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

Phases of Punting1. The approach and catch2. Backswing of kicking
leg& the drop3. The contact of ball and
foot4. The follow through

The Approach and Catch1.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 Through1. Carrying momentum through the
football2. Adding a hop after following
through
