In which position should pregnant women avoid prolonged bouts of exercise?

1. Standing

2. Seated

3. Supine

4. On their side

The correct answer is: Supine

Prolonged bouts of exercise in the supine position, or lying on the back, are generally advised against for pregnant women, especially after the first trimester. This recommendation is based on the potential physiological changes that occur during pregnancy. When a woman lies supine, the weight of the growing uterus can compress major blood vessels, particularly the inferior vena cava, which can lead to reduced blood flow to the heart and, consequently, lower blood circulation to the fetus. This can cause dizziness and can disrupt the oxygen supply to the fetus, making it critical for pregnant women to adopt safe exercise positions. In contrast, standing, seated, or lying on the side positions are considered safer alternatives during pregnancy. These positions help maintain better circulation and ensure that both mother and fetus can receive adequate oxygen and nutrient supply during exercise. Therefore, avoiding prolonged exercise in the supine position is a key consideration for the safety and well-being of both the mother and the developing baby.
