Active participation in physical exercise is an effective way to enhance physical fitness. Why does it taste so good after physical exercise?

Active participation in physical exercise is an effective way to enhance physical fitness. The enhancement of physical fitness is a comprehensive manifestation of the improvement of the functions of various organs and systems of the human body. Through regular physical exercise, the appetite increases more and tastes particularly fragrant, reflecting the enhancement of digestive system function and the improvement of digestive ability.

The human digestive system is like a food processing factory. Its function is to digest and absorb nutrients. It is mainly composed of the digestive tract consisting of mouth, pharynx, esophagus, stomach, small intestine, large intestine and anus, and digestive glands such as salivary glands, liver and pancreas. The food we usually eat has to go through the complicated processing of digestive tract and digestive gland before it can become a nutrient that the human body can absorb and utilize.

During physical exercise, the metabolism is greatly strengthened than usual, and the body consumes a lot of nutrients. Someone has done experiments. During physical exercise, the metabolism is increased by 10 or even 20 times compared with that at rest. After physical exercise, the substances consumed in the body should be replenished in time, which is bound to absorb more substances from the outside, which will be processed by the digestive system and become substances in the body. Obviously, the workload of the digestive system is much larger than before. In this way, the function of the digestive system is improved day by day.

The activities of all human organs and systems are under the unified command and management of the nervous system. In the process of physical exercise, the nervous system strengthens the command of the motor organs and the heart and lungs, but reduces the management of the digestive system, so that the activities of the digestive system are relatively inhibited, so as to ensure the vigorous activities of muscles and the heart and lungs during exercise. After exercise, the nervous system strengthens the command of the digestive system, the activity of the digestive system is strengthened, and more nutrients are absorbed, thus improving the digestive ability.

During physical exercise, due to the deepening of breathing, the activities of diaphragm and abdominal muscles increase, the diaphragm moves up and down greatly, and the abdominal muscles move back and forth, which plays a massage role on the gastrointestinal tract. After the exercise, this massage will last for a period of time, thus promoting the activities of the stomach and intestines, and also having a good influence on the improvement of the digestive system function. This is why eating after physical exercise is particularly fragrant.
