Is it good to drink lots of water before exercise?

Water is the source of life. It is an indispensable resource in our lives. Some experts say that drinking 8 glasses of water a day is necessary to stay beautiful. Try to drink as little water as possible before meals. So, is it good to drink water before exercise? Will drinking water before exercise affect our exercise results? Will it make us feel uncomfortable during exercise? The editor also has this problem. The editor also likes to drink water before exercise. Let’s take a look at whether this habit is good or not.

We all know the importance of water to the body, especially for people who exercise. Maybe you also know that you should drink more water, but what kind of water should you drink when exercising? How much water should you drink? When should you drink it?

How much water do you lose during exercise?

Would you believe it? The amount of sweat you lose by doing aerobic dance for an hour is almost as much as that in a small bottle of mineral water.

The amount of sweat lost during exercise is mainly related to the exercise environment and intensity. The higher the intensity of the exercise and the worse the air flow in the exercise environment, the more sweat will be lost. Taking the exercises that most people do regularly, such as one hour of aerobic dance or low-to-medium-intensity jogging, as an example, they usually lose about 500cc of sweat after exercise. If they play basketball under the scorching sun or increase the intensity of exercise, the amount of water lost may be close to 1000cc.

In addition, when the body loses a large amount of water after exercise, the salt concentration in the blood will increase and increase the burden on cardiovascular function. Therefore, if it is not replenished in time, it will affect the operation of cardiovascular function.

Principles of hydration during exercise

Water replenishment should be divided into three stages: before, during and after exercise. Replenish about 500cc of water before exercise, replenish 100cc to 150cc of water intermittently every 10 to 15 minutes during exercise, and replenish as much as possible after exercise. Since it takes 20 to 30 minutes for water to be ingested, enter the gastrointestinal tract, and then be absorbed by the human body, drinking a large amount of water at one time will instead cause the water to concentrate in the stomach and fail to truly achieve the purpose of replenishing water.

As for the claim that drinking a large amount of water at once before exercise may lead to "gastroptosis", this may be an excessive worry; replenishing water in excess of the load before exercise may indeed cause a feeling of fullness and affect exercise performance, but it will not cause gastroptosis.

Are sports drinks really suitable for exercise?

As fitness becomes a habit for more and more people, the brands and advertised functions of sports drinks have become increasingly dazzling. However, are sports drinks really more suitable for athletes than boiled water? The key to replenishing water after exercise, in addition to the amount of water consumed, also includes the body's ability to retain water.

Professor Xu also said, "Because exercise will cause the human body to lose electrolytes such as sodium and potassium, the body is in an unbalanced state. At this time, the water you drink to replenish will often be directly excreted from the body, and cannot be well stored in the body for the body to use." Due to the loss of electrolytes, the body's pressure is unbalanced. At this time, in addition to replenishing water, it is also necessary to replenish appropriate electrolytes to help the body's pressure return to a balanced state and allow the intake of water to be retained in the body for the body to use.

To sum up, there are certain "rules" if you want to exercise and drink water at the same time. Everyone must pay attention to these little common sense in daily life and exercise. Avoid discomfort in life caused by drinking water at the wrong time and inappropriate amount. The editor also reminds everyone to pay attention to their daily eating habits. Only by paying attention to all aspects can you have a good body.
