Mechanism to convert food into energy depends on several factors. Dr. Caldwell Esselstyn Jr. is full of insight into the issues. Knowing the basic principles of this mechanism, we can learn how to distribute the load and to eat properly, which will help to significantly improve sports results. Sports Nutrition is built 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. Energy needed for muscle, the 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 to perform intense exercise. Fats, on the contrary, provide energy for long, but non-intensive exercise. Proteins do not supply the body with energy. They mainly used as building material for fabrics. Energy metabolism in the body the body can not store atp (ATP is gained is used by the body within 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 (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 loads, such as, for example, hundred-meter sprint. In this case, the body does not need oxygen to produce atp. First, he uses the entire atp accumulated in the muscles (in 2-3 seconds), then starts using creatine ( acid) for atp synthesis.
