NSCA CSCS Chapter 12 & 13 Testing

what is the degree to which test measures what it is suppose to measure

validity

extent to which the test actually measures what it is was designed to measure

construct validity

does the test look like it measures what it suppose to measure

face validity

assessment by experts to make sure the test covers all relevant subtopics or abilities associated w/ test

content validity

the extent to which test scores are associated w/ some other measure of the same ability

criterion referenced validity

extent in which test scores are associated with another test score measuring the same ability

concurrent validity

high positive correlation between 2 test that SHOULD be related

convergent validity

extent to which test score is associated with future behavior or performance

predictive validity

test whether concepts that are unrelated are actually unrelated

discriminant validity

what is a measure of the degree of consistency or repeatability of a test

reliability

assessment of local muscular endurance, test should be separated by at least 5 minutes to prevent fatigue

test battery

aerobic performance for a test can be impaired at what temperature and humidity?

temperature 80 degree and humidity 50%

Test sequencing should happen how?

1. non fatiguing components (height and weight)

2. agility ( t-test)

3. max power and strength (1RM)

4. sprint test (40m)

5. local muscular endurance (pushups)

6. fatiguing anaerobic test (300m run)

7. aerobic capacity test (1.5 mile run)

What are a few examples of agility test?

pro-agility, and t test

What is a common movement done to screen movements?

overhead squat, this allows for the bilateral movement of hips, knees, & ankles along w/ shoulder & thoracic spine to be looked at

difference between athletes score at beginning and ending of training period or between any 2 separate training periods

difference score

allows one to draw conclusions about a population from info collected in population sample

- ex: a 9th grade gym class of boys is put thru battery test & results are apply to all 9th grade boys in school. This is an example of drawing a conclusions from population sample & applying to an entire population

inferential statistics

a more useful approach for practitioners because it allows interpretation of the clinical significance of fitness testing

- smallest worthwhile change and effect size are important in calculating the magnitude of change in a fitness test

magnitude statistic

is a measure of the variability of a set in scores about the mean

standard deviation

what are the two common measures of variability?

1. range

2. standard deviation
