Different cleats by different soccer positions

Striker
Defender
How does it work?
Target
Concrete Board
What kind of experiment is being conducted?
What is considered to measure the performance?
The levels are….
Cleats
Warm-up
Kicking Form
Foward
Defender
Warm
Cold
Inside
Outside
Uncontrollable factors that may have potential impact on the performance measure.
2^3 Full Factorial experiment with 3 replications
Which Factors play a significant role in the process?
Striker Cleats are more accurate
We found two confounded significant interactions!
Defenders Cleat
Strikers Cleat
Outside
STRETCH
Inside
Stretch by Cleat
Stretch by Form
The Reduced Model of the Process..
Accuracy= 17.31 - 5.15*Stretch + 2.73*Form - 3.29*Cleat*Stretch -5.19*Stretch*Form
What confirms the validation of the process?
Residuals are normally distributed
How someone can replicate our measures?
We see significant effects with both stretching and form
Replicate our measure:
Use a skilled soccer player
A concrete board
Measuring tape
Two other cleats
Soccer ball
What could be done to further improve the reliability of the process?
CONTROL CONTROL CONTROL!!!
Better equipment→ Reduce Variability
Use an impressionable board
Better mounting systems/ Bigger board
More accurate measuring system→ large caliper or something similar
Do specialized soccer cleats make a difference in striking accuracy?
Specialized soccer cleats are a marketing ploy for unskilled soccer players. The difference in prices is used to market toward players with few or no experience.
Striker Cleat→ $200.00
Defender Cleat→ $30.00
The physical difference for striker cleats are much lighter and defender cleats are much heavier containing more padding.
