Energy Systems Essay

This report focusses on the 3 energy systems of fitness before relating them to touch football. Touch football is a simple but fast paced game, where the main objective is for one team to score more tries then their opponent. Scoring a tri is achieved by placing the ball in the opponents ‘tri zone’. Played on a 70m long by 50m wide field over a 45-minute time period, the game consists on two 20 minutes blocks of play with a five-minute half time break.

Have you ever wondering where your electricity comes from? How your car uses gasoline to run? What about how these things impact our environment or how we are going to keep producing them? As a country, we need to start looking ahead to the future and planning for what is to come. Currently, 86% of America’s energy comes from petroleum, natural gas, and coal. All of these resources will run out eventually. We need renewable energy sources that will keep producing in a clean, more efficient way for a long time. Before committing to an idea and going all the way with it, we need to compare all the different energy sources available to the U.S. and choose the one that is best for everyone.

There are three main energy systems used in a game of touch football which consist of the creatine phosphate (ATP PC) system, lactic acid system and the aerobic system. Each system plays a vital role during game play. Every muscle in your body requires energy to perform all movements, and to do this, the energy is produced by the breakdown of a molecule called adenosine triphosphate (ATP). ATP is found in all cells which is a chemical form of muscular activity and performs mostly all functions in the human body. It contains 3 phosphate groups and adenosine. ATP is stored in the muscles and lasts for approximately 10-30 seconds. Carbohydrates, fats and proteins, are all producers of ATP from the food we eat; however Creatine Phosphate is

Before camp, I typically ran four or five miles on the days without a practice, but thanks to the training I received there, I now know how to schedule my workouts to best achieve success. Nowadays, my typical training week includes a long run, a tempo run, two scheduled practices with my team, an easy run, and a day off before a cross-country meet. I also learned what these different types of runs do. For instance, jogging over a long distance allows muscle cells to recruit mitochondria, which improves aerobic respiration, while a tempo run – running quickly for a short period of time – “flushes” the lactic acid caused by the repetitive motion of the long run. Running at

D1 outline the relationships between the cardiovascular, respiratory and energy systems before, during and after a sporting activity

The Alternative energy industry in the United States has been at a steady rate of growth for the past decade, however there is still controversy over the use of renewable energies, their impact on the economy, and their impact on the environment. As controversial as the topic is, the argument boils down to a moral need to support environmental regulations, and an economical need to sustain domestic growth in the Energy industry of the United States. Mainly, the question is can alternative energy effective replace fossil fuels? There are of course arguments for both sides of this question.

The first of three energy pathways is ATP/CP energy pathway. Adenosine triphosphate (ATP) is an organic compound found in muscle which, upon being broken down enzymatically, yields energy for muscle contraction. Creatine phosphate is a high energy phosphate molecule that is stored in cells and can be used to immediately resynthesize ATP. ATP/CP pathway provide anaerobic sources of phosphate-bond energy. The energy liberated from hydrolysis of CP re-bonds ADP and Pi to form ATP. The energy pathway can be found in such sporting events such as short sprint, shot put, softball pitch, lifting weights for three repetitions or less because they

Australians are renowned for their passion for sport, in particular, the four main football codes (Australian Rules football, Rugby League, Rugby Union and Soccer). In terms of the participation rate among these four codes, Australian Rules Football ranks second behind outdoor soccer, with 419 000 individuals or 2.6 % of the population participating in the sport. (Australian Bureau of Statistics 2009)

The MAS (Maximal Aerobic Speed) score which is derived from the completion of the multistage fitness test prior to the commencement of the program is used as the basis. Two weeks of the program are dedicated to the development of aerobic fitness since players who have a high level of aerobic fitness is capable of sustaining high level of performance for extended periods, and they are able to recover faster from intense activities such as short distance sprints than those who does not have high level of aerobic fitness (Gabbett, Kelly, & Pezet, 2007). Continuous training, including running, cycling and rowing performed at low to medium intensity are good exercise to develop the aerobic fitness. One to two times of continuous training a week would be sufficient enough to increase fitness for most players (Gabbett, Kelly, & Pezet,

When the new Southeast Polk High School opened they added many new energy saving products. This included installing geothermal heating under the high school cutting back on the cost of heating such a large building. Many new windows help save on energy used to light the building along with automatic lights that turn off after several minutes without movement. The new high school shows how easy it is to save money and help the environment. Renewable energy is good for all aspects of the U.S, providing jobs, economical growth, environmental cleanliness, and new research for improving energy efficiency. Therefore the United States should use renewable energy to benefit the economy and environment.

There are many forms of energy. The types of energy that can affect the toy car are potential energy, kinetic energy, and work of friction. Potential is the energy of an object due to its position. Kinetic energy is the energy due to motion. Friction plays a part because it shows how much energy is needed for the car to move. All these energies are intertwined in the toy car.

Long distance running is an excellent way to boost a human’s cardiovascular stamina and increase the strength in an athletes fast-twitch muscle system in his/her legs. The reason it is so effective in improving someone’s health is because it keeps the heart beating at a high rate for a long period of time. This sends oxygen quickly to all the body’s key receptors which is essential to maintain motor skills, and better a human’s growth and blood flow. It also enables the heart to adapt and strengthen to be able to handle such a strain for such a long period of time. This helps athletes keep energy during games and practice without getting as tired.

The most of global energy production produces from fossil fuel such as coal, oil and natural gas. The vast fossil fuels generate energy which use for many purposes for instant residential, transportation and industrial sectors. While the rate consumption of fossil fuel higher than their formation leads to oil price crisis. Another concern of fossil fuel combustion is the impact on the environment. Global warming is a significant problem which results in increasing concentrations of greenhouse gas in the atmosphere. These problems drive researchers and societies to search alternative energy such as switching to renewable energy or carbon-free energy to replace fossil fuels. For example Nakata et al., (2011:465) show ‘low-carbon society’

Finding energy sources is an issue that polarizes scientists, politicians and citizens alike. The most critical points of this debate are at fossil fuels and renewable energy. Energy efficiency is arguably the most dire concern facing the planet, because it significantly impacts all areas of everyday life. Common ground can be found in this controversy because both parties do agree that humans have a responsibility to future generations. That responsibility is to preserve the resources of the Earth, while offering this generation energy that is affordable and accessible.

Energy is a crucial necessity and with the ever increasing need for it and the high and fluctuating prices of oil, researchers are constantly coming up with newer and more sophisticated alternative sources of energy. However, energy comes at a cost, as it is either expensive or it possesses high health risks. This essay presents the concept of energy by discussing the two major types of energy, the various forms it could take, including renewable sources of energy, energy conservation and above all it talks about the safest and cleanest alternatives.
