So, why can't you do strenuous exercise after meals? This is because strenuous exercise after meals hinders the normal work of the digestive system, affects the digestion and absorption of nutrients, and is not conducive to the normal exercise. In exercise, the changes of various organs and systems of human body are very complicated, and it is necessary to coordinate and ensure the normal operation of various sports training under the unified command of the nervous system, the headquarters of human body.
After dinner, it should be the time for intensive work of digestive organs. If strenuous exercise is carried out at this time, the nervous system will use the main force to command and coordinate the muscle system, heart and lungs and other organs, and at the same time reduce the command to the digestive system, and the activity of the digestive system will be weakened, temporarily affecting the digestion and absorption of food. Any organ of the body will consume oxygen and nutrients when it is working. Oxygen and nutrients are supplied by blood circulation and blood transportation. After meals, a large amount of blood flows to the digestive system to supply oxygen and nutrients needed by digestive organs such as stomach and intestine to ensure timely digestion and absorption of the food eaten. If strenuous exercise is carried out at this time, the blood vessels in the digestive system contract, and a large amount of blood is transferred from the original digestive system to the muscles, and the blood supply to the digestive system is reduced, which weakens its activity ability and is unfavorable to digestion.
After a meal, strenuous exercise is also because the stomach is full of food. The heavily loaded stomach vibrates badly during exercise, and the fascia connecting the gastrointestinal tract is tight, which will cause abdominal pain. It is even worse to go swimming after a meal, because people in the water will be under the pressure of water and oppress the gastrointestinal tract full of food, which is not only bad for digestion, but also more prone to abdominal pain.
So how often can I go to exercise after meals? It depends on the nature, intensity and physical fitness of the physical exercise you take part in. Generally speaking, it is better for people who don't exercise regularly and who are weak to exercise for half an hour to an hour after meals. Intense competition activities, it is best to take place one and a half hours after meals.
It is not advisable to do strenuous exercise after meals, but it is not excluded to relax after meals. Everyone can do appropriate activities according to their own situation, such as walking, which not only does not hinder digestion, but also promotes digestion and health.
