All living organisms need energy to survive, all the basic functions of a human to survive need energy, to maintain them from not stopping. e.g. breathing, the heart beating, moving etc. The whole body needs energy, otherwise it wouldn’t work, and we get our energy from eating foods and drinking. The food and drink goes into our stomach and from there it is digested, absorbed, then either stored or converted into energy by chemical reactions in our body, therefore food is chemical energy.
Energy Systems D2 After I analyse each aspect of the energy systems I will then explain why they are so vital in helping us when participating in sporting activities. First lets start by looking at what ATP is. Adenosine Triphoshate, better known as ATP is the energy our body uses willingly to create movement such as contractions in the muscles. ATP consists of one adenine and three phosphate molecules. It is produced through the breakdown of foods that we eat.
They tend to enlarge following vigorous exercise, a phenomenon called muscular hypertrophy and are located around the body. Conversely, cardiac muscle is confined only to the heart, its main role being to distribute blood. Its myogenic nature means contractions are under involuntary control and cause prevention from fatigue. The natural beating rhythm is adjusted via sympathetic and parasympathetic neurons of the CNS to suit physiological conditions. The function of these muscles is closely related to their structure and any differences in structure allow these two types of muscle to be identified.
Size of muscle cells and the ability of nerves to activate them are related to muscle strength. Fitness training method: The perfect fitness training method for this specific component of fitness would be core stability training. Core stability training trains and builds core, muscles, which are lower and upper back muscles. This type of training helps to maintain body balanced. (M2/D1) Evaluate one method of training, for all components of fitness There is only one method of training, which involves all components of fitness, and trains all body parts.
We need energy to move our muscles which also only operate when they are warm. Coldblooded humans use the energy from the environment as well as from their food. Energy is the capacity to do work in our bodies. That means doing everything that a body needs to do to stay alive and to grow: pumping ions across membranes, making new proteins, making new lipids, making hormones, making new cells, neural function, contracting muscles, replacing damaged or worn-out components, absorbing nutrients, excreting wastes and pumping blood. Supplying enough energy to support the many functions of the body at work and play is one of the chief functions of food.
Lavena Womack Journal Analysis 1 "Wellness Counseling: The Evidence Base for Practice" The article, Wellness Counseling: The Evidence Base for Practice, was written by Jane E. Meyers and Thomas Sweeney. The article consists of two concepts that provide a layout for wellness in the counseling field. The two models for wellness discussed in the article is The Wheel of Wellness and the Indivisible Self models. Throughout the article, Meyers and Sweeney discusses how wellness is a dynamic process of physical, mental and spiritual optimization and integration, and how asserting wellness will provide more of a strength-based strategy when assessing clients and optimizing their growth. Prior to reviewing the article, my sense of wellness was that it was an active process, such as exercising or praying, to become more aware of one self in order to make better choices toward a more successful existence of life.
“The muscles are no different. When muscles work, they require energy so that they can contract. The unique feature about muscular contraction is that the chemical energy is transformed into mechanical energy – movement.” (http://www.nsbri.org/humanphysspace/focus5/epenergetics.html/20/11/2011/) Although extended
P4- Explain the Physiology of two named body systems in relation to energy metabolism in the body. In this essay I am going to be explaining how energy is made in the body and two body systems that help to produce this energy. “The metabolic systems are responsible for the chemical reactions within the body. These reactions are involved in the maintenance of the living organism and may be involved in reactions that break compounds down catabolic reactions or reactions which build compounds up anabolic reactions”. (King R 2012) They all require energy to work.
The body receives oxygen from the lungs and transmits it to your muscles through your bloodstream. The heart controls the flow of blood throughout the body and your heart rate is a factor of that flow. Therefore when your muscles work harder and require more oxygen, your heart rate increases to meet the needs to maintain a consistent internal state, the harder you work the faster your heart pumps. The probable homeostatic responses to changes in the internal environment during exercise to the breathing rate, exercise will increase the demands on your body to supply the fuel it needs to perform. Your body’s need for oxygen will increase.
The two body systems I will write about are the respiratory system and the digestive system. Respiratory system: The respiratory system comprises of the nose, mouth, throat, larynx, trachea, bronchi and lungs. The function of the respiratory system is to facilitate gaseous exchange to take place in the lungs and tissue of the body. Oxygen is required by cells to allow various metabolic reactions to take place and to produce energy which is essential to life. Internal respiration involves chemical activities that take place in every living cell requiring oxygen and glycogen to combine to release energy, water and carbon dioxide.
