Aerobic/Anaerobic fitness assessment I Flashcards
What is this an objective of?
Cause biologic adaptation to improve performance (or function) in specific tasks
Exercise training
Exercise therapy imposes a theraputive stress to injured or weakened body tissues, thereby inducing physiology adaption to improve tissue function in what type of setting?
Rehabilation setting
What is the following a defintion of?
optimal functional integration of the cardiovascular, pulmonary, & musculoskeletal systems
Cardiorespiratory fitness (CRF)
Low levels of CRF are associated with what?
increased CVD mortality
Increased levels of CRF are associated with what?
reduced all-cause mortality
High levels of CRF are assoiciated with what?
higher levels of PA
What is the following a purpose of?
assess the cardiorespiratory system resopnse to standarized exercise stress under objective, supervised conditions
Aerobic exercise testing
CSF assessment involves the measurement of what?
Oxygen uptake
What is the following a definition of?
Ability of the cardiovascular & pulmonry systems to deliver oxygen to working muscles to meet PA demands
oxygen uptake
What is cardiac output
amount of blood leaving the heart per unit of time
What is A-V O2
difference in partial pressure of oxygen in arterial and venous blood
In lab oxygen intake is measured via what?
Indirect calorimetry
What does indirect calorimetry measure?
Expired air volume and gas concentrations of an exercising subject
What has the following results?
- plateau in measured oxygen uptake with increasing exercise workload
- HR that approximates age-predicted maximum
- blood lactate = about 10 mmol
- RER exceding 1.1
Maximum oxygen uptake
What are the clinical tests done during CSF testing?
- Submaximal treadmill test (Bruce or modified bruce protocol)
- Submaximal progressive cycle ergometer
What are the field tests done during CSF assessment?
- step test
- field walking test
- field run/walk tests
How long does a submaximal treadmill test typically take?
6-13 minutes
Submaximal cycling protocol
What are the watts of an untrained male and trained male?
Untrained: 50 - 100 watts
Trained: 100 - 150 watts
Submaximal cycle protocol
What is the watts for an untrained female and trained female?
Untrained: 50 - 75 watts
Trained: 75 - 100 watts
Tests to assess anaerobic training measures what?
- anaerobic power
- anerobic capacity
What is the following test called?
Subjects cycle against a fixed resistance relative to body weight for 30 seconds
Wingate Anaerobic power test
What is the following called in Wingate anaerobic power test?
indicative of atheletes ability to maintain high power output over a long duration
Mean power
What is the following called in Wingate anaerobic power test?
Correlates well with percentage of fast twitch muscle fibers
Fatigue index
