Aerobic and Anaerobic

Question 1

What does Aerobic mean?

Answer 1

Aerobic
- When O2 is present
- Long distance events (3mins+)
- Low/Moderate intensity
- Enough O2 to supply muscles

Glucose + Oxygen –> Energy + Water + CO2

Question 2

What does Anaerobic mean?

Answer 2

Anaerobic
- When O2 is not present
- Short events (Up to 30 seconds)
- High intensity events
- Demand is too high (Oxygen debt)
- Event finishes before oxygen can reach muscles

Glucose –> Energy + Lactic Acid

Question 3

Define Oxygen Debt

Answer 3

Oxygen Debt
- Lack of Oxygen + build up of Lactic Acid causes fatigue
- Anaerobic systems require O2 to restore them
- When a person stops exercising, they will breathe deeply + rapidly to restore O2 levels in the body
