  1. Biomechanics of Jumping

  2. Biomechanics of Jumping Applications Sports that Focus on Jumping Sports that Depend on Jumping Maximimizing Vertical Height Maximimizing Horizontal Displacement Landing

  3. Biomechanics of Jumping The Body as a Projectile Center of Gravity Follows a Parabola Acted Upon by Gravity Body May Move Around the C of G Rarely Influenced by air resistance

  4. Biomechanics of Jumping Factors Determining Path of C of G Velocity at Take-off Angle of Trajectory at Take-off Height of C of G at Take-off Aerodynamic factors

  5. Biomechanics of Jumping Maximizing Vertical Height Velocity at Take-off …….maximize, but Angle of Trajectory at Take-off………..90 degrees, but Height of C of G at Take-off…………as high as possible, but Key – Velocity compromised to optimize take-of angle Key – Adjust body position in flight to optimize relationship to C of G

  6. Biomechanics of Jumping Maximizing Horizontal Displacement Velocity at Take-off …….maximize, but Angle of Trajectory at Take-off………..90 degrees, but Height of C of G at Take-off…………as high as possible, but Key – Velocity optimized and take-of angle compromised Key – Role of the free arm and free leg

  7. Biomechanics of Jumping Aerodynamics The Extent of the Influence is a Function of the Relative Velocity Examples – Long Jumper and Headwind – Drag Ski Jump and Headwind - Lift

  8. Biomechanics of Jumping Landing Basic Objective – Change the Body’s Momentum to Zero Impulse = Force x Time As Time Increase Force Decreases Factors – Joint Motions Landing Surface Compliance Other ………
