Most of my friends have thought I am nuts for running so much when I wasn't pregnant. Running is a very odd sport, but it can be very addictive. I don't run to lose weight, to look a certain way, or because I have to. I run because I like the way I feel after a hard workout, I love pushing myself to my limits, and there is no better feeling than breaking a PR (personal record) or racing a new distance.
I am pretty sure most people would not be surprised to learn that I have kept running through my pregnancy. David sure wasn't surprised. I found out I was pregnant on a Sunday, the week prior I had run 60 miles and did 2 very intense interval workouts. I was close to being in the best shape of my life, having run my first marathon just a month before getting pregnant. I scheduled an appointment with my OB right away, and was able to talk with him quite a bit about my hopes to run through pregnancy. Because I had been running at a high level for a long time my doctor had no issue with me continuing to run. He was even okay with me continuing to do hard workouts, but for my own piece of mind I cut them out, or slowed them down a lot until I completely stopped doing them around 10 weeks.
I have set running goals for myself throughout my pregnancy thus far, but they are goals that are there to keep me from making excuses when I just want to be lazy. If I am not feeling well, or if there is something pregnancy-related that makes me feel like I should back off, those goals go out the window. Baby boy is number one, not my running goals. So far, I have met and exceeded all of my goals through 25 weeks. I am actually still surprised at how much I am running, and how normal it feels.
I read a great book called, "Exercising Through Your Pregnancy" by Dr. James Clapp. He did extensive research explaining the effects of regular exercise on all phases of pregnancy. After reading this book I really felt that if I am physically able to exercise I should, simply because of all the benefits to mom and baby. A few interesting points from his studies and research:
- Exercising women (EW) aren't any more likely to have preterm labor. They are more likely to deliver at full term (37-40wks) and less likely to deliver past 40wks. They tend to deliver 5-7 early than sedentary women (SW).
- EW don't have low birth weight babies but they do have more lighter babies and fewer big babies.
- Exercise doesn't slow the growth of the placenta, it actually grows almost a 1/3 faster in mid-preg has about 15 more vessels and surface area at term.
- There is a dec in the need for medical interventions for EW. 75% dec in incidence of maternal exhaustion; 50% dec in need to artificially rupture membranes; 50% dec in need to use pitocin to induce or stimulate labor.
- Babies of EW tolerated the stress of labor, measured by fetal heart rate, much better than those of SW.
- All measurements of growth and development after birth in babies of EW were equal to or better than those of SW
- EW gain less weight, deposit and retain less fat, feel better overall, and are more likely to return to pre-pregnancy weight within one year.
- When studied a year after birth, EW who maintain exercise after birth routinely increased their max aerobic capacity by 5-10%
There are tons more benefits that I could list, but that gives a good idea of some of them. I also don't mean to say that running while preggo has been all great. I have to stop a ton for bathroom breaks thanks to increased pressure on my bladder. My running clothes do not fit so well now, but it is way too expensive to by new stuff just for pregnancy so I am trying to make it work. With the increase in weight and shift in my center of gravity, my stride is changing which has caused my calf muscles to burn every single day while running for the last month. I have to now stop every 1 or 2 miles to stretch them in order to alleviate the burn. I get more stares than normal, especially when I run on the treadmill at the gym. I can't run outside right now in the snow because it is too dangerous given the likelihood of a fall, so it is boredom on the treadmill for the time being.
All those things aside, I am grateful that my body has allowed me to continue running, because I know there are many women who run even more than I do who are unable to continue in pregnancy. I hope to continue over the next 15 weeks, but I have to hold it loosely since it is not in my control! My doctor here in France and in the US are both supportive and aware of how much I run so I plan to continue to listen to my body and keep going! Maybe in May you will hear a story of how I ran the day I went into labor!
