First of all, exercise should be avoided for a period of time after meals. Because after dinner sports meeting:
(1) Stimulation of stomach and intestines: exercise after a full meal will bring mechanical stimulation to the intestines and stomach, making the solutes in the intestines and stomach vibrate left and right, up and down, which may cause vomiting, stomach spasm and other symptoms.
(2) Blood flow distribution disorder: after eating a full meal, digestive organs need a large amount of blood for digestion and absorption. When the muscles of the whole body are moving, they also need a large amount of blood to participate, so they will seize the blood volume of digestive organs, leading to digestive and absorption dysfunction, which not only affects the exercise effect but also harms the body.
(3) Affect the exercise effect: the parasympathetic nerve in the body is easy to be inhibited after eating. At this time, if the body wants to exercise, the exercise effect will be discounted.
(4) After meals, insulin secretion increases, which can inhibit the decomposition of fat, and the source of energy is limited. Due to less fat decomposition, weight loss exercise should not be carried out in this period.
Research found that high
Intensity exercise can be carried out three hours after dinner; moderate exercise should be arranged in two hours after dinner; light exercise is the most reasonable one hour after dinner. On this basis, several optimal motion periods can be derived
Morning: 3 hours after breakfast to before lunch;
Afternoon: 3 hours after lunch to before dinner;
