The aerobic energy system

The lactic acid system

• is used during activities like golf and cricket.

• is an excellent source of energy with no limitations.

• uses carbohydrate as its fuel source.

• causes a decrease in ATP production.

Fat is used as a fuel source for resynthesising ATP when

• exercise intensity is high.

• an athlete completes a 100 metre sprint.

• exercise intensity is low.

• there is not enough protein available.

Energy systems

• help the body breakdown carbohydrate, fat and protein.

• use carbohydrate, fat and protein to build muscles.

• use oxygen to convert ADP to ATP.

• use carbohydrate, fats and protein to resynthesise ATP from ADP and P.

When using the ATP–PC system, it is important to

• keep activities between 10–15 seconds and allow 2–3 minutes of rest between efforts.

• keep activities less than 30 seconds and allow 2–3 minutes of recovery between efforts.

• keep activities between 10–15 seconds and allow a work to rest ratio of at least 1:4.

• keep activities less than 30 seconds and allow a recovery of at least 1:4.

Over the course of an on-court game, an athlete who is playing basketball will

• (A) predominantly use their ATP–PC system for energy.

• (B) predominantly use their lactic acid system for energy.

• (C) predominantly use their aerobic system for energy.

• (D) use a variety of energy systems depending on the actions they are completing.

Training at under 85% maximum heart rate will predominantly use which energy system?

• (A) The ATP–PC system

• (B) The lactic acid system

• (C) The aerobic system

• (D) The muscular system

Which of the following would NOT be used to provide energy to an athlete playing the centre position during the first quarter of a netball game?
