Brik M, et al. - Researchers performed a randomized controlled trial to assess differences in maternal weight gain and fetal cardiac function according to exercise during pregnancy. This trial was conducted at Hospital de Torrejón, Madrid, involving 120 pregnant women, allocated into Exercise Group (EG) and Control Group (CG). No association was found between performing an exercise during pregnancy and a reduction in maternal weight gain, however, a higher weight loss 6 weeks postpartum. Findings suggested an association of performing an exercise with an increased Ductus Arteriosus Pulsatility Index (DAPI) at 20 weeks and Ejection Fraction (EF) at 36 weeks, which could translate into adaptive mechanisms when analyzing fetal cardiac parameters.
