The mechanism of transformation of food in energy depends on several factors. Knowing main principles of this mechanism, it is potential to find out to distribute load and properly to eat that will help to boost sports results considerably. The sports dietology is made on understanding of how nutrients — fats, proteins and carbohydrates — will be reworked into energy, that is important for a body for fulfillment of physical exercises. These substances in an organism turn to energy in a quite adenosine triphosphate. The energy necessary for work of muscles, an organism takes from split adenosine triphosphate. But of these 3 nutrients have the own mechanism of transformation in adenosine triphosphate. Carbohydrates are a basic energy source for fulfillment of intensive exercises. Fats, on the contrary, guarantee organism with energy for long, however not intensive exercises. Proteins do not provide an organism with energy. They essentially are used as a construction material for fabrics. Power exchange in an organism. The organism cannot accumulate adenosine triphosphate (accumulated adenosine triphosphate is used by an organism among many seconds), thus during physical activities the organism should create adenosine triphosphate constantly. There are 2 basic ways of transformation of nutrients in adenosine triphosphate by the organism: an aerobic metabolism (with oxygen) and anaerobic metabolism (without oxygen). Adenosine triphosphate into phosphocreatine is anaerobic manner of metabolism. Adenosine triphosphate – phosphocreatine is the metabolism way (typically named phosphatic system) ensures an organism with energy within ten seconds, and is employed for short-term intensive masses, like, as an example, hundred-meter sprint. During this case oxygen is not necessary for organism for production of adenosine triphosphate. At initial it uses all adenosine triphosphate, accumulated in muscles (inside 2-three seconds), then starts to use phosphocreatine for adenosine triphosphate synthesis. When the stock of phosphocreatine runs out (it occurs in 6-8 seconds), the organism passes once more to adenosine triphosphate synthesis in aerobic or anaerobic way. Anaerobic metabolism — glycolysis. The anaerobic metabolism, or glycolysis, synthesizes adenosine triphosphate only from carbohydrates. A by-product of such metabolism is lactic acid. At glycolysis energy is allotted as a result of partial splitting of glucose, and oxygen for this purpose isn’t required. The anaerobic metabolism makes energy for brief-term, intensive physical activities, lasting less than several minutes. In some minutes the accumulated lactic acid reaches a sure limit, so-called lactate threshold, and therefore the person feels weariness, a pain and burning in muscles. Aerobic metabolism. The aerobic metabolism produces energy for long physical activities. For adenosine triphosphate synthesis from nutrients — proteins, fats and carbohydrates — is employed oxygen. This way is slower, than anaerobic, in it is involved the system of blood circulation, supplying operating muscles by oxygen at that time when occurs adenosine triphosphate synthesis. The aerobic metabolism primarily is used throughout long physical activities of little intensity. Throughout trainings aerobic and anaerobic metabolism replace one another. In the training beginning, adenosine triphosphate is created beneath the scheme of anaerobic metabolism. As breath and pulse become frequent, organism gets a lot of oxygen, and therefore the organism passes to aerobic kind of a metabolism. Below this theme the organism continues to figure till will reach lactate threshold. When this limit is reached, oxygen will not arrive in an organism quickly enough for adenosine triphosphate synthesis, therefore again “joins” anaerobic metabolism. But this mechanism is taken into account for the short period of your time; thus it is necessary for sportsman to reduce intensity of exercise to stop formation of lactic acid.
