Do not drink beer as a drink in summer

Alcohol is considered to increase exercise capacity and is used in sports. For example, marathon runners are given brandy during the game. Even today, there are still some athletes who believe that a small amount of alcohol can increase exercise capacity and be consumed during exercise. However, in fact, on the contrary, alcohol reduces athletes' athletic ability.

Studies have shown that alcohol can reduce strength, speed, muscle endurance, and cardiovascular endurance. A large amount of alcohol consumption can also lead to a decrease in response, balance, and coordination. Even on the second day of moderate alcohol consumption, these exercise capacities cannot be completely restored. .

Some athletes believe that beer can supplement the sugar and water consumed during exercise and can be used as a reserve of sugar and liquid before competition or training. So can beer really supply muscles with sugar? Let's take a look: A bottle of 360 ml of beer can provide 16 grams of sugar, which is about 5.6 grams less than a bottle of candy with a sugar content of 6%.

More importantly, the main source of heat in beer is alcohol rather than sugar. Despite the rapid absorption, the energy in alcohol is only metabolized in the liver and not in the muscles. The energy (energy food) required by the muscle is little or not from the burning of alcohol in the body. Therefore, beer does not supplement the energy consumed by muscle work.

On the other hand, alcohol in beer stimulates the kidneys to produce urine, accelerating the loss of water in the body and aggravating dehydration. Studies have shown that the body can lose 3% of body weight due to moisture loss within 4 hours after drinking. This is particularly detrimental to exercise, especially endurance sports, and increases the risk of heart disease during exercise.

If you drink beer immediately after exercise, it will delay rehydration or even increase dehydration. Therefore, beer cannot be used as a sports drink before, during and after exercise.
