Movement Skill Analysis of Punting

By

Cody Hawk & Jacob Gieselman

12/6/13

Skill Objective

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

Special Considerations of Punting

Atmospheric Conditions

Barometric Pressure

Wind Speed

Ball Size (coefficient of restitution)

Phases of Punting

1. The approach and catch2. Backswing of kicking

leg& the drop3. The contact of ball and

foot4. The follow through

The Approach and Catch

1.Distance2.Stance3.Catching the ball4.Holding the ball

Backswing of Kicking Leg & The Drop

1. Two steps2. Planting the non-kicking foot3. Flexing his kicking leg

(Potential energy)4. Correct arm motion 5. Drop the ball in front of planted foot

Contact of Ball and Foot

1.Head up and over support foot2.Ball flat against foot3.Kicking foot should

demonstrate dorsiflexion

Follow Through

1. Carrying momentum through the football

2. Adding a hop after following through
