Running and walking during pregnancy: Effects of abdominal belt and running cadence

The figure above shows a representative case from the study showing overall improved running quality score due to running with the abdominal belt. The improvements come from all three main sub-components of running quality, including better pelvic dynamic stability, better symmetry, and lowered impact loading. This is part of some exciting new research that has emerged as part of the Ph.D. research of Marion Raballand at UC Louvain University. For more details on the study, read the full research abstract below. 

"Runeasi helps me guide moms returning postpartum, to make this return to impact more reassuring and objective"—Marion Raballand, PT, PhD Student

“Aim of the study: The aim of our study was to determine if the use of an abdominal support belt and a 10% increased cadence, separately and together, can improve the impact magnitude and duration, the pelvic instability, and the abdominal discomfort during walking and running in pregnant women. 

Methods: 14 women participated to the walking protocol and 12 to the running protocol. The experiment consisted in an appointment where women had to run or walk on a treadmill under different conditions: with abdominal belt and spontaneous cadence, with abdominal belt and 10% increased cadence, without belt and spontaneous cadence and without belt and 10% increased cadence. Collected data were abdominal discomfort, impact magnitude and duration and pelvis instability. 

Results: In running, the impact magnitude, impact duration and pelvis instability are significantly improved while wearing a belt. The increased cadence significantly increases the impact magnitude. In walking, discomfort and pelvis instability are significantly improved with the belt. However, the increased cadence does not bring any change. 

Conclusion: Our results are encouraging because the abdominal belt improves the values and decreases discomfort, which may encourage running and walking during pregnancy. On the other hand, increasing cadence did not show any effect in our study, but it would be interesting to deepen the research to see the long-term effects of it.”

Marion is an expert in perinatality and abdomino-pelvic health in women's running. Her clinical activity at MoveMum is centered, among other things, on pre and post natal physiotherapy. She tries to make pregnant women and health professionals aware of the importance of maintaining regular physical activity during pregnancy. She is also a doctoral student in motricity sciences and her research focuses on the interest of sport during pregnancy (Free University of Brussels, Belgium). In addition, Marion specializes in the management of sports pathologies related to running.

She began her career as a physiotherapist in 2009. After an experience at the Belgian French-speaking athletics league (LBFA), she joined the sports medicine branch of the Saint-Luc clinics in 2011, before becoming co-founder of the Wolu Sport Clinic. Marion is involved in several continuing education courses at Parnasse-ISEI (Brussels, Belgium) and at the Catholic University of Louvain (Brussels, Belgium).

Finally, Marion practices running with passion and even more so since she became a mother. This practice is deeply rooted in his family and professional life. She is one of the best runners in the Brussels region.

1. Global movement quality

Track and improve your client’s Runeasi running quality. Identify their weakest link with our advanced visualisation.

2. individual recommendations

Get individual training and cueing recommendations to improve your client’s weakest link.

3. Real-time feedback


4. Session trends

Learn more about your client’s running quality during daily training. Our session trends show when and where the quality drops with fatigue.

5. Quick comparisons

Compare pre-post data to show intervention effects on the movement quality. 


1. No motion artifacts. The Runeasi belt is secured tightly against the body and the skin to capture the actual movements of the body’s center of mass. Attaching or clipping the sensor directly to the pants would allow the sensor to wobble from side to side (i.e., measuring the wobbling of the pants, and not the human body.

2.  Easy to standardize the sensor’s positioning. The Runeasi belt makes it easy to consistently position the sensor close to the center of mass. Attaching the sensor directly to the pants would dramatically affect the reliability of the outputs as the height and tightness of the pants will affect the results. Moreover, these pants attachments often shift sideways while running which further decreases the data quality. 

 3. Comfortable to wear.  Hundreds of runners confirmed that they immediately forget about our belt while running. This allows them to move without any restrictions and allows us to capture movements that are representative of a client’s true biomechanics.
