Reason:
After a full meal, the gastrointestinal tract is full of food, and exercise immediately will inevitably involve the gastrointestinal tract due to gravity, which is prone to abdominal discomfort and abdominal pain, and even vomiting. Just after eating, the blood supply of the human body will be more distributed in the gastrointestinal tract to help complete the function of digestion and absorption. If you exercise vigorously at once, the blood supply takes precedence over the muscle tissue, which will inevitably affect the normal digestion and absorption.
In addition, the sympathetic nerve in the human body is excited during exercise, and the vagus nerve dominating the gastrointestinal tract will be inhibited, thus weakening the secretion of digestive juice and the peristalsis of the gastrointestinal tract. Therefore, exercise immediately after meals can lead to indigestion, and long-term exercise immediately after meals may lead to gastrointestinal dysfunction.

Expert advice:
If you have chronic gastrointestinal diseases, exercise immediately after eating may induce or aggravate the original gastrointestinal symptoms, so it is suggested that:
(1), light exercise within half an hour after meals is the most reasonable, such as walking and square dancing.
(2) Moderate exercise should be arranged one hour after meals, such as jogging and weight-loss exercises.
(3) High-intensity exercise can be carried out two hours after dinner, such as basketball match and football match.
