Energy Systems

Name the three energy systems mentioned in the key knowledge areas.

• ATP-CP, anaerobic glycolysis, and aerobic

• ATP-CP, lactic acid, and phosphagen

• Aerobic, lactic acid, and creatine phosphate

• Anaerobic glycolysis, phosphagen, and oxidative

Which of the following is NOT a fuel for the energy systems discussed?

• Chemical

• Food

• Water

• Both chemical and food

Explain the interplay of energy systems in relation to the intensity and duration of physical activity, sport, and exercise.

• The interplay of energy systems depends on the intensity and duration of the activity, with different systems contributing more or less depending on these factors.

• Energy systems work independently of intensity and duration, each system functioning in isolation.

• Only one energy system is active during any physical activity, regardless of intensity or duration.

• The interplay of energy systems is determined solely by the type of sport, not by intensity or duration.

Fill in the blank: The two types of anaerobic energy systems are _______ and _______.

• ATP-PC and Anaerobic glycolysis

• Aerobic and ATP-PC

• Aerobic glycolysis and ATP-PC

• Aerobic and Anaerobic glycolysis

Which of the following is a type of fuel used in the production of energy for human movement?

• Carbohydrate/glycogen/glucose

• Water

• Oxygen

• Carbon dioxide

Match the following fuels with their categories:

• Glycogen

• Creatine phosphate

• PC

• Carbohydrate

• Amino Acid

• Protein

• Triglyceride

• Fat

Fill in the blank: The two factors involved in interplay for energy production are _______ and _______.

• Yield/amount of energy (duration) and Rate/speed of energy (intensity)

• Glucose and oxygen

• Temperature and pressure

• ATP and mitochondria

Which of the following is a fuel for the ATP-CP energy system?

• Glucose

• Creatine phosphate

• Fatty acids

• Oxygen

What is measured by the rate and yield of each energy system?

• The amount of energy produced and how quickly it is produced by each system.

• The type of nutrients used by each system.

• The duration of exercise each system can support.

• The muscle groups activated by each system.

The contribution of the three energy systems at rest and during varying intensities of exercise is best described as:

• All three systems contribute equally at all times.

• The ATP-PC system dominates at rest, while the aerobic system dominates during high-intensity exercise.

• The aerobic system is dominant at rest, while the ATP-PC and anaerobic glycolysis systems increase their contribution as exercise intensity rises.

• Only the anaerobic glycolysis system is active during exercise.
