Exercises suitable for pregnant women to control blood glucose are low- to moderate-intensity aerobic workouts, such as brisk walking, yoga and swimming. Exercise therapy can effectively control the weight of pregnant women, increase the blood supply to peripheral tissues, and improve the utilization rate of blood glucose in peripheral tissues, thus significantly improving the phenomenon of insulin resistance; exercise also improves cardiorespiratory function. The type of exercise should be decided according to the personal preference and physiological characteristics of pregnant women. Take low-intensity to moderate-intensity aerobic exercise as the main focus, try not to do strenuous exercise. Pregnant women can choose brisk walking, stair climbing, yoga, swimming and so on. Regardless of which type of exercise is performed, it is best to do it in 3 stages, including pre-exercise warm-up, formal exercise training, and post-exercise rest. The basic principle of exercise therapy is not to cause uterine contractions or distress to the fetus during exercise. Movements of the upper extremities generally do not cause uterine contractions, but movements of the lower extremities run the risk of causing uterine contractions. Pregnant women should avoid doing too strenuous exercise. Before exercising, pregnant women should go to the obstetrics and gynecology department for a thorough physical examination to rule out contraindications to exercise therapy (e.g., the risk of miscarriage, preterm labor, etc.), and to learn about precautions to be taken when exercising.
