Task 2 – Describe (P3) or explain (M1) the concept of energy intake and expenditure in sports performance.
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
Evaluation of the Components of Fitness and an Analysis to Their Relevance of Touch Football
After being established in the 70’s, Touch Football is now played in every state of Australia and is ever increasing in popularity. Touch is a fast paced, thrilling sport that allows people of all ages to get involved with a rugby league style game without the major contact required in normal Rugby. Coaches for both league and union utilize many variations of touch at training as it can be used to improve skills while also having contact removed to avoid the possibility of injury. The overall aim in a game of Touch Football is for your team to score more touchdowns than your opponents. This is achieved by placing the ball in your opponents `Touchdown Zone. Touchdowns can be scored in a multiple amount of ways like rucking, wrapping and switching the ball to create space to score.
For this term’s HPE unit, we have learnt about core physiological principles as well as fitness and training concepts, and how this would relate to touch football. This knowledge was then utilised to design, evaluate and modify an individual one week training program (microcycle) to enhance performance in touch football. The task of this assessment is to analyse the training program upon completion, by evaluating its strengths and weaknesses and finally modifying this ‘microcycle’ to rectify any weaknesses that may have be identified.
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.
Metabolism comprises of a vital set of biochemical reactions that all living organisms require to sustain life. For a marathon runner, their physiological response to strenuous exercise depletes both their fats and carbohydrate storage in order to supply energy in the form of Adenosine Triphosphate (ATP). ATP is the energy form that the human body uses for biological processes such as movement and synthesis of biomacromolecules. In regards to running a marathon, the athlete is capable of using a combination of both anaerobic and aerobic pathways, but these different systems predominate at different intervals in order to increase the energy allowed for the muscles.
This energy system only lasts for 10 seconds. It is used for high intensity, short duration activities e.g. 100m sprint, weightlifting, shot putt
* An explanation of the physiology of two named body system, and their role in the utilisation of energy in the body. An examples of 2 systems the you could discuss are as
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.
This information is about training and development that I write as a trainer of a person who wants to improve some skills of touch football. To aims to improve the performance of individual and groups within organisational settings. Doing activities under the training programs could be one of the most important session that might help your improving much easier and quicker. So that, the trainer and peers have to understand it properly further to get improved effectively. First of all, to develop their skills certainly the couch need to identify the players to discover a better training as a premise that the trainer is familiar about the training and couching even though the trainer can’t perform and is not really familiar about the activity.
Activity thermogenesis is the energy exhausted through exercise (Brown et. al., 2011). This is also for non-exercise activity such as fidgeting (Brown et. al., 2011). Activity thermogenesis accounts for 20-40% of the total energy expenditure in the body (Brown et. al., 2011).
An individual engaged in vigorous exercise demands much more energy than a sedentary individual. The supplied energy during a 100 meter sprint or a marathon run comes at a cost, which is the production of ATP (Hill et al.). At the beginning of exercise the body relies on the glycogen stores in muscle that aids in ATP production. Eventually, glucose levels in muscles begin to decrease as the activity continues, it’s also thought that insufficient glucose causes tiredness (Hill et al.) . Glucose must be provided continuously in order to satisfy one’s energy demands. Consequently, glucose is delivered by blood to the muscles. Fatty acids also contribute to the process of generating energy when glucose levels are low, which are broken down to
Write a short paragraph that defines VO2max, explains what it measures and describes some of the most important ways that it can be used in health and sport.
Three different metabolic energy systems power your workouts — and your day. Here’s how each one works, and how to make the most of them all.
