It is known that physical exercise increases plasma volume in healthy adults, also arterial and both venous compliance and capacitance is improved by exercise. Since abnormal circulatory functions are common in formerly preeclamptic women, we want to study the effects of exercise in this specific group, and compare these results with women after an uneventful pregnancy. In preventive perspective it would be beneficial that also formerly preeclamptic women show a circulatory adaption to aerobic exercise, possibly they could improve their haemodynamic profile prior to their pregnancy
