1THE EFFECT OF EXERCISE ON THE BODY SYSTEMS
2 ADENOSINE TRIPHOSPHATE
- This is a chemical component which is necessary
for the body in order to supply energy. - The body has only one possible energy supply
which is ATP. - Only a small supply of ATP exists in the
muscles, therefore it is important to re-produce
a supply of ATP.

The body has three systems which create or
reproduce the ATP.
The CREATIN PHOSPHATE system
The LACTIC ACID system
The AEROBIC system

energy The body reproduces it in three ways.

ENERGY SYSTEMS LONG TERM NO OXYGEN DEBT
6Creatin Phosphate System
- This is a compound high in energy, which is
stored in the muscles. When it is broken down it
gives us enough energy for about 5 10 seconds
of hard work. - The energy from the creatin phosphate system is
available instantly, but the supply runs out very
quickly.

This energy lasts for about 10 seconds. Name the

8Lactic Acid System
- This system supplies energy until there is enough
oxygen available for the muscles. It uses
glycogen which is stored in the muscles and the
liver. - It produces enough energy but produces lactic
acid which causes pain in the muscles. This
system is important when trying to work at a high
density for a period of 90 seconds to 2 minutes.

10Aerobic System
- Energy from this system in nearly endless. When
there is enough oxygen available for the muscles,
energy is available by breaking down
carbohydrates and fat. - We use this system in light activities. It
provides energy which is too slow for explosive
activities. But it is important for athletes
and players who need a constant source of energy
in low, light or medium density activities.
