Physiology report – Hockey
1. Describe (give a detailed account) the major energy system that is used in a sport of your choice?
The sport I have chosen to discuss is hockey. In the game of hockey, all three energy systems are used to create the needed energy to carry out different parts in the game of hockey. The first energy system that is used in the game of hockey is the creatine phosphate system or the CP system. The CP system provides immediate energy and ATP is produced without the presence of oxygen. This energy system is used when the exercise is of high intensity or energy needs are instantaneous. Creatine phosphate is stored in your muscles and is broken down to provide energy to make ATP. With the energy system, explosive work …show more content…
The anaerobic system becomes the main energy source until the aerobic system gets going. This energy system is for high intensity lasting up to 2 minutes. Here, ATP is made by the partial breakdown of glucose and glycogen (sugar in you blood from food and drink). This is caused by anaerobic glycolysis. No oxygen is used in the anaerobic system to create energy, however the energy produced from the anaerobic system is a by product along with lactic acid which is what makes your muscles feel tight and sore after you have done something at a high intensity for an extended period of time. If you are working too hard, the aerobic system will be unable to supply sufficient means of ATP and so eventually you will have to slow and decrease the intensity of the activity to release the excess build up of lactic acid, which means you are forced to slow down and let the aerobic system take over. In the game of hockey high-intensity activities are performed for short periods of time, for example an attack up the right hand side of the field (Depending on the situation, but if it is a run away the ATP-CP system is likely to be used but if it is a one on one or two on two situations the Lactic acid system will be used). The lactic acid system is used in this example as it kicks into gear straight away to help our bodies until the aerobic system takes over and we have enough …show more content…
The aerobic system doesn’t start instantly because it takes a few minutes for the heart to deliver oxygenated blood to the working muscles. The aerobic system produces carbon dioxide and water (H20) as waste products, which are easily breathed out or lost as sweat. The aerobic system supplies long term energy for continuous exercise and everyday movements. The aerobic system uses oxygen and if we are working below 85% of our max heart rates the aerobic system will become the main supplier of ATP for the working muscles. The aerobic system can keep supplying ATP continuously as long as we keep feeding the system with food and oxygen for its fuel. During hockey a high percent of the game is also low intensity movements such as jogging and walking, for a defender you jog or walk to mark your player and if you are an attacker you jog and walk t get into position. These low intensity long duration activities require the use of the aerobic energy system, as we breath harder and harder to try and supply the oxygen needed for aerobic respiration and after rallies we are breathing hard to supply the oxygen to help us recover so we can go and jog or walk into position once
