When the ATP and PC stores have run out, the energy that the body needs is provided from the lactic acid system. This system relies on the breakdown of glucose (from carbohydrates) which has been stored in the muscles as glycogen. The process by which glucose is broken down to release energy is called glycolysis. As the energy is needed quickly, and the body does not have time to deliver oxygen to the muscles, the glucose is broken down without oxygen. It is therefore referred to as anaerobic glycolysis and provides 2 ATP per glucose molecule.
What is the difference between aerobic and anaerobic activity?
The difference between aerobic and anaerobic is that anaerobic is a higher intensity with a slower duration for example a 100m sprinter only takes around 10-13 seconds however a marathon takes about 3 hours.
The 100m sprinter is working at such a fast pace they will have no oxygen as it runs out very quick the energy system this is called is Anaerobic. You need to be working from 80-100% intensity, some the activities that use this system are high jump, striker and goalkeeper in football and sprint swimmers. All of these do not use oxygen because of the intensity that they are working.
When using the aerobic energy system a person will be working within 50-80% of intensity in the activity that they are doing. A activity that uses the aerobic energy system is a marathon runner. A marathon runner needs as much oxygen as they can get as they could be running for hours at a slightly high intensity.
Explain why some activities are more aerobic/anaerobic
Some activities are more focused on one energy system that the other. The activity that you are doing will depend on what energy system you are using the most. It could be said that the shorter the activity is the energy system you will be using is anarobic . The longer that the activity is will mean the energy system you will be using is aerobic this is because the intensity is lower but the duration is much more.
Why do some sports require both energy systems
A 100m sprinter will just be using the Anaerobic energy system where a marathon runner will mainly be using the aerobic system however at the end of the marathon the runner may change the intensity and then they will be using the anaerobic system.
How does the position you play in football affect which energy system you use?
The position that you play in football will determine what energy system you use because a ''box to box'' centre midfield player will always moving up and down the pitch. The energy system that the player will use is called Aerobic, this means that the player will be working from 50-80% and they can use this energy system for hours.
If you are playing on the left or right sides in defence you will be using the Anaerobic system on an attack or defending because you will be running at full pace which is 80-100% . The players can use this energy system for around 20 seconds and gradually they will slow down and it will not be using the anaerobic system.
