Influence of Physical Stress on the Fetal and Maternal Hemodynamics and the Cervical Structure in Singleton and Twin Pregnancies

Objective: Aim of the study was to examine the impact of various physical activity on fetal and maternal hemodynamics and the cervical structure. Methods: 12 women (6 singleton and 6 twin pregnancies) agreed to participate. Examinations were performed longitudinally at intervals of 4–5 weeks. Before and after each exercise (standing, jogging and cycling)we analysed:1)Maternal: pulse, blood pressure (RR), contractions, cervical length (CL), funneling width (FW), difference of CL in both positions, lactate, O2 and CO2, pulsatility index (PI) of the uterine artery.2)Fetal: FHR, PI of umbilical artery and middle cer…
