2. Mechanics Mechanics is the branch of physics that studies the motion of objects and the forces that cause that motion., but the three main areas most relevant to biome­chanics are: 1. Rigid-body 2. Deformable-body 3. Fluid

3.  Rigid-body mechanics, the object being analysed is assumed to be rigid and the deformations in its shape so small they can be ignored. Rigid body mechanics

4.  Deformable-body mechanics studies how forces are distributed within a material, and can be focused at many levels (cellular to tissues/organs/ system) to examine how forces stimulate growth or cause damage. Deformable-body mechanics

5.  Fluid mechanics is concerned with the forces in fluids (liquids and gasses). A biomechanist would use fluid mechanics to study heart valves, swimming, or adapting sports equipment to minimize air resistance. Fluid mechanics

6.  Kinesiology is a combination of the Greek for 'to move' (kinein) and 'logos' (discourse).  Science of human movement. kinesiology

7.  It is usually accepted that Aristotle (384-322 B.C.) is the' ''Father of Kinesiolgy". kinesiology

8.  The study of the structure and functions of biological systems by means of the methods of mechanics Hatze, 1974 We might think of biomechanics as the “physics of human movement” Biomechanics

9.  skill analysis  correction  pinpointing errors  developing a new technique  adapting to new equipment  understanding complex movement behavior Why study biomechanics?

10.  Improving Sports Performance  Better technique & training  Better equipment.  Sports Injury Prevention  Identifying safer techniques  Training to reduce risk of injury  Developing protective equipment (e.g. knee brace)  Occupational Injury Prevention (Ergonomics)  –(e.g. low back pain, hand & wrist trauma)  Injury Rehabilitation  – Identify when safe to return to activity What is Biomechanics Used For?

11.  Watch video Biomechanical facts

12.  Study of the description of motion, including considerations of space and time Kinematics

13.  Study of the action of forces Kinetics
