An Investigation Of Understanding Energy Systems

This energy system is fast but not as effective as it does not last for a decent period of time as the

Energy is defined as the capacity for vigorous activity, and to ensure a continuous and sufficient supply of energy for all daily activities, there are three energy systems that work together. These systems are the ATP-PC system, the anaerobic glycolytic system and the aerobic system. Each system produces a different chemical energy from different sources at different speeds. Both the ATP-CP system and anaerobic glycolytic systems are anaerobic systems, meaning oxygen is not used to synthesise ATP. As a result, these systems produce energy quicker however they do not last very long. Comparatively, the aerobic system heavily relies on oxygen to synthesise ATP. As the chemical process uses oxygen to produce energy, it is more complex than the anaerobic processes. The aerobic system takes longer to produce energy

ATP is often referred to as the energy currency of life. The cells use a form of energy called ATP to power almost all activities, such as muscle contraction, protein construction, transportation of substrates, communication with other cells and activating heat control mechanisms. Adenosine Triphosphate (ATP), an energy-bearing molecule found in all living cells. Formation of nucleic acids, transmission of nerve impulses, muscle contraction, and many other energy-consuming reactions of metabolism are made possible by the energy in ATP molecules. The energy in ATP is obtained from the breakdown of foods.

The body and cells need a constant supply of energy for a variety of reasons. Energy is needed to carry out mechanical work which involves the change in location or orientation of a body part or the cell itself. A major example is the energy required for the contraction of muscles. Molecular transport also requires energy. The movement of molecules from an area of low concentration to an area of higher concentration requires energy since this is opposite to the normal movement of molecules. This process is also called active transport. Examples include the movement of nutrient raw materials into a cell and the movement of waste materials out of the cell. Electrical work is also included under molecular transport

Oxidation of NADH and FADH2to H2O (and NAD or FAD). Generates H ion concentration gradient and therefore ATP.

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 is used to re-form the bonds between ADP and P to make ATP.

There are three main energy systems in the human body: ATP-PC, glycolytic and oxidative. They can often overlap, but one will clearly dominate depending on need.

ATP-PC - Adenosine triphosphate (ATP) is the usable form of chemical energy for muscular activity. It is stored in most cells, particularly in muscle cells. Other forms of chemical energy, such as that available from the foods we eat, must be transferred into ATP form before they can be utilized by the muscle cells.

All living cells require energy in order to proceed with cellular processes such as active transportation, and the synthesis of molecules. ATP (Adenine Tri-Phosphate) is a molecule, which provides energy in a form that cells can use for such cellular processes. Cellular

Gradual progression of exercise time, frequency and intensity is recommended for best adherence and least injury risk.

During intense activites, anaerobic energy is the major contributor for 1 to 3 minutes. Because of intense muscle contractions, there is a limited oxygen supply from the constricted blood vessels.

Although this was an extremely brief discussion of your bodies energy systems think of your energy systems by their duration and intensity. Sprinting the 100 yards require extreme bursts of energy and would favor the phosphagen system. Running the 400 yards would favor the glycolytic system. Running a marathon would require more of the oxidative system. That’s a simple way of explaining it. Also please note that these energy systems don’t occur one after the other, but each contribute at varying degrees like noted in the example

On the other hand, muscle endurance tests are longer in duration and require a constant source of energy to sustain these activities. Therefore, the predominant energy system that will be utilized to maintain these activities is the oxidative. The oxidative system can provide a steady supply of energy for hours which is needed for muscle endurance test.
