  2. MOVEMENT ANALYSIS CAN BE APPLIED TO: Athletics Industry Medicine Space

  3. ALL APPLICATIONS UTILIZED SIMILAR QUANTIFICATION TECHNIQUES

  4. Basic Components of Motion Analysis System force plate EMG video cameras external monitor notebook computer portable printer portable VCR optional A/D devices

  5. The Early 70's use of high speed cinematography

  6. NEW TECHNOLOGIES For Your Professional Toolbox Computerized Video ) Analysis [Kinematics] Force Plate [Kinetic ) Ground Reaction] 3D Dynamic EMG ) Internet Interface )

  7. Athletic performances can Athletic performances can be divided into a wide be divided into a wide spectrum of activities. spectrum of activities.

  8. The Spectrum of Athletic Performances • Explosive Events • Throwing • Sprinting • Jumping • Endurance Events • Long Distance Run • Swimming • Cycling • Accuracy Events • Golf • Archery • Team Sports • Soccer • Basketball • Hockey • Esthetic Events • Figure Skating • Gymnastics • Diving • Multi Events • Decathlon • Pentathlon

  9. Analysis of Performance Require: • Video Recording • Digitizing the Data • Manual • Automatic • Transformation of the Data • 2D - Two Dimensional • 3D - Three Dimensional

  10. High Speed Camera at 240 Hz
