Q

Construct validity

A

ability of a test to represent the underlying construct (the theory developed to organize and explain some aspects of existing knowledge and observation
overall validity or the extent to which the test actually measures what it was designed to measure
To be valid, a test should:
measure abilities important in the sport
produce repeatable results
measure the performance of one athlete at a time
appear meaningful
be of suitable difficulty
be able to differentiate between various levels of ability
permit accurate scoring
include sufficient number of trials
withstand the test of statistical evaluation

Q

Factors resulting in differences in scores

A

intrasubject (within subjects) variability
lack of interrater (between raters) reliability or agreement

15
Q

interrater reliability

A

degree to which different raters agree in their test results over time or on repeated occasions; measure of consistency
sources of interrater differences include:
variations in calibrating testing devices
preparing athletes
running the test
some athletes may be more motivated by a particular coach

16
Q

interrater variability

A
lack of consistent scores by a given tester
causes include:
leniency in hopes of seeing improvement
inadequate training
inattentiveness
lack of concentration
failure to follow standardized procedures for device calibration
athlete preparation
test administration
test scoring
17
Q

Failure of the test itself

A

more technique-intensive test generally exhibit greater variability in results and require more pretest practice to produce consistency

18
Q

test selection

A

must consider sport specificity (metabolic energy demands, biomechanical movement patterns) athlete experience, training status, age and environmental factors
the more similar the test is to an important movement in the sport, the better

19
Q

Environmental factors affecting test performance

A

temperature, humidity and altitude

20
Q

Test administration

A

accurate results require tests to be administered safely, correctly and in an organized manner
Points of emphasis:
ensure health and safety of athletes
carefully select and train testers
tests should be well organized and efficiently administered
athletes should be properly prepared and instructed

21
Q

Health and safety considerations

A

Heart problems like impaired blood flow or irregular heartbeat
heat injury
musculoskeletal injury
medical referral may be warranted for specific symptoms

22
Q

Temperature and humidity guidelines for strenuous exercise testing

A
Relative humidity 0 = temp limit 95
RH 1-20 = temp 90
RH 21-50 = temp 85 
RH 51-90 = temp 80
RH 91-100 = temp 75
23
Q

Selection and training of testers

A

test administrators should be well trained with a thorough knowledge of all testing procedures and protocols
Novices should be supervised to ensure they perform and score all tests correctly.
tester should have sufficient practice giving the tests.
They should be trained to explain and administer the tests as consistently as possible
Checklist of materials needed for testing and written test protocols to refer if there are questions

24
Q

Recording forms

A

scoring forms should be developed before the testing session with space for all results and comments
environmental conditions and specific details of the setup should be documented.

25
Q

Test format

A

athletes should be made aware of the purpose and procedures of a test beforehand.
decide if the athletes will be tested in groups or all at once and whether the same person will be administering the test to all athletes.
Preferable to have the same person administer the test is time allows.
each tester should only administer one test at a time

26
Q

Testing batteries and multiple testing trials

A

tester can administer up to 2 nonfatiguing tests in sequence
when multiple trials of a test are performed, allow complete recovery between trials
At least 2 min rest between attempts not close to max and 3 min rest for attempts close to max
Test battery using same muscle groups and measuring the same component require 5 min recover to prevent fatigue from skewing the scores

27
Q

Sequence of tests

A
nonfatiguing tests (height, weight, flexibility, skinfold and girth, vertical jump)
agility tests
max power and strength
sprint tests
local muscular endurance tests
fatiguing anaerobic capacity tests
aerobic capacity tests

design for minimal recovery time between tests
administer fatiguing anaerobic capacity and aerobic tests on different days if possible
if not possible, allow for adequate recovery time
test sessions should occur at the same time of day and preferably indoors

28
Q

Preparing athletes for testing

A

announce date, time and purpose of test battery in advance
athletes should be familiar with content and procedures
supervised pretest practice is encouraged
instructions should cover the purpose, how it is performed amount of warm–up, number of practice attempts, number of trials, test scoring, criteria for disallowing attempts, and recommendations for maximizing performance.
demonstration of proper test performance is encouraged
give athletes the change to ask questions
motivate all athletes equally
tell athletes their scores immediately
do a general and specific warm-up and a light cool down for tests that dramatically increase HR
