Why do people get tired after exercise?

People feel muscle and joint pain and mental fatigue after fitness exercise. The main reason is that a large number of sugar, fat and protein in the body are decomposed, and acid substances such as lactic acid and phosphoric acid are produced in the process of decomposition. These acidic substances stimulate human tissues and organs, making people feel muscle and joint pain and mental fatigue.

At this time, if you simply eat meat, eggs, fish, etc. Rich in acidic substances will make body fluids more acidic, which is not conducive to the lifting of fatigue. Eating more fruits, such as vegetables, sweet potatoes, oranges and apples, can eliminate redundant common acids in the body, reduce the acidity of urine, increase the solubility of uric acid, and reduce the possibility of acid forming stones in the bladder.
