2. WHAT IS ENERGY?
 The strength and vitality required for sustained physical or mental activity.

3. WHERE DO WE GET ENERGY FROM?
Energy is used up all the time for body processes. The amount of energy you need depends on your sex,
age and your level of activity. Food provides energy in the body to exercise. In football you would have to
stay fully hydrated with water and eat foods with high amount of energy so you can last the 90 minutes.
We get energy from the sun which gives energy for the grass to grow, the animals eat the plants getting
energy for themselves. The human would eat the animals to get energy. We use energy for muscular
contractions and movement , we need to use energy for this as you need to move your arms and legs. We
also use it for circulation this is because the blood needs to be pumped round the body for exercise and
to stay alive. Digesting foods takes energy also.

4. ATP
Adenosine triphosphate-It serves as a source of energy for many metabolic
processes. ATP releases energy when it is broken down
into ADP by hydrolysis during cell metabolism.

5. THE ENERGY SYSTEMS
The atp-cp system energy system
Anaerobic lactic (glycolytic) energy system
Aerobic energy system
Whilst doing physical activity this is the order of the energy systems.

6. ATP-PC SYSTEM
 Creatine phosphate (CP), like ATP, is stored in muscle cells. When it is broken down, a large amount of
energy is released. The energy released is coupled to the energy requirement necessary for the
resynthesis of ATP. ... Thus, the amount of energy obtainable through this system is limited.
 Steps of the ATP-PC system: 1. Initially ATP stored in the myosin cross-bridges (microscopic contractile
parts of muscle) is broken down to release energy for muscle contraction. This leaves the by-products of
ATP breakdown: adenosine diphosphate (ADP) and one single phosphate all on its own.
 Basketball and gymnastics need atp-cp system due to the short bursts. It takes about 5-8 seconds to run
out.

7. LACTIC ACID SYSTEM
The lactic acid system is an anaerobic ener- gy system in which the high-energy compound
adenosintriphosphate (ATP) is manufactured from the breakdown of glucose to pyruvic acid in the muscle
cells. Aerobic Respiration (or cellular respiration) The energy your body requires just to live, do everyday
activities and cardio exercise such as long distance running, is generated by a sugar burning process in the
bodies cells known as aerobic respiration.
The sports that use the lactic acid system is basketball, golf swing and gymnastics. The lactic acid system is
mainly used in these sports because it takes between30 seconds and 3 minutes depending on the intensity.
There are a lot of rests in these sports or don’t last long during each competitive event. Due to this the
lactic acid system works well.

8. AEROBIC ENERGY SYSTEM
The aerobic system accesses a massive store of virtually unlimited energy.The aerobic system
produces far more ATP than either of the other energy systems. The aerobic system produces
far more ATP than either of the other energy systems but it produces the ATP much more
slowly, therefore it cannot fuel intense exercise that demands the fast production of ATP.
Glucose is then broken down by a series of enzymes. 2 ATP are used to fuel glycolysis and 4 are
created so the body gains 2 ATP to use for muscular contraction. Pyruvate is created as the end
product of the breakdown of glucose. The recovery time is 10-40 seconds.

9. 100 METRE RACE
At the start of the race the atp-cp
system, this happens immediately as a
quick burst. The energy in this system
runs out quickly, around about the 20-
30 meter mark. The sprinter will be at
his top speed at this point. The body
after this relies on using the short term
energy systems (phosphate system) to
provide energy. This then forces the
sprinter to slow down due to a build up
of lactic acid.

10. 1500 METRE RACE
In the first 100 meter race the immediate energy system is used. This means the athlete can get a good
start to the race. The short term energy system is used when the atp-cp system runs out and the race
begins to slow. This means the athlete can maintain a good place in the packn of runners and get into a
good position to sprint at the end. In the 400m the athlete continues to use the short term energy
system. This runs out in the final 100m, where they then use the immediate system to finish the race with
a flat out sprint to beat others runners and win the race.
