Running promotes physical fitness, boosts endurance, and enhances alertness. For pregnant women who maintained a running routine before conception, moderate-intensity running does not harm the fetus. This exercise is considered safe for them.

Pregnant women who continue exercising often experience less weight gain, lower obesity risk, easier deliveries, and quicker postpartum recovery. Appropriate physical activity also reduces the risk of gestational diabetes, preeclampsia, and cesarean sections, while improving mood. Maternal running further supports fetal brain development and decreases the risk of heart disease for the baby.

Pregnant women can still run at moderate distances and speeds, ensuring fetal safety. *Huong Ngan*

As pregnancy advances, an enlarging abdomen and shifting center of gravity can affect a mother's balance, increasing fall risk. Therefore, running on flat surfaces or using a treadmill is advisable. During pregnancy, the hormone relaxin loosens joints and ligaments in preparation for childbirth, heightening injury susceptibility. To prevent accidents, wear specialized shoes and bras, perform proper warm-ups and cool-downs, and prioritize good technique over speed. Staying hydrated and maintaining regular, moderate exercise will contribute to overall maternal health.

During the first three months of pregnancy, combining running with gentle outdoor walking is suitable. As the due date approaches, reduce exercise intensity or stop running to prevent imbalance and muscle strain. Should any unusual signs appear, such as: vaginal bleeding, leaking amniotic fluid, continuous uterine contractions, chest pain, dizziness, fainting, swollen legs, or shortness of breath, pregnant women must stop exercising and immediately seek medical attention at a hospital or healthcare facility.
