Exercise should be considered as a medicine and it can have a tremendous influence on health
As with medications, it is difficult to know the recommended dosage, possible side effects and contraindications in order to achieve positive results.
Health is living in harmony with oneself and with our physical abilities which vary depending on the amount of time we dedicate to physical activity.
Professional athletes know the importance of nutrition to get the most out of their performance. They know that a nutritional plan should provide adequate amounts of amino acids to improve muscle tone in step with the intensity and frequency of their workouts. When an athlete has given all his strength in a race he begin consuming his glucose reserves to make energy. If he kept running, the liver would be activated to make new sugar transforming the amino acids at its disposal. The longer the effort to continue, the greater the consumption of amino acids.
So, it is not enough to have efficient muscles, your liver must also be capable of maintaining constant glucose to contract the muscles and make better use of oxygen. Intense training 1-3 times a week while fasting is a great way to train the liver into converting amino acids into glucose and increase the wealth of enzymes that activate this pathway. But, if amino acids were deficient, your body would eat your muscles in an effort to maintain blood sugar levels (glycaemia).
The amino acids come into cells in concentrated gradients, so if concentrations are high in the blood, the muscles will have access to many amino acids.
The more you exercise the greater the consumption of amino acids for energy, so the basic need increases in order to prevent athlete’s body from eating their muscles!
It is difficult to pursue a balanced diet of carbohydrates and lipids while introducing at the same time sufficient quantities of amino acids with the consumption of food proteins. Dietary proteins contain a small percentage of the 5 essential amino acids which cover 75% of human nitrogen needs, a percentage that is almost always below 16%, and therefore either the athlete introduces a lot of calories (and excess nitrogen) or they will never meet their required need of essential amino acids.
The peak concentrations of amino acids control the synthesis of proteins and therefore a higher daily intake is advantageous for athletes. With the amino acids used as a supplement this is possible, for ease of intake and for the very low intrinsic calorie.
Supplementation with mixtures of essential amino acids, tailored on human needs, can keep a biological environment (a balance in the blood) suitable for protein synthesis and this is based on scientific evidence (Kraemer et al 2006).
Prolonged and repeated muscle contraction also require potassium, calcium and magnesium to ward off the risk of cramps, while zinc serves to keep intact the metabolism of collagen and the integrity of tendons and ligaments.
