Topic 9 Fatigue

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.
