How long after a meal is it best to exercise?

When it comes to exercise, many people are familiar with it. When exercising, there must be a method to do it. Many people exercise casually. Casual exercise is not good for their own body, and it will cause various physical problems. This must be paid attention to when exercising. How long after a meal is the best time to exercise? Many people do not understand it. The following is a detailed introduction.

How long after a meal is the best time to exercise?

It is best to rest for a while after a meal. Generally, it is appropriate to run or do other physical exercises 1 to 2 hours later. However, for people who often participate in sports activities, you can rest for ten minutes to half an hour after a meal and then do other sports except strenuous activities.

Because the parasympathetic nerves that control the stomach are excited after a meal, most of the blood is concentrated in the stomach and liver. If you exercise right after a meal, firstly, the stomach that stores a lot of food will be jolted and will constantly pull the ligaments that fix the stomach. In the long run, this will cause the ligaments to loosen and lead to gastroptosis. Secondly, it will disperse the excitement points of blood and nerves, weaken gastric motility, and the food will enter the intestines without being fully ground, which is not conducive to further digestion and absorption.

Doing strenuous exercise immediately after a meal will inhibit the secretion of digestive juices and the peristalsis of the digestive tract. This is because during strenuous exercise, the blood flow to the muscles throughout the body increases, while the blood flow to the stomach and internal organs decreases relatively. These reasons can easily cause indigestion and malabsorption, affect metabolism, and even cause chronic stomach problems.

Running or exercising after a meal can sometimes cause abdominal pain, which may be caused by the following reasons:

1. After a meal, the stomach is full of food, and the gastrointestinal tract vibrates during exercise, causing the mesentery connecting the gastrointestinal tract to be stretched, causing abdominal pain.

2. During exercise, blood distribution shifts from the digestive tract to the skeletal muscles, causing ischemia in the digestive tract and leading to spasm of the gastrointestinal smooth muscles, thus causing abdominal pain.

3. During exercise, the body's oxygen demand increases. People who lack exercise usually have small lung capacity, so when they try to breathe hard, they are likely to have shallow and rapid breathing. This reduces the negative pressure in the chest cavity, causing obstruction of blood return to the liver, which leads to liver congestion and increased tension in the liver capsule, causing liver pain, which manifests as pain in the right upper abdomen.

After understanding how long it is best to exercise after a meal, don't be too anxious to exercise after a meal. Also, if you feel uncomfortable during exercise, you should stop exercising. This will cause more impact on your body. You should pay attention to this when exercising. At the same time, don't exercise for too long.
