Football players need to replenish body fluids and have enough inorganic salts after or during the game. So most of the drinks they drink contain some inorganic salts such as magnesium chloride, sodium chloride, potassium chloride and calcium lactate.
In the marathon, people sweat a lot. The main component of sweat is water, as well as minerals such as sodium, potassium, chlorine, magnesium, calcium and phosphorus.
Will drink sports drinks.
A certain sugar content
Sugar is the most economical and direct main energy substance of human body, which is stored in bone marrow, muscles and liver in the form of glycogen. Due to the limited sugar reserves in the body, if it is not replenished due to a large amount of consumption during exercise, the muscles will be weak and the exercise ability will decline. On the other hand, more than 90% of the brain's energy supply also comes from blood sugar. Lowering blood sugar will weaken the brain's ability to regulate exercise and cause fatigue. Therefore, sports drinks must contain certain functions. Better sports drinks are mainly oligosaccharides, which are beneficial to supplement blood sugar and make the brain and muscles absorb sugar continuously during exercise, thus improving endurance, prolonging fatigue and accelerating recovery after exercise. Oligosaccharide drinks are also beneficial to reduce blood lactic acid during exercise.
Level, increase muscle strength and work.
Proper amount of electrolyte
Excessive sweating will lead to a large loss of electrolytes such as potassium and sodium, causing physical fatigue and even cramps, leading to a decline in exercise ability. The sodium and potassium in the beverage not only contribute to the sodium and potassium lost in sweat, but also help to replenish the water retention in blood vessels and make the body get more water. The electrolyte content in the beverage is too low to achieve the supplementary effect; If it is too high, it will increase the osmotic pressure of the beverage, causing gastrointestinal discomfort, so that the water in the beverage can not be absorbed by the body as soon as possible.
Low osmotic pressure
In order to make the water and other nutrients in the beverage pass through the stomach as soon as possible and be fully absorbed, the osmotic pressure of the beverage is lower than that of the plasma, that is, the hypotonic beverage. The type and quantity of sugar and electrolyte in beverage are the direct determinants of osmotic pressure of beverage. Nutritional sports drinks can maintain low osmotic pressure even if they contain a variety of sugars and inorganic salts.
No carbonated gas, caffeine and alcohol.
Carbonated gas can cause flatulence and discomfort, and drinking a lot of carbonated drinks may cause stomach cramps and even vomiting. Caffeine and alcohol have certain diuretic and dehydration effects, which will further aggravate the loss of body fluids. In addition, they also stimulate the central nervous system, which is not conducive to the recovery of fatigue.
Some sports drinks have other additional ingredients, such as B vitamins, which can promote energy metabolism; Vitamin c can be used to scavenge free radicals, reduce their harm to the body and delay the occurrence of fatigue; Proper amount of taurine and inositol can promote the synthesis of protein, prevent protein from decomposing, regulate metabolism and accelerate the elimination of fatigue.
Because sports drinks have the above basic conditions, they can replenish water in time and maintain the normal balance of body fluids; Quickly replenish energy and maintain blood sugar stability; Replenish energy in time; Improve and improve the ability of metabolic regulation; Improve thermoregulation and cardiovascular function. So sports drinks not only quench thirst, but also disintegrate thirst!
