The effects of a brief period of supine exercise on fetal heart rate (FHR) was studied in 25 healthy, regularly exercising women, 12 in the late second trimester and 13 in the mid third trimester. Although statistically significant increases in maternal mean arterial pressure and pulse occurred, the exercise intensity was mild, with the average percent maximal pulse being 46 +/- 5% and 49 +/- 5% in the second and third trimester groups, respectively. Small increases in FHR were seen in both groups, which were insignificant statistically and physiologically. No patient experienced significant FHR abnormalities as a result of the supine exercise sequence. The findings suggest that pregnant women may continue submaximal supine exercise of short duration into the mid to late third trimester.
对25名健康且有规律锻炼习惯的孕妇进行了研究，观察短时间仰卧运动对胎儿心率（FHR）的影响。其中12名处于孕中期晚期，13名处于孕晚期中期。尽管孕妇平均动脉压和脉搏在统计学上有显著升高，但运动强度较轻，孕中期组和孕晚期组的平均最大脉搏百分比分别为46±5%和49±5%。两组胎儿心率均有小幅升高，在统计学和生理学上均无显著意义。没有患者因仰卧运动序列出现显著的胎儿心率异常。研究结果表明，孕妇在孕晚期中期至晚期可以继续进行短时间的次最大强度仰卧运动。
