Energy Continuum (A2)

Question 1

What is the energy continuum?

Answer 1

The relative contribution of each energy system towards overall energy production

Question 2

What is each energy system dependent on in the energy continuum?

Answer 2

Intensity and duration of activity

Question 3

Intermittent exercise definition:

Answer 3

Exercise whereby the intensity alternates

Either during interval training, or during breaks in play of a game

Question 4

What are the percentages of anaerobic energy production (10, 20, 30 seconds)?

Answer 4

10 seconds - 90% anaerobic
20 seconds - 80% anaerobic
30 seconds - 70% anaerobic

Question 5

What are the percentages of anaerobic energy production (2, 4, 10, 30 60, 120 mins)

Answer 5

2 - 50% anaerobic
4 - 35% anaerobic
10 - 15% anaerobic
30 - 5% anaerobic
60 - 2% anaerobic
120 - 1% anaerobic

Question 6

What is the ATP-PC LA threshold?

Answer 6

The point at which the ATP-PC energy system is exhausted and the glycolytic system (LA) is dominant

Question 7

What is the LA O2 threshold?

Answer 7

The point at which the Glycolytic (LA) energy system is exhausted and the Aerobic System (O2) is dominant

Question 8

When is OBLA reached?

Answer 8

Blood lactate values go above 4 mmol

Answer 9

50% in 30 seconds

100% in 3 mins
