What is an isotonic and what is it for?
Although sweating is a way to maintain a normal internal body temperature (the body cools down), sweat leaches out a large amount of important minerals and dehydration can occur. Isotonic drinks allow you to quickly restore the loss of elements, which prevents some injuries and weakness as a result of training.What is an isotonic
Sports drinks are divided into three types, depending on how many carbohydrates they contain:
* Isotonic
* Hypotonic
* Hypertensive
Isotonic drinks contain from 6% to 8% carbohydrates, including glucose – the most necessary source of energy for your body. The amount and balance of particles of useful substances in isotonics is about the same as in the human body, and that is why many athletes prefer this drink.
Electrolytes
Electrolytes are the most basic minerals that help regulate the acid-base balance of sodium, calcium, potassium, magnesium, chloride, bicarbonate, phosphate and sulfate in the cells of the body. If you compare drinks with caffeine, low-sodium mineral water with an isotonic supplement and isotonic, then it is isotonic that will provide the best supply of minerals to your body.
Glucose
Carbohydrate glycogen, which becomes glucose and is stored in the muscles and liver, requires less oxygen to burn and produce energy than protein or fat. A standard athlete has 90 g of glycogen in the liver, and 400 g in the muscles. During an intense workout, carbohydrate reserves can be depleted at a rate of 3-4 g per minute, and this will completely empty the glycogen reserves in the body in about 2 hours of training. And to restore the spent glycogen reserves, the body will need from 24 to 48 hours, but the isotonic will help significantly speed up the process.
Water balance
It is logical that during heavy sweating it is necessary to consume a sufficient amount of liquid, but it is possible that water will cause a simple bloating – it does not contain enough glycogen and electrolytes. The more carbohydrates there are in a drink, the slower they will be absorbed and empty the stomach. Isotonic is absorbed about as quickly as water, but contributes to the retention of fluid during training, preventing dehydration.
Endurance
Isotonic drinks will allow athletes to make high-intensity training longer.
Conclusion
Isotonic is a very useful drink for athletes, which controls internal processes, such as the assimilation and withdrawal of water in the body, the balance of substances and the replenishment of glycogen reserves to increase energy. Isotonic has clear advantages over water during training, so if you want to make your workout more effective and longer, you should think about adding isotonic to your sports nutrition. However, it is necessary to consult a doctor before starting the use of supplements that work with the internal processes of the body.
