Exercise physiology is the science that describes, explains and uses the body’s response to exercise and adaption to exercise to maximise human physical potential.
Exercise physiology is very important in touch because the amount of physical activity our body can tolerate, the better we will play for the longest amount of time.
ATP/CP system is used by the body to produce ATP quickly in the absence of oxygen. High intensity activities lasting for less than 10 seconds use this energy system as the primary source of energy. E.g. shot-put or 100m sprint.
One reaction causes ATP to break down and become ADP, releasing phosphate and energy in the process.
Aerobic system: - Requires oxygen for chemical reaction, physical activity that exceeds 5 minutes (long distance) Most important.
Anaerobic system: Does not require oxygen.
Lactic Acid system: similar to anaerobic as it does not require oxygen. It kicks in after ATP/CP system has been used. and if energy requirements are still needed by the athlete.
Chemical Formula:
ATP ADP + P + Energy

Aerobic system – when oxygen is involved, activities that are longer than 3 minutes. - After 5 minutes of exercise aerobic is most dominant energy system.
The aerobic system uses the bodies’ stores of carbohydrates, fats and proteins as the fuel to produce energy. Therefore carbohydrates are broken down into glucose and with the presence of oxygen, create energy and waste products of carbon dioxide, water and heat. See the diagram below:
Glucose + Oxygen = Energy + CO2 + H20 + Heat
