The purpose of this study was to assess the effect of strenuous symptom-limited exercise on umbilical and uterine blood flow.
Twenty-two primiparous women between 30 and 34 weeks of gestation were recruited. At rest, umbilical and uterine artery waveforms were assessed by measuring the pulsatility index. This was followed by a symptom-limited incremental exercise test. Fetal umbilical and maternal uterine artery circulations were assessed after exercise.
Strenuous maternal exercise was demonstrated by the significant change in physiologic parameters, which was associated with an immediate increase in fetal heart rate, a significant increase in the right uterine artery pulsatility index, and a reduction in the umbilical artery pulsatility index.
The modest change in the uterine artery pulsatility index without an adverse change in the umbilical artery pulsatility index indicates that a single bout of maximum symptom-limited exercise does not have immediate adverse fetal or maternal cardiovascular effects.
本研究旨在评估剧烈的症状限制性运动对脐血流和子宫血流的影响。
招募了22名妊娠30至34周的初产妇。休息时,通过测量搏动指数评估脐动脉和子宫动脉波形。随后进行症状限制性递增运动试验。运动后评估胎儿脐动脉和母体子宫动脉循环。
生理参数的显著变化表明母体进行了剧烈运动,这与胎儿心率立即增加、右子宫动脉搏动指数显著增加以及脐动脉搏动指数降低有关。
子宫动脉搏动指数有适度变化,而脐动脉搏动指数无不良变化,这表明单次最大症状限制性运动不会立即对胎儿或母体心血管产生不良影响。
