They are usually rich in carbohydrates-the most effective energy source. Sports drinks also contain electrolytes (chlorine, calcium, magnesium, sodium, potassium and other minerals), which will gradually decrease with sweat during exercise.
Sports drinks can properly replenish electrolytes lost during training, which is very important for delaying the occurrence of fatigue during exercise.
Let's start with the classification of sports drinks, which are mainly divided into four types: isotonic type, hypotonic type, hypertonic type and special functional type.
Isotonic drinks contain salt and sugar with a concentration similar to that of human body fluids, which can quickly replenish the liquid lost by sweating and provide carbohydrates.
This is the first choice for most athletes, including middle and long distance runners and team sports. Most sports drinks are moderately osmotic, and the sugar content of isotonic drinks is 5-8%, in which the proportion of soluble particles is close to that of human body, which can be quickly absorbed by human body to meet the needs of liquid, electrolyte and sugar.
Most drinks belong to isotonic drinks. Including Poukari Sweat, Gatorade, Unity of the Sea, Suntory Super Vitiligo Yellow Bottle, Rijiaman Lishui, Kuleshi Vitamin, Nongfu Spring Vitamin, Green Bottle Scream and so on.
The concentration of salt and sugar in hypotonic drinks is lower than that in human body. Suitable for daily activities, supplementing daily carbohydrate intake and muscle glycogen storage. It can be used in ultra-long-distance projects to meet the demand of high energy consumption, but it must be used with isotonic drinks to supplement the lost liquid.
