THE EFFECT OF EXERCISE ON THE BODY SYSTEMS

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

Creatin 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.

8
Lactic 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.

Aerobic 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.
