Eighteen pregnant women affected with fetal growth retardation in the last trimester were exercised. The mean maternal heart rate increased significantly from 140 beats per minute (bpm) (120-188 bpm) at rest to 172 bpm (163- 178 bpm) after exercise. The mean exercise intensity was 65% (56-85%) of submaximal exercise. Maternal systolic blood pressure rose significantly from a mean of 116 mmHg (100-140 mmHg) to 159 mmHg (120-190 mmHg) and the diastolic blood pressure rose significantly from a mean of 72 mmHg (55-110 mmHg) to 90 mmHg (80-110 mmHg). The umbilical artery pulsatility index (PI), after an initial decrease, showed a 12% rise at 8, 16 and 30 minutes of recovery. Patients who smoked had a significantly higher umbilical artery PI before and after exercise. Less active Patients had a higher PI before and after exercise than active ones. Infants weighing 1.9-2.5 kg at birth had a higher PI than those weighing 2.6-3.3 kg. Male fetuses had a significantly higher PI than female fetuses.
18名在妊娠晚期患有胎儿生长受限的孕妇进行了运动。孕妇平均心率从静息时的每分钟140次（bpm）（120 - 188 bpm）显著增加至运动后的172 bpm（163 - 178 bpm）。平均运动强度为次最大运动的65%（56 - 85%）。孕妇收缩压从平均116 mmHg（100 - 140 mmHg）显著升至159 mmHg（120 - 190 mmHg），舒张压从平均72 mmHg（55 - 110 mmHg）显著升至90 mmHg（80 - 110 mmHg）。脐动脉搏动指数（PI）在最初下降后，在恢复的8分钟、16分钟和30分钟时显示上升了12%。吸烟的患者运动前后脐动脉PI显著更高。活动较少的患者运动前后PI高于活动较多的患者。出生体重1.9 - 2.5 kg的婴儿PI高于体重2.6 - 3.3 kg的婴儿。男性胎儿的PI显著高于女性胎儿。
