Movement Analysis of Kicking A Soccer Ball Kendra Alberts - Kyleah Bowder - Kelsey Timmerman

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

Main Muscles

  Quadriceps   Hamstrings   Gluteus Max and Min   Periformis   Abdominals   Psoas   Gastrocnemius   Adductors of the leg
