Energy Systems and Recovery

Explain the role of ATP in energy production during exercise.

• ATP stores and provides energy for muscle contractions.

• ATP is a waste product of energy production.

• ATP is not involved in energy production.

• ATP decreases energy levels during exercise.

Which energy system is used for long distance and endurance events?

• ATP-PC system

• Lactic acid system

• Aerobic system

What is the fuel source for the ATP-PC system?

• Glycogen

• Phosphocreatine (PC)

• Fat

How long does the ATP-PC system typically last?

• 8-10 seconds

• 30 seconds to 3 mins

• Longer than 2 mins

Which by-product of the lactic acid system is fatiguing to muscles?

• Glycogen

• Lactic acid

• Phosphocreatine

The recovery process after using the ATP-PC and lactic acid systems involves:

• Replenishing phosphocreatine stores and removing lactic acid

• Increasing oxygen intake and reducing heart rate

• Consuming carbohydrates and proteins

• Engaging in high-intensity interval training
