Physical activity, especially exercising, plays an enormously important role for a woman's well-being during pregnancy. However, the number of women engaged in physical activity during pregnancy depends on the access to information, possible barriers and motivators and women's attitudes. The aim of this research was to examine which attitudes are more likely to represent either barriers or motivation for conducting physical activity during pregnancy as well as to what extent it is connected with the labour and its outcome, including the apearance of pain in pelvic and lower back area. 167 women participated in the survey, having been questioned within the first three days following their labour. Statistical analysis included descriptive statistics. Fisher's, Hi-square test, and Mann Whithey U Test were used to determine the difference between the participants. Sperman's correlation test and Kramer's V were used to establish the connection between the physical activity and the lower back and pulvic pain. Based on the data collected a larger number of pregnant women were physically inactive. Those who claimed to be active during pregnancy had used to be regularly active prior to pregnancy too. They had practiced walking, pilates and yoga activities. The intensity of training was more extensive while the time they spent doing various activities was longer. Their most favourite motivator was the improvement of physical and mental health, relaxation, better physical fitness level, easier labour and post-labour recovery. High percentage of participants agreed that exercising is useful and that gynecologists should provide consistent information about the positive effects of exercising. The pregnant women that are physically active during pregnancy not only suffer less pulvic pain but the intensity of pain is smaller. They also claim they are better fit during labour. It can be concluded that medium intensity physical activity has positive impact on lower back and pulvic pain and the level of fitness during labour. Finally, pregnant women have been informed of the benefits of exercising, although they are not prone to practicing it.
