  1. Biomechanics of Jumping and Throwing 7/8 PE—Track and Field Unit 2nd Semester

  2. What is Biomechanics? • Biomechanics refers to the way our _______, ______, and _____ work together as we move.

  3. Description of human motion • Body is a system of _______. • A lever has a ________ (axis of rotation), an effort and effort arm, a resistance and a resistance arm. • The effort and resistance arms are usually the bones of the skeleton, and the fulcra are usually the joints of the skeleton.

  4. Center of Gravity • The _______ __ ________ is the theoretical point where all the body weight is concentrated or the theoretical point about which the body weight is evenly distributed.

  5. Force • Forces produce __________ • Force is a ______ or ________ • _________ force is created inside the athlete’s body—muscles pulling on bones • __________ forces are applied to the body—gravity, friction

  6. Horizontal Jump-Long Jump • _______ phases: Approach run, takeoff, flight, landing • _________ leads to stronger vertical take-off • Kick forward • COG is ________ on landing-knees flexed

  7. Horizontal Jump-Triple Jump • Triple jump has additional motions: • Approach • Hop (______ foot) • Step (_______ feet) • Jump (take off on ____ foot, land on ____)

  8. Vertical Jump-High Jump • ______ phases: Run-up, takeoff, flight/bar clearance • ______ approach to the bar • Push on the ground for takeoff • Twisting somersault over the bar (Bring COG as ______ as possible)

  9. Throwing-Shotput • Glide technique has a ______-______ rhythm • Knee bent (same as hand holding put) • Glide back (____ steps total) • Plant opposite foot • Turn torso (torque force) • Release at ___-____ degree angle

  10. Additional jumps and throws • ________ = combination of running and jumping (at least at lower levels) • _______ = throwing • _______ = throwing
