  1. WELCOME TOKIN 241A: BiomechanicsCourse Instructor: Professor Bob Vigarsweb site http://instruct.uwo.ca/kinesiology/241a Student obligations in class out of courtesy & respect for all: 1. During class, only talk when requested by instructor2. Put away any newspapers and be attentive to class 3. Turn off cell phone and internet connection 4. No food or drink in classroom 5. Place any refuse in appropriate bins in classroom

  5. OPO:Project forAccuracy

  6. OPO:Accuracywith Speed

  7. OPO: Manipulate a Resistance

  8. OPO: Move Over a Timed Distance

  9. Move Body in an Ideal or Model Pattern

  10. OPO: Interact with the Environment

  11. DEFINITIONS • Biomechanics- mechanics of structure & function • Mechanics - statics & dynamics • Statics - nonmoving systems • Dynamics - kinetics & kinematics • Kinetics - forces that cause movement • Kinematics - describing motion

  12. buoyancy centripetal elasticity fluid drag fluid lift friction gravity muscle pressure reaction Kinetics - forces

  13. Kinematics- describe movement • velocity - m/sec., degrees or rads/sec. (57.3°) • acceleration - change v OR change direction • displacement - in meters or degrees / radians • momentum - M = mv (linear) OR L = I (rotary)

  14. Efficient Movement • minimal energy expenditure • necessary for endurance sports and repetitive tasks in labor • allows performer to endure longer • allows performer to performer faster with less energy expended

  15. Effective Movement • not concerned with efficiency • most appropriate movements to achieve Mechanical Purpose [MP] aka Overall Performance Objective [OPO] • most appropriate sequence of movements [e.g. large parts then small parts]

  16. Assignment for Next Class • Read Chapter 1 pages 1-6 • Answer Questions # 1,3,5,6 on page 6 • Read Module A pages 7-22 • Answer Questions # 1,3,4,5,6 on page 22 http://instruct.uwo.ca/kinesiology/241a
