Transcript of Movement Analysis of Kicking A Soccer...
Introduction Kicking a soccer ball is
situational. – Depending where you are on
the field or what your objective is, the kick may be different.
– The different kicks might differ in force and distance based upon technique.
– Examples: cross, shot, and goal kicks compared to a pass in a combination play.
Mental Preparation
Players are constantly thinking “what is next” --- Head is up.
Mental preparation leads to ball set up. – Laces – Inside of foot
Ball set up leads to body preparation.
Types of Kicks
Laces Kick- Toe down, power in knee flexion. Used for crosses, corner kicks, goal kicks, and shooting.
Inside of Foot-Ankle rotated out, toes pointed up. Used for passing, and finishing (shooting).
Laces Kick Six Stages
1. The Approach
2. Foot Planting
3. Cocking of Kicking Limb
4. Swing
5. Ball Contact
6. Follow Through
Stages-Laces
Stage 1: The Approach – This stage is consecutive to the mental
preparation. Set play: Run up at an angle Shot: set up touch or Anticipation Cross: Touch to the outside of the foot kicking the
ball to create an angle.
Stages-Laces Stage Two-Foot Planting
– Determines the direction of the kick
– Done in the sagittal plane
– Result of knee extension in stride and plantar flexion. P. Flexion may proceed into dorsiflexion based upon circumstances or stage of the kick.
Stages-Laces Stage Three: Cocking of
Kicking Limb
-Power producing movement. -Knee Flexion is the main component -Plantar flexion in the kicking foot -Hip extension -Possible hip abduction.
This movement stores up force and energy that will transfer over to the swing phase.
Stages-Laces
Stage Four: The Swing – Knee extension – Hip flexion – Plantar flexion This is an explosive anaerobic movement. * Torque and moment arm play a major role in this
movement. The longer the limb and shorter moment arm, the higher the velocity will be generated.
Stages-Laces
Stage Five: Ball Contact
– Knee Extension still taking place – Continuation of hip flexion – Plantar flexion – Some dorsiflexion in planted foot
Stages-Laces
Stage Six: Follow Through – Continuation of ball contact
Knee Extension Hip Flexion Foot begins to relax -Then the reverse happens -Hip Extension bringing leg back down -Athlete lands on shooting foot
Laces-Upper Body
There is minimal movement in the upper body.
Most movement done in the frontal plane. – Lateral flexion in the torso – Arm abduction – Arm adduction

Inside of the foot The stages of using the inside of the foot are very similar. However there is more movement done in the transverse
plane. – Eversion in the foot – Lateral rotation in the knee
