Discuss how the energy systems might interchange in a game of soccer. Consider the different positions in your response.

In soccer the three energy systems are all used. The ATP-PC system for high intensity short bursts; the lactic acid system for intermediate bursts of longer distances, lasting about 90 seconds; and then finally the aerobic system for long efforts of low to moderate intensity. Football consists of short sprint, jogging, moderate paced running, walking and standing still. In soccer there are many different positions, all using different energy systems. The defenders stand still and but also have high intensity short busts to get the ball. This position uses the ATP-PC system. Also in soccer are the mid-fielders. These people are constantly jogging, moving the ball from the centre of the field to the goal. These people are usually the fittest on the team as they mainly use the aerobic system. Also in soccer there is the goalie. The role of them is to block off the ball from getting to the goal. This position is using the ATP-PC system as she/he is standing still most the game, only moving in short bursts when they are catching/defending off the ball. Lastly there are the forwards. The job of these people is to score the goals. The forwards are most of the time moderate paced running/jogging or short sprints to get the ball to the goal. This is part of the lactic acid system. Soccer uses the three different systems throughout the game, just depending on what position you are. In soccer the three energy systems are all used.
