Aerobic Fitness Assessment Flashcards
What are the 3 systes that are part of cardiorespiratory fitness
- Pulmonary
- Cardiovascular
- Muscular
In the lungs what structures are the air sacs in the lungs that take up O2 to and release CO2 from the blood
aveloi
What is the protein-iron compound in RBC which transports O2
Hemoglobin
What is the function of the muscular system during cardiorespiratory physiology?
Uses O2 delievered by the blood to convert food into ATP through a process of aerobic metabolism
What is the purpose of exercise?
To cause biologic adaptation to improve performance/function in specific tasks
What is the purpose of exercise in a rehab setting?
to apply theraputic stress to injured or weakened body tissues resulting in physiologic adaption to improve tissue function
How is cardiorespiratory fitness measured?
Via maximal oxygen uptake & is expressed relative to body weight
What is the following a purpose of?
Response to standarized exercise stress under objective, controlled, supervised conditions
Cardiorespiratory Fitness (CRF) Assessment
What is the following an equation for?
HR x SV (L/min)
Cardiac output (CO)
What is the following an equation for?
Oxygen in arterial blood - oxygen in venous blood = oxygen that is delievered to muscle to make ATP
A-V O2
What is the normal HR range?
45 bpm (rest) - 200 bpm (max exercise)
What is the normal SV range?
50 mL (rest) - 200 mL (elite endurance athlete)
What is the average SV for a regular adult exercising?
120 mL
What are the reasons that SV increases during aerobic training?
- stronger heart musculature
- increase in total blood volume
- greater filling capacity of ventricles during resting (diastolic) phase of cardiac cycle
What is the a-v O2diff in VO2?
5 mL / 100 mL
