When we are talking about sports drinks, most people drink this concept is not clear. Sports drinks, energy drinks, functional drinks, energy drinks, these sorts of labels dazzled us.
Sports drinks (Sports drinks), in fact, can be called rehydration drinks within the beverage containing carbohydrates (sugars) and salts, can supplement the material body in motion the loss. This comprehensive utility ratio from sports drinks carbohydrates, potassium, salt and sugar, in which the electrolyte can be more effective than water for the body to add moisture. Currently, the world's leading sports drink brands include Gatorade, Powerade, etc.
Although the human body electrolyte content and the ratio may change, but the main ingredient is fixed. The main ingredients are sodium, potassium, calcium, magnesium, chloride, bicarbonate, phosphate and sulfate. We sweat typically contains 0.02g per liter of calcium, 0.05g magnesium, 1.15g sodium, 0.23g and 1.48g potassium chloride, but this ratio will vary constitution.
Why are electrolytes for the body after exercise is very important? The reason is that if the intake of pure water without added electrolytes, then it may cause water intoxication - it is dangerous symptoms of an in vivo electrolyte imbalance caused. After intense exercise, dripping sweat will take away a lot of water and electrolytes in the body. If you just add a lot of water, then the concentration of the electrolyte will be lower than normal levels in the body, which may affect the central nervous system function. Many sports drinks and supplemented by a considerable body of electrolyte to avoid water intoxication. However, many of the electrolyte content of the beverage market are relatively low, so excessive drinking could still cause water intoxication.
Sports drinks can be divided into isotonic sports drinks, sports drinks hypertonic and hypotonic sports drink three, they difference is the concentration of the salt and sugar is higher than the average level of the human body. Most sports drinks on the market are moderate isotonic sports drink, per 250 ml of beverage contains about 13-19 grams of carbohydrates.
Sports drink is designed to help athletes rehydrate, especially when they are in training or competition. Electrolyte intake can effectively complement the loss of body water, which for practice or game delay fatigue is very important. As the muscles during exercise the main "fuel", a carbohydrate can also be effective to maintain the state of motion.
High-intensity training the body will break down muscle occurs, the body need to work to repair these muscles. As a result, each repair, our muscles have become stronger. Therefore, to provide the growth of our muscles adequate nutrition is essential. Dining after exercise should include protein and carbohydrates. The importance of protein to provide amino acids for the body repair muscles, carbohydrates provide insulin for the body, it helps the body amino acid intake.
However, sports drinks is not better, it depends on the intensity of exercise you do. ? British Paralympic sports nutrition expert Janet Crossland (Jeanette Crosland), said: "sports drinks for relatively high-intensity exercise beneficial, but if you are just half an hour to play badminton, and drink it, them. children should not become the order of the day.
