You can drink red bull, pulsating and screaming drinks before the sports meeting, but drinking sports drinks before the sports meeting is much better than energy drinks.

Sports drinks are far better than energy drinks, because sports drinks can help drive the body and help restore normal body functions. At present, the main sports beverage brands in the world include Gatorade and Powerade.

Sports drinks can actually be called rehydration drinks, which contain carbohydrates (sugars) and salts, and can supplement substances lost by the human body during exercise. This utility comes from the comprehensive ratio of carbohydrate, potassium, salt and sucrose in sports drinks, in which electrolyte can replenish water for human body more effectively than water.

Although the content and proportion of electrolyte in human body may change, its main components are fixed. These components are mainly sodium, potassium, calcium, magnesium, chloride, bicarbonate, phosphate and sulfate. Human body generally contains 1.12g of calcium, 1.15g of magnesium, 1.15g of sodium, 1.23g of potassium and 1.48g of chloride per liter of sweat, but this proportion will vary from person to person.

Sports drinks can be divided into three types: isotonic sports drinks, hypertonic sports drinks and hypotonic sports drinks. The difference between them lies in whether the concentration of salt and sugar is higher than the average level of human body. Most sports drinks on the market are mild isotonic sports drinks, and each 251ml drink contains about 13-19g of sugar.

Sports drinks are designed to help athletes replenish water, especially after training or competition. Intake of electrolyte can effectively replenish water lost by the body, which is very important for delaying fatigue in practice or competition. As the main "fuel" of muscles during exercise, carbohydrates can also effectively maintain the state of exercise.

High-intensity training will break down the muscles of the body, and the body needs to work hard to repair these muscles. As a result, muscles become stronger every time they are repaired. Therefore, it is necessary to provide adequate nutrition for muscle growth. Catering after exercise should include protein and sugar. The importance of protein lies in providing amino acids for human body to repair muscles. Sugar (also known as carbohydrate) can provide insulin for human body, which contributes to the intake of amino acids.
