Topic 9

Question 1

Definition of fatigue

Answer 1

A reversible exercise induced decline in performance

Question 2

Name the two types of fatigue

Answer 2

Central fatigue and peripheral fatigue

Question 3

Central Fatigue

Answer 3

Develops during prolonged exercise and is caused by impaired function of the CNS

Question 4

Peripheral Fatigue

Answer 4

Develops rapidly and is caused by reduced muscle cell force

Question 5

Physiological causes of peripheral fatigue in endurance

Answer 5

Depletion of muscle and liver glycogen, dehydration, overheating and depletion of acetylcholine.

Question 6

Physiological causes of peripheral fatigue in high intensity

Answer 6

Depletion of energy sources (ATP and Creatine Phosphate)
Increase in the production of waste products like lactic acid

Question 7

Types of recovery techniques from fatigue

Answer 7

Structured Rest, Stretching/cool down, Ice bath and Nutrition

Question 8

Definition of EPOC

Answer 8

The amount of oxygen required to return the body to a resting level of metabolic function

Question 9

What happens during EPOC

Answer 9

Lactic acid is broken down and removed from the body and muscle cells are resaturated. Glycogen and myoglobin stores are also replenished

Question 10

Why does EPOC occur

Answer 10

The body enters oxygen debt during exercise leading to lactic acid build up meaning during recovery an over consumption of oxygen is required to return body to resting level

Question 11

What happens during recovery in sport

Answer 11

Removal of lactic acid
Replenishment of myoglobin
Replacement of glycogen liver and muscle stores
Replenishment of creatine phosphate
