What effect does drinking have on fitness?

　　Don't drink alcohol before exercise, as alcohol can dull your exercise skills and judgment, and can reduce strength, speed, muscular endurance, and cardiovascular endurance. A large amount of drinking at one time will lead to a decrease in reaction, balance and coordination. Even on the second day of moderate drinking, these motor abilities still cannot be fully restored. However, few people know that drinking a small amount of alcohol after exercise can relieve fatigue.

    Foreign medical research reports suggest that moderate drinking can dilate arteries and lower blood pressure, which is beneficial to patients with mild hypertension and poor blood circulation. Grape Alcohol can increase beneficial high-density lipoproteins and reduce harmful low-density lipoproteins, preventing heart attacks. Drinking some wine after exercise can relieve fatigue, because a large amount of lactic acid is produced after exercise, leading to an acid-base imbalance in the human body. Drinking alcohol can dilate blood vessels and accelerate lactic acid metabolism.

　　It should be noted that drinking after exercise should follow the principles of "timely", "moderate" and "appropriate amount". “"Timely" means you cannot stop exercising and drink alcohol immediately, especially drinking a lot of beer, because this will increase the burden on the heart and kidneys and cause damage. healthy , should be chosen when eating: "moderate" means that the alcohol content after exercise should be low-alcohol wine, such as wine, rice wine, beer, etc., and my country's traditional wine making such as Shaoxing wine and glutinous rice wine are also nourishing tonics that have been passed down since ancient times: "moderate" means that the amount of alcohol should be appropriate. Generally, liquor should not exceed 50 ml each time, and beer should not exceed 300 ml.

　　In addition, choosing the ideal side dishes when drinking can not only satisfy your appetite, but also supplement the missing nutrients after exercise. The best side dishes are foods that increase protein and contain many vitamins, such as fresh vegetables, fresh fish, lean meat, beans, eggs, etc.
