1 Eat a small amount of food before exercise. It is very bad for human health to start exercising on an empty stomach and just after eating. Eating a small amount of food half an hour before exercise can avoid digestive dysfunction caused by physical activity and enhance the exercise effect. If it is morning exercise, you must avoid indigestible food for breakfast, and it is best to eat a small amount of dairy products, cereals, fruits and drinks.

During exercise, you should replenish water in time. If the exercise time is less than 1 hour, drink 150 ml to 300 ml of water every15 minutes; If the exercise time is 1 to 3 hours, you should replenish sugar water to your body in time to avoid hypoglycemia. In addition, don't drink ice water during exercise, because drinking ice water during strenuous exercise will cause digestive system problems.
It is not advisable to eat acidic foods such as fish after exercise. After exercise, a lot of sugar, fat and protein in the human body are decomposed to produce acidic substances such as lactic acid and phosphoric acid, which will stimulate human tissues and organs and make people feel sore muscles and joints and mental fatigue. Fish and other foods are acidic foods. Eating these acidic foods after exercise will make body fluids more acidic, which is not conducive to the relief of muscle and joint pain and physical fatigue. Experts suggest that you should eat more alkaline foods such as fruits, vegetables and bean products after exercise to maintain the acid-base balance in the human body, thus eliminating exercise fatigue and keeping healthy.
