简要总结
The main theme of this study focuses on providing evidence of the impact of antenatal physical activity on maternal/foetal cardiovascular changes during pregnancy and maternal cardiovascular adaptations during the early postpartum period.
详细描述
Overwhelming research supports the general benefit of antenatal physical activity (APA) for pregnant women, but there is a lack of knowledge about the influence of exercise on cardiovascular physiology in healthy and overweight pregnant women and their foetuses. Also some research supports the theory of foetal programming; which establish that maternal habits during pregnancy will impact in-utero environment, so if this maternal habits are healthy ones they could improve foetal health.
Cardio vascular disease (CVD) was the top cause of death all over the world in 2015. In Wales CVD as cause of death is still one of the top ones. However, these statistics could be improved if people adopt healthier lifestyle habits, since 54% and 45% of Welsh women are overweight/obese or sedentary respectively. Pregnancy seems to be a teachable moment for women and the starting point of adopting healthy life-style habits. Therefore, by introducing Welsh pregnant women to exercise, there is the potential to improve their health and of their foetuses an also exert an exponential impact on future generations.
The main theme of this study focuses on providing evidence of the impact of APA on maternal/foetal cardiovascular changes during pregnancy and maternal cardiovascular adaptations during the early postpartum period.
This is a 3-year study carried out in Swansea University, Singleton Hospital.
The project leading to this application has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 663830.

研究组 & 干预措施
Exercise group
An antenatal physical activity (APA) programme will be designed for participants in the exercise group.
干预措施: Exercise group (Behavioral)
Control Group
Sedentary participants.
结局指标
主要结局
Changes in maternal heart rate during and after pregnancy.
时间窗: 18 and 36 weeks of gestation, 12 weeks postpartum.
Maternal heart rate at rest and after exercise would be recorded in beats per minute to be analysed and compared inter and intra group.
Changes in maternal cardiac output during and after pregnancy.
时间窗: 18 and 36 weeks of gestation, 12 weeks postpartum.
Maternal cardiac output at rest, during exercise and after exercise measured in L/min would be recorded from study participants to analyse and compare potential changes inter and intra group.
Foetal heart rate
时间窗: 36 weeks pregnancy
Foetal heart rate baseline would be measured at rest, during and after exercise. It would be analysed and compared in between groups.
Changes in maternal heart rate variability during and after pregnancy
时间窗: 18 and 36 weeks of gestation, 12 weeks postpartum.
Maternal heart rate variability at rest, during and after exercise would be measured by r to r interval. It would be recorded and analysed to compare inter and intra group changes.
