Exercise Metabolism

While at rest, almost all of the ATP that is used is produced by aerobic metabolism.

• True

• False

• Maybe

How much oxygen do we consume while we are at rest every minute in order for our body to sustain and produce the necessary energy need.

• 2.5 ml/kg/min

• 3.5 ml/kg/min

• 4.5 ml/kg/min

• 5.3 ml/kg/min

The energy that is needed at the very start of intense exercise is the aerobic energy.

• True

• False

In a long duration of exercise, anaerobic metabolism takes over every time the exercise increases its intensity supporting the transition from light to heavy intensity.

• True

• False

Trained individuals have a lower oxygen deficit compared to untrained ones.

• True

• False

Oxygen uptake increases rapidly during exercise but it reaches its steady state within 4-8 minutes of low intensity of continuous exercise.

• True

• False

Involving oneself to sports like basketball, volleyball and triathlon will only require aerobic metabolism to be at work in order to supply the necessary energy required on the said games.

• True

• False

The greater the exercise intensity the higher the EPOC.

• True

• False

What component of EPOC wherein lactic acid are converted into glucose?

• slow

• fast

• moderate

• very slow

In the removal of lactic acid following exercise, how many percent is oxidized and turned back into pyruvate to enter the Krebs cycle to be used as an energy substrate by heart and skeletal muscle?

• 20%

• 50%

• 70%

• 90%
