To evaluate the effect of maternal isometric exercise on the placental blood flow as reflected by the velocimetric indices PI and RI derived from placental arteries.
Thirty-four healthy women with normal singleton pregnancies between 22 and 35 weeks of gestation.
All subjects underwent an isometric handgrip exercise test. Maternal blood pressure and heart rate together with placental PI and RI were measured at rest, during the exercise and in the post-exercise recovery phase. All Doppler measurements were obtained using the Simultaneous Multigate Spectral Doppler Imaging (SM-SDI) technique, a new ultrasound modality that enables a Doppler study of multiple locations to take place within a very short time.
There was a significant increase in the mean values of the maternal blood pressure and heart rate during the exercise and a significant decline in the recovery phase. There was no significant change in the mean values of the Doppler indices throughout the examination.
Isometric handgrip exercise test during pregnancy does not affect the impedance of the placental circulation.
通过源自胎盘动脉的血流速度指标PI和RI来评估孕妇等长运动对胎盘血流的影响。
34名妊娠22至35周的单胎健康孕妇。
所有对象均接受等长握力运动测试。在休息时、运动期间和运动后恢复阶段测量孕妇血压、心率以及胎盘PI和RI。所有多普勒测量均使用同步多门谱多普勒成像（SM-SDI）技术获得，这是一种新的超声模式，能够在极短时间内对多个部位进行多普勒研究。
运动期间孕妇血压和心率平均值显著升高，恢复阶段则显著下降。整个检查过程中，多普勒指标的平均值无显著变化。
孕期等长握力运动测试不影响胎盘循环的阻抗。
