2.  Many different types of kicks in soccer  Depends on the situation you are in  Two types we are focusing on is the goal kick and a laces shot  Require slight variations in the technique for each type

3.  Goal Kick : to clear the ball with maximal height and distance away from your own defensive side  Laces shot: maximum power while keeping the shot low and on target

4. LACES SHOTGOAL 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

5.  Phase 1: Deciding contact point on the ball and approaching the ball  Phase 2: Cocking of the of kicking leg  Phase 3: Acceleration of kicking leg  Phase 4: Follow through

6. 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 approach

7. 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 hyperextended

8. 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 instep

9. 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 path

12.  Laces Shot  Angular velocity: 12.2 Rad/s  Tangential velocity: 20.62 m/s  Goal Kick  Angular Velocity 10.2 Rad/s  Tangential velocity 17.2 m/s

13.  Laces Shot  53 mph  Goal Kick  47 mph

14.  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)
