This study was conducted to determine the impact of maternal exercise on fetal breathing and fetal body movement, which are commonly used for assessing fetal well-being. Twelve healthy patients with a range of gestational ages of 26 to 36 weeks, who actively exercised throughout pregnancy, participated in the study. The patients walked on a motorized treadmill using a modified Bruce protocol until the maternal heart rate reached 75% of the age-predicted maximal heart rate. Fetal activities (fetal breathing and fetal body movement) were continuously monitored with real-time ultrasonography for 20 minutes before and after the standardized exercise test. Our results demonstrate that there is a significant increase in maternal heart rate and blood pressure associated with exercise. In addition, there is a significant decrease in the total duration and frequency of fetal breathing and fetal body movements following acute maternal exercise.
本研究旨在确定母体运动对胎儿呼吸和胎儿身体运动的影响，这两项指标常用于评估胎儿健康状况。12名孕周在26至36周之间、整个孕期都积极运动的健康孕妇参与了该研究。这些孕妇在电动跑步机上按照改良的布鲁斯方案行走，直至母体心率达到年龄预测最大心率的75%。在标准化运动测试前后，通过实时超声对胎儿活动（胎儿呼吸和胎儿身体运动）进行连续20分钟的监测。我们的结果表明，运动与母体心率和血压显著升高相关。此外，母体急性运动后，胎儿呼吸和胎儿身体运动的总时长及频率显著降低。
