Conclusions
The present randomized controlled study compared two different exercise intervention strategies during pregnancy and found no effect of either structured supervised exercise training or motivational counselling on physical activity on GWG and obstetric and neonatal outcomes compared to standard care. The study proposes a novel method to estimate GWG for a standardized pregnancy period of 40 + 0 weeks, which may contribute to advance state-of-the-art in the obstetric research field.
