VET Sport and Rec Yr 1 - Energy Systems

Which of the following is NOT the name of an energy system

• Reactive energy system

• ATP-PC energy system

• Aerobic energy system

• Anaerobic Glycolysis Energy system

Answer explanation

The correct choice is 'Reactive energy system' as it is NOT the name of an energy system, unlike the other options provided.

The ATP-PC system is used during

• High intensity / long duration

• High instensity / short duration

• Sleeping

• Low intensity / long duration

Answer explanation

The ATP-PC system is used during high intensity / short duration activities, such as sprinting or weightlifting, due to its quick energy production without the need for oxygen.

These marathon runners would predominantly be using what energy system?

• ATP-PC system

• Aerobic system

• Lactic acid system

The recovery time of the ATP-PC system is

• 30 seconds

• 3 hours

• one day

• 3 minutes

Answer explanation

The correct answer is 3 minutes because the ATP-PC system typically takes around 3 minutes to recover after intense physical activity.

What is the intensity of the lactic acid system?

• 90-100%

• 20-50%

• 75-90%

• 50-75%

Answer explanation

The intensity of the lactic acid system is typically around 75-90%, making that the correct choice.

Carbohydrates are the predominant energy source for the aerobic system

• True

• False

Answer explanation

Carbohydrates are indeed the predominant energy source for the aerobic system, making the statement true.

The ATP-PC system uses what energy source as fuel?

• Phosphorus

• Red blood cells

• Honey

• Phosphate Creatine

Answer explanation

The correct energy source used by the ATP-PC system is Phosphate Creatine, not Phosphorus, Red blood cells, or Honey.

The lactic acid system is used during

• Moderate-high intensity / prolonged duration (90 sec)

• Low intensity / high duration (3+ hours)

• High intensity / high duration (3+ hours)

• Low intensity / short duration (10 sec)

Answer explanation

The lactic acid system is used during moderate-high intensity / prolonged duration (90 sec) activities.

The aerobic system uses oxygen

• True

• False

Answer explanation

The statement is true because the aerobic system requires oxygen to produce energy through the breakdown of carbohydrates, fats, and proteins.

What is the predominant energy system being used in this image

• Lactic acid system

• Aerobic system

• ATP-PC system

Answer explanation

The correct answer is ATP-PC system because the image shows a short burst of high-intensity activity, which is characteristic of the ATP-PC system.
