Energy Systems
ATP+PC, Lactic Acid (Anaerobic) and Aerobic
| Question | Answer |
|---|---|
| Name the three energy systems? | Aerobic system, Lactic Acid system, ATP-PC system |
| How long does the ATP-PC system last? | Up to 10 seconds |
| How long does the Lactic Acid system last? | From 10 seconds to 2 minutes |
| How long does the Aerobic system last? | From 2 minutes, lasting hours. (As long as there is sufficient oxygen to meet demand). |
| What fuel does the Aerobic energy system use? | Carbohydrates, Fats and as a last resort Proteins from muscles. |
| What activity or event would you use the ATP-PC system? | e.g. 100m Sprint. (Very high intensity) |
| What activity or event would you use the LA system? | e.g. 400m Sprint. (High intensity) |
| What activity or event would you use the Aerobic system? | Walking, Jogging, Cycling, Long distance events. (Low intensity) |
| What is the by-product of the LA system? | Lactic Acid |
| Which energy systems do not require oxygen? | Lactic Acid and ATP-PC (the anaerobic systems) |
| Which energy system requires oxygen? | Aerobic system |
| What is the by-product of the Aerobic system? | No fatiguing by-products |
| What fuel does the Lactic Acid system use? | Carbohydrates |
