ATP Metabolism

Mechanism to convert food into energy depends on several factors. Knowing the basic principles of this mechanism, we can learn to distribute the load and eat right, that will significantly improve sports results. Sports nutrition is based on an understanding of how nutrients – fats, proteins and carbohydrates – are converted into energy needed for body exercise. These substances in the body converted into energy in the form of adenosine triphosphate, or ATP. The energy required for muscle, your body takes from the split of adenosine triphosphate.

But each of these three nutrients in a conversion mechanism ATP. Carbohydrates – the main source of energy for intense exercise. Fats, on the contrary, provide energy for long, but intense exercise. Proteins do not supply the body with energy. They are used as building material for fabrics. Energy metabolism in organizme.Organizm can not accumulate ATP (ATP accumulated used by the body for a few seconds), so during physical activity the body has to constantly produce ATP. There are two basic ways to transform the body of nutrients into ATP: aerobic metabolism (with oxygen) and anaerobic metabolism (without oxygen). ATP-FC anaerobic pathway ATP-FC pathway (sometimes called a phosphate system) provides the body with energy for 10 seconds, and is used for short-term intensive workloads, such as, for example, hundred-meter sprint.

In this case, the body does not need oxygen to produce ATP. First, it uses the entire ATP accumulated in the muscles (2-3 seconds), then starts using creatine (kreatinfosfornuyu acid) for the synthesis of ATP. When the battery runs low creatine phosphate (it occurs in 6-8 seconds), the body goes back to the synthesis of ATP by aerobic or anaerobic. Anaerobic metabolism – glycolysis anaerobic metabolism, or glycolysis, ATP is synthesized only from carbohydrates. A byproduct of this metabolism is lactic acid. When glycolysis energy is released as a result of partial digestion of glucose, and it does not require oxygen.
