Staying active during pregnancy is the best thing for you – and your baby, Cindy Tilney tells us.
While exercise may not be what you feel like doing when you’re expecting, experts agree that it has a host of benefits – besides being a natural mood-lifter, there’s no denying how good it is for you. “In pregnancy, it’s always better to exercise than not – even with a chronic disease such as diabetes,” says personal trainer Shelley Lewin, who offers specialised pre- and postnatal exercises in Cape Town. “Staying active is not only important for the physical and emotional health of the expecting mother – research has shown that unborn babies thrive if their moms are active. Unless you have a specific medical condition that puts you and your unborn child at high risk during pregnancy, it can only work to your advantage,” she says. “And in people with diabetes, it can help the body to process glucose more effectively.”
What can exercise do for pregnant diabetics?*
- Lower blood sugar
- Improve insulin sensitivity
- Control blood pressure
- Increase energy
- Reduce after-meal blood sugar spikes
- Encourage restful sleep
- Lower gestational weight gain.
According to the American College of Obstetricians and Gynecologists (ACOG).
*Type 1, Type 2 and gestational diabetes
Remember: If you have diabetes, it is essential to get the all-clear from your doctor before starting an exercise programme, particularly if you are pregnant.
“Exercise in any form may require a reduced amount of insulin because exercise increases glucose uptake in the cells,” explains biokineticist Sarah Hall. “The intensity of the exercise you are doing will determine this: lower-intensity exercise can lead to a recommended insulin reduction of roughly 20%, as opposed to a possible 50% with higher intensity exercise.” This is further complicated by insulin needs often doubling during pregnancy, so consulting a doctor is a must.
Healthy exercise tips during pregnancy:
- Check your blood sugar before and after exercise (Type 1 diabetics).
- Always take a ‘quick-fix’ snack, such as a banana, along with you when you exercise, so that you have a sugar source on hand in case of hypoglycaemia (low blood sugar).
- Stay away from forms of exercise that carry a high risk of falling, and avoid lying on your back with the head below the level of the heart, as this can restrict the blood flow to your baby.
- Wear a heart rate monitor during cardiovascular exercise, and keep your heart rate to 140bpm or below. In the past, there was a widely held belief that pregnant women should stay away from all cardiovascular exercise – but modern research has shown that this does not hold true.
The good news? If you’ve been exercising regularly, you can carry on very much as normal, agree Hall and Lewin – provided the activities are not extremely high impact, do not involve fast or sharp changes in direction, or cause surges in blood pressure or adrenalin.
Ideal pregnancy exercise
Both experts recommend 30 minutes of moderate physical activity three times a week, such as walking, swimming, aqua aerobics and light weight lifting under the guidance of a certified ante-natal instructor. The ligaments tend to naturally relax during the second and third trimesters of pregnancy, so be careful not to overstretch during warm-ups – and if you are weight training, use machines rather than free weights to avoid any hyperextension injuries.
“Building up core strength is important in pregnancy,” says Lewin, “but as your tummy grows, you should stay away from certain intense core exercises, such as tummy crunches – instead opt for opposite leg and arm lifts, or practice stability work on a Pilates ball.” Kegel exercises are also important during pregnancy, as they strengthen the pelvic floor muscles.
Be gentle with yourself during pregnancy: stay away from contact sports and aggressive forms of exercise. And be aware of your body and how hard you are pushing yourself during workouts. “The ‘talk test’ is always a good marker of whether you are pushing yourself too hard,” says Lewin. “If you are exercising at the right level, you should be able to talk at the same time – but if you’re struggling to take in breath and unable to hold a conversation, it means you are pushing yourself too hard.”
