Practical/Applied Flashcards
(434 cards)
Test
a procedure for assessing ability in a particular endeavor
Field test
a test used to assess ability that is performed away from the laboratory and does not require extensive training or expensive equipment
Evaluation
the process of analyzing test results for the purpose of making decisions
Pretest
a test administered before the beginning of training to determine the athlete’s initial basic ability levels
Midtest
a test administered one or more times during the training period to assess progress and modify the program as needed to maximize benefit
Formative evaluation
periodic reevaluation based on midtests administered during the training, usually at regular intervals
Posttest
a test administered after the training period to determine the success of the training program in achieving the training objectives
Validity
The degree to which a test or test item measures what it is supposed to measure
The most important characteristic of testing
Construct Validity
the extent that a test measures what it is designed to
how well does a test actually measure what it is supposed to measure?
Face validity
the appearance to the athlete and other casual observers that the test measures what it is purported to measure
Content validity
the assessment by experts that the testing covers all relevant subtopics or component abilities in appropriate proportions
Criterion-referenced validity
extent to which test scores are associated with another measurement of the SAME ABILITY.
How is a good score on the Army push-up test associated with the ACSM push-up test? Both these tests measure the same ability (chest muscle endurance).
Concurrent validity
extent to which test scores are associated with those of other accepted tests.
Ex: having a strong 1RM for the dumbbell bench press would have a strong association with the 1RM barbell bench press.
Convergent Validity
is evidenced by high positive correlation between results of the test being assessed and those of the recognized measure of the construct (the “gold standard”)
Ex: the results of the 1RM dumbbell bench press have a high correlation to the results of the 1RM bench press, and they measure the same construct (pectoralis major strength)
Predictive Validity
the extent to which the test score corresponds with future behavior or performance
Ex: having a stronger 1RM bench press will result in more sacks during the season
Discriminant validity
ability of a test to distinguish between two different constructs, resulting in a low correlation between the results of the two tests.
Ex: comparing vertical jump to 1RM bench press. These tests assess skills and abilities that are unrelated to one another
Reliability
A measure of the degree of consistency or repeatability of a test
Intrasubject variability
The lack of consistent performance by the person tested
Interrater reliability
The degree to which different raters agree; also referred to as objectivity or interrater agreement
Intrarater variability
The lack of consistent scores by a given tester
Test Selection
Metabolic Energy System Specificity
• Consider energy demands (phosphagen, glycolytic, and oxidative) of the sport when choosing or designing tests.
Biomechanical Movement Pattern Specificity
• The more similar the test is to a movement in the sport, the better.
Experience and Training Status
• Consider the athlete’s ability to perform the technique.
• Consider the athlete’s level of strength and endurance training
Age and Sex
• Both may an affect athlete’s experience, interest, and ability.
Environmental Factors
• High temperature and high humidity can impair performance, pose health risks, and lower the validity of aerobic endurance tests
• Temperature fluctuations can reduce ability to compare test results over time
• Altitude can impair performance on aerobic endurance tests
Aerobic Endurance Testing in the Heat
During the weeks prior to the test, athletes should engage in enough training to establish a baseline of fitness in the activity being tested
Avoid testing under extreme combinations of heat and humidity
On days when the temperature is high, indoor facilities should be used, or testing should be conducted during morning or early evening hours
The athletes should be acclimatized to the heat and humidity for at least one week prior to testing
Athletes should make sure they are well hydrated in the 24-hour period preceding aerobic endurance testing in the heat
Athletes should be encouraged to drink during exercise in the heat, ideally 150 to 250 ml (5-9 fluid ounces) every 15 minutes
Athletes should wear a light-colored, loose-fitting tank top and shorts, preferably of a mesh material
Be attentive to possible symptoms of heatstroke or heat exhaustion: cramps, nausea, dizziness, difficulty in walking or standing, faintness, garbled speech, lack of sweat, red or ashen skin, and goose bumps
Be aware of the symptoms of hyponatremia or water intoxication: extremely dilute urine in combination with bloated skin, altered consciousness, or loss of consciousness, with no increase in body temperature.
Athletes should be encouraged to eat foods high in magnesium and potassium.
Proficient medical coverage should be readily available
Selection and Training of Testers
Provide testers with practice and training. Ensure consistency among testers
Test Format
Consider whether athletes will be tested all at once or in groups
Multiple testers allowed but they should give the test to the same athletes each time
Each tester should administer one test at a time
