The full motion of Punting
Muscle Action During Punting
Iliopsoas-flexes the hip
Rectus Femoris-flexes the hip
Sartorius-flexes the hip
Kicking knee
Hamstring-flexes the knee
Quad- extends the knee
Kicking ankle- Plantar flexed-gastrocnemius-soleus-flexor digitorum longus-flexor hallucis longus-tibialis posterior- peroneus longus-peroneus brevis
Standing ankle- Plantar flexors as above
Dorsi flexors-tibialis anterior-extensor hallucis longus-extensor digitorum longus
Common Injuries Associated with Punting
Quad injuries are the most common
Quad is most likely to tear when the punting let makes contact with the ball
The ball transmits a retarding torque though the leg to the quad, tearing it
Potential of injury can be changed by manipulating the mechanics of the ball
Like decreasing the pressure of inflation.
