Energy systems Creatine Phosphate system The creatine phosphate system is an immediate energy system. ATP (adenosine triphosphate) is created without the presence of oxygen for short‚ fast bursts of power and energy. This is the first system used when performing any sporting activity. However this short burst of energy only lasts for a short moment in time for round about 10 seconds. Running events like the 100 meters sprint would be an example of using the creatine phosphate system. During the
