Energy System In Football
The average football match last for 90 minutes, consisting of two 45 minute halves, with a 15 minute break in between them. Due to football matches consisting of various intensities, it is believed that all three energy systems are used: aerobic, ATP-PC and lactic acid. Here is the data that each system contributes to performance in soccer:
• ATP-PC= 60%
• Lactic Acid= 20%
• Aerobic= 20%
(Mathews 1974)
Centre backs are required to have the following components of fitness:
Component of fitness Definition Example
Cardiovascular endurance “body’s ability to continue exertion while getting energy from the aerobic system used to supply the body with energy” (Lemouse 2014) Being able to last the full 90 minutes of a match where prolonged jogging …show more content…
In terms of protein intake per day, Lemon (1994) believes that consuming 1.4kg-1.7kg of a performer’s body weight is an adequate amount for football players. Consuming this amount will allow for muscle fibres to repair effectively, allowing for adaptations such as hypertrophy to take place. Due to physical activities often stressing the ATP-PC system the rates of phosphocreatine depletion will be very high. Therefore phosphocreatine supplementation is arguably needed in order to maintain high levels of it for high intensity activities. Harris et al. (1992) found that the use of phosphocreatine supplementation was most beneficial to anaerobic activity, but also did improve aerobic activities too. Increasing phosphocreatine levels by 30% will result in less depletion as a result (Moon et al. 2007). Looking at carbohydrate intake, Balsom et al. (1999) designed two carbohydrate diets for players, one containing 60% carbohydrates and the other 30%. They wanted to manipulate muscle glycogen contractions. They conducted movement analysis, and found that players performed 33% higher intensity exercise in the game when on the high carbohydrate diet compared to those on the low carbohydrate diet. However, Ruiz et al. (2005) found that when they studied the diets of four male amateur soccer teams, the overall contribution of carbohydrates was 44% lower than what it should have been. This shows that amateur players disregard carbohydrates when it comes to their diet, and that maybe amateur players are less aware of the effect that their diet has on their performance. Mackenzie (2015) recommends these percentages of food from each group for a professional soccer
