Biomechanics: Soccer Kick
Performance Errors:
Mechanical Analysis:
Plant Phase:
- Begins when non-kicking leg has forward motion
- Hip - extends
- Knee - begins to flex
- Ankle - beings to plantar flex
- Ends when non-kicking foot makes contact with the ground
- Plant foot placement
- Perpendicular to ball
- Pointed towards target
- Follow through swing
- Knee - extended
- Foot - plantar flexed
- Angle of approach
- 30 to 45 degrees
- Allows more pelvic rotation
Soccer Kick
Kick Phase:
Back Swing Phase:
- Begins with forward motion of the thigh
- Hip - flexes
- Knee - extends
- Ankle - plantar flexes
- Ends when impact is made with the ball
- Begins when kicking leg moves backwards
- Hip - extends / external rotation
- Knee - flexes
- Ankle - plantar flexes
- Ends when hip is in maximum extension
- Factors
- Balance - center of gravity
- Strength - contraction speed
- Flexibility
- Neuromuscular adaptation
- Principles
- Ball moves in direction of force
- Ball / Athlete velocity
- Momentum transferred in collision
- Longer the follow through the greater the change in momentum
- Greater mass the greater momentum
- The higher the elasticity of the ball, the higher the velocity
- Ballistic / Sequential motion that has high velocities and braking forces, risk of injury
- Kicking a soccer ball is a sequential movement in which the aim is to project the ball a given distance at an accurate point.
Follow Through Phase:
- Begins after foot is in final contact with the ball
- Hip - flexes
- Knee - flexes
- Ankle - plantar flexes
- Ends when hip extends to bring kicking leg back down
