But immediately after eating dizzy movement, this is actually very unscientific, the following we will look at what is the harm of exercise immediately after meals.

What are the hazards of exercising right after a meal

Exercise immediately after eating affects the blood supply of the digestive system

After a meal, a large amount of blood flows to the digestive system, especially the gastrointestinal organs, to ensure the supply of oxygen and nutrients needed for digestive work. If you exercise vigorously at this time, a lot of blood will flow to the organs of movement, especially the limbs to ensure that the muscles need to work, which will cause the digestive system blood supply is insufficient, the gastrointestinal can not get enough blood, gastrointestinal peristalsis will slow down and become weak.

Exercise immediately after eating causes disease

When the human body is exercising, sympathetic excitability increases and vagus nerve excitability decreases, so that the secretion of digestive juices is inhibited, which affects the digestion and absorption process, and if you often exercise vigorously after meals, it can seriously lead to stomach pain, indigestion, ulcers and other gastrointestinal and digestive diseases, and can also cause respiratory and cardiovascular diseases.

Abdominal pain caused by exercise immediately after a meal

Just after eating, the food in the stomach has not been digested clean, immediately exercise will make the mesentery connected to the gastrointestinal tract is strained, resulting in abdominal pain; exercise, most of the blood in the body transferred to the skeletal muscle, resulting in ischemia of the digestive tract, resulting in smooth muscle spasm of the gastrointestinal tract, resulting in abdominal pain; exercise when the whole body oxygen demand increases, the usual lack of exercise of people with small lung capacity, once the sudden strenuous exercise. Accelerated panting can easily lead to a reduction in negative thoracic pressure and obstruction of blood return to the liver, which leads to liver stasis and increased tension of the liver envelope and causes pain, specifically manifested as pain in the right upper abdomen.

How long is the best time to exercise after a meal

How long to exercise after a meal should be based on the meal time and the amount of food, as well as age, physical conditions and exercise intensity and other factors to decide, in general, the amount of food and carbohydrate-based, half an hour to an hour after eating can be carried out such as walking, walking, square dance, tai chi and other light exercise; an hour to an hour and a half after the meal, food slowly digested, can be carried out Jogging, weight loss exercises, cycling and other moderate exercise; but if you eat a high protein and fatty foods that are difficult to digest, it is best to exercise again after two to three hours.

Exercise after meals according to personal fitness decision

How long to rest after a meal before you can exercise, but also depends on personal fitness, and then according to the amount of diet and exercise programs and exercise, exercise intensity. In general, healthy and often exercise people, rest after meals for half an hour to an hour to carry out some moderate intensity of exercise; poor health, the body in a subhealthy state of the population, it is recommended to rest for a while and then exercise, forced exercise is not only no benefit, but also easy to harm health.

20 minutes after meals to take a walk is beneficial

Long-term ambulatory work, fat body type, too much stomach acid crowd, 20 minutes walk after meals, help promote gastrointestinal peristalsis, increase gastrointestinal fluid secretion, to help better digestion and absorption of food, but pay attention not to go too fast, not to go out immediately after eating, which is likely to lead to a reduction in the blood supply in the gastrointestinal, digestive enzyme secretion followed by a reduction in digestion.
