  1. Movement Skill Analysis of Punting By Cody Hawk & Jacob Gieselman 12/6/13

  2. Skill Objective To explain the biomechanical principles of a punt such as coefficient of restitution, angular velocity, and projectile motion.

  3. Special Considerations of Punting Atmospheric Conditions Barometric Pressure Wind Speed Ball Size (coefficient of restitution)

  4. Phases of Punting The approach and catch Backswing of kicking leg& the drop The contact of ball and foot The follow through

  5. The Approach and Catch Distance Stance Catching the ball Holding the ball

  6. Backswing of Kicking Leg & The Drop Two steps Planting the non-kicking foot Flexing his kicking leg (Potential energy) 4. Correct arm motion 5. Drop the ball in front of planted foot

  7. Contact of Ball and Foot Head up and over support foot Ball flat against foot Kicking foot should demonstrate dorsiflexion

  8. Follow Through Carrying momentum through the football Adding a hop after following through

  9. Videos • Slow motion punt http://www.youtube.com/watch?v=tCUxB_8CeTo • http://www.youtube.com/watch?v=6yJIz8-Odz0

  10. Summary • 4 phases of a punt • Potential into kinetic energy • Types of punting • Projectile motion and flight time

  11. Equation: Vertical and Horizontal component of Parabola • V(x) = V cosӨ • V(y) = V sin Ө
