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, RPE, 12-15) per week. These limits are the same as those that generated previous positive findings for our preliminary data. The AE group will exercise on aerobic machines (i.e. treadmill, elliptical, bicycle) for all of their sessions.
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. The RE group will perform 12-15 repetitions of 10-12 resistance exercises in a circuit, for 3 sets with rest period of 30-60 seconds between sets as needed.[100] Seated isokinetic exercise using Cybex 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 Cybex 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. The AERE group will switch 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 repeated repeat with different exercises.[106-108] The investigators will also calculate the metabolic minutes per week (METmin/wk) of all participants in order to account for potential differences in energy expenditure based on activity, though the dose of 150 min/wk at moderate intensity is held constant between exercise groups.
The Control group will participate in weekly sessions that focus on stretching, breathing, and healthy lifestyle.
