The positive impact of prenatal exercise

The following is a re-post of my August 2008 post Wanna Improve Your Odds?:

I mentioned back in April that I had been skimming the book Exercising Through Your Pregnancy, by James F. Clapp M.D. I was really impressed at that time with the amazing benefits of exercising through pregnancy. But I didn't read the book in-depth. I decided earlier this week that I wanted to take a closer look. Now that I've read several of the chapters and examined the data thoroughly, I am telling you... it absolutely blows me away.

There are risks inherent in pregnancy and childbirth, but we can do things to minimize those risks. We all know that good nutrition is essential for pregnant women. Poor nutrition often leads to pre-term and low-birthweight infants as well as pre-eclampsia in mothers. Eating well is one of the absolute best things you can do for your unborn child's physical and neurological growth. But now I'm convinced that exercise may be just as important.

I won't go into all the benefits of prenatal exercise here. I'd just like to focus on one set of benefits in particular--the effects of exercise on the course of labor. You might remember my very early post about the benefits of doulas. Having a doula assist your labor and delivery reduces many chidbirth risks significantly. Prenatal exercise has even more pronounced benefits.

Women who continue exercising regularly through the end of their pregnancies (three times a week for at least 20 minutes at a moderately hard to hard level of exertion) demonstrated the following reduced risks during the birth process...

* 35% decrease in the need for pain relief
* 75% decrease in the incidence of maternal exhaustion
* 50% decrease in the need to artificially rupture membranes
* 50% decrease in the need to induce or augment labor with pitocin
* 50% decrease in the need to intervene because of abnormalities in the fetal heart rate
* 55% decrease in the need for episiotomy
* 75% decrease in the need for operative intervention (forceps or cesarean section)

In addition, check these out...

* More than 65% of the exercising women delivered in less than four hours.
* 72% delivered before their due date (but fewer of them delivered before 37 weeks--preterm--than the control group). The exercising women delivered, on average, 5-7 days earlier than active women who did not exercise regularly.
* Significant reduction in the incidence of umbilical cord entanglement.
* Much lower incidence of fetus passing meconium from distress.
* Umbilical cord blood samples indicated that babies of exercising moms remained relatively stress-free with plenty of oxygen. They seemed to tolerate the stresses of labor and delivery better than the control group.
* The exercising mothers' infants were, on average, 14 oz lighter but overall growth was not compromised.
* Placentas of exercising mothers are larger, more efficient, and healthier-looking.
* Infants born to exercising mothers were more alert postpartum and needed less consolation from others.

(All of these results are taken from Dr. Clapp's studies as reported in Exercising Through Your Pregnancy. See this fabulous book for even more amazing benefits.)

It blows my mind.

Imagine how huge the risk reductions would be if you exercised through pregnancy AND had a doula. Whoah. We can do so much to avoid the pitfalls of pregnancy and birth. It gives me so much joy and hope to know that I am not at the mercy of chance. I have a great deal of power over my circumstances when it comes to pregnancy and birth. It is a wonderful thing to be able to choose to pro-actively reduce risks and bring so much benefit to myself and my babies. I love it!
