Biomechanics – What is it?Biomechanics – What is it?
• The mechanical bases of biological systems.
• The application of mechanical laws to living structures.

Biomechanics – What is it? (cont.)
Biomechanics – What is it? (cont.)
• The study of the structure and function of biological systems by means of the methods of mechanics.
• The science concerned with the internal and external forces acting on the human body and the effects produced by these forces.

Kinesiology – Is it the same as biomechanics?
Kinesiology – Is it the same as biomechanics?
• Kinesis (motion) + -logy (science, study of)
• Applied anatomy and mechanics• Rasch & Burke (1978). Kinesiology
=anatomy (science of structure)+physiology (science of body function)+mechanics (science of movement)= science of movement of the human
body.

Kinesiology (cont.)Kinesiology (cont.)
• Old (pre-1980) usage– Title of a functional (applied) anatomy
+ biomechanics course (“Kinesiology”).
• Continue to see that use– many programs now put extra
descriptors in the title for clarification (e.g., “Anatomical Kinesiology”, “Functional Anatomy and Kinesiology”).

Kinesiology (cont.)Kinesiology (cont.)• Current (post-1980) usage
– One of several terms used to characterize the discipline or field (e.g., “Department of Kinesiology”).
• Other terms include “Exercise Science and Physical Education”, “Exercise and Sport Sciences”, “Human Movement Studies”, or “Movement Science”.
– Potentially an umbrella term for any form of anatomical, physiological, psychological, or mechanical analysis of human movement.

improve functional movement capacity– study of natural and artificial biological
tissues

Why Study Biomechanics?Why Study Biomechanics?
• From a mechanical perspective…– How do we generate and control our
movements?– What mechanical and/or anatomical
factors determine or limit movement outcomes?
– How can we make our movements “better”?
