Introductory Biomechanics book cover

Introductory Biomechanics

An interactive text ideal for all health and sports professional students who require a basic understanding of the major biomechanical principles they meet in practice, including movement analysis and tissue mechanics. Starting from the point of zero-knowledge, this book presents what can be a very dry and difficult area, in an engaging and visual way using everyday objects to illustrate the principles and linking this to human anatomy and movement . Less time is spent on mathematics and classic mechanics with greater emphasis on how these principles are applied to professional practice

Introductory Biomechanics uses workbook–style learning diffusing manageable chunks of theory with learning activities and ultimately making the link back to clinical application. The accompanying CD is closely tied in with the text, containing video clips and real motion analysis data of walking, jumping, cycling and rising from a chair. There are also numerous animations of principles in action. The user is in control of most clips and animations and can change settings and manipulate variables practically showing biomechanics in action. The CD also contains a dynamic quiz drawing randomly from a pool of over 70 questions (MCQs, fill-in-the-blanks, true/false) which also provides feedback and percentage score on completion.
