Quiz on VO2 and VO2 max

What is VO2?

• The greatest rate at which the body can take in and utilize oxygen

• The volume of oxygen consumed by the body during a specific period of time

• The highest rate of oxygen consumption measured during the exercise test

• The rate of oxygen utilization at submaximal exercise levels

What is VO2 max?

• The volume of oxygen consumed by the body during a specific period of time

• The highest rate of oxygen consumption measured during the exercise test

• The greatest rate at which the body can take in and utilize oxygen for the production of ATP aerobically at maximal work rate

• The rate of oxygen utilization at submaximal exercise levels

What is VO2 peak?

• The volume of oxygen consumed by the body during a specific period of time

• The greatest rate at which the body can take in and utilize oxygen

• The highest rate of oxygen consumption measured during the exercise test, regardless of whether a VO2 plateau is reached

• The rate of oxygen utilization at submaximal exercise levels

What indicates a valid index of VO2 max if an actual VO2 plateau is not reached during a test?

• The VO2 average over the duration of the exercise

• The VO2 peak attained during a maximum-effort incremental test to the limit of tolerance

• The VO2 measured at submaximal exercise levels

• The initial VO2 measurement taken at the start of the exercise test

What must a person reach to determine VO2max?

• Volitional fatigue

• A specific heart rate

• A predetermined time limit

• Submaximal exercise level

What is a true VO2max test assumed to have reached according to the criteria for reaching VO2max?

• A) A steady state

• B) A peak heart rate

• C) A specific blood lactate level

• D) A plateau in oxygen uptake

Which of the following is NOT a criterion for reaching VO2max?

• A) RER ≥ 1.10

• B) HR within 10 bpm of age-predicted HRmax

• C) Post exercise Blood Lactate > 8 mmol/L

• D) VO2 peak

Why might equations for VO2max predictions overpredict the VO2?

• A) They assume a steady state has been reached

• B) They do not account for the individual's fitness level

• C) They only measure aerobic components of exercise

• D) They are based on indirect measures

What is the preferred method for testing VO2max?

• A) Treadmill

• B) Cycle Step

• C) Ergometer Recumbent

• D) Cycle Hand ergometer

What does a true VO2max test look at in terms of exercise components?

• A) Only aerobic components

• B) Only anaerobic components

• C) Both aerobic and anaerobic components

• D) Neither aerobic nor anaerobic components
