Exercise to Improve Heart and Metabolic Health After Childbirth in Women at High Risk for Preeclampsia

2. November 2026 aktualisiert von: LAI KWAN LAM, Chinese University of Hong Kong

Enhancing Cardiometabolic Health in Postnatal Women at High-Risk for Preeclampsia Through Exercise Intervention

Women who develop hypertensive disorders of pregnancy have an increased risk of cardiovascular disease later in life. Whether exercise during the postpartum period improves cardiometabolic health in this population remains unclear.

This pilot randomized controlled trial will recruit 40 women who were identified as being at high risk for preeclampsia during pregnancy and subsequently developed a hypertensive disorder of pregnancy. Participants will be enrolled 6 to 8 weeks after delivery and randomly assigned to a 12-week exercise program or standard postnatal care. The exercise program will consist of three sessions per week combining moderate-intensity aerobic exercise, resistance training, and pelvic floor exercises.

Cardiovascular function, blood pressure, blood markers of cardiometabolic health, physical fitness, and body composition will be assessed before and after the 12-week period. Changes in mood, sleep quality, and health-related quality of life will also be evaluated. The study will provide preliminary evidence on the effects of postpartum exercise in this population and inform the design of a larger trial.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: Postpartum Exercise Program

Participants will complete a 12-week exercise program consisting of three supervised sessions per week. Each session will combine moderate-intensity aerobic exercise, resistance training, and pelvic floor exercises. Exercise intensity will be adjusted to individual fitness levels and monitored using heart rate and ratings of perceived exertion.
Verhalten: Postpartum Exercise Program

Participants assigned to the exercise group will undertake a 12-week program comprising three supervised 60-minute sessions per week. Each session includes a 5-minute warm-up, 20 minutes of moderate-intensity aerobic exercise on a treadmill or stationary bicycle, 20 minutes of resistance training, 10 minutes of pelvic floor exercises, and a 5-minute cool-down. Exercise intensity will be individualized and progressively adjusted according to heart rate and rating of perceived exertion.
Kein Eingriff: Standard Postnatal Care

Participants will receive standard postnatal care, including routine health check-ups and general advice on postnatal health. They will not receive a structured exercise program as part of the study.
