Safe Exercise During Pregnancy: Understanding and Managing Your Heart Rate

Are you pregnant and wondering about the ideal heart rate during exercises?

Here's a straightforward guide to help you exercise safely during this transformative period.

Understanding Heart Rate Changes in Pregnancy

During pregnancy, your heart works harder, pumping more blood to support your growing baby. This increase in blood volume naturally raises your heart rate. Depending on your trimester, you might notice your heart rate going up by 3-20%.

Monitoring Your Heart Health

Regular check-ups with your doctor or midwife are crucial. They will keep an eye on your heart health, ensuring everything is on track.

Personalising Your Safe Heart Rate

There's no universal 'safe' heart rate for pregnant women. It's important to listen to your body. A useful tool is the Borg Rating of Perceived Exertion (RPE) scale. It ranges from 6 (no exertion) to 20 (maximal exertion). A safe exercise level during pregnancy is typically between 12 to 14 on this scale, meaning the effort feels "somewhat hard."

Focusing on Exercise Intensity

Instead of obsessing over numbers, pay attention to the intensity of your workouts. The "Talk Test" is a simple yet effective method. If you can maintain a conversation while exercising, you're likely in a safe range. However, if you're too breathless to speak, it's a sign to dial back the intensity.

Continuing Regular Workouts

Continue your usual exercise routines, and adjust the intensity as your pregnancy advances. Remember, it's about maintaining fitness, not setting new records!

What if you were not exercising before getting pregnant?

Well, this is the perfect time to start! Starting moderate exercise (50% to 75% max Vo2) during pregnancy it's highly beneficial for both you and your baby, and here is why:

1) Fetoplacental Growth: Moderate exercise boosts the growth rate of the fetoplacenta, leading to a healthier placenta and a larger, leaner newborn.

2) Lower Gestational Diabetes Risk: Regular physical activity can slash the risk of gestational diabetes by up to 36%.

Avoiding Overheating

Overheating can pose risks to your developing baby. Exercise in a well-ventilated area, stay hydrated, and wear breathable clothes to keep your body temperature in check.

Watching for Warning Signs

If you experience any discomfort, sharp pain, contractions, frequent dizziness, vaginal bleeding, or any other concerning symptoms, don't hesitate to seek medical advice immediately.

Pregnancy doesn't mean putting your active lifestyle on hold, but it does mean being more mindful of your body's cues.

Stay healthy, stay active, and embrace the beautiful journey of motherhood!
