1, stimulate the stomach: Exercise after a full meal will bring mechanical stimulation to the stomach, which will make the dissolved substances in the stomach vibrate left and right, which will easily cause vomiting, stomach cramps and other symptoms.
2, affecting the effect of weight loss exercise: after eating, the sympathetic nerves in the body are easily suppressed, and if the body wants to exercise, the exercise effect will be greatly reduced.
3, blood flow distribution disorder: after eating a full meal, the digestive organs need a lot of blood for digestion and absorption, and the whole body muscles also need a lot of blood to participate in exercise, so it will seize the blood capacity of the digestive organs, leading to digestive and absorption dysfunction, not only affecting the exercise effect, but also causing harm to the body.
The best exercise time after meals is light exercise, such as walking and square dancing, and half an hour after meals is the most reasonable. Moderate exercise should be arranged one hour after meals, such as jogging and doing exercises. Two hours after dinner, you can do high-intensity exercise, such as running fast and going to the gym to do aerobic exercise.
For example, in the morning, if the exercise intensity is not properly controlled, it is easy to cause hypoglycemia. Afternoon sports are influenced by objective factors such as work, work and housework.
Modern sports physiology research shows that the highest and lowest points of human physical strength are controlled by the "biological clock" of the human body and generally reach the peak in the evening.
For example, the metabolic rate of the human body will peak at 4 pm to 5 pm, and the flexibility and flexibility of the body will reach the best state; Heart beating and blood pressure regulation are most balanced between 5 pm and 6 pm, while the body's sense of smell, touch and vision are also most sensitive between 5 pm and 7 pm. So, on the whole, the effect of exercise at night is better.
In addition, the hormone activity of the human body is also in a good state between 4 pm and 7 pm, and the body's adaptability and nerve sensitivity are also the best. Therefore, experts advocate evening exercise, but in the evening time, we should pay attention to the intensity of exercise, otherwise too high intensity will excite sympathetic nerves and hinder sleep.
