Week 9 - Field Testing + Agility Flashcards
Define fitness
Overall physical cond of the body
List the reasons to measure fitness
ID strengths + weaknesses
Provide baseline measures
Develop athlete profiles
Evaluate effectiveness of training
Provide FB
Monitor rehab
Motivate players
Talent ID
How is fitness measured?
Lab based data collection
Field based data collection
What makes a good test?
Validity
Reliability
Objectivity
+ives to lab based data collection
High levels of internal validity
More control over all variables
Only measuring aspect you want to be measured
-ives to lab based data collection
Low levels of ecological validity
Expensive equipment
What is ecological validity
Being as close to reality as possible
+ive to field based data collection
Mimics perf env so can claim ecological validity
Cheaper than lab based
More accessible
-ive to field based data collection
Can’t control all variables = difficult to claim internal validity
Define content validity
Refers to the extent to which an assessment represents all facets of task w/in the domain being assessed.
Define criterion-related validity
Extent to which the output of the test correlates to the criterion measure.
Define concurrent validity
Refers to another criterion-related validity.
Determined by relating test scores of a group of subjects to a criterion measure administered at the same time as or shortly after the test.
Define reliability
Refers to if you carried out the research again, would you get the same or similar results.
Define test-retest reliability
1 researcher conducting same test on same ind. on a no. of occasions, getting same or similar results.
ICCs (Intraclass correlation coefficient)
Define inter-rater reliability
Multiple researchers conducting same test on same ind on a no. of occasions.
How is observed score calculated?
True score + error score
What is the true score?
Portion reflecting task perf
What is the error score?
Portion due to factors other than true ability
i.e wind speed
What can the performer do to improve validity + reliability of tests carried out?
No training on day of testing
Test at same time of day on each consecutive testing occasions to red inevitable biological variance
Familiarisation
No smoking or alcohol on day of test, even 2 days before.
Avoid excess amounts of tea + coffee (no more than 2 cups)
Ensure perf wears similar footwear + clothing on each occasion.
What can the administration do to improve validity + reliability of tests carried out?
Under same env cond
Same social conditions
Same test protocol
Make warm up test specific
Correct technique
Practise test trials
Test completion i.e stopping perf when they’ve missed 2 consecutive shuttles on the 20m shuttle run test.
What are the recommended env cond in which to carry out a test?
18-22 degrees
Rel humidity less than 60%
What can be done to improve validity + reliability of tests carried out in relation to intrumentation?
Ensure familiarity w/ set up of test equip
Carefully calibrate any test instrumentation
Ensure spare batteries, membranes for ultrasound devices…
What can be done to improve validity + reliability of tests carried out in relation to test delivery?
Make sure you know exactly how to measure or score each test
Dont score generously due to wanting perf to perform well
Report scores to the precision of whole testing procedure
What are the main ways to look at testing errors?
Coefficient of variance (CV)
Confidence level
Objectivity
TESTING ERRORS
Coefficient of variance
Observed score doesn’t necessarily equal a true score which occurs w/in a range dependent on the reliability of that test.
TESTING ERRORS
Confidence level
Used in conjunction w. CV
Predicts chances of making an incorrect interpretation about test score.
What are the tests to measure agility?
Illinois
505 Test
T test
Zig-Zag tests
Reactive Agility test
RAS test
How is agility improved?
Strength training lowered time to complete football specific test.
Circuit training improves agility + anaerobic endurance.
Plyometric training - 8 weeks
Agility training
ICCs (Intraclass correlation coefficient) values to categories
- > 0.75-Excellent
- 0.75-0.4 - Fair-good
- <0.4 - Poor
