What is test validity?
Validity is the degree that a test or item in a test measures what it is supposed to measure. This is possibly the most important characteristic of tests.
Name the different types of validity
Construct
Face
Content
Criterion
Name the different types of Criterion Referenced validity
Concurrent
Convergent
Predictive
Discriminant
Describe Construct Validity
Construct Validity is the ability of a test to represent the underlying construct. The other validity types are secondary to construct validity and they essentially provide evidence for the construct validity.
Describe Face Validity
Face Validity is the appearance that the test is measuring what it is supposed to measure. This is mostly for the athlete doing the test or the casual observers on the side.
Describe Content Validity
Content Validity is an assessment by some experts covering all of the relevant subtopics or the component abilities in the appropriate portions. Some component abilities could be jumping ability, sprinting, or strength in the lower body, to name a few examples.
Define Criterion Referenced Validity
Criterion Referenced Validity is the extent that test scores are associated with another measure of the same thing. There are four types of this validity:
- Concurrent
- Convergent
- Predictive
- Discriminant
Define Concurrent Validity
Concurrent Validity refers to how much the test scores have to do with accepted tests of the same ability.
Define Convergent Validity
Convergent Validity refers to the high positive correlation between test results that are being assessed and the others that are recognized as the gold standard.
Define Predictive Validity
Predictive Validity refers to how a test score corresponds with future performances or behaviors. Possibly the comparison of the score and a measure of success within the sport.
Define Descriminant Validity
Discriminant Validity refers to the ability of a test to find differences between two different constructs and is shown by low correlation between test results and tests of different constructs.
What factors do we need to consider when selecting a test (5 Things)
o The Metabolic Energy System Specificity: This looks at what their sport demands in terms of energy systems (phosphagen, glycolytic, and oxidative). We want the test to be somewhat similar to the
sport, so that it stays relevant.
o Biomechanical Movement Pattern Specificity: The more similar a test is to the important movements within the sport, the better it is.
o Experience and Training Status: We have to consider the ability of the athlete to perform the test, along with their current level of strength and endurance.
o Age and Sex: Both of these affect the experience, interest, and ability in doing the test chosen.
o Environmental Factors: Some aspects of the weather can affect the tests we choose. High temp and high humidity condition can affect athletic performance and lower the validity of our tests. It can also reduce results over time. Altitude is another big possible reducer in performance and validity.
What precautions must we take in the heat with athletes aerobic testing and why?
5 Things
It is important that first, athletes should have
training enough to have a baseline of fitness in the activity we are looking to test.
Testing under extreme heat and humidity together can be very dangerous and should be avoided. If possible, we should use indoor facilities, or at least shoot for the end or beginning of the day.
If they must work out in the hot humid part of the day, make sure they are well hydrated and stay well hydrated. During activity, athletes should take in 150 – 250 mL of fluid every 15 minutes.
Light colors and loose fit clothes are preferable.
We should also make sure to look out for signs of exhaustion.
Explain the testing order
Our typical testing order begins with our 1) non-fatiguing tests like stretching.
We next go to 2) agility tests, 3) max power and strength, and 4) sprint tests, in that order.
These require max power in short burst and are overall less fatiguing than aerobic capacity tests. We then do our 5) local muscular endurance tests.
Followed by our more fatiguing 6) anaerobic capacity tests.
The final type of tests we end testing with, are the 7) aerobic capacity tests, which are the most exhausting typically.
What is the most common test for maximum strength or power?
The one rep max test (1RM) is used for measuring maximum muscular strength and sometimes for maximum muscular power. This test is useful for
athletes, because of the use of the percentages of 1RM can be effective in determining rep ranges for the future.
What is the 1RM protocol (general info)
When administering the 1RM test, we start by warming with sets of the exercise at Submax loads beginning light.
Usually the first attempt is about 50% of the estimated 1RM. Rest of 1 – 5 minutes is preferable, as long as the client feels well rested.
The weight is increased depending on the difficulty of the last attempt.
The 1RM will typically be found in 3 – 5 sets.
Define Agility
This is the ability for us to stop, start, and change the direction of the body or body parts quickly, but with control.
Define Speed
This refers to the movement distance per some unit of time. Typically, we quantify it as the time taken to cover a fixed distance.
Define Flexibility
ROM for joints in the body
Define Anthropometry
This is the science of measurement applied to the human body. Typically, the measurements are of someone’s height, weight, and selected body girths.
Define Body Comp
This is the relative proportions of weight and lean
tissue.
What are the procedures for the two jump tests that test Maximum Muscular power? How do they differ and what is required?
There are two typical tests for testing vertical jump height. We use the Vertical Jump Test and the Standing Vertical Jump Test.
The typical items needed for the vertical jump test are a wall and chalk for one procedure, or a commercial Vertec device.
For the standing vertical jump test, we use a contact mat, and the only other difference is that you hold the
squat at the bottom so that the countermovement is removed from the jump. This bottom position is held for 2 – 3 seconds prior to jumping.
What are the four aerobic capacity tests mapped out in the book?
There are 4 aerobic capacity tests. The 1.5 mile run, the 12 minute run, the yo-yo intermittent recovery test, and the maximal aerobic speed test.
Describe the test and the protocol for the Yo-Yo intermittent recovery test (7 Steps)
This test is more ideal for team sports due to them mimicking short intensive bursts of exercise and then immediate short recovery periods.
Both tests consist of a 2 by 20 meter shuttle run with speeds increasing and 10 seconds of recovery. The IRT1 starts at 10 kilometers per hour, and IRT2 starts at 13 kilometers per hour.
Strength and conditioning professionals should use the IRT1. The procedure is as follows:
- Mark out 20 meters and arrange the cones. Markers are 2 meters apart at both the start and the end. Measure a distance that is 5 meters behind the start.
- Warm up and stretch prior to testing.
- Testing starts with the athletes at the starting line.
- When given a sound, they run to the turn line. When the second sound starts, athletes arrive at the turn line and run back to the start in time for the sound.
- When passing the start, athletes run to the marked 5 meter distance and then return to the start.
- The athletes go as long as they can without missing the sounds. One missed sound results in a warning, two misses results in failure.
- The end result for how long they lasted is recorded.
