Chapter 12 Flashcards
First class lever
Muscle force and resistance act on opposite sides of the fulcrum. Ex: triceps or AO joint.
Second class lever:
Muscle fire and resistance are on the same side of the fulcrum. However the moment arm for the muscular force is longer and thus advantaged. Ex: gastroc at ankle
Third class lever:
Muscle force and resistance are are on the same side of the fulcrum. However, resistance is acting on a longer moment arm and is this advantaged. Ex: biceps at the elbow
Scheduling priority
In season teams have priority over off season teams.
Components of an emergency action plan
- Ems activation procedures
- names & telephone numbers for primary, secondary, contacts.
-facility address
-locations of telephones
-locations nearest exit
-designated staff to care for injuries
-ambulance access points
-location of emergency supplies/first aid
-plan of action in case of fire, tornado, etc..
Prior to an athlete using equipment, they must obtain what?
A pre-participation, physical evaluation
How frequently should cables and belts and resistance training machines be inspected?
Daily
Validity
Does a test measure what it is supposed to?
Construct validity
Ability of test to represent underlying construct.
Face validity
Appearance to athlete that test measures what it is supposed to.
Content validity
Assessment by experts that testing covers all subtopics relevant to a particular sport.
Concurrent validity
Extent to which test scores agree with other tests measuring same ability
Convergent validity
Correlation between test results and those of gold standard
Predictive validity
Extent to which test score predicts future performance
Discriminative validity
Ability of test to distinguish between two different constructs
Reliability
Degree of consistency or repeatability of a test. A test must be reliable to be valid, but not vice versa
Intrasubject variability cause
Lack of consistent performance by the person being tested.
Intrarater variability
Lack of consistent scores by a given tester.
Factors to consider when selecting tests
-metabolic energy system specificity
-biomechanics movement pattern specificity
-experience and training status
-age and sex
-environmental factors (heat/humidity)
Temp/humidity for exercise testing
-0% 95 deg
-1-20% 90 deg
-21-50% 85 deg
-51-90% 80 deg
-91-100% 75 deg
How many non fatiguing tests can be administered in sequence by single tester
2 such as a vertical jump immediately followed by a static jump
Rest between sets not close to 1RM when testing for 1RM
2 minutes
Rest between sets close to 1RM when testing for 1RM
3 minutes
Test battery
Such as max push up followed by max pull up tests. Should be 5 min between
How long should athlete be acclimatized to heat prior to testing in heat?
1 week
Signs of hyponatremia
-dilute urine
-bloated skin
-Altered consciousness
-LOC
-no increase in body temp
Phosphates system test rest required
3-5 minutes
Test order
- Non fatiguing tests
ie: height, weight, flexibility, skin fold, girth measurement, and vertical jump - Agility tests
ie: t-test and pro agility
3.maximum power and strength tests
ie: 1RM cleans and squats
- Sprint tests
- Fatiguing anaerobic capacity
ie: 300 yard shuttle - Aerobic capacity tests
ie: 1.5 mile run, and yo-yo intermittent recovery test
Anaerobic and aerobic capacity tests should be performed on separate days from other tests when possible
What should be administered following tests that dramatically increase heart rate, or a test battery?
A cool down utilizing active recovery, light stretching and low intensity movement to improve recovery .
Interrater reliability/objectivity/ interrater agreement
Measure of consistency in test results between different raters
