UQ Brisbane Premier League Gets Put to the Test

"Sobering", hey?

Last night Gwen and Robbie (and a significant number of volunteers) put the UQ Brisbane Premier League men's squad through their paces. 


Over 2 hours, they quantified the performance of 27 players on 16 different skills tasks.

Some of the guys being tested were overheard saying things like:

Comprehensive Player Performance of UQ Squads in 2009

In 2009, the soccerscience.net crew tested several aspects of player performance in the UQ Firsts & Reserves teams. These included skill performance, athletic performance, and performance during filmed matches.

The results are in! To access the results for both teams, click HERE.

Assessment of Receiving and Passing Skill

As we discussed in the last post, a player's ability to receive and pass the ball is very important in game situations. Control can mean the difference between scoring and losing the ball to a defender. So, it's important.

We believe that a player's receiving-then-passing skills should be routinely assessed. Why? Because

The Importance of Effective Receiving and Passing

Plain and simple. Soccer players must be able to RECEIVE a ball and rapidly PASS it along using a short pass to a teammate.

Next time you watch any good football on TV - for example, the English Premier League - notice how many players on the team use the receive-then-short pass technique. Almost everyone, right? And quite often, right?

Good players make this skill look effortless - so easy in fact that you can take it for granted how difficult and how crucial it is to high-level play.

Performance Measures 2009 - UQ Firsts & Reserves

Summary
Below you'll find the results for all performance measures recorded for all UQ players that were filmed in Season 2009. Only data from players that actually completed enough on-field time during the filmed matches are provided. Players have not been identified, so if you think you may have been included in the list of players then and he'll send you your own individual player code so that you can identify your individual results.


Below the tables you'll find an explanation of the variables presented.

Results: Firsts



Results: Reserves

How to interpret the tables:

For each variable, the data have been standardised to an average of zero. This means that those that performed well in a given task scored in the positive direction while those that were below average had negative scores. It's easy to see the ranks for each player in each drill by scanning the list.

Performance Variables:
Player: Each individual player’s unique player identification code.

Overall Athleticism: This is a composite measure of an individual’s overall performance across the 16 different athletic tests measured. These included sprint speed, endurance, power, agility, and lower and upper-body power and endurance.

Overall Skill: This is a composite measure of an individual’s overall performance across all 5 skill tests, including passing accuracy, volley accuracy, heading accuracy, dribbling speed and juggling ability.

Balance: An overall measure of static balance.

Average Effectiveness: This is a measure of an individual’s average ability to successfully complete any task that they are involved in during a match. For example, this will take into consideration the overall number of passes that were successful (i.e. % success).

Season Goals: Overall number of goals scored during season 2009.

Average Match Activity: This is a measure of how often an individual is involved in activities involving the ball. This will include the number of tackles, touches, passes, shots, crosses etc. Anything that involves the ball.

Overall Match Performance: This is a measure of an individual’s average involvement and effectiveness across all tasks in a game.

Maximal Ability in any one task: This is the highest score achieved by an individual across any of the tasks measured. This can include any of the performance measures recorded, including passes, shots, goals, tackles, interception etc.

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.
See video here:  http://www.youtube.com/watch?v=XTWTsS3hvBs

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
See video here: http://www.youtube.com/watch?v=L0l5jsFukNM

Test 2: Rebound Boards at Right-angle to each other using Technique B
See video here: http://www.youtube.com/watch?v=j3k_4nkaqgo

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

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.
