Testing Player Skill in Coventry City Football Academy

In January, Robbie (and his collaborator, Rob James) spent 10 days in Coventry, UK, testing young players at the Coventry City Football Academy




And now the results are in! Coventry coaches and players for the Academy's U18s and U16s teams can access their results here.

(NOTE: results are presented without identifying individual players, but coaches have been given this information)

Testing Player Skill in Coventry City Football Academy

Recently, Robbie was in Coventry (UK) for a week working with Dr. Rob James from Coventry University. Robbie and Rob have been long-time collaborators in the area of performance ... and this time their work took them to the Coventry City Football Academy.


They tested several

Coventry City Football Academy - Dribbling & Rebound Board Performance

Summary
Dribbling: For dribbling, three different tests were performed by each player. The results quoted in the table are the average time it took a player to perform each of the different tests (each test was performed three times). Each test required the players to dribble the ball through a circuit in the fastest possible time. Penalties were applied for players missing any cones during the circuit or touching the ball with the incorrect foot (when appropriate).

Test 1: Time taken to dribble the ball through the circuit using the left foot only.

Test 2: Time taken to dribble the ball through the circuit using the right foot only.

Test 3: Time taken to dribble the ball through the circuit using either foot

Rebound Board Performance: Four different tests were performed by each player. The results quoted in the table are the average time it took a player to perform each of the tasks (each task performed twice). Each task included ten circuits of the rebound boards (20 passes and 20 controls), with a penalty of 1 second added to a player’s time for each mistake made during the task (i.e. missing the rebound board, kicking with the wrong foot or for every extra touch of the football).

Test 1: Rebound Boards at Right-angle to each other using Technique A

Test 2: Rebound Boards at Right-angle to each other using Technique B

Test 3: Rebound Boards at a 135 degree angle to each other using Technique A

Test 4: Rebound Boards at a 135 degree angle to each other using Technique B

The results

How to interpret the table:

Player: Each individual player’s unique identification

Dribbling Both Feet (s): Average Time taken to dribble the ball through the circuit using either foot .

Dribbling with Left Foot (s): Average time taken for each player to dribble the ball through the circuit using the left foot only.

Dribbling with Right Foot (s): Average time taken to dribble the ball through the circuit using the right foot only.

Dribbling Asymmetry: The difference in average points between the different feet. The closer to 0 then the smaller the difference is between the left and right feet. A larger number shows that the player is much better at dribbling with one foot compared with the other.

Rebound Board Right-angle (s): Average time taken by a player to complete the test using Techniques A & B (including time penalties for mistakes)

Rebound Board Wide-angle (s): Average time taken by a player to complete the test using Techniques A & B (including time penalties for mistakes)

Coventry City Football Academy - Juggling Performance

Summary
Juggling Performance Tests: Each player was given 60 s to complete as many juggles as possible using only the correct technique. The first test required players to kick the ball alternating between the right and left foot. The second test required the players to use their left foot only whilst keep the right foot fixed and unmoved, while the third test was using the right foot only. Each test was repeated for each player so that it was performed on two occasions - results represent the average of the two tests.

How to interpret the table:

Player: Each individual player’s unique identification

Alternate Juggle Average: Average number of juggles completed by each player using the correct technique of kicking with alternate feet during 60 seconds.

Juggle Left Foot: Average number of juggles completed by each player using their left foot only (the right foot was unmoved and fixed to the ground) during 60 seconds.

Juggle Right Foot: Average number of juggles completed by each player using their right foot only (the left foot was unmoved and fixed to the ground) during 60 seconds.

Asymmetry Juggling: The difference in # of juggles completed between the different feet. The closer to 0 then the smaller the difference is between the left and right feet. A larger number shows that juggling skills are much weaker with one foot than the other.

Coventry City Football Academy - Passing & Shooting Accuracy

Summary
Passing Accuracy over 20 m: Each player made approximately 14 passes with their right foot and 14 passes with their left foot at the scoring target. The maximum number of points that could be scored in any single kick was 10 points. Thus, the closer each player’s score was to 10, the better their kicking accuracy. For each point below 10 pts, a player was missing the target by approximately 0.25m.

See video here of test: http://www.youtube.com/watch?v=amaCZ9E7pxA

Lofted Passing Accuracy over 35 m: Each player made approximately 10-14 passes with their right foot and 10-14 passes with their left foot at the scoring target. The maximum number of points that could be scored in any single kick was 20 points.

See video here of test: http://www.youtube.com/watch?v=kpvBGyaw7BY

Shooting Accuracy over 20 m: Each player made approximately 14 shots with their right foot and 14 shots with their left foot at the scoring target (identical to 20m passing accuracy target).

Wall Pass Performance: Each player was given 45 s to complete as many wall-passes as possible, whilst alternating between left and right footed passes. The maximum number of points that could be scored with each pass was 6 points, and the time limited the number of wall passes that could be attempted during each trial. A player was allowed three attempts at this performance test and the average across the three was used to determine the overall wall pass performance.

The results


How to interpret the table

Player: Each player’s unique identification

20 m Passing Accuracy (Pts): The average points scored by each player for all kicks (both left and right foot kicks) - max 10 points for each kick

20 m Passing Asymmetry (Pts): The difference in average points between the different feet. The closer to 0 then the smaller the difference is between the left and right feet. A greater difference means the player is much more accurate with one foot than the other.

35 m Lofted Passing Accuracy (Pts): The average points scored by each player for all kicks (both left and right foot kicks) - max 20 points for each kick

35 m Lofted Passing Asymmetry (Pts): The difference in average points between the different feet. The closer to 0 then the smaller the difference is between the left and right feet. A greater difference means the player is much more accurate with one foot than the other.

20 m Shooting Accuracy (Pts): The average points scored by each player for all kicks (both left and right foot kicks) - max of 10 points for each kick

20 m Shooting Accuracy Asymmetry (Pts): The difference in average points between the different feet. The closer to 0 then the smaller the difference is between the left and right feet. A greater difference means the player is much more accurate with one foot than the other.

Wall-Pass (Pts): The average score achieved by an individual across all three trials.
