Presentation Transcript

  1. APPLIED BIOMECHANICS KIN 340

  2. Introduction What is Biomechanics? The study of internal and external forces acting on the body segments, and the effects produced by these forces. The principles of engineering, specifically mechanics, applied to human movement.

  3. Mechanics Statics constant state of motion Dynamics acceleration present Kinetics of motionless systems Constant velocity systems Kinematics Kinetics Kinematics Kinetics

  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 • Occupational 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.

  8. Sequential motion: the acceleration of body segments occurs sequentially, in a proximal to distal fashion Ideal coordination pattern for most throwing and striking skills.

  9. Occupational Biomechanics The goal is to design machines and the workplace to reduce repetitive stress on workers’ joints.

  10. Clinical Biomechanics Clinical biomechanists analyze the mechanics of injured patients and provide feedback (biofeedback) to restore normal function.
