Presentation Transcript

  1. BiomechanicsPhysics of Physical Activity

  2. Quantitative Analyses • Involves more precise measurement of variables that are thought to optimize or maximize the behavior of interest Such analysis allow us to describe motion in terms of: • #1 Kinematics • #2 Kinetics

  3. Evaluation of Kinetics describing the underlying cause of motion: • #1 Pressure and Force Transducers • #2 Force Plates or Platforms • #3 Isokinetic Dynamometer

  4. Force: F = ma is any action, a push or pull, which tends to cause an object to change its state of motion by experiencing an acceleration

  5. Using kineticsForces underlying Physical Activity

  6. Ground Reaction Force: Gait Analysis Ground reaction force(GRF) is the force exerted by the ground on a body in contact with it derived from Newton’s third law

  7. GRF: Shod and Barefoot
