| INTRODUCTION: Many pregnant women wish to engage in aerobic exercise during pregnancy but are concerned about possible adverse effects on the outcome of pregnancy. In recent years there has been a great increase of scientific research regarding physical exercise during pregnancy and the pregnancy outcome (Barakat et al, 2008. Barakat et al, 2009). Nevertheless, many doubts persist relative to the response to exercise by the pregnant woman. Limited information is available about the comparison of the type of exercise (land-water) and the maternal response. Our aim was to assess and to compare maternal heart rate during land and water exercise of the same intensity level. MATERIAL AND METHODS: 15 healthy pregnant women (nulliparous) at third trimester were evaluated (mean of gestational age=245 ± 14.3 days). Other maternal data were recorded including parity, smoking, occupational activity and physical activity habits. The physical activity protocol consisted of a session of aerobic exercise (25 min), the intensity of activity was evaluated by Borg Scale (level 12=light), maternal heart rate was registered by Polar F6 model. Aquatic session of similar intensity was developed and maternal heart rate was registered also. Comparison of data of maternal heart rate was made by Student t Test. RESULTS: Our results shows that exercise developed on land produce larger elevations (mean: 110,86±6,1) in maternal heart rate than water activities (mean: 105,40±6,1) at same level of intensity, although no significant differences were found (p=0.09). DISCUSSION: The aim of our study was to compare the effects of land and water exercises during pregnancy. O¿Neill et al. (1992) studied the accuracy of Borg's ratings of perceived exertion in the prediction of heart rates during pregnancy but they didn't include aquatic exercises. In our opinion maintenance of the corporal weight caused by the pregnancy is possibly the cause of these differences, naturally during the aquatic activities this extra corporal weight caused by the pregnancy is attenuated (Granath et al, 2006). | |
