THERAPEUTIC EXERCISE FOR INSULIN-REQUIRING GESTATIONAL DIABETICS - EFFECTS ON THE FETUS - RESULTS OF A RANDOMIZED PROSPECTIVE LONGITUDINAL-STUDY

Regular physical activity is an establish therapeutic adjunct in diabetes, but has not been offered to pregnant diabetics in the past; for sports might induce significant cardiovascular and hormonal changes that are able to reduce blood flow to the uterus and thus limit oxygen transfer to the fetus. Studying the impact of a medically supervised exercise program on gestational diabetes mellitus [GDM) in a randomised prospective longitudinal study, this paper aims to assess the effects of maternal moderate and strenuous exercise on the fetus. By evaluating shortterm fetal responses as reflected in heart rate patterns (FHR) and longterm-pregnancy complications and neonatal outcome, our results suggest that - in absence of ominous FHR changes or significant changes in uterine activity following the exercise sessions or increased diabetes-related peri- and neonatal morbidity - regular physical activity seems to be a safe therapeutic option for the fetus of GDM mothers.
