Objectives: Although regular exercise during pregnancy is linked with improved health outcomes for both mother and foetus, many pregnant women are inactive. The purpose of this study was to use organismic integration theory (OIT) as the guiding theory for examining the relationship between autonomous and controlled motives for (a) exercise behavior reported over a typical week and barriers to exercise and (b) exercise and stage of pregnancy (i.e., trimester). %26lt;br%26gt;Design: Cross-sectional. %26lt;br%26gt;Methods: Participants (N = 75) were pregnant women who completed a multi-component, Internet-based survey. %26lt;br%26gt;Results: Multiple regression analyses showed that identified regulation predicted greater exercise behavior and fewer exercise barriers, irrespective of trimester. Further analyses indicated that women in the first trimester reported significantly higher identified regulation compared to women in either second or third trimesters. %26lt;br%26gt;Conclusions: Overall, these findings reinforce the importance of distinguishing controlled from autonomous exercise motives and demonstrate the tenability of Oil for enhancing our understanding of exercise behavior and barriers during pregnancy.
