Introduction:
The question of physical activity during pregnancy has been widely discussed, including issues concerning the health and safety of both pregnant women and their children. Continuous progress in this field, accelerated by scientific developments, has led to large-scale research across the globe. There are numerous publications concerning physical activity in pregnant women which discuss issues such as safe forms of physical activity during pregnancy, its intensity, frequency and duration. International literature provides guidelines concerning the kind of physical exercise which are suitable or should be avoided by pregnant women. Another important problem is the question of measuring physical activity in pregnant women. Researchers propose the application of questionnaires, which enable to assess the level of physical activity and corresponding energy expenditure in pregnant women. To the best of the authors’ knowledge, currently there is no questionnaire for assessment of physical activity during pregnancy that would be commonly accepted in Poland. Therefore, there is a pressing need to fill this gap in Polish literature. Based on the original version of the Pregnancy Physical Activity Questionnaire, this paper aims to present the Polish version of the questionnaire (PPAQ-PL), along with detailed instructions for conducting relevant calculations. The authors› intention is to allow the use of standardized tools to measure the physical activity of pregnant women in Poland.
