How long is it effective to drink red bull before exercise? Or glucose? Which is better?
As a sports drink, red bull is usually drunk two hours before exercise, which can increase the reserves of muscle glycogen and liver glycogen in the body.

Glucose is recommended to be drunk after exercise, because sugar and low-fat foods need to be supplemented at this time, and glucose is a good choice.

But you should also pay attention to drinking water at this time.

Here are some auxiliary materials, you can have a good look:

1. Sports drinks are the need of exercise.

Fluid replacement is an important part of exercise. During the intermission of sports competition or training, athletes often pick up a bottle of water and drink it with their heads up. Are they drinking boiled water? No, because boiling water will cause blood dilution, so that more water will be lost from sweat, which will easily cause electrolyte balance disorder in the body. So, are they drinking juice? Not exactly. Juice and juice drinks with relatively high concentration cannot be absorbed as soon as possible because of their high osmotic pressure. In fact, it is a new type of drink-sports drink.

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!

2. The principle of supplementing sports drinks during exercise

Supplementing 500 ml of liquid 2 hours before exercise can increase the reserves of muscle glycogen and liver glycogen in the body. Drinking more than a few times during exercise can prevent stomach discomfort, and supplementing 15~20 minutes with 125~250 ml of liquid can prolong exercise time and delay fatigue. Replenishing the fluid lost after exercise can accelerate the recovery of water, sugar, inorganic salts and trace elements lost in the body, promote the rapid recovery of muscle glycogen and achieve the effect of eliminating fatigue. The method is to add 1000 ml of liquid for every reduction of 1000 g body weight. Choosing sports drinks in fitness exercise can quickly replenish the liquid, energy and electrolyte lost due to sweating, and can effectively maintain or even further improve the state of the human body during or after exercise.
