VCE PE Unit 4 Chapter 8 Fatigue & Recovery

What is the definition of fatigue?

• Training at high-intensity over a prolonged period of time

• A permanent exercise-induced decline in performance

• A reversible exercise-induced decline in performance

• Pushing the body beyond its limits for a short period of time

Which describes central (or mental) fatigue?

• Rapid impaired function of the central nervous system

• Impaired function of the central nervous system during prolonged exercise

• Reduction in muscle cell force due to prolonged exercise

• Impaired function of the central nervous system due to a reduction in muscle cell force

How long does high-intensity exercise last?

• More than 1–2 minutes but less than 3–4 minutes

• More than a second or as long as 3–4 minutes

• Less than a second or as long as 1–2 minutes

• Less than a second or as long as 3–4 minutes

Which is a characteristic of peripheral fatigue?

• It develops during prolonged exercise.

• It develops rapidly and is caused by reduced muscle cell force.

• It is caused by impaired function of the central nervous system.

• It is associated with neurochemical changes in the brain.

• Central

• Chronic

• Peripheral

• Local

How is high intensity activity characterized?

• A

• B

• C

• D

Which is the physiological cause of peripheral fatigue in high-intensity exercise

• Reduction in muscle glycogen reserves

• depletion of acetylcholine

• depletion of creatine phosphate

• reduction in Ca2+ release

Which are characteristics of fatigue?

• I only

• I and II

• II and III

• I, II and III

What effects the rate of recovery?

• The type of activity

• Age

• Hydration and Sleep

• All of the above

What does EPOC stand for?

• Every Possible Oxygen Catch

• Post Exercise Cross-Over

• Excess Post-exercise Oxygen Consumption

• Extra Possible Oxygen Conserved
