Biomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, using the methods of mechanics. It is a branch of biophysics.
The study of biomechanics dates back to ancient Greece with the work of Aristotle, who wrote the first book on the motion of animals. The modern field of biomechanics emerged in the 19th and 20th centuries with the development of new technologies for measuring and analyzing motion.
Biomechanics is a diverse and interdisciplinary field with applications in a wide range of areas, including sports science, ergonomics, and rehabilitation. For example, biomechanics is used to design more efficient running shoes, to improve the safety of workplaces, and to develop better prosthetic limbs.
