C & D - Energy Systems in Sports: A Comprehensive Quiz

What is the primary source of energy for the PC energy system?

• Glucose

• Phosphocreatine

• Fatty acids

• Amino acids

Which energy system is predominantly used during high-intensity activities lasting less than 10 seconds?

• Glycolytic energy system

• Aerobic energy system

• PC energy system

• None of the above

What is a major disadvantage of the glycolytic energy system?

• It is too slow to activate.

• It produces a large amount of ATP.

• It leads to the accumulation of lactic acid.

• It requires oxygen.

Which energy system is primarily used during a marathon?

• PC energy system

• Glycolytic energy system

• Aerobic energy system

• All of the above equally

What is an advantage of the aerobic energy system?

• It functions without oxygen.

• It produces ATP very quickly.

• It can sustain energy production for extended periods.

• It does not produce any waste products.

Which sporting activity primarily utilizes the PC energy system?

• Marathon running

• 100m sprint

• Long-distance cycling

• Yoga

What adaptation occurs in muscles as a result of frequent use of the glycolytic energy system?

• Decrease in muscle glycogen stores

• Increase in oxidative enzymes

• Increase in muscle glycogen stores

• Decrease in blood lactate levels

Which of the following is NOT an advantage of the PC energy system?

• Rapid ATP production

• No waste products are produced

• Unlimited energy supply

• Does not require oxygen

During which activity would the glycolytic energy system be most active?

• Sleeping

• 400m sprint

• Slow walking

• Meditation

What is a disadvantage of the aerobic energy system?

• It is too fast.

• It requires a constant supply of oxygen.

• It only uses carbohydrates as a fuel source.

• It produces a high amount of ATP in a short time.
