Aim 2. Determine the most effective exercise mode in pregnancy at risk of preeclampsia on improving birth and infant health outcomes. conditions: Pre-Eclampsia studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL interventionModelDescription: Pregnant women will be randomized to one of four groups: aerobic exercise, resistance exercise, combination (aerobic + resistance), or control (no exercise). All exercise participants will be prescribed exercise that meets guidelines of the American College of Obstetricians and Gynecologists (ACOG), American College of Sports Medicine (ACSM), and the American Heart Association (AHA); 150 minutes per week, moderate intensity (60-80% aerobic capacity, Rating of Perceived Exertion, rating of perceived exertion (RPE), 12-15) per week. These limits are the same as those that generated previous positive findings for our preliminary data. primaryPurpose: PREVENTION masking: TRIPLE whoMasked: CARE_PROVIDER whoMasked: INVESTIGATOR whoMasked: OUTCOMES_ASSESSOR count: 224 type: ESTIMATED name: Exercise Modes measure: Systolic Blood Pressure (16wks) measure: Systolic Blood Pressure (20wks) measure: Systolic Blood Pressure (24wks) measure: Systolic Blood Pressure (28wks) measure: Systolic Blood Pressure (32wks) measure: Systolic Blood Pressure (36wks) measure: Maternal Cardiometabolic Risk (CMR) Score measure: Symptom Occurrence measure: Placental Efficiency measure: Birth Weight measure: Infant Cardiometabolic Risk (CMR) Score measure: Maternal Heart Rate (16wks) measure: Maternal Heart Rate (20wks) measure: Maternal Heart Rate (24wks) measure: Maternal Heart Rate (28wks) measure: Maternal Heart Rate (32wks) measure: Maternal Heart Rate (36wks) measure: Maternal Blood Pressure (16wks) measure: Maternal Blood Pressure (20wks) measure: Maternal Blood Pressure (24wks) measure: Maternal Blood Pressure (28wks) measure: Maternal Blood Pressure (32wks) measure: Maternal Blood Pressure (36wks) measure: Maternal Body Fat % (16wks) measure: Maternal Body Fat % (20wks) measure: Maternal Body Fat % (24wks) measure: Maternal Body Fat % (28wks) measure: Maternal Body Fat % (32wks) measure: Maternal Body Fat % (36wks) measure: Maternal Circumferences (16wks) measure: Maternal Circumferences (20wks) measure: Maternal Circumferences (24wks) measure: Maternal Circumferences (28wks) measure: Maternal Circumferences (32wks) measure: Maternal Circumferences (36wks) measure: Gestational Weight Gain measure: Delivery Mode measure: Maternal Blood Glucose (16wks) measure: Maternal Blood Glucose (20wks) measure: Maternal Blood Glucose (24wks) measure: Maternal Blood Glucose (28wks) measure: Maternal Blood Glucose (32wks) measure: Maternal Blood Glucose (36wks) measure: Maternal Blood Lipids (16wks) measure: Maternal Blood Lipids (20wks) measure: Maternal Blood Lipids (24wks) measure: Maternal Blood Lipids (28wks) measure: Maternal Blood Lipids (32wks) measure: Maternal Blood Lipids (36wks) measure: Maternal Plasma Inflammatory Markers (16wks) measure: Maternal Plasma Inflammatory Markers (20wks) measure: Maternal Plasma Inflammatory Markers (24wks) measure: Maternal Plasma Inflammatory Markers (28wks) measure: Maternal Plasma Inflammatory Markers (32wks) measure: Maternal Plasma Inflammatory Markers (36wks) measure: -omics Metabolites (16wks) measure: -omics Metabolites (20wks) measure: -omics Metabolites (24wks) measure: -omics Metabolites (28wks) measure: -omics Metabolites (32wks) measure: -omics Metabolites (36wks) measure: Cord Blood and Placental Inflammatory Markers measure: Cord Blood and Placental -omics Metabolites measure: Infant Body Morphometric Measures sex: FEMALE minimumAge: 18 Years maximumAge: 40 Years stdAges: ADULT hasResults: False
