Recovery and EPOC

Question 1

What happens as you increase rate of exercise / O2 consumption?

Answer 1

oxygen deficit builds up

Question 2

What is the fast component?

Answer 2

alactacid component
replenishing ATP and phosphocreatine stores
re saturation of myoglobin with O2

Question 3

What is oxygen deficit?

Answer 3

quantity of O2 that would have been used if it were available

Question 4

What is EPOC?

Answer 4

a quantity of O2 consumed post-exercise, over and above resting levels

Question 5

What is the slow component?

Answer 5

lactacid component:
removal of lactic acid
converted into urea, H2O + CO2
reconverted into glucose and glycogen to be used in Cori Cycle

Question 6

how long does fast and slow component take?

Answer 6

fast: 50% PC takes 30 seconds
100% takes 2-3 minutes

slow: 5 mins - 1 hour

Question 7

What does a performer do to allow EPOC?

Answer 7

continue to breath heavily after exercise

Question 8

Why does EPOC occur?

Answer 8

to repay oxygen debt and begin break down of lactic acid
to resynthesise ATP levels
to resaturate myoglobin with oxygen

Question 9

What is the Cori Cycle?

Answer 9

process where lactic acid is transported into the blood to the liver where it is converted to blood glucose and glycogen
