Movement Skill Analysis of Punting
By
Cody Hawk & Jacob Gieselman
12/6/13Slide2
Skill Objective
To explain the biomechanical principles of a punt such as coefficient of restitution, angular velocity, and projectile motion.Slide3
Special Considerations of Punting
Atmospheric Conditions
Barometric Pressure
Wind Speed
Ball Size (coefficient of restitution)Slide4
Phases of Punting
The approach and catch
Backswing of kicking leg& the drop
The contact of ball and foot
The follow throughSlide5
The Approach and Catch
Distance
Stance
Catching the ball
Holding the ballSlide6
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 footSlide7
Contact of Ball and Foot
Head up and over support foot
Ball flat against foot
Kicking foot should demonstrate dorsiflexionSlide8
Follow Through
Carrying momentum through the football
Adding a hop after following through Slide9
