«From the 38th week of pregnancy onwards, you should take things a little easier»

There are many rumours and myths surrounding exercise during pregnancy. In this interview, gynaecologist Dr. Susanne Baer Altorfer reveals what is recommended from a medical point of view.

In the past, gynaecologists advised against exercise during pregnancy. What is the situation today?

Dr Baer Altorfer: Today, things are definitely different: moderate exercise is generally recommended. Exercise is good for you, and that also applies during pregnancy. A young woman who is healthy and has always been physically active can continue to be active without any problems if she has a complication-free pregnancy.

What you should not do is start a completely new sport during this time and overexert yourself. Anyone who was not particularly athletic before pregnancy should definitely seek professional advice and instruction.

From a medical point of view, how long into pregnancy is exercise recommended?

Dr Baer Altorfer: If a woman is healthy and the pregnancy is proceeding without complications, moderate exercise can generally be continued until the birth. Ideally, you should take it a little easier from the 38th week of pregnancy onwards, because the strain on the cardiovascular system is very high during this phase.

From the 38th week of pregnancy onwards, and as soon as the body is ready, moderate exercise – such as walking down stairs – can support the natural process of labour.

Exercising during pregnancy

What is good for you and what isn't?

Two pelvic floor specialists from Rosenklinik Physiotherapie reveal which exercises and sports are beneficial and what you should pay attention to in order to get the most out of exercise for yourself and your baby.

What physical signs should pregnant women look out for that indicate they should stop exercising?

Dr. Baer Altorfer: Women usually know their bodies best. If they don't feel well, they shouldn't ‘force’ themselves to exercise, but rather slow down and listen to their bodies a little more than usual.

If you experience contractions or labour pains, bleeding, water breaking, abdominal pain or shortness of breath, you must stop exercising. In this case, be sure to consult a gynaecologist.

Pain in the musculoskeletal system, for example in the hips, knees or feet, should also not be ignored. Exercise during pregnancy is good, but it should not be an additional burden. This should not be underestimated.

What myths or misconceptions about exercise during pregnancy do you often encounter?

Dr Baer Altorfer: Probably the biggest myth is that exercise during pregnancy is harmful. In this context, people often worry that the baby will be shaken too much or that exercise will trigger premature labour.

How important is it to consult with your gynaecologist if you want to exercise during pregnancy?

Dr. Baer Altorfer: If a pregnant woman feels unwell or uncertain, she should never hesitate to consult her gynaecologist. It is better to err on the side of caution. It is our job as doctors to provide patients with clear information so that they feel safe and comfortable at all times. A relationship of trust is very important.
