Book excerpt: Biomechanics is the science that uses the first principles of physics for the study of the mechanics of biological systems. It touches on many areas of the natural sciences and ranges from investigations of the mechanisms of force production on the molecular level, to the optimization of the performance of athletes on the macroscopic level. In this text the authors provide a unique and comprehensive account of the mechanics of the neuro-musculoskeletal system. Geared towards students and researchers of biomechanics, the book covers key areas such as the properties of biomaterials, common measuring techniques and modelling.
