Energy systems used in football
The way the body produces energy depends entirely on the intensity and duration of the exercise. During a football match a footballer would be expected to both sprint and jog around the pitch. However the player would only sprint for short bursts at a time and so this would mean that the player could sustain this throughout the match as long as he/she gave his/her body time to recover. Jogging around the pitch would allow the player to do so for a longer period of time due to the different energy system being used. This would suggest that there is a connection between the intensity of exercise and the energy system used to produce it. As the graph to the right indicates the ATP-PCr system runs out very quickly. This is why this system is used for short, intense bursts of energy, as again from the graph you can see that overall performance at its max is achieved in the first few seconds of exercise. In a football match a player produces 50% of their needed energy from the ATP-PCr system and the reason this system is used is because...
It should therefore be concluded that the ATP-PCr system is the most used energy system when playing a match of football. This is because it is vital for activities such as kicking the ball and sprinting up and down the field. The strengths of this energy source means that the player can use this system throughout the match as it is quick to re-synthesise the PC stores. However this system can only be used for up to 10 seconds at a time meaning that other energy systems will be required to provide energy when the PC stores deplete.

Lactic acid energy system
This system is also an important one as the player produces roughly 30% of their required energy from this system. This system kicks in if the stores of ATP-PCr start to run out after roughly 10 seconds. It works by breaking down carbohydrates stored in the body to...
