Glucose is a monosaccharide, which can be directly absorbed and utilized by the human body and is the main source of nutrients and energy. It can directly participate in the metabolic process in the body. In the digestive tract, glucose is absorbed more than any other monosaccharide, which can be directly used by human body and can effectively increase human energy and endurance.

2. After strenuous exercise, the human body consumes a lot of energy and does not replenish energy in time, which is prone to dizziness, nausea and other symptoms. Drinking glucose water in moderation helps to replenish energy. In addition, a lot of water is lost after exercise, and drinking glucose water in moderation can also replenish water.

3. Glucose is a monosaccharide, which can be directly absorbed by the body. Drinking glucose water after exercise can supplement the consumed glycogen. Add 30ml glucose to 150ml water, and drink it 30 minutes after exercise to supplement glycogen. Add 0.5g salt to glucose water to supplement electrolyte.

4. Glucose is a monosaccharide, which can be absorbed by the body quickly and does not need to be transformed by the digestive system again. Compared with other sugars, it eliminates the digestion step. Drinking glucose water after exercise can quickly replenish body energy, thus avoiding hypoglycemia after exercise.

Extended data:

1, glucose tolerance refers to the body's ability to regulate blood sugar concentration. After normal people eat rice and flour staple food or take glucose, it is almost completely absorbed by the intestine, which increases blood sugar, stimulates insulin secretion, increases hepatic glycogen synthesis, inhibits decomposition, reduces hepatic glycogen output and increases glucose utilization in the body. Therefore, the highest postprandial blood glucose does not exceed 10.0mmol/L, and the postprandial blood glucose remains in a relatively stable range. This shows that normal people have strong tolerance to glucose, that is, normal glucose tolerance. However, if insulin secretion is insufficient, it can exceed 7.8mmol/L 2 hours after oral administration of 75g glucose, which can be equal to or greater than11.1mmol/L, indicating that this person's glucose tolerance is reduced.

2. Grape glucose is widely used in clinic, which is used for the water and heat needed by patients with high fever, dehydration, coma or inability to eat. When a large number of body fluids are lost, such as vomiting and massive blood loss, 5% ~ 10% glucose and physiological saline can be infused intravenously to supplement water, salt and sugar for hypoglycemia and drug poisoning. Intravenous infusion of 25% ~ 50% hypertonic solution can dehydrate and diuretic tissues for a short time because of its hypertonic pressure. It can be used alternately with mannitol to treat brain edema and pulmonary edema and reduce intraocular pressure. Treatment of hypoglycemia by intravenous infusion of hypertonic glucose. Combined with insulin, it can promote the transfer of potassium to cells, and it is also one of the treatment measures for hyperkalemia.
