Introduction
Many different types of kicks in soccer Depends on the situation you are inTwo types we are focusing on is the goal kick and a laces shot
Require slight variations in the technique for each typeSlide3
Objectives
Goal Kick: to clear the ball with maximal height and distance away from your own defensive sideLaces shot: maximum power while keeping the shot low and on targetSlide4
Flight Path
Laces Shot Goal Kick
High velocity
Follows a straight line flight path
Keep ball under 8 feet ideally
Medium velocity
Follows a parabolic flight path
As high as you can without taking away from distance Slide5
Phases
Phase 1: Deciding contact point on the ball and approaching the ball Phase 2: Cocking of the of kicking legPhase 3: Acceleration of kicking legPhase
4: Follow
throughSlide6
Approach
Laces ShotGoal kick
Sagital plane
Uses quadriceps, hamstrings and calf
Focus on contact point (near middle of ball)
Approach angle straight on (most common error)
Usually 1 or 2 step approach
Sagital plan
Uses quadriceps, hamstrings and calf
Focus on contact point (near bottom of ball)
Approach angle towards 45 degrees of ball
Usually 5 or 6 yard approachSlide7
Cocking of leg
Laces ShotGoal Kick
Try to create longest moment arm as possible
Extension of hip, flexion of knee, plantar flexion of ankle all in
sagital
plane
Plant foot even with ball, knee and chest over the ball
Horizontal adduction of opposite shoulder
Try to create longest moment arm as possible
Extension of hip, flexion of knee, plantar flexion of ankle all in
sagital
plane
Plant foot even with ball, knee slightly behind the ball, upper body leaning back
Both shoulders
hyperextendedSlide8
Leg Acceleration
Laces shotGoal Kick
Flexion of hip, extension of knee, plantar flexion of ankle in
sagital
plane
Extend knee as fast as possible to create greater velocity
Upper body leaned forward
Contact ball with laces
Flexion of hip, extension of knee,
eversion
of ankle in
sagital
plane
Extend knee as fast as possible to create greater velocity
Upper body leaned back
Contact ball with instepSlide9
Follow Through
Laces ShotGoal Kick
Extension of knee, hip flexed, plantar flexion in ankle
Upper body leaned further forward
Jump off plant foot, land on kicking foot
Kicking foot follows through in a straight line
Extension of knee, hip flexed,
dorsiflexion
of ankle
Upper body leaned further back
Plant foot stays on the ground, land on kicking foot
Kicking foot follows through in a curved pathSlide10
Laces ShotSlide11
Goal KickSlide12
Leg Velocities

Goal Kick
Angular Velocity 10.2

Ball Velocities and Forces
Laces Shot53 mph
Goal Kick
47 mphSlide14
Velocities of Laces Shot
The average professional shot is 30 meters per second (67 MPH)Average youth shot (12-17 years old) is around 15 meters per second (32 MPH), Average college and high level amateur adults shot around 25 meters per second (55 MPH)Slide15
