It is not advisable to eat acidic foods such as fish after exercise. After exercise, sugar, fat and protein in the human body are decomposed in large quantities in the absence of endogenous oxygen, resulting in 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.
After exercise, you should eat more alkaline foods such as fruits, vegetables and bean products to keep the acid-base balance in the human body, so as to eliminate exercise fatigue and keep healthy.
You must have breakfast before exercise. You shouldn't exercise or eat too much on an empty stomach. Avoid indigestible food. It is best to eat a small amount of dairy products, cereals, fruits and drinks.
Physical exercise can improve the functions of respiratory system and blood circulation system, increase oxygen intake and blood output, and make nerve cells get more sufficient energy and oxygen supply, which is beneficial to the normal and efficient work of nervous system, especially brain, and has obvious effect on improving the intensity, balance and flexibility of nerve work process.
