Comparing The Energy Systems Used By Yourself Completing A Run / Swim / Run

Task 3 –Describe (P4), explain (M2) or analyse (D1) the importance of energy balance and their effect on sports performance.

The initial burst of speed and subsequent 5 seconds in the 100m sprint, is fuelled by the Phosphagen ATP- PC system as there is 4-5 times more Phosphocreatine (PCr) readily available in the skeletal muscles compared to that of ATP (1). The initial ATP stored is used within 2 seconds of maximal activity by the Myosin ATPase enzyme to cleave energy, leaving Adenosine Diphosphate (ADP)

During the race Mo Farah uses the aerobic system because he is a long distance runner. As the race goes on he will start to use the energy that is stored in his muscles form the food that he has eaten. His heart rate and breathing rate start to speed up to deliver more oxygen to the muscles and get rid of carbon dioxide. The body will rely on this oxygen until the last part of the race where Mo will start to pick up the pace to either overtake someone or get a faster time. During this sprint he will use the

Creatine phosphate has been heavily experimented upon to show that it is an important effector towards muscle activity. When creatine phosphate is present in a solution containing muscle fibers without the presence of ATP, it serves as the energy supplier due to the fact that it absorbs bound adenine nucleotide, which is firmly linked to the contractile elements on muscle fibers (Bozler, 1953). Even in low concentrations this nucleotide can be considered an energy transfer mechanism, for it takes full advantage of the creatine phosphates energy supply, thus acting as a substrate for the enzymatic activity of the contractile elements of a muscle group. Consumption of this nucleotide leads to an increase in the strength of contraction. Creatine phosphate also speeds up rate of relaxation of muscles, for it induces the relaxing effect of ATP (Bozler, 1953). Thus, this research suggests that creatine phosphate is directly linked to instigate muscle contractibility.

     How does Creatine work? When somebody is exercising, his or her muscles demand energy. The energy that the muscle gets is called adenosine triphosphate (ATP). As the muscles keep contracting, the ATP is turned into adenosine diphosphate (ADP). ADP causes your muscles to fatigue. Creatine Phosphate helps to convert ADP into ATP when the ATP is gone. In doing this, the athlete has better endurance during his of her workout or event.

This report will discuss the work of the energy interplay system in relation to a subject’s result in the 20 metre beep test . Energy system interplay refers to the work done by the three energy systems (ATP-PC, Anaerobic and Aerobic) to provide the body with the necessary amount of adenosine triphosphate (ATP) to complete certain physical activities depending on their intensity and duration.

Explain the physiology the cardiovascular and the digestive system in the body in relation to energy metabolism in the body. Discuss the role of energy in the body and analyse how those two body systems interrelate to perform a named functions. For distinction analyse

It is found in skeletal muscles. Creatine phosphate can house high-energy phosphate bonds. There is an abundance of ATP while the muscle cell is at rest. The creatine kinase transfers the high-energy phosphate bonds of the ATP to the high-energy phosphate bonds of the creatine phosphate. Once the cell is ready to contract, creatine kinase removes the phosphate groups from creatine phosphate and transfers them to ADP to create ATP. ATP is used to drive the contraction since it is a quick energy source. A large amount of creatine kinase should not be present in the bloodstream unless there is a large-scale destruction of muscle cells. The Duchenne muscular dystrophy causes this phenomenon to occur where muscle cell membranes are destroyed spilling out the creatine kinase into the bloodstream.

A game of touch requires the use of all energy systems at once but in varied amounts. The body will automatically choose which energy system it requires the most based on the fitness components used. It has been identified above that the three main components used by a middle are; Aerobic capacity, muscular endurance and coordination. In figure 12.5 it shows the relationship between components of fitness and energy systems. Both aerobic capacity and muscular endurance relate to the Aerobic system. The aerobic system uses oxygen and is generally one of low-mid intensity and/or of a longer duration. Middles utilise this energy system because they continuously require energy production at an almost equal rate.

The energy for all physical activity comes from the conversion of high-energy phosphates (adenosine triphosphate—ATP) to

Creatine (Cr) is a popular dietary supplement used by athletes to increase sports performance, muscle mass, and strength. Creatine was first discovered in “1835, when a French scientist reported finding this constituent of meat” (Demant & Rhodes, 1999). This organic compound is manufactured endogenously by the liver and kidneys “from the amino acids glycine, arginine and methionine” for energy stipulation during muscular contraction. (Arazi, Rahmaninia, Hoseini, & Asadi, 2011). Creatine is either converted into free form Cr or phosphorylated form as known as creatine phosphate (CP). The endogenous production and exogenous consumption of Cr yields about 1 gram a day for the average person (Cooper, Naclerio, Allfrove , & Jimenez, 2012). In

Uniquely, glycolysis is both anaerobic and aerobic. The end product pyruvate, from glycolysis, is anabolized to lactic acid when there is a need for energy without an adequate supply of oxygen available. This last step or reaction enables glycolysis to continue producing ATP without the need for oxygen, which is why it is called the anaerobic energy system (Fink, 2009).

Both Adrian and Manaudou had identical times over the 15-25 m mark, 4.5 seconds. Over this distance, Adrian took 10 strokes compared to Manaudou's 9 strokes. In the semi-finals Adrian took 9 strokes. At this point, both had tremendous stroke rates (Adrian: 133 strokes/min; Manaudou 120 strokes/min). However, Adrian's distance per stroke of 1 meter/stroke is shorter than Manaudou's 1.11 meter/stroke. The numbers suggest Adrian was "overswimming" his first 25 in the finals, taking one extra stroke compared to his semi-finals swim and 3 more strokes than Manaudou.

When I was 10 years old, my mom told me and my sister that she was going to do an Ironman. “What’s an Ironman”, I asked her, only knowing of the red and gold superhero that flies around and shoots missiles out of his arms. “Go look it up”, she responded. I-R-O-N-M-A-N I typed into Google and pressed enter. After the pictures of Tony Stark, the Ironman Triathlon link appeared. Ironman Triathlon: 2.4 miles of swimming, 112 miles of bike riding, and then 26.2 miles of running (the length of a marathon). She has always been into biking and running, but 140.6 miles of anything seems utterly absurd!
