During a soccer game, each energy system is applied with various intensities from low to high that are used. It can be hard to establish which energy system is used most frequently during a game of soccer for a defender. This is because there are many different movements performed with different levels of intensity that change throughout a game of soccer. For example, a defender will usually sprint and then stop, walk, jog and then sprint again in order to get the ball from the opposing team.
A defender playing soccer will usually use the ATP/PC system first and probably the most as this system is ready for immediate movement whenever necessary. This system fuels on creatine phosphate and …show more content…
It will most likely by used when creatine phosphate gets low, which is what the ATP/PC system fuels on, so the body will move onto to the lactic acid system usually after around 10seconds of using energy because this system fuels on carbohydrates from glucose or glycogen. The carbohydrates are broken down in the body to from glucose and excess glucose becomes glycogen which is stored in our liver and muscles. Lactic acid gets produced from insufficient oxygen breaking down glucose. During a soccer game, if a defender is required to run from the goal they are defending further down the field to assist in helping out midfield and forward players with attacking the opposition, the lactic acid system could be activated if the player is running back and forth repeatedly to get the ball. This system lasts approximately 30 seconds to 2-3 minutes before the aerobic system is used. Fatigue when using this energy system can be caused by lactic acid building up in the athlete’s muscles. An effective warm down can contribute to helping the body recover by distributing the lactic acid throughout the muscular …show more content…
This is because the aerobic system is used for physical activities requiring the presence of oxygen for more than a few minutes to ensure muscular contraction is able to continue. This system is more for long endurance events such as, marathons, triathlons, swimming and cycling. In a soccer game, a defender usually won’t run at one particular speed for a long period of time like these other sports. Carbohydrates, fats and proteins are used as fuel in this system and will usually last for more than 2 hours. As mentioned earlier, in soccer, there are various types of changing movements and intensities which is why the aerobic energy system not be used as much. However, it is suggested that the player should develop a high aerobic system as it can help with processing lactic acid and increases the athletes’ ability to recover quicker when participating in high intensity sessions of sprinting in a game.
It’s crucial to view and establish the energy systems that are required in a soccer game in order to train the athlete in the correct way. All three energy systems will most likely be used during a game of soccer by a defender. An example where this can be seen is if the player does a 50m sprint during a soccer match, they can use 50% of the ATP/PC system and 50% of the lactic acid which signifies that energy systems can be used together, it’s
