Excerpt from the course
ENERGY SYSTEMS IN THE HUMAN BODY
When a movement occurs in the human body, energy must be released to cause that movement. Energy is stored in the body in a molecule called adenosine triphosphate (ATP). To release the energy, a chemical reaction occurs, which converts the ATP to adenosine diphosphate (ADP) plus a free phosphorus, and large amounts of energy. The energy produced is primarily motion (ie. the movement of muscles), and heat (which is lost). The body’s use of energy is not particularly efficient, as a lot is usually lost during any movement.
The small amount of ATP in muscle is only sufficient to support a single explosive muscle contraction, such as throwing a ball or a golf swing. If sports, or some other performance, demands repeated muscle contractions, the ATP required must be constantly replenished from other fuel sources in the muscle. ATP is stored in every cell of the body, and is able to be transported throughout the body.
The result of muscle contraction produces ADP which when coupled with phosphocreatine (PCr) regenerates ATP. PCr is stored in the muscles. Muscles that are working hard obtain ATP from glucose stored in the blood stream and the breakdown of glycogen stored in the muscles. Exercise for longer periods of time requires the complete oxidation of carbohydrates or free fatty acids in the mitochondria.
Sources of Energy in the form of ATP
ATP can be supplied to the body by three different ways. If oxygen is involved, the system is called aerobic respiration. If no oxygen is involved, it is termed anaerobic respiration. Different sports will convert ATP to energy in different ways, and effective training will alter the way ATP is converted to energy to make it more efficient.
1. ATP-PCr System (An anaerobic system)
Here the compound phosphocreatine is broken down to produce ATP. When phosphocreatine breaks down it produces phosphorus, creatine, and energy. The energy produced is then able to be used with ADP to create ATP. Phosphocreatine is then able to be reconstituted with the addition of energy (which comes from foodstuffs - not from stored ATP/ADP reactions). These sources of energy are quickly rebuilt after effort, to the extent that 50% of the energy source is available around 30 seconds later, and 80% of this energy is restored within two minutes.
2. Lactic Acid System (An anaerobic system)
When a maximal effort is continued beyond the extent of the of the phosphate energy system, energy is provided from glycogen stored in the muscles. This system involves glucose (or glycogen) going through various chemical processes to produce ATP plus lactic acid. Where inadequate oxygen is available to meet the demands of the muscles during exercise, or to allow aerobic glycolysis to occur, ATP is still formed - but it produces a by product known as lactic acid. The amount of ATP produced in this way is small. This is a more complex procedure using only carbohydrates as its food fuel, and not requiring oxygen for the process.
This energy is used for example, in 400 metre track races and 100 metre swimming events. Continuous activities which lead to exhaustion in 45-50 seconds result in maximal values for lactic acid accumulation. A problem with this process is that it can affect blood pH. Blood pH should be around 7.3, and never drop below 6.8. The lactic acid system is however self limiting, and should not normally develop such problems. Generally the result will be a feeling of fatigue which will cause an athlete (or someone doing heavy bursts of work) to slow down. Once lactic acid is produced, it requires 45 to 60 minutes to be removed, and for the athlete to recover.
3. Oxygen System (An aerobic system)
This process involves the formation of carbon dioxide, water and ATP, from fats, proteins and/or carbohydrates, in the presence of oxygen. This process can produce large amounts of ATP. One molecule of sugar can result in the production of 36 molecules of ATP. This is more complex than the ATP-PCr system. The only limiting factor for this system is usually the supply of oxygen.
The body will normally try to use this system first, and only use other systems to produce ATP if oxygen is in short supply. The short supply of oxygen can occur when:
- Activity first starts
- Activity is placing higher demands on oxygen than what can be supplied by breathing.
The Krebs Cycle is part of aerobic respiration, but we won’t be examining this directly in this course. You may like to do extra reading on the Krebs Cycle which is also known as the citric acid cycle. You will find information on the Krebs cycle in most high school biology text books, reference books, or on the internet.
Aerobic vs. Anaerobic Respiration
The body uses anaerobic systems for energy supply only when aerobic systems cannot meet the demand. If muscles cannot get enough oxygen to continue with aerobic respiration, then anaerobic respiration will start.
For example: if a person is running a marathon, breathing may not be supplying ample oxygen to produce ATP through the aerobic system, hence the lactic acid system may start to be used, resulting in a build up of lactic acid OR the ATP-PCr system may be used resulting in a depletion of Phosphocreatine in the muscles. After completing exercise, there may be a lactic acid build up, and if so, the body needs to remove this excess. This lactic acid removal requires energy which is supplied aerobically; hence extra oxygen may be required. This extra oxygen requirement (after exercise) is called the "oxygen debt".
Training usually aims to extend how long the body can function aerobically before anaerobic respiration commences.
THE CALORIC COST OF EVERYDAY ACTIVITIES
The following table provides an idea of the number of calories per minute that are consumed whilst performing a variety of different activities. All values include the resting energy expenditure, which is how much energy would be consumed if the athlete were resting anyway.
EBOOK TO COMPLIMENT THIS COURSE
Discover a better understanding of food and nutrition, what to eat and what to avoid. Human Nutrition is an ideal introductory text for students and anyone else interested in learning how diet and harm or help human health.
by the Staff of ACS Distance Learning
Human Nutrition eBook course online. It's surprising how little most people know about the human body and how it works. If we all spent just a small amount of time educating ourselves, we would save years in terms of health problems and hundreds of pounds otherwise spent on health care.
Throughout history there has been a vast array of nutritional claims and dietary advice. For example, there is evidence of dietary regimes involving fasting as far back as in Ancient Greece and many examples since of diet being used either to restrict intake to lose weight or to act as a cure for a medical complaint. This book will give you the background necessary to understand these theories and make better choices for yourself.
