Movement Skill Analysis of Punting
ByCody Hawk & Jacob Gieselman
12/6/13
Skill ObjectiveTo 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 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

Summary• 4 phases of a punt• Potential into kinetic energy• Types of punting• Projectile motion and flight
time
Equation: Vertical and Horizontal component
of Parabola
V(x) = V cos Ө V(y) = V sin Ө
