Study Details

Brief summary:

The purpose of this study is to compare the effects of aerobic (AE), resistance (RE), and combination (AERE) exercise throughout pregnancy on selected maternal and fetal/neonatal physiological variables in women at-risk for preeclampsia. The central hypothesis of this project is that exercise will decrease severity and occurrence of preeclampsia symptoms, thus improving maternal, pregnancy, and birth outcomes.

Aim 1. Determine the influence of different exercise modes during pregnancy at risk of preeclampsia on maternal cardiometabolic health.

Aim 2. Determine the most effective exercise mode in pregnancy at risk of preeclampsia on improving birth and infant health outcomes.

Interventions and Outcome Measures

Arms

experimental: AE Group

The AE group will exercise on aerobic machines (i.e. treadmill, elliptical, bicycle)

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, RPE, 12-15) per week. These limits are the same as those that generated previous positive findings for our preliminary data.

experimental: RE Group

The RE group will perform 12-15 repetitions of 10-12 resistance exercises in a circuit, for 3 sets, with a rest period of 30-60 seconds between sets as needed.\[172\] Seated isokinetic exercise using resistance machines will target all major muscle groups. Light dumbbells and resistance bands will be used if the participant is unable to lift the minimal load on machines. Core exercises will be performed at the end of the session (i.e. seated side bends)

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, RPE, 12-15) per week. These limits are the same as those that generated previous positive findings for our preliminary data.

experimental: AERE Group

AERE group will alternate between AE exercise and RE; for this group, RE exercises will consist of 1 set of 12-15 repetitions of 4 resistance exercises, then 5 minutes of AE, then repeat this cycle with different exercises.

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, RPE, 12-15) per week. These limits are the same as those that generated previous positive findings for our preliminary data.

no intervention: Control

The Control group will participate in weekly sessions that focus on stretching, breathing, and healthy lifestyle.
