1. Energy Systems (P7, M4, D2)
Name xxx

2. What is energy?
The strength and vitality required for sustained physical or mental
activity, also to digest food and simple organ processes.

3. Where do we get energy from?
We get energy from anything we digest. All foods and drinks have
calories in them, just some foods and drinks have more than others.

4. ATP
ATP, also known as Adenosine Triphosphate is the primary energy
carrier is all living organisms on earth. ATP is broken down in cells, by
hydrolysis. The braking down of ATP is essential to growth and life in all
orginisams.

5. The energy systems
There are three energy systems, they are used at different times
depending on what is needed; the amount of oxygen is needed. As part
of the cellular respiration process to generate the ATP for the muscles.
They are ATP, the anaerobic systems and the systems and aerobic
system.

6. ATP-PC System
ATP-PC contains Adenosine Triphosphate (ATP) and Phosphocreatine (PC).
This energy system provides immediate energy through the break down of
these stored high energy phosphates.
Phosphocreatine, which is stored in muscle cells contains a high level of
energy bond and when creatine phosphate is broken down during muscular
contraction, a large amount of energy is released. The energy released is
coupled with the energy requirement to resynthesize ATP.
One monocle of ATP if made from the ATP-PC system
Basketball, field events, golf swing are some sport that use the ATP-PC
system.
It takes around 3 minutes for the ATP-PC system to recover.

7. Lactic Acid System
The lactic acid system is an anaerobic energy system is which the high energy
compound adenosintriphosphate (ATP) is manufactured from the breakdown
of glucose to pyruvic acid in the muscle cells.
Less energy is made in anaerobic respiration than during aerobic respiration.
This due to the breakdown of glucose is incomplete. Anaerobic respiration
produces an oxygen debt, this is the amount of oxygen needed to oxidise
lactic acid to carbon dioxide and water.
2-3 molecules of ATP is produced.
Basketball, field events, gymnastics are some sports that use the lactic acid
system.
Recovery Time about 8 minutes

8. Aerobic Energy System
High energy phosphates are stored in limited quantities within muscle cells.
Anaerobic glycolysis exclusively uses glucose (and glycogen) as a fuel in the
absence of oxygen, or more specifically when ATP is needed at rates that
exceed those provided by aerobic metabolism.
The second and third stages of the aerobic energy system continue the
breakdown of glucose that was started by aerobic glycolysis and result in the
formation of the by-products carbon dioxide (CO2) and water (H2O), and the
synthesis of more ATP.
38-129 molecules are made in the aerobic system.
Examples of sports that predominantly use this system
Up to 10 minutes to recover

9. 100 metre race
RT 0.132
0-10 metres 1.83
10-20 metres 1.04
20-30 metres 0.93
30-40 metres 0.86
40-50 metres 0.84
50-60 metres 0.83
60-70 metres 0.84
70-80 metres 0.85
80-90 metres 0.87
90-100 metres 0.9
Time 9.79

10. 1500 metre race
First 100:ATP system, this is because its quick and short, meaning
recover is shorter.
From 100 to 1100:Aerobic system as it’s the longest part of the race,
and it’s the slowest part.
From 1100 to 1300: lactic acid system, not too long, but the runner will
be gaining speed the whole way, until they reach their top speed.
Last 100:ATP, as its recovered and its another quick, short burst.
