It is a misunderstanding to exercise immediately after meals. According to folklore, it is because "exercise immediately after meals leads to gastroptosis".
The most common cause of gastroptosis is actually weakness of abdominal muscles and low abdominal pressure (that is, slim people), which is not directly related to whether they exercise after meals. Although some patients with severe gastroptosis may feel unwell immediately after meals, it is not exercise that causes gastroptosis. Scientific exercise can enhance the strength of core muscles to improve the condition.
In addition, another common saying is that "it is not advisable to exercise immediately after meals, because blood helps digestion in the stomach". This statement seems to be reliable, but it is actually a common misunderstanding. After eating, the blood flow of the digestive system does increase, but the human body has a strong reserve capacity. Friends who have donated blood may know that there is basically no discomfort when the acute blood loss is below 65,438+00%, and the body can quickly replenish and compensate, not to mention the increase of blood flow in the digestive system rather than blood loss after eating.
In fact, the human body has a strong adjustment ability, which can be dynamically adjusted at any time according to the needs of various organs of the body. Under normal circumstances, there is no need to worry about an organ ischemia. Moreover, the digestive process of the human body is not limited to 1 and 2 hours after meals. It takes 4 to 6 hours to empty the stomach, not to mention the time required for further digestion and absorption of the intestines. But no one will worry about having lunch at noon 12 and exercising at 4 pm will affect their digestion.
