Energy: How Does My Body Get It and How Does It Use It?

Many times citizen will ask an energetic man they know, where do you get all that vigor from?? We just assume they plainly have an overactive and limitless provide of vigor which we are just not capable of having ourselves. We may ask ourselves, why is it that when I rehearsal I seem to run out of gas and get tired after thirty minutes but that guy over there seems to be able to keep at it for well over an hour without tiring out? Is he just a more energetic man than me? Why can't I have that kind of vigor when I exercise? What is his secret?

Well, suppose I said, "He has no secret" and "you too can get more energy" and without any magic potion or incommunicable tricks known only to a pick few people. plainly having a basic insight of how your body works and what it needs to make it work at its best will help you to see what may be "the key" to obtaining best vigor levels that will have citizen request you what your incommunicable is.

In order to build biomolecules and keep life, your body needs energy. The body gets its vigor from the breakdown of nutrients like glucose, amino acids and fatty acids. To build molecules there must be molecular destruction going on simultaneously to provide the vigor required to drive these biochemical reactions. This is an ongoing process that occurs throughout the day.

It must be understood that anabolism (building of tissue) and catabolism (breakdown of tissue) occur simultaneously all the time. However, they differ in magnitude depending on the level of activity or rest and on when the last meal was eaten. When anabolism exceeds catabolism, net growth occurs. When catabolism exceeds anabolism, the body has a net loss of substances and body tissues and may lose weight.

With regard to how your body uses what you give it reconsider the following.

The fate of an amino acid after it is movable to the liver is highly dependent on the body's needs for that moment. Some amino acids enter the blood stream, where they join amino acids that have been liberated during the constant breakdown and synthesis of body tissue. Other amino acids are used by the liver to build many of the specialized proteins such as liver enzymes, lipoproteins, and the blood protein (albumin). As these amino acids circulate throughout the body, each cell directed by its own Dna blue print, draws from the common pool of available amino acids to synthesize all the numerous proteins required for its functions.

In order for protein synthesis to occur, an enough provide of both requisite (not produced by your body) and non-essential (produced by your body) amino acids is vital. If one of the requisite amino acids is missing then synthesis is halted. These partially assembled proteins are disassembled and the amino acids returned to the blood. Any amino acids that are not used within a short time can not be stored for future use. They are delivered back to the liver and stripped of their nitrogen, then incorporated into urea and excreted by the kidneys. The remaining protein skeleton will be converted to glucose and burned as vigor or converted to fat or glycogen for storage.

Although protein synthesis is very important, the body's amount one priority is to acquire enough vigor to carry on vital functions such as circulation, respiration and digestion. Therefore, in the absence of enough dietary carbohydrates and fat calories, the body will break down not only dietary protein but protein in the blood, liver, pancreas, muscles, and other tissues in order to assert vital organs and functions.

With regard to carbohydrates after training reconsider the following. Our bodies can only dispell monosaccharides (glucose, galactose, or fructose), the particular units of sugars and starches. Once absorbed straight through the small intestines into the portal vein, and then circulated into the bloodstream straight through the liver as blood glucose, our bodies can put glucose to work in three ways:

1. It can burn the glucose immediately for vigor if blood glucose levels are not at a stable level of 20 grams blood borne glucose circulating per hour.

2. If it is not needed for vigor immediately, then it is converted into glycogen in the liver or muscles. The liver has the capacity to store 100 grams of glycogen. The muscles have the capacity to store between 250-400 grams of glycogen, depending on muscle mass and bodily condition. Liver glycogen supplies vigor for the whole body. Muscle glycogen only supplies vigor to muscles.

3. If the body has an excess of glucose, and all of the glycogen shop are full, the surplus glucose is converted to fat by the liver and stored as adipose tissue (body fat) around the body. If needed, fatty acids can be burned as fuel (But the fat cannot be converted back to glucose).

Now that you have a best idea of what goes on in your body and how your body uses its resources for energy, you may now be able to understand how you can acquire more vigor with the straightforward use of "food" and not some incommunicable magical method.

Just keep in mind that it takes all three macronutrients (carbohydrates, protein and fat) in the proper amounts to keep vigor levels at there best. Always be sure to take in some carbohydrates and protein an hour before rehearsal and some more thirty minutes after, taking in your fats well before and well after exercise.
