Energy Systems Quiz

Which of the three main energy systems can last for the longest period of time?

• ATP-CP

• Lactic/anaerobic system

• Aerobic system

Is improved VO2 max an acute (short-term) or chronic (long-term) response to exercise?

• Acute

• Chronic

The ventricular chambers go in and out of the heart to aid blood flow. When they increase in size, what else improves? (Select all that are right)

• Increased stroke volume

• Improved cardiac output

• Increase in red blood cells

• Decreased heart rate

What is the purpose of the diaphragm?

• Controls respiration/breathing

• Pumps blood around the body

• The link between muscles and blood supply

• To power the body

When we are exercising, what is the burning sensation that eventually causes us to stop?

How long does the ATP-CP system last for in exercise, and how long does it take to fully regenerate (at rest)

• 10-15 seconds and 3 minutes

• 15-120 seconds and 3 minutes

• 30-60 seconds and 3 minutes

• As long as you work at a low intensity

When the body temperature rises during exercise, what causes it?

• ATP-CP regeneration in muscles

• Glycogen being burned off in muscles

• Energy building up in the body

• Red blood cells circulating around the body

Name the two factors in calculating cardiac output (overall performance of the heart). Write your answer as x and y

Why does respiratory/breathing rate and heart rate increase as an acute response to exercise?

• To supply working muscles with O2

• Because the body is working so hard

• Because the body gets tired

• To provide power and energy

What is the minimum amount (approximate) of time that chronic adaptations can be seen in an exercise programme?

• Six weeks

• Two weeks

• Three weeks

• 12 weeks
