Vo2 cards.

Vo2 Max

Is the maximum amount of oxygen the body can take in, transport and use during intense exercise. It is a measure of aerobic fitness and cardiovascular endurance.

Vo2

Is the amount of oxygen the body uses during exercise to produce energy. It is used to measure a persons aerobic fitness and endurance capacity.

AVo2 difference

The a-vO₂ difference (arteriovenous oxygen difference) is the difference in oxygen concentration between arterial and venous blood. In sport science, it indicates how much oxygen the working muscles are extracting and utilizing from the bloodstream.

Relative Vo2

The amount of oxygen used during exercise compared to a person’s body weight. It shows aerobic fitness while taking body size into account. It’s measured in millilitres of oxygen per kilogram of body weight per minute. (mL/Kg/min

Absolute Vo2

Is the total amount of oxygen the body uses during exercise, without considering body weight. It measures overall oxygen consumption. Measured in litres of oxygen per minute (L/min).

Acute Responses

Are immediate. Only last for the duration of the exercise, and consider cardiovascular, respiatory, and muscular responses. E.G Increased HR at the start of a run.

Chronic Adaptations

Long term effects. take a minimum of 6 weeks of training to develop. Circulorespiatory effects can be observed at rest, during submax exercise and during maximum exercise. Adaptations will vary and depend on what type of training is being performed. ie. aerobic VS anaerobic.

Oxygen Defecit

When exercise starts, the o2 system cannot supply enough oxygen for the working muscles.

EPOC (Oxygen debt)

Excess Post exercise oxygen consumption.

The volume of oxygen consumed after exercise has concluded, that is excess to our needs.
