Staying fit during pregnancy, keeping mom & baby’s safety first!
Over 50 randomized controlled studies have been done to analyze the outcomes of exercise during pregnancy and the research supports exercising throughout pregnancy, citing reductions in health risks for mother and baby. *Please note that the research cited here involved mothers with uncomplicated pregnancies, carrying a single child. Overall, they found that women who exercised during pregnancy had a lower incidence of excessive gestational weight gain, gestational diabetes, preterm birth, gestational high blood pressure disorders, low birth weight and a higher incidence of vaginal delivery rather than cesarean delivery.
The randomized control trials that found exercise to be safe & beneficial during pregnancy recommend:
With these exercises, intensity may vary. The American College of Obstetrics and Gynecology recommends that pregnant women keep exercise at a moderate intensity. In order to avoid overexertion, pregnant women should be able to carry on a conversation during activity. Heart rate can also be tracked to monitor exercise intensity. Research suggests it is safe to stay below 60-80% of maximum maternal heart rate. (Maximum Heart Rate = 220 - age)
During pregnancy the female body adapts to a shifting center of mass as the baby grows, hormones fluctuate and cause systemic changes in ligamentous laxity to allow for delivery, and temperature regulation may be impacted by fetal development and different allocation of resources. A change in center of gravity may alter her balance, so it is important to be mindful during activities that can put her at risk of falls. Ligamentous laxity occurs at the pelvis to aid in delivery, but the hormonal shift can also loosen other joints in the body. Exercises and stretches should stay within normal limits of range of motion to avoid strain at extra mobile areas. Temperature regulation is an important piece of exercise/activity tolerance, so the exercising pregnant woman should take adequate rest breaks and maintain good hydration before, during and after activity to maintain healthy body temperature for herself and baby.
It is important to note that exercise should be tailored to fit each individual woman, taking into consideration her health, fitness level, stage of pregnancy, and goals. If possible, exercise should be prescribed and/or supervised by a professional with experience working with pregnant women.
The American College of Obstetrics and Gynecology does list a few conditions that put a hard stop on exercising during pregnancy, including:
The American College of Obstetrics and Gynecology also has some red flags that can present during exercise, if experiencing these symptoms, terminate exercise and seek medical attention:
