title: The effect of maternal exercise on umbilical artery blood flow in insulin-dependent diabetics.
abstract: Nine insulin-dependent diabetic women underwent a moderate exercise test. The mean exercise intensity achieved was 65% (50-80%) of submaximal exercise. The maternal heart rate rose significantly after exercise from a mean of 85 b.p.m. (60-109 b.p.m.) to a mean of 140 b.p.m. (112-168 b.p.m.). Maternal systolic blood pressure rose significantly from a mean of 115 mmHg (90-130 mmHg) to a mean of 157 mmHg (145-180 mmHg). The diastolic blood pressure also rose, but insignificantly, from a mean of 71 mmHg (65-90) mmHg to a mean of 85 mmHg (80-90) mmHg after exercise. The mean umbilical pulsatility index (PI) showed significant decrease at 2 and 6 minutes of recovery from exercise and subsequently showed a significant rise after 20 minutes. This rise continued even after a full 30 minutes of recovery from exercise.
