5 application of mechanical principles to the study of living organisms BIOMECHANICS living organisms branch of physics description and causes of motion

6 Biomechanics: Does it exist in more than one field? Exercise and sport biomechanics Orthopedic biomechanics Occupational biomechanics Biomechanics of other biological systems

7 Biomechanics – Does it exist in more than one field? (cont.) Exercise and sport biomechanics –improving athletic performance, reduction of athletic injuries

8 Biomechanics – Does it exist in more than one field? (cont.) Orthopedic biomechanics –artificial limbs, joints, and orthoses to improve functional movement capacity –study of natural and artificial biological tissues

9 Occupational Biomechanics –Ergonomics and Human Factors –reduction of workplace injuries Biomechanics – Does it exist in more than one field? (cont.)

10 Biomechanics of other biological systems –Comparative biomechanics (e.g., swimming in fish, locomotion in apes) –Equine (horse) and canine (dog) racing performance Biomechanics – Does it exist in more than one field? (cont.)

11 What do we have in common? Application of fundamental mechanical principles to the study of structure and function of living systems. Common measurement and analysis tools.

12 What do biomechanists do? g Help improve sport performance. (e.g. somersault long jump) g Help understand injury mechanisms. (e.g. impact shock attenuation) g Design sport equipment. (e.g. running shoes)

13 What else do biomechanists do? g Design of workplace environments. (e.g. wrist pads for keyboards) g Improve efficiency of the workplace. (e.g. cockpit design) g Basic understandings of how the body produces motion. (e.g. joint power analysis)
