VO2 Max and thresholds

Lara has been asked "how fit are you?" in order for Lara to accurately answer that question, Lara needs to determine her efficiency in what capacity?

• Running quickly while still being able to talk

• To utilise oxygen (her level of aerobic endurance) and the requirements for oxygen determined by the intensity of the physical activity.

• To convert the carbon dioxide she is emitting into oxygen

• For muscle recovery between periods of intense performance

Phoenix knows that his VO2 Max is usually 54 ml after a long, challenging run. What would his typical resting rate be?

• Around 10ml

• Around 50ml

• Around 25 ml of oxygen per minute

• Around 5

Ren and Atticus are arguing over who would have a better VO2 Max. Ren wants to do a RAMP test where the intensity is increased steadily across 10 minutes, Atticus wants to complete a 100m sprint and then test. Whose protocol will give a more accurate reading?

• Ren's because VO2 Max requires the body to be under strain before measuring efficiency

• Atticus's because a fast burst of effort is all that is required to test for a max reading

• Neither because it takes at least 40 minutes to begin hitting your VO2 Max

Jackson and Jack are trying to decide who should have the best VO2 Max without having to do a protocol. What are one of the factors that effect VO2 Max performance?

• Intelligence - because a bigger brain requires more energy

• Size of muscles - the bigger the muscle, the more oxygen required to perform well

• How long a person can hold their breath - because the more efficient a person's system, the longer they can go without breathing

• Body size variations - as a reading is expressed in millilitres of Oxygen consumed per kilogram of body weight per minute (mL/kg/min).​

Hunter has a VO2 Max of 55. There are a number of reasons for this. Factors that can influence a person's VO2 Max include:

• lung ventilation

• size and gender

• cardiac output

• heredity

• All of the above

Which of the following athletes should have the higher VO2 Max

• Charlotte - volleyball player

• Hadeel - AFL mid fielder

• Amy - 100m sprinter

• Noah - weight lifter

Maddi is trying to explain what an "aerobic training threshold" is. Ultimately, she explains that:

• It refers to a level of exercise intensity that is sufficient to cause a training effect

• The point when your energy system switches from lactate to aerobic

• The max point of performance when completing an aerobic type session

• The point where a body can no longer perform aerobically because it is too depleted

When researching key terms, Bright discovers that the aerobic training zone is best described as:

• the space in which you can talk and run at the same time

• An effort that can only be completed for a max of 90 seconds

• An effort that can only be completed for a max of 30 seconds

• a training intensity above the aerobic training threshold but below the lactate threshold.

Jake has been told that he needs to improve his sprint performance for AFL. This means that:

• Training intensities will need to be kept in the aerobic zone

• Training intensities above the lactate threshold are in the anaerobic training zone.

• Training intensities will need to be kept high for 10 minute effort only

• Training intensities need to be varied as part of his ongoing program

Josh wants to improve his fitness so that he can beat Jamie in a 5km race. In order to do this, what zone should he avoid when training?

• Anaerobic Zone

• Aerobic Zone

• Low heart rate Zone

• Hitting his lactate threshold
