How many energy systems does the body use?
The body uses 3 different systems to supply cells with the necessary ATP to fuel energy needs. Most of the body's activities use a continuum of all three energy systems, working together to ensure a constant supply of energy.
What is the energy that the body uses?
Image Credit: lzf/iStock/Getty Images. The human body uses energy from food to fuel movement and essential body functions, but the body cells don't get energy directly from food. After food is digested, the carbohydrates, protein and fat break down into simple compounds -- glucose, amino acids and fatty acids -- which are absorbed into ...
What is the aerobic system?
The aerobic system supplies energy for body movement lasting more than just a few minutes, such as long periods of work or endurance activities. This system is also the pathway that provides ATP to fuel most of the body's energy needs not related to physical activity, such as building and repairing body tissues, digesting food, ...
Which energy system produces the most ATP?
The most complex energy system is the aerobic or oxygen energy system, which provides most of the body's ATP. This system produces ATP as energy is released from the breakdown of nutrients such as glucose and fatty acids. In the presence of oxygen, ATP can be formed through glycolysis. This system also involves the Krebs or tricarboxylic acid cycle ...
What is the body's energy source for short movements?
For short and intense movement lasting less than 10 seconds, the body mainly uses the ATP-PC, or creatine phosphate system. This system is anaerobic, which means it does not use oxygen. The ATP-PC system utilizes the relatively small amount of ATP already stored in the muscle for this immediate energy source.
Do energy systems work independently?
These energy systems do not work independently and do not function in isolation. Rather, all systems operate at all times, but some may predominate based on the body's activities, including the type, intensity and duration of physical activity as well as a person's fitness level.

Which system requires oxygen?
Unlike the other two systems, the aerobic system requires oxygen and takes much longer to overload. Sports and activities that use continuous sustained efforts such as distance swimming, crew (rowing) and sea kayaking rely on the aerobic system.
How long does glycolysis take to produce energy?
Whereas the ATP-CP system will only produce energy for 10 seconds, fast glycolysis works at capacity for as long as two minutes.
What is the energy system of the body?
There are three energy systems which convert adenosine diphosphate (ADP) back into adenosine triphosphate (ATP) for the body to be able to function, these include; The ATP-PC system also known as creatine phosphate (CP) or the phosphocreatine (PC) system, the lactate or anaerobic glycolysis system also commonly known as the lactic acid system and the third energy system is the aerobic system also known as the oxygen, or oxidative system. Both the ATP-PC and the lactate energy systems are anaerobic systems, where ATP is created without oxygen, whereas the aerobic system uses oxygen to create ATP.
How does the ATP-PC system work?
Each of the three different energy systems provides a different amount of ATP and at different speeds; Energy from the ATP-PC system can be accessed quickly as phosphocreatine which is stored within the muscle can rapidly resynthesise ATP from ADP however not much ATP is generated due to low supply of phosphocreatine. Energy from the lactate system can be accessed relatively quickly from glucose in the blood and glycogen stored within the liver and muscle. This re-synthesis of ATP from ADP occurs slower than the ATP-PC system, however generates more ATP due to larger amounts of the glucose and glycogen fuel available. The down side to this energy pathway is that the by-product lactate is produced and after 1-3minutes which reduces the ability to create more ATP and needs to be removed. Energy from the aerobic system is the preferred energy at rest and low intensity as it generates lots of ATP however does this relatively slowly from the fatty acids and glucose in the blood. This process is completed the mitochondria of the cell and continues all the time an individual is alive.
How many energy systems does the body have?
Let's break down the body's three energy systems to shed some light on the way that your body runs.
What is the dominant system of energy production?
After about 10 seconds of exertion, your body transitions to the glycolytic system, which is the dominant means of energy production for the next two minutes of exercise. If you’re running intervals or doing HIIT, this is your go-to metabolic pathway.
How does the glycolytic system produce ATP?
The glycolytic system uses carbs (in the form of blood glucose and stored glycogen) to produce ATP. Like the phosphagen system, it starts out producing energy anaerobically, but as you approach the two-minute mark, oxygen becomes an increasingly important part of the process. After about two minutes, it becomes an absolute necessity.
Why is the oxidative system called the aerobic system?
Due to the importance of oxygen for energy production in this pathway, it's sometimes called the " aerobic system ". The oxidative system uses both carbs and fat in addition to oxygen to produce ATP.
What is the molecule that makes up the body's energy?
Every process in your body—from cellular signaling to muscular contraction—runs on a molecule called adenosine triphosphate (ATP). ATP is the basic unit of energy for all living organisms on Earth, including humans, and to make it, the body relies on three different production systems (a.k.a.
What is the molecule that makes ATP?
When you start to exercise, the phosphagen system kicks into high gear, metabolizing a molecule called phosphocreatine to produce ATP. The phosphagen system doesn’t require oxygen (making it an " anaerobic system ") and works fast, but because your cells don’t store a lot of phosphocreatine, its ATP-producing capacity is limited.
What are the three metabolic energy pathways?
The three metabolic energy pathways are the phosphagen system, glycolysis and the aerobic system. How do they work, and what is their effect? Albert Einstein discovered that the total energy of an object is equal to the mass of the object multiplied by the square of the speed of light.
Where does energy come from in physical activity?
The energy for all physical activity comes from the conversion of high-energy phosphates (adenosine tri phosphate—ATP) to lower-energy phosphates (adenosine di phos phate—ADP; adenosine mono phosphate—AMP; and inorganic phosphate, P i ).
How does pyruvate produce energy?
For every molecule of glucose broken down to pyruvate through glycolysis, two molecules of usable ATP are produced (Brooks et al. 2000). Thus, very little energy is produced through this pathway, but the trade-off is that you get the energy quickly. Once pyruvate is formed, it has two fates: conversion to lactate or conversion to a metabolic intermediary molecule called acetyl coenzyme A (acetyl-CoA), which enters the mitochondria for oxidation and the production of more ATP (Robergs & Roberts 1997). Conversion to lactate occurs when the demand for oxygen is greater than the supply (i.e., during anaerobic exercise). Conversely, when there is enough oxygen available to meet the muscles’ needs (i.e., during aerobic exercise), pyruvate (via acetyl-CoA) enters the mitochondria and goes through aerobic metabolism.
Which pathway is used to produce ATP?
Like many other animals, humans produce ATP through three metabolic energy pathways that consist of many enzyme-catalyzed chemical reactions: the phosphagen system, glycolysis and the aerobic system. Which pathway your clients use for the primary production of ATP depends on how quickly they need it and how much of it they need.
Which system produces ATP?
Phosphagen System. During short-term, intense activities, a large amount of power needs to be produced by the muscles, creating a high demand for ATP. The phosphagen system (also called the ATP-CP system) is the quickest way to resynthesize ATP (Robergs & Roberts 1997).
Why is it important to understand how energy is produced for physical activity?
Understanding how energy is produced for physical activity is important when it comes to programming exercise at the proper intensity and duration for your clients. So the next time your clients get done with a workout and think, “I have a lot of energy,” you’ll know exactly where they got it.
Which reaction is responsible for the most of the cellular energy produced by the body?
The metabolic reactions that take place in the presence of oxygen are responsible for most of the cellular energy produced by the body.
