Questions: According to the physical activity guidelines for pregnant women, exercise should include which of the following? weight-bearing exercise vigorous exercise extended exercise in the supine position mild to moderate exercise

The answer is: mild to moderate exercise.

Explanation for each option:

1. Weight-bearing exercise: While some weight-bearing exercises can be beneficial during pregnancy, they should be approached with caution and under the guidance of a healthcare provider. Not all weight-bearing exercises are recommended for all pregnant women, especially if they have certain medical conditions or complications.

2. Vigorous exercise: Vigorous exercise is generally not recommended for pregnant women unless they were already accustomed to such levels of activity before pregnancy and have received approval from their healthcare provider. The guidelines typically suggest avoiding high-intensity workouts to prevent undue stress on the body.

3. Extended exercise in the supine position: This is not recommended, especially after the first trimester. Lying flat on the back can cause the weight of the uterus to compress the vena cava, a major blood vessel, which can reduce blood flow to the heart and potentially cause dizziness, shortness of breath, and decreased blood flow to the fetus.

4. Mild to moderate exercise: This is the recommended level of physical activity for pregnant women. Activities such as walking, swimming, and prenatal yoga are generally safe and beneficial. Mild to moderate exercise can help maintain fitness, reduce stress, and prepare the body for labor and delivery.

In summary, the physical activity guidelines for pregnant women emphasize the importance of mild to moderate exercise to ensure both maternal and fetal health.
