Fourteen women performed treadmill exercise for continuous 10-minute periods at levels of 2, 3 and 4 mets in the second and third trimester of pregnancy and again postpartum. The percentage increase in heart rate in response to exercise was similar during pregnancy and postpartum while systolic blood pressure was increased only during pregnancy. Maternal plasma noradrenaline levels at peak exercise increased 64% (p less than 0.005), 42% (p less than 0.005) and 29% (NS) in the 3 studies respectively compared to resting levels at these times. Ten women experienced increased uterine activity during the exercise or recovery periods. Fetal heart rate was increased (p less than 0.05) by exercise but this was independent of uterine contractions and plasma noradrenaline levels.
14名女性在妊娠中期和晚期以及产后分别以2、3和4代谢当量的水平进行了连续10分钟的跑步机运动。运动时心率增加的百分比在孕期和产后相似，而收缩压仅在孕期升高。与这些时间的静息水平相比，在3项研究中，运动高峰时母体血浆去甲肾上腺素水平分别升高了64%（p<0.005）、42%（p<0.005）和29%（无统计学意义）。10名女性在运动或恢复期间出现子宫活动增加。运动使胎儿心率增加（p<0.05），但这与子宫收缩和血浆去甲肾上腺素水平无关。
