02d. Energy system interplay

Question 1

The ATP-CP system will contribute most significantly when (provide two reasons)

Answer 1

• there has been sufficient recovery
• max intensity, short duration efforts

Question 2

The anaerobic glycolysis system will contribute most significantly when (provide two reasons)

Answer 2

• insufficient recovery
• repeated high intensity efforts (85%MHR +)

Question 3

The aerobic system will contribute most significantly when (provide two reasons)

Answer 3

• sufficient oxygen/sub max intenisty (below 85% MHR)
• after 30 seconds of activity

Question 4

Which energy system contributes most signficantly when there has been sufficient recovery for max intensity, short duration efforts

Answer 4

ATP -CP

Question 5

Which energy system contributes most significantly when there is insufficient recovery and repeated high intensity efforts (85%MHR +)

Answer 5

Anaerobic glycolysis

Question 6

Whicn energy system contributes most significantly when there is sufficient oxygen/sub max intenisty (below 85% MHR) and after 30 seconds of activity

Answer 6

Aerobic

Question 7

What is meant by interplay?

Answer 7

All three energy systems are always contributing

Question 8

Why is the aerobic system associated with longer durations?

Answer 8

Because it has a higher yield and it requires sufficient oxygen

Question 9

What can the aerobic system do when contributing most significantly at rest after high intensity efforts?

Answer 9

Replenish CP stores

Question 10

Why can’t the ATP-CP system be used for more than approx. 10 seconds?

Answer 10

Because it has a low yield

Question 11

Why doesn’t the Anaerobic glycolysis contribute most significantly for long periods of time?

Answer 11

Because it has a low yield and fatiguing metabolic by products
