EPOC

Question 1

What does EPOC stand for?

Answer 1

Excess Post-Exercise Oxygen Consumption

Question 2

What is EPOC

Answer 2

The volume of oxygen consumed post-exercise to return to pre-exercise state

Question 3

What causes fatigue in fast and slow component?

Answer 3

Fast:
Depletion of ATP and PC
Myoglobin has lost all O2 stores
Slow:
Glucose and glycogen
high accumulated lactic acid

Question 4

What is oxygen deficit?

Answer 4

The volume of oxygen required to complete an activity entrelly aerobically

Question 5

What does fast component of EPOC do?

Answer 5

• Last 2-3 minutes
• 3-4 litres of O2
• Resynthesising ATP and PC stores
• Replenishing myoglobin levels
• Faster and deeper breathing after exercise

Question 6

What does slow component of EPOC do?

Answer 6

• Can take 1-2 hours
• Require 5-8 litres of oxygen
• Removing lactic acid (buffering)
• Lactate is oxidised
• Maintainance, ventilation, body temperature

Question 7

What are the factors that affect EPOC?

Answer 7

• Warm up: An early increase in O2 delivery will minimise the O2 deficit
• Cool down: Increases O2 delivery to tissues so speeds up fast and slow EPOC
• Specificity of training: Athletes body learn how to recover quicker through specific training
• Strategies: Use of time outs allow for recovery in certain sports
• Nutrition: Effective diet strategies before, during and after the game may delay fatigue and speed up recovery
