Aerobic/ Anaerobic Muscles
Production of Lactic Acids
Lactic Acids are formed from glycogen by muscle cells when the oxygen supply is unable to support the energy production. When the body does not have enough oxygen, it is not able produce ATP. They are produced during rapid exercise. Lactic acids help improve sports preformance. Lactic acids build up when you sprint.
Mitochondria & Metabolic Rate
The mitochondra is the powerhouse of the cell. It supplys energy for the cell by digesting food molecules. It produces energy for the cell such as ATP. The Metabolic Rate is the rate at which ATP is produced.
~In soccer, players use both aerobic and anaerobic energy.
~The keeper uses mostly anaerobic mucsles while having to accomplish quick movements.
~The rest of the player such as forwards, midfielders, and defenders, use aerobic mucsles by running constantly, attacking and defending
You need lots of energy to be able to last through out the game. Many people stretch and warm up before a game because it releases lactic acids in the muscles.
Use of ATP/ Cellular Respiration
ATP is a molecule that stores energy from food inside the cell. ATP is pretty much the energy of life. All players in soccer use ATP.
It is used for kicking, shooting, running, defending and much more. When the ATP runs out the lactic acids kick in.
Cellular respiration is the process were the mitochondria captures food energy in the form of ATP. This is the way ATP is produced and used to accomplish quick movements and exploding moves.
Storage of energy in muscles in the form of Glycogen.
When a carbohydrate is digested, it is broken down into glucose. The body does not need glucose for energy so it stores the molecules in the liver and skeletal mucsles in the form of glycogen. Sometimes the glycogen stores are full and glucose is stored as fat. Glycogen is more for atheletic purposes.
The goalie uses Phosphagen energy because it requires quick, exploding movements such as jumps and dives. In other positions such as midfield, forward, and defender you need the ability to keep a steady pace while attacking and defending, they use both Glycolytic and Oxidative.
