It is better to exercise half an hour after a meal. People have their own hunger before eating, and if they exercise strenuously at this time, they will use the stored glycogen in their bodies, which will lead to hypoglycemia, dizziness, headache, hypoglycemia and other symptoms, and even cause hypoglycemic coma. In addition, after exercise, people will be more hungry, and it is easy to eat more food than usual.
Post-meal exercise is not timely, will affect the digestion and absorption function, resulting in gastric ptosis, acid reflux, gastric and duodenal ulcers and other symptoms, thereby jeopardizing human health. In addition, just after eating a large amount of blood in the body will be gathered to the gastrointestinal tract digestion, the body's other organs are relatively ischemic, at this time a large number of exercise, will increase the burden on the heart, but also lead to visceral ischemia.
So it is more appropriate to exercise half an hour after a meal, when the food in the gastrointestinal tract has been completely digested, and also to avoid hypoglycemia in fasting exercise. This period of time is not absolute, if the body's own digestive capacity is not strong, can be 1-2 hours after the meal and then exercise.
Precautions:
1, can not do strenuous exercise immediately after meals
If you do exercise immediately after eating, it can affect the absorption of the stomach and intestines, and often cause colitis, appendicitis, abdominal pain and other symptoms. At least one hour after eating to do exercise, this can reduce abdominal pain, gastroptosis and other gastrointestinal diseases.
2, after exercise need to rest for an hour to eat
Whether it is exercise before meals or after meals, should leave enough time, so that the stomach and intestines to get enough rest, to avoid excessive speed of intestinal peristalsis and affect the normal digestive function. Exercise only an hour or so after meals can digest the food in the stomach and intestines and reduce the burden on the stomach and intestines.
