Low levels of physical activity during pregnancy constitute a significant public health issue as increasing evidence suggests that the mother's lifestyle during pregnancy may influence the future health of her child. A physically active lifestyle during pregnancy has potential to improve metabolic health of mother and child and thus may play an important role in relation to counteracting the obesity epidemic and the increasing incidence of metabolic diseases that escalates globally.~However, less than four out of ten Danish pregnant women succeed to achieve 30 minutes of daily physical activity at moderate intensity as recommended by the Danish Health Authorities. The key gap in evidence and practice towards tackling the significant public health issue of being physically inactive during pregnancy is lack of evidence of how physical activity can be implemented. Only very few and scattered regional or municipal physical activity initiatives are currently targeting Danish pregnant women, and these are mainly targeted overweight women. Implementing and validating means to empower the pregnant women to be physically active have the potential to establish the norm of being physically active during pregnancy and might halt the negative spiral effect of physical inactivity, obesity and metabolic diseases that escalates globally.~The aim of FitMum RCT is to evaluate the effects of structured supervised exercise training and motivational counseling supported by health technology on physical activity level during pregnancy. The two exercise programs are designed to meet the motivators and overcome the specific barriers for physical activity among pregnant women. The programs will be tested in a three-armed randomized controlled trial including 220 healthy, physically inactive, pregnant women.~FitMum is carried out in collaboration between University of Copenhagen, Nordsjaellands Hospital, Technical University of Denmark, Aarhus University and international researchers.~During the COVID-19 pandemic supplies of interventions and test visits are periodically changed. During lockdown periods, all interventions and test visits (except delivery) are converted into online versions. In EXE, the water exercise sessions are replaced with online land exercises. All land exercise sessions consist of 30 min of aerobic exercise where the participants exercise on their own followed by 30 min of supervised online group resistance training. All individual and group MOT sessions are held online. As much data as possible is collected during the pandemic, but in some periods, biological samples and DXA scans have been cancelled and participants were weighed at home.
A physically active lifestyle during pregnancy has potential to improve maternal and child health. However, less than four out of ten Danish pregnant women succeed to achieve 30 minutes of daily physical activity at moderate intensity as recommended by the Danish Health Authorities. This project investigates how to implement physical activity in pregnant women´s everyday life by testing the efficacy of two very different exercise programs on physical activity level during pregnancy.
