Energy Systems Recap

The ATP-PC system is

• an aerobic system

• the least complicated of the three energy systems.

• the most complex energy system

• the slowest energy system

When using our ATP-PC system, our PC stores last us approximately

• 2-3 seconds

• 30-60 seconds

• 3 minutes

• 10-12 seconds

A good example of a sport that predominantly uses the ATP-PC system is

• Swimming 400m

• Running 3km

• Golf

• Triathlon

It takes approximately how long for 50% of our PC stores to replenish during a passive recovery?

• 30 seconds

• 1 minute

• 2-3 minutes

• 10 seconds

Kathy Freemans 400 metre sprint is a good example of predominantly using which energy system?

• Aerobic

• Anaerobic Glycolysis

• ATP-PC

• Lactic Acid

Our Anaerobic Glycolysis system during high intensity exercise last us approximately how long?

• 1-2 hours

• 2-3 seconds

• 60-90 seconds

• 10 minutes

For our Anaerobic Glycolysis system, every glucose molecule creates how many ATP molecules?

• 1

• 2

• 3

• 4

The Lactate Inflection Point represents what?

• An energy system

• The point in which lactate production begins to decrease at the start of rest

• Lactate build up is too much for our muscles and we have to slow down

• Maximal lactate production is being matched with maximal lactate removal

2 important factors of determining which energy system will be predominate include

• Speed and Intensity

• Fitness and Energy

• Duration and Intensity

• Duration and Endurance

Which of the following is not a fuel source for the aerobic system

• Carbohydrates

• Fats

• Sugar

• Protein
