Abstract:
Effect of exercise on placental blood flow and fetal heart rate was studied using Acuson 128 color computer ultrasound equipment The subjects were ten healthy women ranging from 27 to 35 gesta- ' tional weeks (mean 30.7 weeks). After exercise, the matcrnal mean arterial pressure increased significantly, maternal heart rate rose and amounted to 60%-75% of maximal heart rate (both P0.05). The fetal heart rale rose but within normal limit. These showed that the responses of maternal blood vessel and fetal blood vessel of placenta to the exercise were different This intensity and time of exercise could improve uterine blood flow and reduce its vascular resistance. However, they didn't influence the umbilical artery blood flow. Also the change of fetal heart rate was within normal limit. It is concluded that the moderate and non-exhaustive maternal exercise can improve the supply of the placental blood flow and benefit to the 2nd and 3rd trimister healthy pregnant women.
