Pregnancy and Exercise

Exercise does a pregnant woman's body good and a new study supports its safety.

In the study, 45 pregnant women stepped onto treadmills in the name of science. Some of the women kept very active, others exercised regularly, and the rest didn't make a habit of exercising.

Each time they hit the treadmill, they spent 30 minutes moving at a moderate or vigorous space.

The researchers checked on the babies' health by measuring their heartbeat and the flow of blood through the women's umbilical cords.

The results showed that it's OK for active women to keep exercising at a vigorous pace while they're pregnant. Women who haven't been active should stick to a moderate pace during pregnancy.

Of course, pregnant women should talk to their doctor about how much exercise is safe for their particular situation. According to the American College of Obstetricians and Gynecologists, exercises that are well-suited for women during pregnancy include:

* Swimming

* Walking

* Aerobics

* And cycling

These experts remind you to drink plenty of water, and avoid activities that require lying on your back after the first trimester. Dizziness, shortness of breath, contractions, and vaginal bleeding or leakage are signs that you should stop exercising and contact your health care provider.
