Abstract
Introduction From a biological viewpoint, pregnancy is a unique process in which the function of all the body¿s control systems is modified to maintain both maternal and fetal homeostasis. With physical exercise becoming an integral part of life for many women, the question whether exercise during pregnancy may have an adverse impact on the well being of the new born has reached increasing importance. For healthy pregnant we examined the effect of protocol of moderate exercise (static bicycle) performed throughout the third trimester of pregnancy on circulation (umbilical and cerebral middle arteries) and behavior of fetal heart rate (FHR). Methods 20 pregnant healthy women in the third trimester were studied, age= 29.6 ± 4.3 and gestational age 239 ± 14.3 days. Relative to parity 10 of them were nulliparae and 10 multiparae. Exercise protocol consisted of 20 minutes of activity on a static bicycle (50-55% max cap). Pulsatility Index (PI) before and after exercise was obtained from doppler examinations in the umbilical and cerebral middle arteries. Other maternal data were recorded including smoking, occupational activity and physical activity habits. Results Our results shows no difference for measurements of IP, before and after exercise, for umbilical artery (p=0.06) and fetal cerebral middle artery (p= 0.10). We found an elevation of FHR between 11-36 beats/min (mean=24±7.6) and significant differences for changes of FHR between parity groups (p=0.04). Discussion Certain scientific evidence has demonstrated that physical exercise during pregnancy does not have adverse effects (Barakat et al, 2008; 2009). In that sense, our results shows no differences in IP of umbilical and fetal cerebral middle arteries in agreement with Ertan (2004). Changes in FHR caused by the exercise are a normal fetal reflex (Wolfe et al, 1994). The results presented support the evidence that light exercise during the third trimester of pregnancy does not have a negative influence on neither uterine and fetal circulation nor FHR.
