Why are energy systems important?
Understanding energy systems underpins the study of exercise and the effect it has on the human body.
Bio-energetics. or the study of energy flow through living systems is usually one of the first chapters in any good exercise physiology text. But the current model of human energy systems is being challenged...
Recent research and practical experience expose its limitations, in particular with regard to fatigue.
How the various systems in the human body are interconnected and why it is important for health workers to understand the connections and the positioning of bodily systems in relation to each other?
Our body systems work together in several ways. for example if a person is exercising their somatic nervous system will tell the skeletal muscles to start working. the working muscles will demand energy . the energy will be produced by ATP in the cells. the cardiovascular system will have delivered oxygen and glucose to the cells where ATP is produced.
In reality closed systems do not exist. In the theoretical case of a closed system the total energy of the system would stay the same (matter and particles are considered energy to). More important: the energy level throughout the whole system will eventually be evenly spread and uniform (entropy), therefore no energy differential is left to perform work.
Coenergy (or co-energy) - a non-physical quantity used in theoretical analysis of energy in physical systems. The concept of co-energy can be applied to many conservative systems (inertial mechanical, electromagnetic, etc.), which can be described by linear relationship between the input and stored energy.
