posture were found to be 11 1/2 inches toward the head, 10 inches toward the feet, 8 inches anteriorly, 4 1/2 inches posteriorly and 4 1/2 inches laterally."--Abstract.
Smallholder farmers and pastoralists fulfil an invaluable yet undervalued role in conserving biodiversity. They act as guardians of locally adapted livestock breeds that can make use of even marginal environments under tough climatic conditions and therefore are a crucial resource for food security. But in addition, by sustaining animals on natural vegetation and as part of local ecosystems, these communities also make a significant contribution to the conservation of wild biodiversity and of cultural landscapes. This publication provides a glimpse into the often intricate knowledge systems that pastoralists and smallholder farmers have developed for the management of their breeds in specific production systems and it also describes the multitude of threats and challenges these often marginalized communities have to cope with.
Biomechanics applies the principles and rigor of engineering to the mechanical properties of living systems. This book integrates the classic fields of mechanics--statics, dynamics, and strength of materials--using examples from biology and medicine. Fundamentals of Biomechanics is excellent for teaching either undergraduates in biomedical engineering programs or health care professionals studying biomechanics at the graduate level. Extensively revised from a successful first edition, the book features a wealth of clear illustrations, numerous worked examples, and many problem sets. The book provides the quantitative perspective missing from more descriptive texts, without requiring an advanced background in mathematics. It will be welcomed for use in courses such as biomechanics and orthopedics, rehabilitation and industrial engineering, and occupational or sports medicine.
Approaching the subject of kinesiology from the perspective of occupational therapy, this unique text written by occupational therapists examines the everyday activities of people using the principles of biomechanics to adapt to changes in their functional abilities. This new edition stresses applicability to clinical practice with the inclusion of case examples. In-depth coverage of wrist and hand pathokinesiology, as well as normal kinesiology function of the wrist and fingers Key terms, chapter outlines, and applications that enhance studying and learning 12 appendices and a glossary with metric conversions, review of mathematics, a diagram of body segment parameters, and laboratory activities New material providing explanations of the pathokinesiology of shoulder subluxation, rotator cuff tear, adhesive capsulitis, fractures, tendon injuries, and shoulder problems secondary to CVA More case studies and less emphasis on heavy calculations to ensure the concepts are more easily grasped Perforated lab manual filled with activities tied directly to the chapters Enhanced illustrations for easier visualization of the concepts demonstrated
The contributors to this text explain how to collect, analyse and interpret various forms of biomechanical data. They cover an extensive range of topics including inverse dynamics, dynamometry, electromyography, modelling and simulation.
