Cardiovascular Exercise and Energy Systems Quiz

Which of the following is a misconception about cardiovascular exercise?

• Cardiovascular exercise can completely eliminate the risk of heart disease.

• Cardiovascular exercise reduces the risk of heart disease, but genetics and diet also play a role.

• Cardiovascular exercise increases airway resistance, making it harder for respiratory muscles to work.

• Cardiovascular exercise allows a person to eat whatever they want without consequences.

• 2-3 hours

• You should exercise immediately after eating

What is the primary energy source for high intensity activities of short duration, such as sprints or a 1RM bench press?

• Marathon

• Hiking

• Boxing (3 minutes rounds)

What is the maximum amount of time ATP can provide energy for high-intensity activities before it is resynthesized from CP?

• 1-2 seconds

• 10 seconds

• 3 minutes
