Endurance sports are like music concerts. Start in a low tone, where a steady rhythm and culminate into a crescendo that captivates the viewer and the athlete. And not unlike an orchestra, demands a flawless performance from every organ resistance, testing the limits of their resilience. Like any system, made by human will, take a pace bordering on fatigue, the athlete begins to hear music from the heart. What is often neglected, and considered unnecessary, in endurance sports is a high protein diet can increase aerobic capacity and strength performance.To support the effort and delay fatigue, the body needs an adequate supply of oxygen and fuel without accumulating waste, acids or heat. Greater the intensity of training, the greater the efficiency required. The capacity of the cardiovascular and respiratory systems, fuel depots in muscle, liver and renal systems must all expand exponentially out in endurance sports. If any of these conditions are not met, the internal environment uncomfortable. Metabolism slows, so the elimination of wastes, acids and heat and fatigue in stress of aerobic endurance sports provides the necessary stimulus for growth and development. The body is ready to build. All you need are the building blocks-the Proteins.Given adequate and timely supply of proteins, the body remains in a state of positive nitrogen balance. Eating enough protein, along with a high energy diet also influences the metabolism of carbohydrates and fats. In the well fed state, with sufficient physical activity, dietary proteins stimulate the simultaneous release of growth hormone and insulin. The combination of hormonal influence carbohydrate in the diet and diversions of fat in the aerobic muscle fibers where they are stored as fuel for strenuous exercise. The resulting increase in muscle stores of glycogen and lipid allows sustained activity for a long time. With enough proteins, the lean body mass, increasing endurance and performance during training and program.Proteins amino acids also directly supply between 1 and 6% of energy needs during training. The share of energy from proteins increases with exercise intensity. Given their role in bodybuilding, proteins are too important to be used as fuel and should try to minimize this percentage. Studies by Bowtell and Tarnopolsky, report that a high-energy (carbohydrate), diet, combined with high intakes of protein and moisture, has a protein sparing effect under aerobic conditions. However, when protein intake is insufficient, the high protein diet of energy does not protect against fuel use. Therefore, endurance athletes need a high level of protein intake not only to supply amino acids for growth, but also to ensure that amino acids are burned fuel.Endurance athletes need proteins but they need protein supplements? The answer, until recently, was negative for recreational and modest athletes. Protein supplements are recommended only for professional athletes and for athletes with dietary deficiency of the protein. However, these recommendations, based on a parameter called 'nitrogen balance, have often questioned. Young and Bier propose that there is a subtle state of protein deficiency, called the "state of accommodation, where an inadequate intake protein is masked by the breakdown of body proteins. Measurements based on nitrogen balance do not have the maintenance of accommodation and therefore not accurate enough to calculate protein needs. Mark Tarnopolsky, a recent review on protein requirements of endurance athletes, it also raises questions.Epidemiological similar studies, by McKenzie and others, including the amount of protein up to 20% of athletes may be below the levels recommended for sedentary people. So there is always the ambiguous quality and damping of a protein in the diet. Just eat protein in the diet is not guarantee that all essential amino acids in sufficient quantities. Given the central role of proteins in metabolic and physiological response to stress aerobic endurance sports, and uncertainties related to the intake of protein, a protein supplement such as Profect, a long way to go in improving education
