母体运动对胎儿血流影响的研究报道极少。为检测不同状况下母体运动对胎儿脐动脉血流速度波形的影响并确定何种运动强度安全。选择143例妊娠末三个月体健孕妇进行急性运动,所有病例在实验前24小时停止吸烟、喝咖啡、喝酒及应用药物(补铁剂除外)。实验分三个步骤进行:休息20min的基础对照期、持续5min的运动期和30min的恢复期。在运动期。孕妇在自行车功率上脚踏60次/min。220减去孕妇年龄作为最大心率,根据运动前后心率计
Maternal exercise on the impact of fetal blood flow reported very little. To detect the effect of maternal exercise on the fetal umbilical artery blood flow velocity waveform under different conditions and to determine what exercise intensity is safe. A total of 143 pregnant women of the third trimester of pregnancy were selected for acute exercise. All patients stopped smoking, drinking coffee, drinking alcohol and applying drugs (except iron supplements) 24 hours before the experiment. The experiment was divided into three steps: resting 20min basic control period, continuous 5min exercise period and 30min recovery period. During exercise. Pregnant women on the bicycle pedal power 60 times / min. 220 minus the age of pregnant women as the maximum heart rate, based on exercise before and after the heart rate meter
