Pregnancy & Exercise: French Study Shows Benefits of Staying Active

For decades, conventional wisdom cautioned pregnant women against strenuous activity. However, a growing body of evidence, and a new study underway in France, demonstrates that exercise during pregnancy isn’t just possible—it’s beneficial for both mother and baby. Since 2024, the Preg’Mouv study in Clermont-Ferrand has been observing and supporting expectant mothers to better understand how to move safely throughout pregnancy, with positive effects already becoming apparent.

Addressing Fears and Promoting Safe Movement

Despite widespread recommendations for physical activity during pregnancy, many women remain hesitant, fearing they might “do something wrong” or endanger their baby. The Preg’Mouv study was created specifically to address these concerns and identify the best ways to support women in adopting a safe and appropriate exercise routine throughout their pregnancy.

Real-World Benefits for Expectant Mothers

Marie, a participant in the Preg’Mouv study who is nearing the end of her second pregnancy, exemplifies the positive impact of the program. A long-time athlete, she finds movement essential for both her physical and mental well-being. “I’m here to do physical activity, but also to share a moment with other pregnant women,” she shared. “The coach is very attentive and gives us a lot of advice. It’s a really nice moment in the week.”

For Marie, the sessions provide a valuable respite from a busy life. “I already have a three-year-old daughter. Between work, home, and family, finding time for myself isn’t easy. This is a moment just for me and my baby.” She reports feeling energized and healthy, stating, “Pregnancy isn’t an illness, and you really feel that here. You leave the session with energy, feeling good.”

A Tailored Approach to Exercise

Preg’Mouv centers on the principle of adapted physical activity. Sessions, offered up to three times per week, are led by two instructors in adapted physical activity from ASM Omnisports and the Clermont-Ferrand Municipal Sports Office. Each exercise is carefully designed to accommodate each participant’s abilities, vulnerabilities, and anxieties. François-Gabriel Guillemin, a coach with ASM Omnisports, explained the protocol: “The women are included in the study between 14 and 21 weeks of pregnancy, and we offer them physical activity until 39 weeks.”

François-Gabriel, holding a master’s degree in STAPS (Studies of Physical Activities and Sports), leverages his diverse training—including fitness education and swimming instruction—to create beneficial and secure exercises. He notes that a common initial concern among participants is uncertainty about what is safe during pregnancy. “They wonder what they are allowed to do or not, if certain movements are dangerous for the baby. There are still many misconceptions, like the idea that sports could harm the pregnancy. Our role is to dispel these ideas while remaining very vigilant about precautions.”

Positive Outcomes for Mothers and Babies

Élodie, eight months pregnant with her second child, joined the program on her midwife’s recommendation. “I usually play sports, and I wanted to be supervised by someone who really knows about pregnancy. Here, we’re a good team, with women at different stages of pregnancy. The sessions are adapted, and even if the slots are short, it’s enough.” She’s already experiencing benefits, including reduced pain and fatigue, and hopes for a smoother postpartum recovery. “There’s confidence, well-being, and we’re able to better manage weight gain. And yes, it’s important to feel beautiful.” Another participant noted benefits for her baby, stating, “I feel him well, I feel like he appreciates it. We also learn a lot about breathing.”

Chloé Barasinski, a midwife, researcher, and the head of the Preg’Mouv study, emphasizes the scientific basis of the project. “We know that physical activity during pregnancy is beneficial for the physical and mental health of mothers, but also for their future babies. It’s recommended in France and internationally. Yet, pregnant women still struggle to participate.” She attributes this to a persistent culture of excessive caution. “We still think you have to stay calm and avoid movement. In reality, adapted physical activity improves the daily lives of mothers.”

The study has also documented positive effects on babies, including a lower incidence of macrosomia (large babies) at birth, a more balanced birth weight, and potential benefits for cognitive development.

The Power of Social Connection

Beyond the medical benefits, Preg’Mouv highlights the importance of social support. “The sessions are always offered in groups, in person or remotely. Social connection consistently emerges as a major motivating factor,” observes Chloé Barasinski. Participants report forming lasting bonds, often continuing to connect after childbirth. One mother who has already given birth shared, “What I remember most today is the social connection. The sessions relieved back pain, provided relaxation, but above all, we supported each other. We shared the pregnancy, then the new life as a mother, and we continue to see each other.”

What’s Next for Preg’Mouv?

The Preg’Mouv study is ongoing, with plans to include over 200 women. Participants are followed throughout their pregnancies and for a year after delivery. A control group, receiving standard medical care but not participating in the exercise sessions, allows for a precise comparison of outcomes. Ultimately, the goal is to “analyze the results to propose a model of physical activity that is accessible, effective, and integrable into a comprehensive health plan, including from an economic perspective,” explains the study leader. The inclusion of a control group aims to demonstrate that movement is not only possible but also beneficial with proper support.
