Javelin: The Three Energy Systems Used In Sports
Javelin is a Track and Field event that uses various energy systems and muscles. The three energy systems used within all sports include:
• ATP – PC System (Anaerobic System): This system works by breaking down food energies (stored in the cells) to produce energy and Adenosine Diphosphate (ADP). From here Phosphate Creatine (found in muscles), a chemical compound, combines with ADP to produce more ATP. This system is used best for high intense events using large bursts of energy.
• Lactic Acid System (Anaerobic System): The Lactic Acid System is‘a fatiguing metabolite of the lactic acid system resulting from the incomplete breakdown of glucose’ (Matthews.D, 2008). This system is used for predominantly intermediate events such as a Rugby

    ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP, NADH, and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not, enzymes are mediated in the cytoplasm. The electron transport chain, chemiosmosis, and aerobic respiration use NADH molecule (which it main purpose is to transport electrons form one molecule to another) for later purposes. The mitochondrial matrix receives pyruvate from the cytoplasm after it crosses over the mitochondrial membrane. When the pyruvate enters the Krebs cycle it goes through many stages of biochemical enzyme-catalyzed reactions. In more detail about the cycle its main purpose is to produce little amounts of ATP by removing carbon dioxide and hydrogen from pyruvate molecules. Within the inner membrane of the mitochondrion the electron transport chain and chemiosmosis synthesis ATP with hydrogen ions which are NADH and FADH2. The Krebs cycle and glycolysis produce less ATP because chemiosmosis synthesizes a great amount of ATP.…

    p4 explain the physiology of two named body systems in relation to metabolism

    The cardiovascular system carries oxygen and glucose to the cells and transports waste products such as co2 and urea away from the cells and to other parts of the body, such as the lungs and kidneys. Adenosine triphosphate, also known as ATP, is a chemical energy that is produced when nutrient molecules are burnt. ATP is constantly being produced on a daily basis due to the breakdown of glucose. Glucose is a sugar which is the main source of energy for the body. Glucose is broken down and the energy from the glucose molecule chemical bonds are released and utilized by the cell…

    Touch Football Training Program Analysis

    In a normal game, the anaerobic system would be used on average 20% of the time and the two anaerobic systems would be used for the remaining 80% of the time. The first system to be used is the ATP-CP system which lasts for a short period of 0 to 10 seconds and does not require oxygen. This system is used for high-intensity activity, particularly in touch used during a game if a player makes a break, or is running after a player, any short sprints or getting on side (Touch Football, 2015). After this system has finished, the lactic acid system begins also without the presence of oxygen, which lasts from 10 seconds to 2 minutes until lactic acids begins to kick-in as a by-product. In touch, this system is utilized during most fast paced plays for example; repetitive rucks or further distanced sprints. The aerobic system is then used to resynthesise the ATP required for the anaerobic systems. In order to monitor any progress made, specific fitness tests will be completed before and after the program. As my fitness levels are average, it is important to focus on increasing my aerobic…

    Worksheet On Cellular Respiration

    All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in envi¬ronments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this activity you will begin to look at the aerobic and anaerobic processes that are…

    Great metabolic race essay

    By 5 minutes once the athlete gets settled into a steady pace, aerobic pathways begin to take over. This aerobic pathway involves the catabolism of glucose, as a fuel. Reliance on glucose is due to the ability to produce a lot of energy in a relatively short time span. The glucose stores in the body of the athlete are located mainly in the liver and muscles; the liver which acts to regulate blood glucose, and muscles for the excess work that is performed which…

    How the integration of all the systems contribute to normal functioning.

    All parts of the human body are extremely different and each one complex in the way in which they functioning. The integration of the eleven systems of the body are all essential for normal functioning and need interact to maintain a healthy body. An example of integration, is the respiratory system and the circulatory system. The respiratory system brakes down Oxygen (O) taken into the body. After this action has taken place, the Oxygen is then passed into the circulatory system to be transported around the body to provide cells with energy. This energy is called Adenosine triphosphate (ATP), without this energy the body and its functioning would fail. After Oxygen has been distributed around the body the waste product Carbon Dioxide (C02), is taken back to the respiratory system via the circulatory system to be excreted from the body.…

    Energy transfers which take place in living organisms

    Living organisms including all plants and animals require energy for their cellular processes. In biological processes, the immediate energy source is often in the form adenosine triphosphate (ATP). The nucleotide ATP maintains both catabolic and anabolic reactions. An example of a catabolic reaction is respiration where large molecules are broken down into smaller ones with energy released. An example of an anabolic reaction is photosynthesis where small molecules are built up into larger ones using energy. ATP is built up from ADP and inorganic phosphate ions (3-4 PO, abbreviated to Pi) by condensation and is then hydrolysed by the enzyme ATPase to ADP and Pi to release energy that can be used for energy requiring reactions such as photosynthesis in plants.…

    energy systems

    In the 5000m race the runner must use all 3 energy systems , which are ATP, aerobic and lactic acid systems to succeed as the race has different areas needed for their use, all 3 energy systems contribute regardless of the intensity or duration of the exercise. When the athlete comes to the starting line he/she most probably will want to make a dashing start to the race to tactically get a good starting position, so must get off the line, in the first 40-50m, as hard as he or she can. By getting off the line as fast as the athlete can, they will both set themselves up with a good strong fast early rhythm, but also by getting near to the front of the pack they will be able to choose their position in the early portions of the race. But to achieve take off and the short sprint they must use the creatine phosphate system which uses ATP molecules as energy for any muscle contraction to occur, obviously when exercising at a high level like sprinting more ATP are needed to supply the energy, but because stores only last for up to 4 seconds the body needs a system that can re-synthesise adenosine die phosphate in to Adenosine tri phosphate very quickly when an individual starts to exercise. Carbohydrates, fats and proteins are digested to provide a source of energy. Carbohydrates are usually in the short term and fats are mainly used in the long term, protein is used as a stand by source of ATP. To get carbohydrates we can eat foods such as potatoes, rice, bread and fruit, and when they are digested they release glucose which is then stored in the body as glycogen, to supply energy to the phosphates, this is known as anaerobic glycolysis, and also used when exercise is at high intensity. The athlete does need to be weary of how long they use this system at the start of the race because could run out of fuel to supply the ATP which can only run anaerobically for up to 3 min which would lead to an unwanted substance early on in the race called lactic acid which would…
