Problem description:

Should I eat before aerobic exercise?

If you have a simple meal, how many mouthfuls do you eat to pad your stomach, or how long do you exercise after eating?

How about eating immediately after exercise?

Have a good appetite after eating. Do you want to control your appetite at this time?

Analysis:

It is not advisable to engage in strenuous exercise before and after meals, and there should be a certain interval between exercise and eating.

Due to the movement of muscles during exercise, the whole body blood is redistributed, and a large amount of blood flows to the muscles involved in exercise. The blood vessels of internal organs such as the stomach and intestines are in a state of relative contraction, so the digestive absorption function is also in a state of inhibition, the secretion of gastric juice is reduced, and the digestive ability is weakened. In addition, sympathetic nerve is excited during exercise, and adrenaline secretion is greatly increased, which can also weaken gastrointestinal peristalsis and greatly reduce digestive gland secretion. However, this state cannot be changed immediately after exercise. It takes a certain period of rest to return to normal, and you can't eat immediately after strenuous exercise. If you eat immediately after strenuous exercise, it will affect your digestion and absorption ability. In the long run, it will cause symptoms such as indigestion, loss of appetite and chronic gastritis. Generally speaking, it is more appropriate to rest for half an hour or even longer after exercise.

Similarly, you can't take part in strenuous exercise immediately after meals. If you take strenuous exercise immediately after a meal, the blood that is participating in gastrointestinal digestion will be redistributed and flow to organs such as muscles, which will also affect gastrointestinal digestion and absorption.

Take part in strenuous exercise immediately after a meal, and it will also cause abdominal pain and discomfort due to the vibration of the gastrointestinal tract and the involvement of mesentery, which is not conducive to health and exercise, so you can exercise at least one and a half hours after a meal.
