Max/sub-max Oxygen Deficit, RER

Question 1

What is sub-maximal oxygen deficit

Answer 1

When exercise begins, oxygen I cannot be aerobically distributed straight away as the circulatory system takes time to respond to the increased demand therefore energy is provided anaerobically

Question 2

What is maximal oxygen deficit

Answer 2

Oxygen deficit is bigger during maximal exercise as they are short of oxygen due to working more anaerobically

Question 3

What is RER

Answer 3

Method of determining which metabolic fuel is predominantly used during exercise

Question 4

How is RER calculated

Answer 4

Via analysing oxygen consumption and carbon dioxide production

Question 5

What is the scale for RER

Answer 5

0.7-1.1

Question 6

What metabolic fuel is used at low intensity

Answer 6

Fats - aerobic exercise

Question 7

What metabolic fuel is used at high intensity

Answer 7

Carbohydrates - anaerobic exercise

Question 8

What is lactate sampling

Answer 8

Involves taking a tiny blood sample using a hand held device to analyse how much lactate is present in the blood
