Abstract
Six healthy women in the last trimester of pregnancy were exposed to long term, strenous exercise on an ergometer bicycle. Before, during and after the exercise their heart rate, blood pressure, and respiration rate were continuously recorded and repeated samples of venous blood obtained. Fetal heart rate was monitored using an ultrasound instrument. In most cases a significant increase in fetal heart rate was recorded during maternal exercise but different patterns of change in fetal heart rate were observed. Also the levels of progesterone, estradiol, estriol and chorionic somatotropin in maternal plasma varied during maternal exercise.
The different patterns of changes in fetal heart rate and in the biochemical tests will be discussed.
