Regular exercise can positively affect maternal well-being, reduce the risk of pregnancy-related complications, and support optimal fetal development. Additionally, physical activity may contribute to a reduced need for C-sections and better postpartum recovery. Despite these benefits, global trends indicate a decline in physical activity levels, exacerbated by lifestyle changes such as remote work. This highlights the importance of promoting healthy habits among women of reproductive age to improve perinatal outcomes and the long-term health of both mothers and their children. Objective: The aim of this study was to investigate the effects of physical activity during pregnancy on the health of mothers and babies after birth. Methods: A prospective cohort study was conducted in a tertiary care hospital in northern Poland from October 2024 to December 2024. Participants were 205 pregnant women with no medical contraindications to physical activity. The group was selected on the basis of a questionnaire with original questions and the Get Active Questionnaire for Pregnancy (GAQ-P). The effects of physical activity during pregnancy on maternal and infant health after delivery were assessed using questionnaire data and medical records. Frequency analysis supported by chi-squared coefficient; Cramer\u2019s V coefficient and Spearman\u2019s rank correlation were used to answer the research questions. Results: The study showed that the frequency of physical activity had an effect on the incidence of perineal trauma, the baby\u2019s birth weight, and the baby\u2019s degree of saturation after birth. The intensity of physical activity during pregnancy may influence the duration of the first stage of labor, while the duration of physical activity may influence the duration of the second stage of labor and reduce the number of operative deliveries. Conclusions: Although physical activity has a huge impact on the course of pregnancy and the health of both mother and child after birth, more research is needed to draw clear conclusions. In our study, a beneficial effect of physical activity on the reduction in cesarean sections can be observed. However, the effects on perineal injuries, length of labor, and birth weight require further research, as our findings indicate that higher exercise frequency was associated with both positive outcomes, such as fewer cesarean sections, and potential risks, including an increase in macrosomia and perineal tears. A broader analysis of co-factors influencing these results is needed to fully understand these relationships.<\/jats:p>","DOI":"10.3390\/jcm14072325","type":"journal-article","created":{"date-parts":[[2025,3,28]],"date-time":"2025-03-28T13:36:49Z","timestamp":1743169009000},"page":"2325","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Associations Between Physical Activity in Pregnancy and Maternal, Perinatal, and Neonatal Parameters: A Single-Center Prospective Cohort Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9776-0326","authenticated-orcid":false,"given":"Paulina","family":"Majewska","sequence":"first","affiliation":[{"name":"Department of Obstetric and Gynaecological Nursing, Institute of Nursing and Midwifery, Faculty of Health Sciences with the Institute of Maritime and Tropical Medicine, Medical University of Gdansk, 80-210 Gdansk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8565-027X","authenticated-orcid":false,"given":"Anna","family":"Szablewska","sequence":"additional","affiliation":[{"name":"Department of Obstetric and Gynaecological Nursing, Institute of Nursing and Midwifery, Faculty of Health Sciences with the Institute of Maritime and Tropical Medicine, Medical University of Gdansk, 80-210 Gdansk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Moreno-Fernandez, J., Ochoa, J.J., Lopez-Frias, M., and Diaz-Castro, J.
