Prenatal exercise and swimming benefits for maternal health

Physical activity during pregnancy offers significant health benefits for both mothers and infants. Research from the Universidad Politécnica de Madrid and the Universidad de Granada indicates that moderate training programs—specifically 55-minute sessions combining aerobic exercise and stretching three times a week—can reduce the risk of fetal macrosomia by half. Such activity can also decrease the likelihood of cesarean sections by 21% and instrumental births by 16%, while potentially shortening the first stage of labor by an average of 62 minutes.

Swimming is highlighted as a particularly effective aquatic exercise. According to Hospital Sant Joan de Déu, the buoyancy of water helps alleviate the weight gained during pregnancy, reducing pressure on the back and legs. Swimming improves cardiorespiratory health, increases muscle tone, and helps prevent circulatory edema. Additionally, the horizontal position used in swimming allows for better weight distribution and provides a cooling alternative during high temperatures, which can be hazardous for pregnant women.
