Exercise During Pregnancy - New Findings

Found this info recently....

In a large study of 90,000 births published in the American Journal of Epidemiology, it was found that any form of exercise during pregnancy reduces the risk of preterm birth. This was based on an extensive questionnaire given to pregnant women about their exercise habits. Even one hour a week of cardiovascular exercise was enough to decrease the risk of preterm birth almost 25% compared to sedentary women. And women who continued to exercise greater than 5 hours a week through their pregnancy continued to have a decreased risk.

Next, a team of researchers form Kansas City University has found that aerobic exercise during pregnancy improves fetal heart health and nervous system development. This is still preliminary non-published data announced at the American Physiological Society conference in New York last month.
