CAT 2 - Energy Systems Redemption

Which of the following lists accurately describes characteristics of the ATP-PC system?

• Provides immediate energy, uses phosphocreatine, anaerobic, short duration, high intensity

• Uses oxygen, long duration, low intensity, slow energy release, uses fats

• Produces lactic acid, moderate duration, moderate intensity, uses glucose, aerobic

• Requires carbohydrates, slow to activate, low power output, uses protein, aerobic

Which of the following lists characteristics of the anaerobic glycolysis system?

• Produces energy without oxygen, short duration, high intensity, produces lactic acid, limited ATP yield

• Requires oxygen, long duration, low intensity, no lactic acid, unlimited ATP yield

• Uses fat as primary fuel, slow energy release, no lactic acid, high ATP yield, endurance activities

• Produces energy with oxygen, moderate duration, moderate intensity, no lactic acid, high ATP yield

Which of the following lists characteristics of the aerobic glycolysis system?

• Produces ATP in the presence of oxygen, slower energy release, used for prolonged activities, produces carbon dioxide and water, occurs in the mitochondria

• Produces ATP without oxygen, rapid energy release, used for short bursts, produces lactic acid, occurs in the cytoplasm

• Requires no oxygen, produces only lactic acid, used for explosive movements, occurs in the nucleus, limited ATP production

• Produces ATP only during rest, does not produce any byproducts, used for anaerobic activities, occurs in the ribosomes, unlimited ATP production

The ATP-PC system helps an elite 100m sprinter by:

• providing immediate energy for short, explosive efforts

• supplying energy for long-distance endurance events

• breaking down fats for sustained energy release

• relying on oxygen to produce energy over several minutes

If the body is using anaerobic energy, it means:

• the body is producing energy without using oxygen.

• the body is using only fat for energy.

• the body is producing energy with the help of sunlight.

• the body is using only carbohydrates for energy.

Pick a sport that would use the aerobic energy system and discuss how it would be utilised.

• Marathon running

• 100m sprint

• Shot put

• Weightlifting
