1, whether it is anaerobic exercise or aerobic exercise, there should be a gap between exercise and eating. Generally speaking, it is advisable to eat about 30 minutes after exercise, and it is better to exercise at least one hour after eating. If it is anaerobic exercise, it is recommended to extend the interval and take a rest before eating.

2, because just had a full meal, gastrointestinal activity increased, digestive juice secretion increased, and the amount of blood needed in the process of digesting food also increased. At this time, if strenuous exercise is carried out immediately, gastrointestinal activities and secretion of digestive juice will be inhibited due to the adjustment of nerves and body fluids, so that the blood supply of the gastrointestinal tract will be relatively reduced and more will be supplied to the exercise organs, which will lead to the weakening of gastrointestinal digestive function and easily cause gastrointestinal discomfort and pain, and even indigestion.

3. Similarly, you should eat regularly after exercise, because the center that manages muscle activity during exercise is in a state of high excitement, and at the same time, the digestive organs are inhibited, and the activities of the digestive organs will take some time to recover. Therefore, generally do not want to eat immediately after strenuous exercise for a long time, but rest for about 30 minutes before eating.
