Key Points

This research aims to examine how physical activity and BMI relate to placental structure and vascularization during pregnancy.
Analyzed data from the FitMum Randomized Controlled Trial
Investigated the impact of physical activity on placental growth and vascularization
Assessed the relationship between pre-pregnancy BMI and placental outcomes
Physical activity during pregnancy was linked to increased placental growth
No significant changes in placental vascularization were attributed to physical activity
Higher pre-pregnancy BMI correlated with reduced placental vascularization

Implication

Controlled trial uncovers links between physical activity, BMI, and placental changes in pregnant individuals, suggesting implications for maternal health.

Abstract

• This study suggests physical activity during pregnancy stimulates placental growth. • Physical activity during pregnancy did not affect placental vascularization. • A high pre-pregnancy BMI was associated with decreased placental vascularization.
