Whereas mechanics is the scientific study of bodies in movement and the effect of force upon that movement, bio-mechanics adds another dimension. It adds the study of biological systems, and using methods derived from mechanics, their structure and function.
This area of study can be traced back to Socrates, but it was Galileo who developed the discipline further laying the basis for what it is today: a study whose results are used for professions such as exercise and sports science, health sciences, ergonomics and human factors, as well as engineering. confusingly, Biomechanics is also the name of the Soviet Union's antirealistic system of dramatic production developed in the early 1920s.
