You’ve spent the last year or several years being fit, working out 3-5 times a week. Now you are pregnant and you have a few questions.
First we are going to discuss what you can and should do. Then we are going to get into some common mistakes made during fit pregnancies and pregnant athletes.
During pregnancy exercise helps swelling, varicose veins, back pain, etc. It provides benefits to the baby. But also know that Total Blood Volume in regularly exercising pregnant women is 10-15% higher than in women who do not exercise. And the benefits of cardio (aerobic exercise) are still present 6-12 months after birth. Which is why some athletes have improved performance after birth.
The following list of Do’s and Don’ts for fit pregnancies should be used in addition to the Pregnancy Exercise Guidelines.
You might feel frustrated by some of the limitations that pregnancy places on your agility. For example, weight gain and laxity in ligaments and joints reduce your running speed. The weight in pregnancy increases the force on your hips and knees. Your fine motor skills might feel sluggish, and you might try to compensate for your loss of dexterity by using her body in awkward ways, inviting injury as a result.
Overall don’t don’t get overtired, don’t continue if you feel lack of coordination or discomfort, don’t forget adequate fluid, and don’t forget a thorough cool down.
Pregnant women have the same exercise guidelines as non-pregnant women – aim for 20-30 minutes of moderate activity most days of the week. Keep reading on exercise sessions longer than 45 minutes, there are extra precautions. Exercise should not exceed pre-pregnancy levels. ACSM suggests that moderate to hard is quite safe for a woman who is accustomed to this level of exercise.
Overall, maintain a Rate of Perceived Exertion between 13-14, use the talk test or use a heart rate monitor (heart rate monitors are suggested for athletes only).
You can continue exercise such as running as long as you and your OB discuss and maintain a healthy pregnancy. Read the top 10 tips for running during pregnancy.
All exercise needs to be discussed with your OB.
Follow these additional guidelines according to your level of exercise.
Somewhat Active – When you are somewhat active (participating in exercise and activities a few times a week) 150 minutes a week of moderate intensity aerobic activity is encouraged. 20-30 minutes on most days is a good goal. In addition to aerobic activity, strength training should be done every other day.
Exercise Veteran or “Recreational Athlete” – When you habitually engage in exercise, you can and should continue your regimen, adjusted over time. Any session over 45 minutes can lead to low blood sugar, so limiting the exercise session or ingesting adequate caloric intake prior to exercise is important.
Athletes – can push their limits of pain and intensity. For example, a woman feels an RPE of 8 while doing intense exercise. But maybe as an athlete they have “turned off” their guide. Read more about what is too much here.
Overall, if you exercise 45 minutes or more you will want to follow these safety guidelines:
