“…Furthermore, in the present study, a bout of exercise of moderate intensity resulted in decreased mean UtA PI centiles in women with GDM but not in women with uncomplicated pregnancies. Regarding uncomplicated pregnancies, in the past, similarly to the findings of the present study, a bout of exercise of moderate intensity in pregnant women with uncomplicated pregnancies did not affect UtA PI centiles before and after exercise [37]. In fact, UtA PI was investigated in the present study because it is a marker of pregnancy health integrating and reflecting the state of different systems of maternal and fetal physiology, including utero-placental circulation and endothelial function, which are involved in highrisk pregnancies and more particularly GDM pregnancies [38,39].…”

Background: Gestational diabetes mellitus (GDM) is associated with aggravated oxidation capacity and utero-placental circulation, while aerobic exercise could improve both. The study aims to assess oxidation capacity and utero-placental circulation before and after a bout of aerobic exercise in GDM and uncomplicated pregnancies.; Methods: In this cross-sectional study, women with GDM (GDMs) and women with uncomplicated pregnancies(controls), underwent 30 min of moderate intensity cycling. Total antioxidant capacity (TAC), catalase activity (CAT), reduced glutathione (GSH), Uterine Arteries (UtA PI) and Umbilical Artery (UmA PI) pulsatility indexes were estimated prior-to, immediately after and one hour after exercise; Results: In each group, 25 pregnant women were included. In both groups, between prior-to and immediately after exercise, TAC and CAT increased, while GSH decreased, (p < 0.001). In GDMs, CAT was lower than controls at any time point (p < 0.05), while in GDMs delta(Δ) CAT (prior-to and immediately after exercise) was lower than controls (p = 0.003). In GDMs, UtA PI centiles decreased between prior-to and either immediately or one hour after exercise, while they did not change in controls. In GDMs, pre-conceptional BMI and weight gain predicted negatively ΔTAC (prior-to to one hour after exercise); Conclusions: Moderate intensity exercise bout improves oxidation capacity in GDM and uncomplicated pregnancies, although at a lesser extent in the former. Exercise leads to decreased UtA arteries resistance in women with GDM.

“…Interestingly, fetal well-being was preserved because of the maintenance of uterine oxygen uptake. The findings in human studies are equivocal with some researchers reporting no change in uterine blood flow (22,42,46) and others reporting decreased uterine blood flow with no associated fetal compromise (43,54,56). A systematic review by Skow et al (50) concluded that acute or chronic exercise does not negatively affect fetal HR and uterine blood flow.…”

It is well known that moderate exercise during pregnancy benefits maternal and fetal well-being. The benefits of more vigorous exercise for pregnant women are less clear. The boundaries of safe exercise during pregnancy remain a matter for continued research, which is important to the growing number of female athletes who plan on becoming pregnant. The purpose of this article is to discuss the existing research related to the physiological concerns of the pregnant endurance athlete specifically. Because endurance training includes prolonged and repetitive exercise bouts at varying intensities, topics will include the effect of high-intensity exercise on uterine blood flow and thermoregulation, metabolic, and musculoskeletal changes in pregnancy.

“…In recent years, the impact of physical activity during pregnancy on uterine-placental blood flow perfusion has caused widespread concern among scholars. Szymanski et al found that the mean uterine artery Doppler indices (pulsatility index, resistance index, systolic/diastolic ratio) did not significantly change during moderateintensity exercise (40-59% of heart rate reserve) according to the exercise guidelines of pregnant women, which indicates that after routine exercise, uterine arterial blood flow is not reduced (Szymanski and Kogutt 2018). However, after vigorous-intensity exercise (60-84% of heart rate reserve), all mean uterine artery Doppler indices showed reductions, which may cause decreased in uterine blood flow and may adversely affect fetal health.…”

Background: Hypertensive disorders of pregnancy are characterised by new onset of hypertension after 20 weeks gestation, proteinuria and other associated complications, which are major causes of adverse maternal and neonatal outcome. The benefits of physical activity on reducing the risk of essential hypertension, coronary atherosclerotic heart disease and type 2 diabetes are well documented, but the effcet of physical activity on gestational hypertension is inconclusive. This review presents the state of knowledge related to the impact of physical activity on gestational hypertension. Methods: We searched physical activity and gestational hypertension studies and highlight key articles with a focus on maternal health outcomes to best inform physical activity promotion efforts. Results: Physical activity during pregnancy can reduce the risk of gestational hypertension by improving placental blood flow perfusion deficiency, reducing oxidative stress, improving insulin resistance and improve the prognosis of maternal and fetus. Conclusion: Physical activity is of great benefit to improve the occurrence and development of gestational hypertension. Pregnant women should be guided according to individual factors and complications during pregnancy. However, there have no gold standard about physical activity norms based on gestational hypertension. Scientific computation of big data in real-world clinical research are needed in future research.

Uterine Artery Doppler Velocimetry During Individually Prescribed Exercise in Pregnancy

Abstract: Individually prescribed exercise according to guidelines for pregnant women does not adversely alter uterine artery Doppler values, suggesting that uterine blood flow is not reduced as a result of exercise.
