Sports drinks are used as a source of carbohydrates and are used for the flow of energy to exercise and to maintain the level of water in the body during the process of training. Unfortunately, with the fashion for healthy living manufacturers of sports nutrition grabbed the bull by the horns, and now on the market, there are a lot of products that, in some way, I promise you the energy flux. The only pity is that people blindly spend money on something that simply do not know: it is often these “magical elixir” is highly concentrated caffeine, which is the cause of heart disease and cardiovascular disease. But this is a separate issue.
There are three types of drinks that contain different amounts of water, electrolytes and carbohydrates. 6-8% isotonic electrolyte, water and carbohydrates. Hypotensive 6% electrolyte, 2% carbohydrate and 92% water. Hypertensive 32% carbohydrate, 4% of the electrolyte (sometimes excluded), and water.
Osmolality is a measure of the liquid components of the drink. In sports drinks, these ingredients: carbohydrate, electrolyte, sweeteners and preservatives. In blood plasma components are sodium, protein and glucose. Blood concentration is about 280-330mOsm/kg. Drinks with a similar concentration to balance the body’s internal environment. These are called isotonic drinks. Hypotensive have a slightly different concentration of these substances, and some other parts of the hypertensive. Fluid intake of low concentration (like water) lowers the plasma concentration and quenches thirst until both made up for all the lost material.
