4. Kinematics: study of the variables that describe or quantify motion Displacement Velocity Acceleration Kinetics – study of the variables that cause or influence motion Forces Torques Mass

5. Problems studied by biomechanists Biomechanists use the principles of mechanics in the analysis of human movement to answer questions such as: 1. How can human performance be enhanced? 2. How can injuries be prevented? 3. How can rehabilitation from injury be expedited?

6. Areas of Biomechanics Sports Biomechanics Sports Biomechanics Occupational Biomechanics Occupational Biomechanics Clinical Biomechanics Clinical Biomechanics

7. Sports Biomechanics By understanding and applying mechanical concepts, sports biomechanists assess the most optimal way to move the body in order to achieve maximal performance, whilst minimizing risk of injury.
